Blending New and Old Deck Boards
Here at DeckStainHelp.com, we strive to remain the Internet’s number one reference for your deck stain questions, opinions, and reviews. In this updated article, we suggest how to blend new and old deck boards for a beautiful even surface. We would like to hear what you think, so feel free to leave a comment below.
New and Old Deck Boards
There are many reasons why you would have a mix of new and old deck boards but it can be a common situation. The most frequent reason is that some of the boards needed to be replaced due to decay or wood rot while other boards were still in good condition. It is also very common for a deck owner to protect the deck with a stain once all the repairs have been made. The dilemma is that new boards and old boards look very different when they are stained.
To understand why this happens may help you to minimize the problem. Once old deck boards weather, the top layer of wood fibers begin to gray and become soft. Newer deck boards are denser and are very hard. The older boards will absorb more deck stain and appear much darker than the new denser deck boards which appear lighter.
To better blend new and old deck boards, it is necessary to wash the entire deck. Use a good wood cleaner and a pressure washer to remove any dirt, mold, mildew, and graying from the older deck boards. The newer deck boards will normally have mill glaze on them which can prevent good stain penetration. Use the same method to clean all the new boards as well to remove any mill glaze.
Cleaning the entire deck in this manner will also help the new coat of deck stain perform better. A clean wood surface prepped correctly will ensure better performance, coverage, and lasting protection.
After cleaning the wood, apply a wood brightener to the deck. A wood brightener will lighten all the older darker boards and open the wood pores of the newer deck boards for better stain penetration. This step can help a lot when trying to blend new and old deck boards.
It can also help to sand the boards once the deck is clean and dry. Sanding the old wood boards will remove additional soft wood fibers to create a harder surface. Sanding newer already dense boards will have the opposite effect and soften the wood fibers up a little and remove any mill glaze that cleaning did not.
In addition to these steps for blending new and old deck boards, using a quality semi-transparent deck stain will help. Follow these prepping and staining tips and your newly repaired deck will not only be safer, but it will also definitely look better as well.

Here is a picture of a repaired deck. Red part is painted but the owner wants it all stained to match. How can I achieve this?
How can I match this in a stain…red part painted.
FYI, you cannot stain new wood right away: https://www.deckstainhelp.com/staining-a-new-deck/
Do you want a solid stain or semi-transparent stain?
Is it best to paint the old and new deck boards
I have a mahogany deck that has a few replacement boards and the whole deck is ready to be stained. Will adding a 2nd coat to new boards help blend the color or will it just lead to over application?
Will not blend by adding more stain to the new boards and will be over-applied as well.
Hi, the guy who helped me refurbish my deck has already cleaned and stained and the new boards he replaced look way different Than the old ones. I’m not sure if he cleaned and prepared the new boards the same as the old ones. At this point, is there anything I can do to blend? Add Another coat?
No, not possible to blend at this point.
Hi, I am in Toronto Canada. I have a slight dilemma that I hope you could advise on regarding staining my new pressure treated deck, which was built having the cut ends of each board sealed, which I expect is normally a good thing except some of the clear sealer was unfortunately lapped onto some surface areas. So I had some concerns when it comes to staining to ensure the stain absorbs and the lap marks are the least noticeable as possible. My questions essentially are:
1) How long would be too long for weathering? is there a suitable amount of time I can wait before staining (not so long that the non sealed wood starts to deteriorate, but long enough that the sealed portions will absorb new stain) ?
2) Or instead, should I sand the problem areas instead of waiting too long?
3) Which stain might be able to cover over the sealed sections most unnoticeably? Preferably water based.
The deck was finished 10 days ago (Aug 2nd)
Wood: MicroPro Sienna pressure treated wood.
The deck is in full sun.
The sealer used on the cut portions was “Wolman Clear Wood Preservative with water repellent” (an older oil based product).
The MicroPro Sienna website says 2 – 8 week wait is sufficient as long as wood is dry to the touch, unless the stain manufacturer says otherwise.
