Common Questions About Wood Deck Stain Strippers
Do You Have to Strip a Deck?
Prior to staining a wood deck, it is necessary to properly prep the wood for the best results. Removing all the dirt, mold, mildew, and graying will help the new deck stain to penetrate better and last longer.
When dealing with a deck that has an old failing deck stain on it, a simple wood cleaning is not enough. In this case, a deck stain stripper must be used to emulsify and soften the old stain so it can be removed more easily. Wood stain strippers are more aggressive than a typical wood cleaner.
What are Active Ingredients in a Deck Stain Stripper?
Some of the best deck stain strippers that we have found contain a mixture of Sodium Hydroxide and other surfactants and typically come in a concentrated powder formula. Once mixed with water they can be applied using a pump sprayer.
Instruction Tips for Stripping a Deck?
To get the best results using a wood stain stripper you need to let the product dwell for several minutes after applying it to the wood. This allows the stain stripper to penetrate and break down the old stain. The amount of dwell time depends on the type of existing stain. For instance, most semi-transparent oil-based stains will remove more easily than a semi-solid deck stain.
For hard-to-remove stains such as acrylic or silicone-based stains, several applications and longer dwell times may be necessary. In extreme cases when dealing with a solid deck stain or paint, some sanding may be needed to fully remove the existing stain.
Once the failing deck stain seems to have been softened it is best removed with a power washer using light to moderate pressure. The caustic stripper will raise the pH level of the wood during the stripping process causing it to appear very dark.
Do I have to Brighten after using Deck Stain Strippers?
Following the stripping process with an application of a wood deck brightener will restore the pH, brighten the wood, while neutralizing the deck stripper. This brightening process should not be skipped. It is a crucial step to getting optimal results from the new deck stain and a more natural appearance.
Using a quality wood deck stain stripper will give you the best chance of removing the existing deck stain. Once the old stain is gone the new deck stain can fully penetrate the wood for maximum protection and lasting results.
I have a 24 sq. ft. “Stoop” + one step, that needs attention. I bought the condo 7 years ago and have no idea what the previous owner put down. I’m hoping you can tell from the photo. I really don’t want to rent a power washer for such a small area. What would you recommend? Thank you!
Pressure washing while using a stripper and brightener is the easiest solution. Other option is to power sand:

We just had two decks stained with Cabot Semi Transparent Redwood stain. It seems like the stain was applied very heavily as it is shiny and tacky. It almost looks like paint. It makes the wood very hot and slippery. What is the best solution at this point? One of the decks surrounds a pool.
To fix you would have to power sand this all off.
Oof. Ok, is that what you would recommend given the photos?
If the stickiness does not go away then yes.
And can you explain why sanding vs any kind of stripper or a combination of the two?
Strippers will not work very well with a newly and over-applied stain like this.
If we have a stained deck with a painted coat which is the best stripper ti take care of both to eventually restain?
You will have to power sand to remove this.
I am so glad to finally find your site! I am a single woman with a home in a temperate rainforest climate with a large UNOCOVERED deck. I have only had the home for 2 years and the deck “looked” pristine when I got it. Now it has severely deteriorated – lots of cracks, peeling, lifting, etc. I believe the previous owner went over it with Valspar 1 Coat Exterior Stain and Sealant Opaque Solid (found leftover) without any prep to make it appear good to sell.. I have someone to refinish it for me but they want me to choose the process and materials.
The deck itself is pressure treated wood and approximately 10-12 yrs old.
With information from your site and other research, I think I would like to strip the floor, recondition it and apply a semi transparent stain in a redwood color to coordinate with the pickets and rails. The pickets look perfect and the rails have some splitting and mold but are otherwise in good shape. I would like to refinish just the rails with the Valspar product and leave the pickets alone.
Please help! (in the last pic, we tried a stripper as a test. we also pressure washed) Thank you!

I stripped and redid my deck last year with a lot of great help from this site. I’m very happy because this deck gets a lot of wear and rainy cold winters. What should I do this year. I need to clean it for summer and a few areas did flake. I’d like to fix those. Thoughts for my spring.

