Update for 2019: Clean or Strip the Deck Stain?
We appreciate you visiting Deckstainhelp.com as we continue to be your go-to source for the latest in deck restoration news and trending topics through 2019. Below, we talk about whether you should Clean or Strip the Deck Stain? Feel free to leave a comment below with any pictures you may have.
Deck Stain Stripping vs. Deck Cleaning
Knowing the difference between deck stain stripping and deck cleaning can be vital to your deck maintenance or restoration project. It’s important first to understand why cleaning a wood surface is necessary.
Besides the obvious of overall appearance and curb appeal, a wood deck should be cleaned and sealed every couple of years to prevent structural damage. Water and moisture wreak havoc on wood inviting mold and mildew which can lead to wood rot. The sun’s U.V. rays also damage wood fibers and turn them an unsightly gray. In colder climates, freeze/thaw occurrences can warp, crack, and split boards ruining a deck in no time.
By cleaning the wood and protecting it with a quality wood stain, you are locking out moisture, blocking sun rays, and protecting the deck from the environment. This ensures a better overall appearance and a longer lasting wood structure.
Now that we have determined why cleaning a wood deck is necessary to let us uncover the differences between deck stain stripping and deck cleaning. Before applying any sealer to the wood it has to be cleaned properly. You need to use a deck cleaner to remove all the unwanted soils such as dirt, mold, mildew, and graying. This will guarantee a clean surface for the new deck stain.
The deck cleaner is mixed up as needed and normally applied with a pump sprayer. It should be allowed to dwell on the surface for several minutes to break up the unwanted soils. This is then followed up with a stiff brush scrubbing or light to moderate pressure washing to remove the contaminants. The deck is then rinsed and a deck brightener is applied to restore the pH of the wood and brighten the wood grain.
Failing Deck Stain
When an old failing wood stain or sealer is present a deck cleaner is usually not aggressive enough to remove it. In this case, using a deck stripper instead of a deck cleaner will not only remove unwanted soils but also unwanted stain or sealer remnants. Deck strippers are a more aggressive caustic than a deck cleaner. They emulsify and soften most deck stains so they can be washed away with all the other contaminants. The deck stripping process is the same as deck cleaning with the applying, dwelling, and pressure washing. The only difference is the product used and like mentioned, that is determined by what is existing on the deck prior to cleaning. A deck brighter should also be applied following deck stripping.
Basically, the difference between deck stain stripping and deck cleaning is whether or not there is an old deck stain present or you are just removing dirt, grime, graying, etc. Determine what is on the surface of your deck and use either the deck stain stripping or deck cleaning process, followed by deck brightening to prep the wood prior to staining.
As Questions Below If You Need Help
Hi, this is a great site – thank you for keeping it updated! I stained with Superdeck my fresh Doug fir in August last year after sanding. With a lot of rain over the winter, the deck darkened (expected) but there is also what appears to be sap droplets that squeezed out of the wood. Will the Superdeck Brightener work to remove that sap and not damage the coloring? Thanks.
No, that is impossible. Prep products will not remove sap. Anything you do will harm the coating and will result in the need for a new coat of stain.
Ok, thanks.
My deck was stained (the year after it was built) with Behr semi transparent 5 years ago.
The rails and sides of the deck are fine, but the floor of the deck and stairs have started to peel. I have been stripping it with Behr stain & finish stripper, scrubbing with a brush and also pressure washing it. Most has come off although there are spots that are really hard to remove (but I will work on it!!)
I intend to use the Behr woodcleaner (brightener) and then re-stain with a darker Behr semi transparent colour than previously used. Because I am using the same product, but darker colour, can I restain over the rails without stripping them?
Yes, but why would you want to use Behr again? it will peel again within the year. It has horrible reviews from us and consumers: https://www.deckstainhelp.com/behr-deck-stain-review/
Best to strip it all down and switch to a better and easier to maintain stain.
