We are here to help you with your TWP exterior deck or wood restoration project for 2024!
TWP is an advanced wood preservative/protectant registered by the EPA. Performance and longevity can vary though depending on the wood type, how the wood is prepped, the age of wood, and how the TWP is applied. We want everyone who has decided to use TWP 100, 1500, or 200 Series to have the best possible results.
TWP Stain Tips and Help
When asking questions please give us some information about your wood restoration project:
- What structure is your wood? Examples would be: Deck, Wood Siding, Fence, etc
- What species is the wood? Examples: Treated Pine, Cedar, Redwood, Ipe, etc
- Is the wood new or older than 1 year?
- Has the wood been stained previously with a different brand? Please specify brand name and type of stain used: Examples: Solid stain, Semi-Transparent Stain, etc.
- Any additional info that would be useful
Once you supply us with the information, we will able to give you advice as to how to prep your wood and any needed instructions for the TWP application.
Please ask your questions in the comment area.

Hello, what’s the latest update on when 5-gallon) semi-solid will be available? Suggest you update website since it states end of August.
Thank you!
We expect it in stock today. Once it is here, we will add it back to the website.
Hi – I did the restore a deck 2 days ago and am prepping to stain my deck this afternoon but the boards still don’t feel completely dried. Is it ok to stain on slightly damp boards? We are getting a thunderstorm Friday and rain is forecasted every other day for a few days (lol), so It’s either today or wait a week for enough drying time. Thoughts?
No, it cannot be applied to damp wood. Stain tomorrow. It can take a rain on Friday.
I have 80 feet of red cedar 2”x2” baluster railing. The balusters are spaced 4” apart and are 42” high. How much TWP 100 do I need for a 2 coat wet on wet application?
Thanks!!
About 5-6 gallons for the two coats applied wet on wet.
My door is mahogany and stained with mini wax mahogany… Cypress post right next to the door.. Stained with the same… Door has almost a purple tint to it… I need the post to match door??
You would have to test samples on your wood. https://www.twpstain.com/stain-samples
What are the differences in your 100, 200, and 1500 series? Also, do you have any retail locations that we can go and view your different color options in person before making a purchase? We need a sealer and stainer for our wood deck.

We sell online only as a TWP stain dealer. You can test samples from our website: https://www.twpstain.com/stain-samples
I used TWP 1501 cedartone on my new deck after waiting the correct amount of time. We applied the stain Just several months ago. We followed the instructions and read all through the website. My deck boards are turning black and I don’t like it at all. What can be done to fix this. This stain was rather expensive and thought was going to be the right way to go but I hate the black that it is turning on my new, very expensive deck.
It could be dirt/grime from trees, mildew from pollen, etc. The stain itself does not darken in color so it is not at fault, something else is causing it. Post some pics for advice.
Here are some pics asked for
If it’s is dirt or pollen, how can I fix it. It looks terrible. I keep the deck very clean so I don’t believe it’s grime or mildew or something like that.
Pollen during season can stick to a deck while the stain is wet and can create the growth of mildew. It is had to say of this is dirt or mildew but leaning towards mildew. Using a product called Wet and Forget can clean and remove mildew. Just spray on and let it do its work over the course of a couple of weeks.
Yes Hi, is it OK to mix 1501 and 200 series together? I’m applying 1501 Cedartone and 200 Clear together 50/50 on my redwood decks to match the redwood siding on the house. I live in California and can’t get 100 series. I had the siding done with TWP about 7 years ago the contractor used the 50/50 mix of 1501 and 205 and it came out great. I don’t think I saw the “205” series on your website. Let me know. Thanks Tim (561)309 5845
No, do not mix different series togehter. He should not have done that.
When do you estimate 5 gallon buckets of semi-solid will be available to purchase? Thanks!
In the next 24-48 hours.
I am looking for a finish to protect two parts of my 1912 home – brand new white cedar shingle siding on my back porch and the bargeboards on my roofline I’d like to leave unpainted. I believe the bargeboards are cypress, but I have been patching and augmenting them with cedar as the color and woodgrain match. I would like both of these areas to retain their natural color as much as possible, without greying or fading over time. I don’t mind re-applying something every few years if necessary, but a no-sand re-application would be necessary. I was originally looking at the TWP 100 series finish, but I live in Ohio so that is not an option. Would the 1500 be an option? Thanks.
Use the TWP 1500 for Ohio. Clean and brighen with the Gemini Restore Kit every few years. Teh stain must be a tinted color for UV protection. Honeytone is the lightest color.
can I use semi solid TWP over the TWP 1500 when a maintenance coat is needed or do I have to strip the 1500 series first?
Strip and brigthen.