I am considering whether to wait until the end of May 2020 to stain it (about 10 or so months), or sand the problem areas now before staining this September (past mid Sept will be too cold). I was planning to use a semi-transparent water based stain if I can find the most appropriate brand … the sealer was however oil based.
Any advice would be greatly appreciated.
Thanks
1. See this: https://www.deckstainhelp.com/staining-a-new-deck/
2. Sand off now and then let wood weather.
3. You cannot stain this now. Look at Defy Extreme if you want to use a water-based stain.
They are wrong on the weathering. Needs 3+ months. Sand now, prep and stain in the Spring is best.
Thanks very much for the advice!
Welcome
I have some deck areas that have pressure treated boards and others with cedar boards. Is there a way to reduce the redness of the PT boards so they stain more closely to the cedar boards?
No, that is not possible.
Does it make any difference whether you add new wood boards before stripping, cleaning and brightening an old cedar deck, or should you add them after?
Add them first.
Thanks. I’ve got to say, you have been the best help of any source I’ve turned to for advice on my deck work. Really appreciate it! Forgot to mention in my last question, I’ll be using a solid stain so I believe the new board/old boards difference will not be as apparent, other than checking in some of the old. Am I right?
Correct.
Our front porch had planters on the ends and the treated deck boards were never treated. We removed the planters and the wood under them looks newer. We would like to stain the wood now, using a Cabot product that is semi transparent. We plan on prepping the entire surface. Should I do anything different to the newer looking areas? Thanks
Nothing you can do to those areas so it blends with the rest of the wood. It will stand out slightly when you stain.
I am in much need of advice. We purchased a house with a 2nd story deck that seems to be pretty old and has a solid red paint. Last October I added a set up stairs with pretreated wood but was waiting to seal it, then this summer I replaced all of the boards with pretreated wood on the deck because of splintering and rot but I kept the support structure and railings because all of that was in good shape but it is still all red. I know I need to wait a couple of months to stain or paint the new boards. What is my best course of actions for the next steps to get everything to match(ish)? My plan was to try and power wash the existing red off but from there I am lost as to what to do because of the big difference in the age of wood between the boards/stairs and the structure. I am assuming the older wood is too old to stain but is it wrong to paint the new wood?
This is a picture
The only way to the red paint is to sand. Pressure washing will not remove it. The best course of actions is to go with a two-toned deck: https://www.deckstainhelp.com/why-have-a-two-toned-deck/
I have a deck that I built and stained 3 years ago with a (supposedly) 6 year semi-transparent stain. Since then I’ve had a deckboard or two split and crack so I replaced those boards today with new wood. I stained a sample piece of the new wood (see the orange-ish 2 ft. section lying in the one picture) with the same stain that I used 3 years ago but it doesn’t match my existing deck boards closely at all. The current deck boards aren’t in terrible shape so I’m thinking that stripping them probably isn’t necessary, but what steps would you recommend I do to get these new boards matching the old as best as possible? Thanks in advance.
Here are the pictures.
If switching brands of stain you will have to strip. New wood needs to season as well: https://www.deckstainhelp.com/staining-a-new-deck/
It will be virtually impossible to blend these new and old boards when using a semi-transparent stain.
What is the best brightener? I have a super clean deck but very dark, i need something that really brightens the wood.
Brighteners are designed to neutralize and brighten the wood after using a deck cleaner or stain stripper. They do not work as standalone products to lighten the wood’s natural tones. You can try it but no guarantee it will do anything. Try the RAD Wood Brightener.
Pictures for my comment below. The boards at the top and bottom of the picture are the new boards that I stained, the board at top of pic I sanded with 150 grit to see if that would help…it didn’t. The other picture is the “before.” Thanks!
You will not be able to get the new wood to match the older wood in this scenario. Nothing you do will make it blend when using a transparent stain. The brand new wood is just not absorbent enough to accept the stain the same way as the older wood.
Thank you so sand off or leave it alone?