Looking for recommendations to strip and restain 800sq ft deck. Existing coating is Thompsons semi transparent. Deck is on second level supported by painted structural beams. Is stripper going to damage the painted beams. Will restore a deck do the job. Please advise
What you have on the wood is more of an opaque solid stain. Thompsons lies about their opacity. Problem is that a deck stripper will not remove this fully. You can strip off as much as possible but then you will need to sand to get it all off. You would have to do this if you want to use a proper semi-transparent stain. The other option is to remove what is peeling and then cover the rest with a solid color stain. https://www.deckstainhelp.com/how-to-reapply-a-solid-color-deck-stain/
Scott- very recently had a small deck restained with a Sherwin Williams oil-based stain to a cedar color (see 1st picture) that is too orange for my liking. Would like to remove that stain so i can reapply a more clear finish to get closer to the more natural cedar color (see 2nd photo). So 3 questions: (1) Will the restore-a-deck stain stripper and booster products do the trick for this job, or will I need to consider sanding as well? (2) Any recs on a clear stain product and color? (3) Will a clear stain, baked in Minnesota sun, evolve into a color I’m not expecting? So maybe the orange cedar I’m seeing today is not as undesireable as I think? Thank you!
1. It should remove all or most. Make sure to pressure wash.
2. Clear sealers = zero UV protection. It has to be tinted.
3. Clear will turn gray in months.
Very helpful. Thank you!
How long is too long? In early July I used Restore-A-Deck stripper and brightener on my 1000 sf redwood deck. (I built it in 1985 and re-finish it every year or so.) Did a good job and all looked great. Then life and vacation and rain and weekends on the river and repairing some soft areas and sanding the railings all got in the way — and I have not refinished it yet — the naked wood looks great when wet – the rest of the time it looks hungry. I have always refinished with transparent or “natural” finishes. Right now I have 5 gal of Cabot Australian Timber Oil finish, Natural, sitting here ready to go when things dry out. My question is: given the 2 months that have passed since the cleaning/brightening — am I still ok to apply the finish, or should I “brighten” it again? Thanks.
Clean and brighten again.
Customer used this thick ‘correct deck stain’. But he stained over top of a clear sealer ,of course it’s bubbling n flaking all over. Whats best stripper for this type job? I got half it off just pressure washing.
You cannot strip that coating type. Sanding is the only way and it is not easy.
Yep sanding my butt off , gottta be better way in life. Lol
Thompsons Deck stripper with sodium hydroxide. will it harm the deck hardware and concrete? and it will be rinsed into into the soil below it which will also down the slope of terraced rocks and plantings, and stream water. Is this OK? We will be using about 3 gallons.
Strippers will not harm concrete or deck hardware. The ground should be fine as well.
I read California states sodium hydroxide causes cancer and birth defects. In our case a stream runs under one of the decks through which the stripper will be rinsed. There is ground under the other deck adjoined to the home, but the stripper will soak into the ground and eventually through to the stream. WE live on an island.
Too much exposure to anything can cause issues. You will be fine when only stripping your deck once but you can always sand the deck if concerned.
I used Sikkens on my deck 4 years ago. There is only one coat on the deck. It’s looking pretty rough so I decided to restain it. I pressure washed it which removed a lot of the colour right down to the wood, but there is still enough colour on there to make the deck look brown as opposed to natural wood colour. After reading your posts, I think I want to switch to the TWP 100, 200 in semi-translucent or semi-solid stain. Do I have to remove all the Sikkens first? If so, is the Restore-a-deck enough to pull all the stain up and off? Or should I sand the deck? If I have to sand the deck, would you recommend an orbital sander (I’ve used before and it was a hassle as the pads kept slipping), or a drum sander? And is it important to sand or get Restore-a-deck in the cracks and along the sides of the boards (the space between the boards)? I live in Victoria, BC, Canada and we get A LOT of rain here. Which one of the TWP products do you recommend for our climate? Thanks! Attaching pictures – it had just started raining so it looks very deceiving and uneven but it’s all I got. Sorry. Also fyi, one deck is cedar and the other is pressure treated wood. Your website is so informative. Much appreciated.