I have a pergola made of cedar wood. I had the wood in dry storage for 1 year before staining the wood using TWP 100 Pro Dark Oak 103 and then constructing the pergola. The pergola has now been constructed for 2 years.
The pergola receives direct sun for part of the day and some of the stain is beginning to peel off. So, it is now time to restain. What steps and products do you suggest I use to restain the pergola?
Thanks!
Use the Gemini Restore Kit while pressure washing for prep.
Thank you. One follow up question…..my pergola is constructed using Simpson Strong-Tie Outdoor Accents products such as the one found in the following link. Is the Gemini Restore Kit safe to use on these products without harming the finish?
Should be fine no way to say for certain as all coatings are made differently so do a test spot first.
An additional follow up question for you, please. After using the Gemini Restore Kit products tomorrow and waiting the 48 hour drying time, I plan to use a Chapin pump-up sprayer to apply the stain to my pergola and back brush where needed. Should a second coat be applied (while the first coat is still wet) to all surface areas or only to the horizontal surface areas while leaving the vertical surface areas with just one coat? As a reminder, my pergola was first stained two years ago with two coats of the same product.
Just wanting to be sure I am approaching this correctly before I begin. Thanks once again!
One coat for the vertical wood is enough.
Thanks. And, one more thing…..should I wet the wood before applying the Restore-A-Deck product or apply it on dry wood? Thanks!
Damp is easier.
We have a cedar deck that was stained with Behr semi-transparent water based stain in 2018. At least 50% of the stain has flaked off with the exception of the area right along the house that is more protected. We plan to stain with 101 Cedartone. From the other FAQ’s it appears we need to prep the deck with the following:
For prep, use this kit: https://www.twpstain.com/restore-a-deck-stripper-brightener-kit-detail
With both additives: https://www.twpstain.com/wood-stain-strippers/rad-stripper-additives
Thank you!
Please send some pics of the stain being stripped in the comments.
Thank you!
Your steps are correct but the issue you have is the Behr. Behr lies about its opacity and it is not a true semi-transparent stain. In fact, it looks almost 100% opaque in areas on your deck. Because of this, you may need to do some sanding to get it all off after the stripping.
We purchased and used the three products you suggested from your company and we are very pleased with the results. The Behr stain was tough to remove (like you said it would be) and it took a few applications in some areas and a lot of power washing, but we ended up with great results. Ready to stain this weekend. Thank you so much for your help!
Looks great!
The deck, which was heavily power washed, is fuzzy in spots and we are sanding it with some 60 grit sandpaper. Can we just sweep or blow the dust from sanding off prior to staining, or is there a better method?
Clean and brighten the wood after sanding.
I’m a little surprised since we just cleaned and brightened 72 hours ago and we were planning to start staining asap. We are not sanding off old stain but just smoothing out some of the imperfections in the wood caused from the process. Will the stain not adhere if we don’t clear/brighten? Thanks.
You need to open up the pores after sanding and remove any sand dust, hence the cleaner and brigtener.
How do know what series I have by looking at the can?
It says on there with the color number.
i just sanded our 1100 sq ft deck to remove old, faded, peeling solid stain. The upright floor sander didn’t quite get everything up. (Borders and small dents in wood and a few uneven surfaces). Do you think I can just use your stain remover to get the rest up? Like I said, the “solid” stain isn’t so solid due to the length of time, weather etc. much thanks.
Had to say whether a stripper will remove the rest or not. It will definitely remove some.
That’s what I was thinking too. Thank you!
Hi, you recommended TWP 300 Series for my bamboo fence but I don’t see it listed anywhere on site to purchase . Am I missing it?
We personally do not sell it.
We have a tiger deck that was installed in 2004 in Colorado mountains. we have been using Cabot timber oil semitransparent natural stain. every year we have powerwashed and just sanded again. The wood is in really good shape and has a nice grain but it always gets a tannish sheen after a year. I know tiger wood is a very hard wood. Do you think TWP would be good to apply.
You can use the TWP but you will have to fully remove all the Cabot first.
Hi, currently I have TWP 100 Dark Oak on my deck but it’s time to do a recoat and want to go with the TWP Semi Solid stain.
1) What Semi Solid color would best match my existing TWP100 Dark Oak?
2) I have approximately a gallon leftover of the TWP100 Dark Oak, can I mix/add it to the soon to be ordered 5 gal. TWP Semi Solid?
Hi.
1. There is not a matching color to the Dark Oak. Maybe Charcoal or Cabin Fever.
2. No.
Will TWP be offering a color match to their Dark Oak by spring ’23 in their Semi-Solid line?
