Best Deck Prep? Clean, Strip, or Sand the Deck? 4.8/5 (77)

This post was updated on June 25, 2024

Hi, I am Scott Paul, a leading exterior restoration contractor and business owner with over 30 years of experience in exterior deck cleaning and stripping prep. My wood prepping help tips are based on my history as a wood and deck restoration contractor and actual hands-on testing. See here for more info about me.

How to Prep a Deck 2024

See my Deck Stain Facts section, which includes over 150 simple Q&A articles that answer all your questions about deck staining, cleaning, and prep.

This has become one of my most popular articles on how to prep your wood deck before applying a wood deck stain. In it, I will help consumers find the best way to prep their deck for an application or reapplication of a deck stain or deck coating. Not all scenarios are the same, and this article, with your input and pictures, will help determine the proper way for you to prep.

Best Deck Prep? Clean, Strip, or Sand the Deck?

Best Deck Prep? Clean, Strip, or Sand the Deck?

Clean, Strip, or Sand the Deck?

This is the 2nd most popular question deck owners have on this website, with the first being What is the Best Deck Stain? Prepping your Deck is the most critical aspect of the restoration process and will determine your final appearance and the stain’s longevity. Not prepping correctly can lead to premature stain failure and poor appearance results.

My 3 Easy Pro Steps to Decking Prep

  1. Determine your deck’s current condition.
  2. Understanding the 3 Main Ways to Prep a Deck.
  3. Unsure how to Prep? Ask me for Help!

1. Determine Deck Condition

How to best prep your Deck could vary on many scenarios:

  • Is the wood new or old?
  • Does it have a previous coating on the wood?
  • Are you re-coating with the same brand and colors as last time?
  • When was the last time it was stained?
  • What type of stain was it coated with before?

A better way to approach the deck prepping question is to ask, “What is the best deck prep for my deck due to its current condition and age?”

2. The three main ways to prep a deck are:

  • Deck Cleaning followed by Wood Brightening
  • Deck Stripping followed by Wood Brightening
  • Power Sanding
  • Or a combination of the above

Wood and Deck Cleaning Prep

Wood and deck cleaners are designed to clean and prep the wood before applying wood stain. Deck cleaners are to remove grime and dirt, oxidation (graying), mold, algae, and, in some cases, deteriorated stains that have failed. However, deck cleaners typically do not remove old deck stains or paints. Deck cleaners will “loosen” the dirt and grime so you can scrub or lightly pressure wash the wood without damage. Most deck cleaners will slightly darken or raise the pH of the wood, so following with a deck brightener is needed. See here for more Deck Cleaning tips.

My Pro Tip: Do not use bleach-based deck cleaners. They are bad for the doo fibers and your environment. Examples include Olympic Deck Cleaner, 30 Seconds Deck Cleaner, and Behr Deck Cleaners. See Deck Cleaner Reviews.

Wood and Deck Stripping Prep

Deck stain strippers are designed to remove deck coatings like clear sealers, transparent stains, semi-transparent stains, and some semi-solid stains. They are not designed to remove solid color opaque stains or paints. In addition, coatings that have a shine like a varnish cannot be stripped with a deck stain stripper. Deck strippers work on your old stain by softening the old coating to be heavily scrubbed or pressure washed off. For a stripper to be effective, it needs to penetrate the coating and soften the bond between the coating and the wood. If it cannot penetrate the coating, it will not work. Deck stain stripper will significantly darken the wood, so a wood brightener is necessary to lighten the wood and restore the pH balance. See Deck Stripper Reviews. See here for more Deck Stripping tips.

My Pro Tip: If you have a Solid Stain, Deck Paint, or Varnish on your deck, you could try a Paint Stripper like the RAD PaintStrip to remove the coating.

Sanding a Wood Deck For Prep

I am not a fan of sanding a deck, but in some cases, it is needed as stripping may not fully remove the old coatings. If you need to sand off a solid stain or paint, it is best to start with 40—or 60-grit sandpaper, which is the best option for stripping old finishes. Never sand finer than 80 grit paper. Sanding finer than 80 grit may close the pores and prevent stains from penetrating. See here for more Deck Sanding tips.