Yes, you have to remove the Sikkens fully and this cannot be stripped. You will have to power sand to get this all off. For Canada, you will need the TWP 200 Series.
I have a deck from Hell…have a 300ft PT lumber deck built 5 weeks ago. The Builder hired a painter who only uses Sherwin Williams products. He told me he was going to us SW Deck stain (gray). He did a horrible job and when he said he would fix it, we said no…
I found another painter who came out to look at the deck. He asked what was put on the deck and I told him…H&C® COLORTOP™ WATER-BASED SOLID COLOR CONCRETE STAIN. The original painter and his Sherwin Williams Representative highly recommended it.
Immediately, the painter said that he didn’t think the stain can be used on wood. Sure enough, the application instructions state it cannot be used on wood surfaces.
Ended up speaking to the SW District Manager and was told that they would fix it.
So, can you tell me what needs to be done to get the stain off? Do you recommend sanding or a Solvent? If a Solvant, is there anything you recommend? I’m thinking they will use a SW product…
I’m going to eventually have it painted. If a Solvent is used, do you recommend a light sanding before the Primer?
Really appreciate any help you can give me.
You will have to sand it all off. A solvent will not do anything. You do not use a primer before using a solid color deck stain and never use a paint on a deck.
Thank you for your reply. I know a Primer would never be used before applying a solid stain. I was referring to it when using paint on the deck. After this experience and the fact that the deck looks horrible with the “stain” that was used, we are leaning towards paint. I understand and appreciate your point of view on paint though.
Paint peels on decks and should never be used.
I have years of solid stains applied to my deck. Time to remove but most strippers don’t strip solid stains. Help!!!
Sanding is the only effective way to remove a solid stain.
i have a customer with a deck that is in fairly good condition. The previous person applied Thompson Waterseal Penetrating Timber Oil Cedar transparent stain. It is flaking off in places and is bonded well in others. I do not plan to use this product again, so i want to remove it. Will Restore A Deck stripper remove the Thompsons? Please advise
It should but use both RAD Stripper additives as well.
Deck is about 12 years old. Have used Sherwin Williams stain products all this time. I think Original stain was oil base because the water based stain never lasted. Nephew power washed deck and now a big mess! Should I try a stripper and then try sanding???
Post some pics fr prep help.
Hi I have decking that needs the old ronseal stain removed as it’s started to peel. Could you recommend the best stripper and then what steps you would then follow. The decking is next to some artificial turf so I want something that isn’t going to affect that at all.
Thanks
Post some pics for prep help.
Here you go
Use the RAD Stripper with both additives: https://www.deckstainhelp.com/restore-a-deck-stain-stripper-booster-thickening-gel-review/
Let dwell for 30+ minutes and then pressure wash off. RAD Brightener is last.
I found your site and I am thrilled! I hope you can help me. I stained my deck 2 years ago using Valspar semi transparent stain. I prepped the deck the same way I have for the last 20 years. Now it is peeling! Never happened before. The deck is right next to a pool so I have a problem with the location. 1. Do I sand or strip! 2. do you have any recommendations for me? 3. Once it is prepped, do you recommend I use a semi transparent stain again? I am a 69 year old woman. Is it time for me to hire this to be done by an expert? Thank you so much.
Strip off what you can and then sand the rest off. Brightener would be last. Once prepped, use a penetrating semi-transparent stain so this does not happen again.

Hi- I made a porch swing out of red oak. We put it into service May of 2021 (Original Photo). Photos Example 1,2 & 3 show the deterioration of the finish and mold spots that have developed. I used 1 coat of Cabot Semi-Transparent Deck Stain as the finish. The label on the product can recommended only a single coat. Because the finish dried a little rough, I then waxed the surface with a paste wax which smoothed the final finish.
I am hoping that you can give me some direction on what to do next.
There is nothing you can do next at this point. You cannot top coat as it will peel.