Hi, novice here. I have a pressure treated deck and hired someone to stain. They replaced 2 boards and I am trying to get a stain that somewhat matches because the mismatch is driving me crazy. I have a semi transparent cedar stain down, they also put on new boards which turned yellow. I tried different stains to get to match, and it seemed I needed to go really dark, so I applied Moorish teak opaque oil based. Looked okay until it dried. I sanded one of the boards with 150 grit, only made it worse. Some dried a bit shiny which makes me think it didn’t absorb. Glad I found your site!
Questions:
1) should I try to brush paint thinner on these boards to decrease the darkness?
2) should I try to sand off with belt sander and apply another stain?
3) Should I sand some off and put another stain down?
Thanks in advance for your help. I will post pictures in another post because I don’t think my previous post worked with pictures. Thanks!!
When blending new and old deck boards together do you still have to wait months to stain the new boards? It seems kind of crazy to stain all the older boards and railings and not the new boards? Please help! Our handyman who is going to be doing the job is not quite sure himself which way to proceed?
If you stain the new boards without weathering, you will most likely have to apply another coat to those boards on 6-12 months.
Thank You
I have a deck that was improperly painted with an opaque stain (probably Behr) by the previous homeowner the year I got my house. It started flaking off within a few months. Fast forward several years and it’s time to do it right!! I’ve taken off all the flaking stain that I could so it would dry and will sand off the rest with a drum sander and edger. There will be some wood that will need to be replaced. I’m interested in using Restore-A-Deck Wood Stain. Do I need to use a cleaner and brightener before I stain or is the complete sanding sufficient? Thank you for this website; as a first timer, the information here and the accessibility of its presentation has been very helpful.
Do not sand with a grit finer than 80. Clean and brighten for the prep after. This will help the new stain to soak in deeper. You may only want to apply 1 coat of the RAD stain this time around. Another light coat to the floors in 12-24 months.
Thank you. Time to put the order in! Having spent an hour or two reading Q&As on your website, I’m still not clear on a few things:
1) Do I need to let the sanded wood weather before I do the clean, brighten, and stain? Or can I do it as soon as weather permits? It seems I read both options as viable. And that said, do I need to time it so all 3 tasks get done within a few days of each other? (I don’t know the waiting time or the effort involved in the clean and brighten steps).
2) Same for the new wood: one commentary said to let it weather, then do the clean, brighten, and stain. Another said to sand it along with the rest of the deck and go ahead and prep and stain it along with everything else.
3) once all is done, would it be wisest to NOT put down an outside rug? I read about rug outlines. I never had that with the opaque stain, but am wondering if it would interfere with the natural weathering that I’m guessing will take place, especially the first year after applying the Restore-A-Deck Wood Stain.
Thank you again for your help. It is a life-saver and great anxiety reducer!!!
1. Either. Weathering after fine grit sanding is suggested. If not weathering, do it all within a week or so.
2. New needs to weather: https://www.deckstainhelp.com/staining-a-new-deck/
3. Rugs will cause inconsistent fading when using a semi-transparent. Not really an issue if the rug is always in the same place.
‘weathering after fine grit sanding is suggested.’ I thought one did not use fine grit when sanding because it made the wood pores less penetratable, but did all the sanding with the 60 to 80 coarse grit sandpaper.
Correct but not all follow the sanding directions and sand too fine. If you sand with no more than 60-80 than you should be okay. Your new wood is an issue though and that needs to weather.
Can you hear me yell “Arghhh!”? It became clear after 3 hours of sanding with a drum sander that it would take several days to get the crappy (Behr) solid stain removed, if I was lucky. Plus after reading other comments about using pressure washing, stain removing products, and sanding and still not getting it all off, I realized the time and money would be better spent on new pressure treated wood. An improvement since the current deck was rotting on a number of boards and likely not PT. I even briefly contemplated composite decking (there is some the same price as PT wood) until I read the really bad reviews. I suppose I could have painted over all the blotches with a better solid stain, but I feel really untrusting of opaque stains and am wanting just wood and a semi-transparent stain. So soon I will have a new deck of PT fir/hemlock in WA state with some hot afternoon sun for our brief summer, and lots of wet for the rest of the year. Current deck gets some algal growth. Not too much traffic, but lots of pots (on wheeled plant caddies). I was aiming for RAD. I like everything you say about it and am drawn to the eco formula. But I’m wondering if an oil based stain would be better? Or if it doesn’t really matter which I use. Thanks. And yes, I will let it weather for the appropriate period of time before prepping and staining.