My Pro Tip: You can lightly spot hand sand to remove splinters or raised wood fibers. If you have furring of the wood grain, see this article. Deck Furring after Prep.

3. What is the best way to prep my Deck?

I will ask a series of questions. Based on your answers, I can help you determine the best way to prep your Deck before applying a deck stain.

  1. New Wood or Older Wood?
  2. Does the Deck have a Current Coating?
  3. Are you Switching Brands of Deck Stain or Applying a Maintenance Coat of the same Brand and Color?
  4. Deck Stain Brand Previously Used? Enter “unknown” if you do not know.
  5. What is the Current Deck Stain Type? Oil-based or Water-Based? Clear, Transparent, Semi-Transparent, Semi-Solid, or Solid Stain?
  6. Mold or Mildew Issues?
  7. Reason for Previous Stain Failure?
  8. You Must Include Picture(s) of the Current Condition.

Thank you for your reply. We ordered the RAD stripper with both additives, the RAD brightener and 3 gallons of the RAD solid stain. Got all my supplies, planning on starting bright and early to get it all done tomorrow. As I was clearing everything off the deck tonight, I realized I’m an idiot. The siding doesn’t seem like real wood. It seems like a composite of some sort? I realize I should know what it is but I don’t. My question is can you tell what it is from the pictures? Do I treat it like the rest of the wood, strip it, brighten it and then stain it? Or do I need to protect it somehow?

Ok, I’m finally done. And it looks fabulous if I do say so myself! Anyone that has any hesitation about purchasing the RAD products – do it. If I can use them, anyone can. It was so simple to do, and it came out great. I tried to take pictures after each step, but they don’t do it justice. First 2 pictures are the before, with the Behr product. 3rd is after stripping. I can only put 4 pics per post, so end results in next comment.

My results after using the Restore a Deck stripper, brightener, and solid stain in cypress. This stuff is amazing. I’m a 45 year old vet tech who’s pretty lazy. If I can use these products, anyone can. See previous comment for other pictures. First 2 pictures are after brightener. That stuff is amazing. Final 2 pics are after applying 2 coats of stain with a roller. At 10pm at night. There are a few spots where it’s a little lighter than the rest, and I was wanting to go back and get in between the boards. Can I touch up the light spots and do in between boards or did I miss my opportunity?
Thank you again for all your help. You saved my mom $1800, and made me the hero!

Bought the house three years ago and haven’t done anything to it. Looks horizontal boards haven’t been stained in a long time. The vertical boards look like they were stained again, but at least 5 years ago.
I want to do the whole thing in a semi-transparent.
Do I need to strip this? Or can I just clean, brighten, re-stain?

We had a contractor to prep the deck before a painting company is to come put a solid stain on. He stripped and did a rigorous power washing along with sanding some areas and even scrapping but could not get all the paint off. We are going with a darker solid stain on the flooring but what would you recommend for additional prepping. I think it needs a 60-80 grit sanding to smooth things out since the contractor has left it a bit of a mess. Thanks!

Refinishing (again) a 20+ year old cedar deck. It has some rotted sections on the ends but still stable enough to get another few years out of it. Some pretty significant deep weathering, so I’m planning to sand it down to clear and use an oil stain. (Cabot is fairly available, TWP is harder to find locally.) Hoping the sanding precludes the need to use the chemical stripper. Thoughts on that?

And my big question is if I sand it down, do I need to weather it and use brightener before staining?

New Wood or Older Wood?

20+ year old cedar

Does the Deck have a Current Coating?

Mostly worn off, but some remaining in areas protected by furniture.

Are you Switching Brands of Deck Stain or Applying a Maintenance Coat of the same Brand and Color?

Planning to switch to a penetrating oil since I’ve had zero luck with any of the water-based stains I’ve tried.

Deck Stain Brand Previously Used?