Hi I like the info on your website! Very helpful.
Can I use RAD on the siding of my home? I have a Pan Abode cedar home. I have areas where black spot mold has developed on the wood. I coated one side of my home in Sikkens SRD about 8 years ago, but I need to redo that side due to weather and spot mold areas. I would rather not sand it off, if RAD will work. Thanks in advance for your input.
Post some pictures for prep help.
Thanks for the response.
The wood is a combination of Pan Abode Cedar wood and then 6’x1.5″
I look forward to your input.
I’m thinking First-RAD Stripper/Brightener.
In addition both RAD additives for vertical siding, and to penetrate the mold and former oil base stain sheen coat from older reapplication coats.
I don’t see the using the cleaner if I’m just going to use Stripper on this removal. I’m thinking of going with a water base stain for the next round of stain. Suggestions?
This will not be an easy strip as removing a coating that has a shine, can be difficult. The RAD Stripper with both additives is your best option. It should dwell for 45-60 minutes before you pressure wash off. Brightener is last. No need for the cleaner. The RAD Semi-transparent stain would work very well after.
Thank You. So with the concept- difficulty of the shine, in mind would it be better if I did a reasonable pass with an orbital sander 60-80 grit to knock down the shine and then did the stripping? Or just longer dwell time and no sanding? Or will I have to scrub after I applying the Stripper to get into the mold? I do appreciate your input!
I do not think sanding first would help at all. The mold is not the issue, the shine is. The stripper needs to get through that to break the bond between the stain and the wood.
Good advice thanks! I ordered up on the RAD stripper, additives and stain. I’ll post my findings.
I have to spot treat with the RAD stripper. Some drip marks from a previous attempt to strip won’t come off with either cleaning or sanding. The areas needing treatment are vertical and really aren’t large enough to spray. Can I brush the product on? Thank you.
Post some pictures.
thanks
You can brush or spray it on. The brightener after stripping should help even this out as well.
An update….I ordered and received the RAD Stripper and Gel.
Wanting only to treat a small area, I mixed 1/2 cup of stripper into
1/2 gal of water and then 4 oz of gel. After two applications, and brushing,
my ‘drip’ stains remain. Can you offer any advice? I can send pictures once the wood dries. Thanks.
Did you try the brightener as the discoloration from the drips may be internal?
My boyfriend and I bought a house and don’t know what stain was used on our porch. Is it a solid stain? The elements have nearly gotten it off, and we would like to restain it to help us sell it. We’ve never done anything like this before and are not sure what product would work best to get the remainder of the old stain off with minimal sanding. Any advice??
Yes, it is a solid stain. You will need to apply another solid stain over it unless you want to power sand it all off.
https://www.deckstainhelp.com/what-are-the-best-solid-color-deck-stains/
We stained our deck 2 years ago and after reading all these comments realize that it probably looks as bad as it does because of improper prep. That being said…time to redo it. We originally used Cabots Australian Timber oil and are leaning towards using a solid stain this time. I started power washing and there’s still a lot of stain left behind..do I need to strip, use a cleaner, sand or just finish power washing and proceed with solid stain? Pictures sent..1st pic is pre power wash!
Thanks
Strip off what you can, brighten and then cover the intact stain with a new solid stain is okay: https://www.deckstainhelp.com/what-are-the-best-solid-color-deck-stains/
Purchased a home with a HUGE wraparound deck ( 30×18, 10×21, 4×21) and would love to replace- but am hoping we can squeeze a few more years out of this one. Currently, the largest deck has multiple layers ( atleast 3) of badly cracking, Peeling, lifting Sun Proof Acrylic latex solid stain from previous owners. We have tried pressure washing, scraping using CitriStrip- and nothing will penetrate to bare wood. Unsure what to do. Suggestions?
Not much you can do but sand off the loose/peeling stain and then cover the rest with a new solid stain:

Will Restore-A-Deck stain stripper work on old film-firming stain and remove completely? Thank you.
Depends on the brand and type of stain? Pictures would help as well.