RAD would work well. If you want oil based, try Armstrong Clark.
I’m still here! Just purchased the PT douglas fir decking at my local lumber store and they were adamant that it did not need to be stained; that the pressure treatment chemicals are filling any available pore space already. And yet on your website I’ve read repeatedly about staining PT wood. Mostly pine–don’t know if that makes a difference. I am also thinking that if I don’t stain now, in a few years of weathering, staining might be needed, as well as possible. What are your thoughts on this?
You have to stain PTP and not it does not fill the pores. They are a little clueless there. Treat like new wood: https://www.deckstainhelp.com/staining-a-new-deck/
When restaining a fence with old panels and new panels…how do you make the stain be the same color
Prep all with a deck cleaner and then a wood brightener. Stain with a semi-solid color so it blends better. Try the Armstrong Clark Wood Stain.
Great read. Thanks for putting this post together.
Question in redwood decking. I am in a new build home (Colorado, so sun and snow through the winter) withmall redwood deck. Been here 6 months, haven’t stained or treated the deck. I’d like to extend the deck but am trying to set my expectations for how that will look.
With no staining or seal on the original deck it’s now greyish after 6 months. If I add new redwood decking to extend it, should I let it get a similar weathered look through the winter and then in the Spring power wash and seal or stain? Should I do something to the current deck to stop the weathering so that the new addition can catch up? What’s my best bet for matching those colors and then protecting a redwood deck (I like the natural color so I wasn’t planning on any colored stain)?
Yes. Add now, let weather, and prep/stain in the Spring. You must have a color in your stain if you want UV protection from graying. Clea will not filter the UV graying. Look at one of these semi-transparent brands: https://www.deckstainhelp.com/the-5-best-deck-stain-reviews-and-ratings/
Hi there!
Your posting and responses are very helpful! We have an old deck (~20 yrs old). We prepped it by power washing and sanding and deck cleaner. We are now staining with a semitransparent oil stain, using a pad. My question is, do we need to stain between the boards? Of course, a little bit has dripped down, but not sure if this is something we need to stain directly, I assume by taking a pad a running it along each edge.
Thank you!
Nicki
You do not have to stain between the boards but many do if you have wide gaps. Only for appearance.
Thank you so much for your response! I think we will end up doing so, only because the gaps are wide enough that you can otherwise see the drips. But based on your input, we will keep it to a very light coat!
I have replaced rotten boards on Deck. I have stripped and cleaned old stain. I want to put a water sealer on next. Can I do it now or do I need to wait 30 days and let the new boards dry out so they’ll be the same color. I’m afraid to let the old boards set too long without a water sealer.
Let it sit for 2-3 months and then prep before applying. https://www.deckstainhelp.com/staining-a-new-deck/
Everything has been power washed and restained. New replacement boards stick out like a sore thumb. Is there anything we can do besides just adding extra stain to new boards? Too late to start from scratch.
Adding more stain will not darken these boards to blend and will not soak into the wood. Just leave alone. They will blend next year when you redo.
Just had my deck restrained and the outline from the outdoor rug is still visible.
Is there a way to correct this?
Sorry but no. You could put the rug back in the exact same spot so it does not show.
Thanks.