Hi. I want to apply a maintenance coat of Behr Premium Semi Transparent Stain to my deck. It is the same stain that is already on the deck. After cleaning the deck with a bleach type cleaner and pressure washer set with a 40 degree tip, there is some flaking and peeling. What are the next steps? Do I need to lightly sand or stip completely?
Strip it while pressure washing. Brightener after: https://www.deckstainhelp.com/restore-a-deck-stain-stripper-booster-thickening-gel-review/
I was afraid you would say that. Thank you so much for the help!
I was afraid you would say that. Thank you so much for the help!
I stripped the bold stain off my deck but now I need to sand since the pressure washing lifted some of the fibers. The wood appears to be back to its natural new color. Do I sand then clean and brighten or clean and brighten then sand? Do I need to clean and brighten ay all since it looks like new wood in color?
Just brighten after the sanding. Do not sand finer than 60-80 grit paper.
my husband applied oil based stain on our deck without removing any dirt from it and only did one coat saying the stain would cover it and it is such a bloody mess, what can I do to fix this?
You will need to remove and start over. How to remove depends on the stain brand and type of stain you used. Pictures would help as well.
I stained my deck two years ago with Behr semi transparent. I want to restain the deck with exactly the same product. The stain isn’t peeling, but has faded, where the sun hits it. I have read on other sites that I should do the water absorption test before staining. Do I need to clean the deck until the water test is successful, and the water is absorbed through the old stain? There are parts of the deck where the water would not absorb through the old stain.
Just use a deck cleaner for the prep and you should be okay.
Do I have to use a brightener if I sanded down to bare wood?
Clean and brighten after sanding is best.
Hello, old deck stain has been sanded off and I used oxygenated bleach to clean any lingering “green algae” from wood fibers. Will this as the same as a “brightener”?
No, that is a cleaner.
Hi, my husband just used a wood cleaner on our deck, and began painting with Superdeck Solid Stain in Chocolate color, 2 days ago. I don’t like the color, will stripping get it off? Or will I need to sand? We just bought our house, so no idea what was on there before. There was virtually no paint or sealer left.
After reading reviews it seems like cleaning, stripping & brightening is in order after I get the paint off.
Thank you!
A stripper will not remove a solid stain. You will need to power sand.
I used a Behr, semi-transparent all-in-one waterproofing stain and sealer 2 or 3 years ago. There are starting to be some spots of mildew and some spots where the stain has rubbed off a bit. Do I need to just clean it (with product?) or do I need to strip it all if I just want to reapply the same stain?
If using the same stain, clean the deck for the prep, not strip.
So if you are planning on using the same stain year in and year out all you need to do is use a deck cleaner and not strip it? And if just cleaning it do I need to use a wood brightener before restaining? Using Cabot Australian Timber Oil Jarah Brown.
And do you recommend using “Grace Vycor Deck Protector on joists? Was thinking of using roofing tar paper instead to protect against rot.
Yes, that is correct. Just use a deck cleaner for the prep.
Never heard of “Grace Vycor Deck Protector”.
Great! Thanks so much..really have learned a ton from your website..redoing my deck now after 9yrs the deck boards are rotted.. Hopefully with it covered now and doing yearly treatment it will last longer..
Do you recommend anything to protect the joists from rotting?
No need to do anything for the joists.
I used Behr semitransparent 8 years ago on my deck. The lower part has no stain on the floor but there is some stain on the verticals as well as the top deck. Should i use stripper on the top amd cleaner on the bottom or should I strip both top and bottom? I’ll be using RAd products.
Use the RAD stripper for all and then the RAD Brightener.
Thank you! Will send before and after pictures.
We have a deck that was stained with Sikkens semi transparent Cetol SRD stain. PPG now owns Sikkens and they can still order this stain for me and tint to my color even though I previously bought it at Home Depot (who doesn’t carry it anymore). We added onto our deck so we now have previously stained areas (worn on a lot of floor boards), new bare wood, and some hand rail both stained and not stained. Can I just clean and re stain it all with the same stuff?
Best to strip and remove so it applies evenly.