Not sure what all I’ve tried, but I know I’ve used Flood and I think the latest was Behr. Have used stripper and brightener every refinishing.

What is the Current Deck Stain Type? Oil-based or Water-Based? Clear, Transparent, Semi-Transparent, Semi-Solid, or Solid Stain?

Water-based, semi-transparent.

Mold or Mildew Issues?

Mold, mildew, lichen, yep

Reason for Previous Stain Failure?

Wisconsin. No matter what I’ve used, it starts peeling up after the first winter.

You can see in the pic that I did start sanding. If it’s a bad approach, I can live with that one course of treads being different, but the deep grain grooves seem to trap dirt and mold.

Installed new red cedar decking last fall. I used the RAD cleaner and brightner yesterday. This morning the deck has white blotches aroung the knots and some on the boards. I misread the brightner instructions and did the entire decking at one time rather than a litlle at a time. What can I do to resolve this? Thanks.

After my post I used clean water and a stiff brush to go over a small section. There is this ‘gunk’ that comes up. I can wipe it up with a sponge. Is there value in removing this? Which choice (remove ‘oxidation’ or not) will leave me with the best, most consistent look with my A/C semi-transparent stain?

Marty

Did a ‘good’ power wash again(no RAD, just water) and it did indeed remove all the gunk. There is a very fine line when power washing.. After all this should I expect to have good/appropriate absorption of the stain in the cedar?

I’ve got a 30 yr old deck in fair condition. I hired a guy to work on it 3 years ago who put a Sherman Williams solid paint like stain on it.
It’s peeling off in pieces but some areas are still stuck on.
I plan on power washing it lightly to blow all of the loose stuff off and then use stripper on the parts that didn’t come off.
I’m too old and arthritic to do this again and want to go back to a clear water repellent sealer type again

Is that possible?

Hello! It’s been about 4/5 years since we’ve bought our house and our deck is certainly ready to be freshly stained/painted, and being that this is our first time doing this solo, I was hoping for some advice. We were thinking about going with a solid stain to help cover some of the imperfections in the wood (unless you think otherwise). We’re trying to determine if a simple clean and application of solid stain will do the trick? Or, if a complete strip is required:

  1. New Wood or Older Wood?
  2. Older
  3. Does the Deck have a Current Coating?
  4. Yes, it appears to be a solid
  5. Are you Switching Brands of Deck Stain or Applying a Maintenance Coat of the same Brand and Color?
  6. We are switching brands as we do not know what the prior homeowner used
  7. Deck Stain Brand Previously Used? Enter “unknown” if you do not know.
  8. Unknown
  9. What is the Current Deck Stain Type? Oil-based or Water-Based? Clear, Transparent, Semi-Transparent, Semi-Solid, or Solid Stain?
  10. It appears to be a solid
  11. Mold or Mildew Issues?
  12. Some mildew as the deck is semi shaded from a tree
  13. Reason for Previous Stain Failure?
  14. Lack of maintenance

Thanks for the quick reply! And just so I understand, using the stripping agent on all parts of the deck, even on the privacy fence area that still had a solid coat, is necessary before applying the new solid? Or, can you simply stain right over any existing solid that is in good condition?

My husband over stained our deck last year. So much stain that it transfers to clothing and feet etc. He used stripper this year which resulted in uneven color, spots, and furry parts of the wood. I read, after we noticed the furry wood, if he had used brightener after stripping he might have avoided the furry wood, not sure if that’s accurate or not but either way he did not. So now we are trying to figure out what to do. We still have stain transferring onto feet and clothing. Do we use stripper and brightener? Do we sand? All of the above? What kind of stain could we apply to not risk any transfer? We also need it durable for kids and dogs. The deck was built in 2019 so it’s newer.