AskHahahaha….that was actually funny! a Question or Post a Review…
We removed outdoor carpet from a pool deck that is 17 years old…Replaced a few boards and put up new railing.. Was surprised how good the deck looked under the carpet…it has always been carpeted. Now we are contemplating a sealer such as Rust-Oleum Restore. I’ve read nothing but bad reviews on this product. Suggestions for a good sealer? Any suggestion would be appreciated…My son is determined to use Restore…
Don’t use the Deck Restore by Rustoleum. If you want that look but have a product that actually works, try the Gulf Deck Revive: https://www.deckstainhelp.com/gulf-synthetics-deck-revive-review-2015/
We have a 5 year old pt pine deck, partially covered. Stained for first time 1 year after construction with semi solid oil based. 2 years later, sanded bare and restained with solid water based. Built pt pine privacy fence 6 months ago. Still unstained. Beginning to grey. Built addition to deck, onto uncovered portion 2 weeks ago. Still unstained. Would like advice on getting most uniform look to all surfaces. Planning on using oil based semi solid in a darker cedar or maybe walnut (something that will hide paw prints). Thanks
Sand off the old solid stain and brigthen the wood after. Clean and brighten all wood that is unstained. Use the Armstrong Clark in a semi-solid for all.
Can I successfully apply semi transparent or semi solid stain on this newly cleaned two year old deck? I prefer textured luck. My goal is to preserve wood from Midwest temperatures (uv rays and cold temps).
Yes, you can use a semi-solid or semi-transparent now.
We have old cedar deck. Stained every two years. We have totally sanded and ready to stain. Our boards are many different colors due to replacement. Plan to use semi-transparent stain. Do we need to use brightner 9brand?) and how long after using it do we stain? Thank you.
Clean and brighten for the final prep. Wait 48 hours to stain after the prep.
Can I use Yenkin Majestic Paint Stain on my deck over Cabots after pressure washing? Both are cedar in color.
Thank You, Scott
Sorry but do not know. Never used or heard of that brand.
what are the chances that the Armstrong semi solid deck stain will peel if the deck is properly cleaned.thanks
It is a penetrating stain so it does not peel when properly prepped and applied.
Spent the time and effort to properly prep deck for oil stain. Finished applying stain and wouldn’t you know it, rain, about 12 hours after I finished. That was a week ago. Can I simply reapply stain to the entire deck now that the weather is clear for several days? Please tell me I don’t have to prep all over again.
Depends on the brand of deck stain you used but you may need to remove all and start over.
As in whether or not the brand is the same? Can you elaborate what it depends on? Thanks
Depends on the brand and type you used? Not all are the same and how to fix varies.
I have a front and back deck made with PT pine, just replaced several old, damaged boards on both. Would it be wise to let the deck age and weather for around 10-12 months to get a more uniform blend between the boards before staining, or is that unnecessary? (Was thinking of a semi transparent for the front, possibly solid for back.)
If waiting is preferable, should I also wait to strip, clean and brighten until closer to staining time or go ahead and do that now?
Wait until Spring. Clean and brighten the wood then.
Thank you. My other question I forgot to mention was the back deck has some semi transparent that needs to come up. Does stripping take the place of cleaning, or will I need to strip, clean, then brighten?
Sorry if this has already been addressed elsewhere.
No need to use a cleaner is using a stain stripper. Brighten after.
We have spent weeks and lots of money getting solid stain off the deck. Finally done. We added an addition 5 years ago to a 10 year old deck after solid stain removed the newer side is still very much lighter. We have stained it thinking we could just add mote stain to newer side to make it darker. This has only made it redder than the other side we used dark walnut transparent stain. I don’t want to go through the stripping process again! Are there anyway to blend this with out solid stain or redoing?
Post a picture please.
Are you seeing this pic
No way to blend this with a semi-transparent stain at this point. Natural weathering and a recoat in a year or so and should blend then.
I have this situation (different aged wood) is semi transparent the best option?
Semi-solids will blend better. Try Armstrong Clark in one of their semi-solid colors.
what if i mix new boards and old boards , wash it, then solid color stain it? would that work better? Thanks.
Solid color stains will blend better but they can be prone to peeling.
I wish I had found this great site LAST weekend! I have a redwood deck of unknown age previously stained with a very dark purplish opaque stain. I pressure washed. The stain stayed in the few shady areas and in knots of the wood. I took out my belt sander to fix those areas (35 grit). The deck looks gorgeous. But after reading this site – oops! – What should I do now before staining? Or just PW, Brighten, stain?