No. It is not possible to match a semi-transparent color to a semi-solid.
hello
is California Cedar 205 still available, if not what is very close in color?
thank yo
Yes, it is: https://www.twpstain.com/wood-and-deck-stains/twp-wood-stains/twp-200-series
I’m going to be using the semi solid stain on my very very weathered deck in northern Wisconsin. My understanding is that product may be available very soon. I’d like to get a head start while waiting by prepping the deck with the Gemini kit.
How long can you leave the boards prepped before staining since we don’t know when the product will be shipped. I can stay off the deck in the meantime and maybe just rince again with water. The next issue will be the cold evenings starting. If the nights start getting too cold to stain but it’s prepped, is there something to apply to get the wood protected through the winter? Or just reprep and stain in the spring.
Stain within 2 weeks of prep. We will have the semi-solid back in stock by this weekend.
We live near Seattle Washington and are planning to stain our pressure treated wood deck. We are going to sand it and then use the Gemini Restore Kit. We are also trying to decide on which TWP product to use.
1) Is it possible to sand first and wait a few weeks until we get the product before using the Gemini Restore Kit?
2) Many people have told us to not use a semi solid stain because it will flake. Does the TWP Semi-Solid Pro-Series do this?
3) I have noticed this product is not currently in stock. If we do decide to use this product, do you know when it will be back in stock?
4) We are also considering the WP 106 Series Prairie Gray color. How is this different from the Semi Solid. I have read that it is different than the other colors in that series.
5) What is the lowest temperature recommendation for staining?
Please advise.
Thank you
1. Yes.
2. No, it does not flake as it is a penetrating stain.
3. Hopefully the end of this week.
4. Prairie Gray is semi-solid and has a kind of a “pink” hue to it.
5. 50 F.
I live in southern New Hampshire and have a 7 year old pressure treated pine deck that was stained only once with an Armstrong Clark semi transparent light oak stain. The deck is in direct full sun and has been power washed and stripped and will be brightened. Is it ok to now apply a TWP stain or best to continue use with the Armstrong Clark stain? I like your honeytone semi transparent so would you recommend the1500 series?
Try the TWP. You would need the TWP 1500 for NH.
If I can’t finish my project before the weather changes, how and where do I store the stain. Will it be usable next Spring?

Made the big mistake of applying TWP 105 (Cape Cod Gray) to our cedar deck and railing without first trying a sample! Doesn’t look good with our newly painted home. Also, the person doing the work didn’t do a good job of applying the stain evenly and only used one coat, not the wet on wet two coats. Looks terrible. When I order the Restore a Deck Stripper/brightener would it be best to also get the booster and/or additive?
Yes, use the additives. You may need to strip it a couple of times to get it all off.
Thank you. Also, should I consider a stain other than the 100 series? I live in Southern Oregon. The deck is protected with the roof of our home but gets some late day sun.
No, the 100 Series is what you would want.
A lil over 18 months ago I applied the TWP100 (5-gal-Cape Cod Gray) on PT deck. Needless to say..it’s time for its 2nd coat. Wife wasn’t a huge fan of the color. So, is it hassle free to use your new Semi-Solid Pro Series with a color she would be happier with?
For prep, use this kit: https://www.twpstain.com/restore-a-deck-stripper-brightener-kit-detail
With both additives: https://www.twpstain.com/wood-stain-strippers/rad-stripper-additives
Then you can use any of the colors you like.
From your professional level, stick with the TWP 100 or make the switch Semi-Solid Pro?
Try the semi-solid.
Can you cover TWP 100 stain with a tarp if a rain shower pops up sooner than 8hr after applying?
No, it needs airflow to cure. Do not cover it.
What is your best product for removing TWP Redwood 1500 series? We applied 2 coats of the Redwood stain 2 weeks ago to 6 of our cedar log porch posts and we do not like how red they turned out. We are thinking that the color rustic oak TWP would have been a better choice.
Use this kit: https://www.twpstain.com/restore-a-deck-stripper-brightener-kit-detail

Do you sell safe-strip stain remover?

Over the last 2 weeks I cleaned and brightened my screened porch using your products and instructions. I stained the uprights and then 2 days later (after waiting 30 hrs because of a rain storm, applied the rustic stain on the deck of the porch. It absorbed right away in most areas but there are several areas that have remained tacky for going on 3 days. We had rain again 30 hrs after staining the floor. Is it usual for areas to dry at different speeds? Is the tacky area going to be a problem? Should I take a hair dryer to it or continue to let it dry naturally? The rest seems to be beading with the application of one coat though most of it absorbed that coat so fast that I suspect if could use another coat. Do you agree? At one point can I put on a second coat?
Let it dry naturally and hopefully, it cures out evenly. Do not add more at this point. Second coats have to be applied wet on wet.