My deck has a semi-transparent natural cedar tone stain from over 2yrs. ago. I wanted to keep it looking good and deter carpenter bees by applying fresh stain. I pressure washed the surface and removed the old stain only in spots. I was under the impression this was adequate prep to apply a fresh coat of stain/sealant in a natural cedar tone. Now I’m concerned I didn’t strip old stain and didn’t use deck cleaner. Can I simply apply a fresh coat or what!? Thank you. It has been super hard trying to get the weather to line up w/ this project, and at this point I wish I just left it alone!
Picture please and are you using the same brand as previously or a different brand of stain?
I guess I made a huge mistake. It looked good before I used the pressure washer. It’s not the same brand from the first staining. What can I do? This can of Olympic says if it was semi-transparent it will be okay. I rented the pressure washer so I’m not doing that again. Help!
You would have to sand this all off down to the bare wood or use the same brand as before.
Why does it have to be same one? I am not sure exactly what one I used before, the can is gone. Happy project turned nightmare…I can try to return the one I have and guess at the one that was used over 2 yrs. ago. I am not able to sand it all off. I’m hoping you are right. I didn’t read the whole page on deck stain care–I just want to be able to keep it nice–not letting it go to crap before I attempt restoration. Jumped the gun presumably.
It most likely not penetrate and adhere if you do not use the same. Without proper prep, you will create a large mess that will be even harder to fix.
I just started staining my deck spindles and quite a few of them before I noticed the hardware store did not give me the exact color I wanted. The wood is brown treated wood. Will a deck stripper need to be used before I can restain? The stain I want to use is also a semi transparent, but is lighter than the one I applied.
Depends on the brand and type of stain you are using as to how to remove? It has to come off. Pictures would help as well.
It is Pittsburgh Ultra Advanced Stain & Sealant, semi-transparent
That is a water-based stain. Very hard to remove this, especially when just applied. Strippers will not work that well so sanding will be needed.
I hired someone to restain my deck. They are using Superdeck. Do they need to strip the old stain completely or just do a good deck cleaning and removing any loose stain by sanding and scrapping? I am under the impression that a full stripping is required however he is saying that sanding and scrapping loose stain to remove is sufficient and then placing the Superdeck stain over that is proper. Thank you!
If switching brands, you need to strip.
Hello I have a 9 year old pressure treated deck that we’ve applied Flood CWF-UV FLD420 Cedar Tone to twice. I’ve used Behr all-in-one wood cleaner and now need to re apply. I have 5 gallons (new) of the same stain and am wondering the process now. As mentioned the deck had the cleaner applied, scrubbed and pressure washed on low. Do I need the strip/brightener/sanding before applying or just apply? I have also read some articles that Flood should be applied in as thin a coat as possible and try to leave it as one coat instead of two, any thoughts? Last question, what would your prefered method of application be (brush, sprayer, etc.) FYI, The pics are of the deck after cleaner only. Thanks.
Best to follow their directions for applying and prep. We are not fans of their products anymore since they changed formulas and have not used it in many years because of it.
We are getting ready to redo our front porch railing, posts, and stairs. I have previously applied a dark brown solid stain (not sure of the brand). I am interested in changing the color to a dark gray solid, my question is it is necessary to strip it down or just clean it?
Also if I wanted to stain the stairs in a semi-transparent can I just clean and then sand? Or will I need to strip it?
Thank you!
You do not have to strip. Just remove the dirt and any loose, peeling stain. For the stairs, you will need to sand off the solid stain first.
I’m trying to find out if I need to strip with chemical or sand. I used sikkens semi transparent stain. Wanted to use same color but they don’t make exact but it’s close.
Strip first and sand if needed after to remove the rest. Brightener when done.
This PT deck is 15 yeas old. For several years, I applied a tinted sealant (Olympic) every 2-3 years but 2 years ago, I decided to change my approach and apply an oil-based stain (Beauti-tone oil based semi-transparent). I like the colour, but it flaked up big time this spring so I obviously didn’t prep it correctly last time, reapplied applied coats too quickly or something.
It’s especially bad around the pool.