Second, when do you know to replace the boards? I have 6 with minor surface cracks that go down about 1/4″. All are still as solid as their neighbors. And if I should replace, should I age the whole deck? THANKS for the help!
The boards sound like they do not need replacing. As for the stain, the only way to effectively remove a solid opaque stain is to sand it all off.
Just installed this new step and it’s raining for about a week before I installed. Should I wait until everything dries up to try to match the older boards or does it not matter? Also should I pressure wash everything then try to stain the older boards too? Thanks!
When to stain the new wood really depends on the stain brand you are using for the rest of the deck. I would suggest reading their directions. New wood, in general, should season and be prepped:
Have a treated deck, already stripped and used brightener… But looks like I should have replaced the rotted boards first oops…I was thinking of sanding the old boards to see if they would lighten up more(I prefer transparent stain and the color dif between new and old is still significant) so would I have to re brighten the deck?
Sanding will not lighten up the boards much or at all. You will have a slight difference between the new boards and the old boards no matter what the first time staining until the new boards become more absorbent.
I have an older deck that will need about 20% replacement of the deck boards. Is there a way to tell if they were PT or Cedar 2 X 6 boards? If PT, how to prep and stain to match old wood?
If pressure treated, it will most likely have a \”greenish\” hue on the inside if cut. Cedar has a light orange/red color and the smell is more aromatic if cut.
I have a deck that is all messed up, the whole thing needs to be sanded, stain stripped, and some boards definitely need to be replaced. Is this the correct order of operations:
1. Replace Boards
2. Stain strip
3. Sand (What grit? I have a power sander and brush, and was thinking for the more damaged poles and railings, to use the power sander, and for the furred deck boards, to use the brush.)
4. Brighten
5. Refinish/stain/everything else (I'll worry about this at a later date)
Yes that is correct.
Three new boards added to replace rotten ones. Deck has already had every thing done to it before new boards were added. Now a problem. What to do to the three boards to blend them in to old deck that will be acceptable. No thought was put into this issue when the decision to replace the boards due to safety issues.
Try to blend with a semi-solid color. Use Armstrong Clark stains. Prep well first.
Since I just found this article today, I was wondering if I need to go back and do the deck cleaner when I used a pressure washer and sanding the old boards.I did nothing to the new boards yet. Can I just sand them like the rest of the deck and then do the brightener or go back and follow your suggestions? It's been a lot of work sanding if I can get the same effect as the cleaner and then move on to the brightener–would be great news! Thanks!
Since you already started to sand it would be best to sand all so you will have an even appearance when staining. Do apply the brightener after the sanding. Rinse well with water.
Could you reckoned a deck brightener brand for me? Thanks for all the help too.
Restore A Deck products.
I have a cypress ceiing in my den that we put up 31 years ago. The ceiling also had box built cypress beams, which we recently removed. We whitewashed the ceiling and it is beautiful except for where the beams were. That area won't blend with the rest of the ceiling no matter what we do. Also, there is a dark line that seems to outline where the beams were. It is a slight line but we can't get rid of it. We have tried sanding, that made the differences show up more. We tried stripper, denatured alcohol, etc and nothing we do blends the two. Any help would be greatly appreciated. We are trying to find a solution other than having to spend a fortune to put new beams back up to cover the discolored wood.
You will not be able to remove this discoloration or get it all to blend.
I am staining my deck with 1501 cedartone. Some boards are a nice golden color and some are dull greyish after the application. The deck was powerwashed three weeks ago. Why do you think there is such a noticeable difference.
The wood itself is the issue, not the stain.
I am doing the final sanding on a cedar deck. Some of the boards have been replaced. The total deck has been sanded with a 60 grit. I have three questions:
1. what grit should I use for the final sanding?
2. do I still need to use the restore a deck products since I have removed the previous stain on the old boards?
3. my preference is to use a brush, do you have any other suggestions?