Hi Scott,
I sure could use your expertise! My deck has some serious issues due to mold. Most areas get very little sun so rain and snow have done a number on the horizontal surfaces. I believe it is all pressure treated wood. The railings appear to be in very good shape. The deck is 30+ years old and currently has a semi-transparent water based stain. I want to change to a different brand of a solid water based stain.
I need guidance on the best way to prep for staining. Not sure if horizontal surfaces need stripping or sanding. Can I just clean the vertical surfaces as they are in good shape?
I would also appreciate tips on how to try and avoid mildew in the future, if that is even possible.

Hi Scott,

My redwood fence is 7 years old and it’s time for a little TLC. A couple sprinklers were hitting the fence and washed the boards out. I power washed the fence but the lighter areas from the sprinklers are still there. It previously had a transparent stain of SuperDeck, oil based. I am planning to stain it with TWP 1502. My thought is that a semi transparent stain will help hide the discoloration. Is that the correct approach? After power washing, the fence came out clean with no mold or mildew issues. I thought a brightener will help even out the boards as well. Do I need a stripper of cleaner prior to the brightener? I have a lot of fence. Realistically how much coverage will I get with 5 gallons.

Thanks for the help,
Chris

I purchased the Stripper and Brighter for a older Cedar Deck, and unfortunately I’m having a problem removing mold from my deck. I’m going to try again today, but notice that there is something else I probably should have purchased to go alone with the stripper. 3 of the boards look brand new which of course is at the edge but the others I’m having the worst time getting the algae and mold off the boards. I feel that maybe I should have cleaned them first. So before I continue to try and clean my deck can you give me some advice. I tried to ask before I purchased the products but of course there was no responds

Repost due to corrupted link.
Scot I need your expertise! I don’t know where to start with this deck. It’s around 10 to 12 years old. I hired a professional painter to apply a semigloss. He chose SuperDeck. It appeared solid after it dried. 6 months later it started to peel. It is now mostly gone from the weather. The wood has some cracking and pitting/grooves. The deck is high up on my second story. Full Sun on most of deck with mild freezing winters with light snow sometimes and hot humid Carolina summers. The bottom of the boards look dirty/moldy but not as worn. Should I replace the worse boards then prep and stain. Should I flip all the boards and replace the worse ones then stain? What product/transparency/color should I be looking at? I look forward to you recommendations.

Thanks for this service! I’ve tried for 5 years to figure out a correct stain.
1. Wood is 5 years old
2. Yes
3. Switching brands
4. Cabot
5. Semi solid
6. Slight mold around the base of the beams
7. Dirt (from 3 boys and a dog) just seems to stick to it. I have tried literally mopping it and it doesn’t help.

You can see the color difference in the pictures from the floor and the beams. The beams show what it looked like when first stained last summer. The floor shows the color difference because of the dirt and dust. I also need something that will clean this off so I can start all over. For stain purposes I was looking into the DEFY extreme stain that you recommended.
Thank you!

Hi Paul, so happy to find your forum….been looking for help for a long while.
Would love to restore luster and also get rid of the black coloring that is mostly evident on bench sides.
Meranti deck (pre-coated), approx 13 yrs old
Have done light sanding about every 5 yrs, regular (annual or every 2 yrs) cleaning followed by 2 coats of Penofin Brazilian Rosewood Oil (transparent) as recommended by lumber vendor that we bought deck material from.
Last coat was 2 yrs ago.
Photos show current color/consist ion as well as one area that gets limited exposure (to show original color).

Hi Scott. Thanks for the info, as the more I read on various sites, the more confused I get due to conflicting info.

  1. Mixed–deck older, railing 8 months old (shortly before move-in). Assuming this implies using a semi-solid or solid stain?
  2. Not sure. Corner under overhang more reddish, so would guess yes?
  3. Switching brands
  4. Unknown
  5. Unknown
  6. Assuming mold/mildew, because part near grill/bushes is a bit greenish
  7. Old

Confused as to whether to use stripper, sand, or just clean+brighten. If you advise to strip or sand, please let me know whether to:

  1. clean, then strip/sand, then clean again, then brighten?
  2. clean, then strip/sand, then brighten?
  3. strip/sand, then clean+brighten?
  4. some other combo?