If applying the exact same stain/colour this time, what prep is required? I have cleaned and scraped so far (in that order)
Do I need to use stripper? Brightener? Sanding?
Strip and sand it all down to the bare wood and then brightener is the correct prep.
I am wishing to go from a solid restorative deck paint (Olympic Rescue) to an oil based stain. The current product is coming off in sheets. We obviously did not prep it correctly 3 years ago.
What is the best preparation to go from paint to oil based stain?
The prep is not the issue but the product: https://www.deckstainhelp.com/olympic-rescue-it-review-2014/
The only way to remove this product is to power sand it off.
I have a client who wants his 5+ year old oil-stained deck cleaned before deciding if he wants to apply another coating of stain.
1. Is that a good idea? Won’t the wood just be more prone to damage after any type of cleaning and not applying any protective coat?
2. What would be the best cleaning method for his deck as to not remove any of the stain underneath the dirt and small amount of mold/mildew?
Thanks!
You cannot just “clean” and not remove some or most of the stain. He will need to restain. Best idea is to strip it all, brighten the wood, and reapply a new coat of the stain of his choice.
I have two different problems:
#1. we stripped our back deck a few years ago and applied behr water based semi transparent stain. We didn’t use a brightener and could tell immediately it wouldn’t last. We are now ready to redo the deck and wonder if we could strip it and then apply an oil based stain but I read your replies to other questions about having to stay with the same product. Of course we will not skip using the brightened this time!
#2. Our front deck has two coats of seriously durable paint on it (has lasted more than 10 years). We have never been brave enough to do anything to it but now want to try so it will match the back deck. Any possibility that this will work and hold an oil based stain?
Love your website, it has been so helpful!!
1. Answered this already on another post.
2. Sorry but no.
Just to clarify, if we strip and sand the paint off a stain would not work ?
If you remove the paint 100%, you can use a stain.
Hi. Stained cedar deck a couple of years ago with Wolmans Semi-Transparent. Replaced a few boards as well. Based on pics do I need to strip or “just” clean deck before applying same color and same brand and type of stain? Thanks!
This brand cannot be stripped. I believe it can be cleaned and reapplied but best to check with Wolmans.
Hi, We built a cedar deck about a year ago and applied Behr Premium Transparent Penetrating Oil Wood Finish (Cedar Naturaltone #4001) about 2 months after wood delivery. We sanded, and didn’t use any brighteners, etc, which I suspect is causing the uneven finish.
About a year later, the deck looks kinda uneven and splotchy. None of the stain is peeling, and most the deck still seems fairly well protected. But, we’d like to even the color out. What do you recommend? We like the initial look of the Behr product, but open to other finishes that will show the cedar wood grains.
While there is a bit of dirt/mud in the photos here, most of the discoloration seems to be in the wood/stain. I’ve tried pressure washing and cleaning with TSP and it looks the same before/after.
Thanks!
You cannot add another brand over the Behr so you will need to remove or apply the same brand.
Thanks – If I keep with the Behr to avoid removing stain, do you suggest cleaning and brightener? Or just clean and stain?
Thanks again!
Just clean.
I have a porch floor done with pressure treated lumber, used a semitransparent stain on it and it still looks good but after many years could use sprucing up. There are a few oil stains , really don’t know what to use to remove and do not want to sand the entire floor. Can I give it a real good cleaning, use the recommend oil stain remover and restain with the same product? Thank you for any assistance you can provide.
What brand was it? Post a picture please.
I used Australian timber oil semi trans stain on a new deck after the proper drying time of the wood, after two years it looks like it needs redoing in the high traffic areas, but reading your site I see that spot staining is not recommended, if I want to use a water based stain instead of oil will I need to strip it off after this much time has passed
Yes you will have to strip this all off. Use the Restore a Deck Stripping Kits.
thanks I will let you know the results
I have a PT deck which was last stained with semi-solid Ben Moore Arbor Coat. (lasted almost 5 years).
Due to the age of the deck (17 years) I am going to apply Ben Moore Arbor coat in a solid.