I will be using the Armstrong Clark Amber Stain
Thanks
1. 60-80 grit
2. Yes that would help the stain to absorb better.
3. Brush or stain pads for exterior wood.
I am trying to restore a 20 year old cedar deck (2×4). I have used a stripper and a power washer (turned down to about 1500 PSI) to remove the layers of old staing, mildew and crud. I'm having to also replace some of the boards due to rot. I have found some weathered old cedar boards at a used building supply store. The boards look very porous and grainy so I'm thinking of renting a drum floor sander to smooth out the deck. Should I still use a cleaner before I stain after I sand? BTW, I'm going to apply TWP 100 natural cedar semi transparent.
After the sand it would be best to use the cleaner.
Thanks, I thought so. Someone told me the cleaner would prepare the wood to receive the stain better. I going to use Behr Premium Wood Cleaner. Is that okay?
what is the best way to get semi-transparent stain off the vertical spindles (my are 1 inch square by 3 feet)?
Thanks!
John
Deck stripper and pressure wash off. Use the Restore A Deck Stripper or HD80 Stain stripper. Brighten the wood when done.
i have an old redwood fence that I'm attaching a new redwood trellis/posts. I was advised to use a semi transparent stain and I am planning on using the Arborwood brand but don't know what stain is going to match them both. I want something along the cedar or natural color. Do I need to buy two different colors of stain or will one work? I am getting it pressure washed and could put a brightener to it if necessary. any suggestions?
FYI. you might want to read our reviews and consumer comments on the Arborcoat: https://www.deckstainhelp.com/benjamin-moore-arbor…
Clean and or strip to make sure all wood is clean and free of any old coatings. Brighten the wood when done. It will not be exactly the same but hopefully close.
What grade of sandpaper would you use to sand old and new wood?
60 grit.
Question – Blending old and new deckboards. Undecided on final product. Completed cleaning of deck floor and stripping of old, oil-based stain that was mostly on the spindles. Next up: first sanding, then a brightening product. Haven't used a power sander before, but can rent one pretty cheap. Can an amateur power sander handle a heavy-duty sander without making a grievous, irreversible mistake? My deck nails/screws are countersunk fairly well, so I think I can go across them with no issues — at least, lightly. But how skilled to do you have to be to sand the entire floor evenly with no bad cuts?
You should be okay with a power sander. Just do not gauge the wood by trying to hard in certain areas.
Mixing new red cedar with old redwood. Should I sand before/after brightening and what grit sandpaper do you recommend for the new cedar and old redwood?
Sand first and brighten after. Rinse wood well with water. 80 or 60 grit paper.
Would it make sense to sand the New wood with a rougher grit (e.g. 60) to soften the fibers and the Old wood with a smoother grit (80) to harden the fibers? I was thinking this would help equalize the absorption since the old wood absorbs like a sponge and it lays on top of the new wood after sanding both samples with 100 grit.
Also, the new wood was laid 2 weeks ago and I cleaned/brightened 1 week ago. Should I wait and let the wood age before I sand and re-brighten or should I just sand and stain it now?
That will not equal it out. If you sand use the same grit for all. Have you read this about new wood: https://www.deckstainhelp.com/staining-a-new-deck/
I have a 6 year old deck, this will be my 3rd time staining, there are sections of the deck that the stain has peeled off. In the past I used a transparent stain, this time I believe the better road is to use solid stain. My question is after I power wash the deck what prep work do I need to complete to get one solid smooth colour on the whole deck. Also can you recommend a solid stain brand that will last more then one year.
Not sure what you mean about complete. Look at Flood solid color decking stains. Oil based stains will perform better.
Our deck has new and old wood so we used an solid stain. It started peeling so we have scraped, cleaned, and it has dried but we can't decide what product to use next. Any suggestions. We've ready many reviews of products but don't feel there are many good options. Has anyone used Duckback Superdeck Elastomeric Paint? Did it work? Can't find any reviews on it.
I'm in the same exact predicament. What did you decide? I was thinking about duckback also.
no offense, but this article doesn't address the issue suggested by the title, namely how to blend new and old deck boards. Doing what was put forth in the article will not blend them, generally speaking. If you really want a blend, then after doing what was suggested in the article, you are going to have to experiment with stains on the new boards primarily and then a protective coating over all of it.