Thanks so much!

Hi Scott,
working on a Alaskan cedar deck that is 7 months old. We put a light penetrating sealer on it and it mostly wore off but not on railings. We have stripped twice sanded entire deck and what we can reach in railings with orbital sander and power washed. Deck looks okay, railings not so good. Stripper and sealer look dried on wood, power washing didn’t remove the sealer. It’s a big mess. I will post photos but how can we get sealer and etc off railings? Have we over stripped, sanded and washed. Can we wet again and brighten so we can stain? Pics to follow. Thanks so much! Eliza

I have an IPE deck that hasn’t been treated in a couple of years. Areas exposed to direct (Colorado) sun have taken a bit of a beating. Last treatment with Penofin Transparent IPE after light sanding yielded great results. Best to manual or powered scrub brush to remove accumulated dirt or use a chemical cleaner? Power-washing even with powerful unit doesn’t remove all dirt. Photos attached. Thanks in advance for any guidance!

I need help prepping my deck and staining my deck and railing.

  1. New wood or older wood? Deck is 22 years old, railing is roughly 18 years old.
  2. Does the deck have a current coating? Yes deck was stained 4 years ago with Sherwin Williams Superdeck semi-trans oil based, 3573 tavern oak.
  3. Are you switching brands of deck stain or applying a maintenance coat? Want to switch brands and looking for recommendation. Looking to apply a semi-solid or maybe a solid stain to last longer.
  4. Deck stain brand previously used. Sherwin Williams Superdeck semi-trans oil based.
  5. What is the deck stain type? Oil based, semi trans.
  6. Mold or mildew. Don’t know for sure could be mildew in black locations. There is green algae on deck and railing.
  7. Reason for previous stain failure. Short life. Assume not a very good deck stain.

I need help selecting a statin for my deck and railing

  1. Which state is your deck located in? Michigan
  2. How much sun/shade does your deck get. I would say 70% sun and 30% shade. The deck is on south side of the house. There are lots of trees behind the deck that partially shade deck in the summer.
  3. What type of wood is your deck made of? Not sure. Assume pressure treated.
  4. Why/How did previous stain fail? Wore out very quickly. Assuming it was not a very good stain.
  5. What type and brand of stain did you use last time? Sherwin Williams Superdeck, oil based, semi-trans 3573 tavern oak.

Note: I am thinking about going with a semi-solid or solid stain for next coat to try and get a longer life span. It is just myself that will have to prep and stain the deck.

Thank you very much for your quick response. I have some areas where the wood is rough. Do I just sand those aeaa or should I sand the entire surface. When do I sand? Also do you have a color for the TWP Semi-solid that would most closely match by existing color? Should I stain the railing first?

Hey, I have ordered the TWP prep and stain kit for my deck. It was built in September and now, in March, I think it is ready to stain. The wood has turned from yellow to white and just waiting on some dry weather. The deck still has red chalk lines on it from construction. (Found out too late that they should have used blue or white chalk). Will the deck cleaning and brightening kit get these lines clean enough to stain with the honey colored oil based stain? Want to minimize their impact on the final look Thanks

Hello, I have an old deck that I’ve maintained with Thompson stain. Last summer I was told that the stain I have used for years, was discontinued. I began researching the best way to save my wooden deck; clean the old stain from the floor (where it’s peeling badly) and the spindles (where it has remained adhered to the wood). I am interested in

Please provide steps – we have never done this before.
Thank you!!

The dark brown deck paint applied by previous owner failed in the sun. We also had some rotten boards. We removed all boards and replaced the support in many areas and rotten boards. We flipped the remaining boards to the unpainted side. We cleaned the boards with 30 Seconds Outdoor Cleaner that we had success with on our fence. Some boards have dark edges so am planning a light sanding. I filled the knot holes with plastic wood to prevent water from pooling. The part of the deck under a roof has not failed. We don’t know what was used before. We would like to repaint the whole area so it matches. Do we need to wait 3 months for the new boards to age? What additional prep would you recommend?