I have cleaned and sanded the decking, and stripped a section to try to remove the last of the old stain – it’s not coming up.
The only way to get it to bare wood would be to continue to sand.
Do I need to go that far to apply the solid stain ?
No. You can cover this with a solid stain.
I used Spar Varnish on pressure treated wood. It was beautiful but two years later the varnish is flaking off. I liked the look of the Spar Varnish and am thinking of reapplying. Should I use a stripper to get the old layers off and if so, will a stripper harm the aluminum balusters?
You would have to sand this off.
I applied Thompson’s water seal (stain + sealer in one), solid, about 1 year ago. The exposed horizontal surfaces need restaining – see photos (some have tree shadows). I plan to apply 1 or 2 coats of same product to these surfaces. Should I just use a cleaner, or just pressure wash, or use a stripper? Thanks.
Use a stripper and then pressure wash off the loose stain.
I stained my deck last year but there are spots where the stain is flaking off. Just a few small areas, nothing major. We want to fix it but were never happy with the colour and want to stain it a darker colour. Would we need to strip it going to a darker stain?
You should strip and start over.
We have protected our deck with Thompson water seal for several years. It has become very dark and ugly. We would like to strip it and then seal it. Is there any product that removes Thompsons sealer. We haven’t found anything yet.
The Restore A Deck Stripper and pressure washing should remove it. I assume you mean the clear sealer? Brightener after to neutralize.
I’m not sure what brand/color of stain was used on our deck previously. Based on the attached photos can you tell me if we should use a stripper first and then sand down the rough areas before using a wood brightner, then stain?
Thank you for your help.
Hi Kim,
Yes, use a stain stripper first. Sand if needed and brighten after. Use the Restore a Deck Stripper and Brightener Kits.
Previous owners used a Cabot oil based solid stain in white. It’s been a few years and the deck clearly needs a new treatment (looks dingy, some mold). We’re novice DIYers and I’m looking for the easiest solution. Should I simply use the same product again? Should I use Restore-a-Deck cleaner & brightener first?
You will need a solid again. Prep with a deck cleaner and pressure washing. No need for the brightener.
Okay, so I finished the board replacement, but as you can see from the photos, it’s difficult to tell if this deck was ever stained. I’ve hit several small areas with the pressure washer and it looks to come pretty clean, but other areas look like they may have some stain on them. The railing slats, for example, look like they’ve got some stain, but they came pretty clean with the pressure washer. Based on these pics, would you recommend starting with a stripper, or a cleaner? It’s going to be about a $40 difference for me.
Best to use a stain stripper for this and then pressure wash off. Brighten all when done. Cost should be about the same with stripper vs cleaner.
Roger that. So no need for cleaner if I use a stripper. I assume you recommend RAD stripper, but I’m doing the job tomorrow and no time to order. Any recommendations from the big box stores?
No need for a cleaner if using a stain stripper. Nothing decent from big box stores. Try a local paint or hardware store.
i had a new pressure treated deck built 3 summers ago, waited a full year to stain the deck. Most of the deck still looks great but there are 3 or 4 boards that the stain seems to be flaking away. I’ve cleaned and re-stained endlessly but this keeps happening, usually after a heavy rain, and now after the winter it has all “pealed” away again. What am i doing wrong?
What brand of stain did you use? Can you post pictures?
Hi, I used Olympic stain. I am not home to take picture but will post one this weekend.
Here is the picture of the peeling. I will restain and this will happen after a heavy rain.
It is applied to thick to the point that the stain is not soaking into the wood but drying on top of the wood. You should sand and strip to remove it.
Thank you!
The previous owner applied SW Deckscapes in Sequoia about 4 years ago. The stain is wearing off on the floor, but not so much on the railings. Therefore, we want to re-stain our deck in the same color to make it easier. Do you recommend that we use a stripper and brightener? Or, just the cleaner? Thanks!
Same color and brand? To clean ot strip depends on how bad the wearing is. Can you post a picture?
Yes, we would use the same color and brand for the stain. Here are pictures of the deck. Is it necessary to remove all the stain? I assume the process would be power wash, apply stripper and then cleaner? Or, can I skip the stripper? Thank you!
For this, just clean and reapply the same. No need to remove all or use a stripper.
What color is your deck stained and paint type?
My deck was painted many years ago. Held up for many years but over the past few years constantly chilling etc. is it better to strip and return to natural color or just repaint it? Live on water and someone told me to strip etc. all the chemicals would go I️. Water and better to clean it and repaint?? I’m not sure. Help??
You cannot fully strip paint so if you want to remove, best to power sand. Another option is to pressure wash off loose paint and cover over with another paint. This is a temporary fix though as it will continue to peel.
Hi, You have some great helpful comments. I am wanting to find the cheapest way to fix our all redwood deck. For several years we stained it with a semi transparent redwood stain to bring out the red and the wood grain. But 2 years ago it was accidentally ‘painted’ with a non transparent “filler” that covers all the grain a left if very rough (so it keeps dust and dirt even with scrubbing). I hate this so much, I am even considering rebuilding the whole deck with something I never have to worry about mistakes on (ie composite) but that is expensive. SO I am thinking I will have to try to hire someone to sand off all the old stuff. But this stuff it tough…it was advertised as a paintable wood filler for cracks up to 1/4″ and it is the all over the deck, spindles, arm banisters, etc. Would it be cheaper to just replace deck (even with treated lumber and restain) or just try to sand and work this one…I really want to keep the redwood if I can.
Without seeing a picture or knowing the brand of paint you used, it is hard to say what would be easier or cheaper. Definitely easier to replace than to try to sand this off. Probably more costly though.
What is the best stripper for removing Sikkens Cetol? The deck has about 30 years of Sikkens which had been merely reapplied every 5 years or so, without stripping the previous coats. The worst part is that the original coat of Sikkens was applied over a dark red stain on very light wood. I’m having an awful time. Also, they want me to apply Sikkens SRD or SDR. I was wondering is there something I can put over the top of this Sikkens application to ensure longevity? I’ve heard only bad things about SDR in this Florida humidity.
You will need to sand to remove this many coats of the Sikkns Cetol. Strippers will not remove it fully. You cannot extend the life by adding something on top.
Sweet Jesus…our painters used the wrong color stain on our Ipe deck. The deck is 5 years old. Was stained 5 years ago with one coat of Sikkens oil based. It was in need of a fresh application because it had gone fairly gray in areas. They cleaned and brightened it and then put the wrong color on. Do we have to totally strip it and re-stain. They used Sikkens ProLuxe Cetol oil based. Can that even be done with fresh stain?
You will most likley need to strip and power sand to fully remove it. Sikkens Cetol is not easy to remove, especially when freshily installed.
Spotted gum deck stripped cleaned & sanded still beading
Not sure what your question is?
Good Morning,
4 years ago we bought a house with a large deck. It need to be retreated. I bought a stain and put it on the deck. It started to peel with in 6 months. Someone told me it was because the owner before us used a oil base. So i need to redo our deck. What do i need to do? Should i strip it, we have lots of little pedal stalls on the railing that are fine. What do you suggest I do?
Best to remove. Strip or sand it off. Brighten the wood after.
I have a deck over my walk out basement with steps leading down to the lower deck (used to surround a pool but we removed the pool and filled in with wood) or continuing to the basement level. We have stained the newly built deck already with Olympic Maximum semi-transparent stain and it looks great! We matched the color to the old deck stain as closely as possible and it is close but we want to recoat the upper deck and steps as there is some wear and tear. I have researched pretty in depth and have found I do not need to strip the old wood since it is also a water based semi-transparent but the steps have some peeling. I cleaned and sanded all weathered areas and have a pretty smooth surface now. Should I still strip the steps since they were peeling or just stain since it is sanded smooth?
You have to strip if switching brands and remove all of the previous coating. No way around it.
Hi There,
I have a new Cedar Deck I have installed. It has been seasoned (installed) almost 3 months. I feel I should stain it before winter (Michigan). I have purchased Sherwin Williams Deck Revive to prep the wood before staining. Is this product not advised because it is bleached based? Am I ok to proceed? Thank you for your assistance in advance
We are not fans of the SW prep but it is probably okay for the first time.
Thank you for your reply and advice. What is the best applicator for the stain? I am using an oil based transparent stain. The deck is roughly 800 sq feet. I am hesitant to get on my knees and brush the whole deck. But I am also under the impression that a brush and then back brushing is the most thorough and best way to apply the stain verses spraying, a rag, or a pad. Thank you again.
Use an exterior stain pad.
I have a real mess on my front deck. I purchased Australian Timber Oil thinking it was a great product, recommended by my local Ace Hardware, and it looks awful. It was very thick to apply, did not absorb into the wood, and right after application it picked up all footprints, dirt, etc. The finish now looks continually dirty and muddy. I tried power washing, scrubbing, etc. but nothing is working. Is there a product I can use to fix this or must I remove it and re stain the deck with something else? I applied it over existing semi-solid stain after power washing.
The reason this happened is that the Cabot ATO cannot be applied over a different brand of semi-solid stain. It had no chance of soaking into the wood. At this point, you must fully sand to remove all and start over.
Thank you.
I am DESPERATE to fix a huge problem regarding stripping my back deck (and I can pretty much guarantee you have never run into this issue before!). About 4 years ago my sister and I bought a house and stained the back deck (I think it was an oil based product, but can’t remember for sure). Over the past 4 years it became very weathered with no color or protection from the heavy rains we get in WA., so we wanted to apply a fresh stain before fall/winter set in. Somebody I know recommended using [water based]ATCO SW1 Shake and Wood Treatment (yes, you read that right, a roofing product). It looked great when we applied it to the deck, but it never absorbed. When you walk on the deck the bottoms of your shoes will turn the color of the deck (and it was even tracking in to the house). We had some light rain the other day, and the whole deck looked like it had wet paint setting on it! I’ thinking maybe the water based ATCO product didn’t take since we didn’t really properly prep the deck, and there may have been some of the previous oil based stain on it (even tho the wood looked worn and bare), After a lot of reading, I decided to strip it with [water based] DEFY wood stripper (and then follow up with their wood brightener), so we could start all over with a fresh stain. Now, after a chat session with DEFY they’re telling me the wood stripper probably won’t work since the roof stain product was applied only 6-8 weeks ago, and I will most likely have to sand it all off. PLEASE tell me there is another fix for this problem….
P.S. I already spoke with the dealer where I bought the ATCO SW1 product, and they were of on help – basically told me to call Home Depot and get info on a stripper product.
Sorry but only options are to sand this off or replace the wood.
Is it even worth trying the wood stripper and/or a bleach-detergent-water solution with a pressure washer?
Probably will not work.
Last question ~ If there is no getting around sanding, what type sander would you recommend (electric palm sander or orbital). Also, should I use 60 or 80 grit sandpaper?
Drum sander and floor edger. Use 60 and then 80 grit.
We applied Thompson Water Seal to our deck last year, it no longer beads. We are planning on applying stain. Do we need to strip the stain first if it no longer beads?
You should strip and brighten.
Thank you for your help.
Hello, I have Thompson tinted water seal on my deck and want to apply solid Behr stain on it. Most of the water seal has worn off but the spindles and sides still bead water. Do I need to strip it or can I just clean it and apply the stain? Thank you
Just pressure wash if you want to go with a solid stain.
I have pressure washed my desk several times and there is still some stain on a few areas that I can not get off. Would it look ok if I stained with a darker stain (or same color stain)?
It would have to be the same brand as last used.
Our deck was stained with a semitransparent stain 2yrs ago. The stain has worn off in certain spots and we just want to do “touch ups” instead of stripping the entire deck. Can we just use a deck cleaner and then stain the spots in question? Should we use a brightened as well? Thanks!!
It is not good idea to spot prep and stain. It will not look good. Best to prep all and stain all.