I have a cedar fence that is 8 years old and was last stained with a transparent oil-based stain 8 years ago. I planned to use the wood cleaner/ brightener kit for prep and the TWP 1500 series stain. Is it ok to apply with a roller? Is there a certain type of roller that would be best? Do you think we will need to do a wet on wet application, or will a single coat be enough? I was planning to mix in a 5:1 ratio with CA redwood:Dark Oak. Any advice on the mixing?
Strip and brighen for prep. Rollers do not work that well for applying. Use a stain pad or brush. Spraying work as well.
https://www.twpstain.com/wood-and-deck-stains/application-tools
Two coats wet on wet.
I am deciding between using a stain pad or a sprayer. Does the sprayer give as good of penetration and last for as long??
Also, if I have about 1500 feet of fence and do wet on wet, i was thinking of purchasing about 12 gallons of TWP 1500…. Does that seem like the right amount?
Yes, the sprayer gives the same results but you do have to back brush after spraying and drips and runs. Could be as much as 15 gallons. Varies based on how porous the wood is.
I used a competitors stain on my new pool deck in the spring of 2021 on wood that had seasoned over the winter (Almost 9 months). So two summers and now it is faded and water is not beading any longer. It was a major brand and I guess not applied correctly from what I can gather from your site. I did not clean or prepare the wood. So I need some help! I would like to use your 1500 Rustic but what else must I do to prepare the wood? Please tell me what to order? I live in N.E. PA and plan to do this after I close the pool in a few weeks.
Send some pics so we can properly help with prep.
Here are a few. If these don’t help I can upload more in another post. Your system limited me to two pics.
Strip and brighen for prep. Use this kit: https://www.twpstain.com/restore-a-deck-stripper-brightener-kit-detail
With both additives: https://www.twpstain.com/wood-stain-strippers/rad-stripper-additives
Do I assume (boy I dislike that word) instructions come along with the stripper and brightener? Such as, after use when to apply the new stain? I intend to do this soon so I will have September weather to deal with. Should I wait until spring? N. E. PA weather can be fickle in later September, October.
All directions are on the containers. You can do it now or Spring.
We have a deck with mahagony boards for the horizontal surface and IPE for the vertical balasters. We stained the deck 3 years ago with TWP 100 in California Redwood. It is now showing some fading on the horizontal surface and the balasters are showing some color inconsistency. We were planning to use TWP 1500 in California Redwood to recoat after cleaning and brightening. Is this a good plan? Anything we should be aware of to help this succeed?
The plan and prep are correct.
We stripped our deck last year with the restore-a-deck stripper brightener kit then did a wet on wet application of TWP 100. My question is do I need to do it again this year with the cleaner brightener or can I wait a year?
Looks good so no need to add another coat this year.
So no need for cleaner and brighter either?
Cleaner and Brightener are to only be used when you are reapplying.
Great thank you!
Another question. What do you recommend for removing spots of pine sap from this deck?
Try Mineral spirits.
Thanks. Didn’t work so I tried isopropyl alcohol and that worked well. Thanks for the great website!
Good to know.
My husband mistakenly bought Prairie Gray TWP106 stain and I returned home to find my beautiful cedar is now pink. 😩 Is there any way to layer another color over the top to soften the pink tones or what should I do? It looks really awful with the paint and stone color on our house. 🫤
No, you cannot add more to soften it. You will have to remove all and start over.
And how do I do that? 🥴
Use this kit while pressure washing: https://www.twpstain.com/restore-a-deck-stripper-brightener-kit-detail
With both stripper additives: https://www.twpstain.com/wood-stain-strippers/rad-stripper-additives
Repeat as need as removing a newly applied stain can be difficult. Brightener is last.
Are twp 100 and twp 1500 cedartone the same color? Can they be mixed together? Thanks
No, they are not the same color and you should not mix colors of different series together.
I am in Canada and am therefore limited to the 200 series. I am looking for a lighter stain but do not want to go with the clear as my deck is south facing and the clear lacks UV protection. I am very concern the cedar or gold cedar will come out with a orange or yellow finish but am having a very hard time finding photos of completed projects in the 200 series. What color would you recommend for a lighter stain that will not come out yellow or orange. Do you happen to have a better color comparison of completed work than the small color swatches posted to this page – a youtube video of dried color comparison would be fantastic for the future. Are samples available to Canada in the 200 series? Thank you!
Colors vary based on the wood type and age of the wood so there is no way to say how it will look on your wood outside of getting some samples from our site. https://www.twpstain.com/stain-samples
Just had a fence installed with new treated wood. How long should I wait to stain and seal it? What product is best for longevity and looks for years to come with low maintenance? What should I prep the surface with prior to staining and sealing?

I built a Pergola out of barn beams that are about 100 years old. Not sure on the type of wood. I took the wood from my aunts barn that blew down… I would like to protect the wood and keep the natural look. I live in WI. What should I use and how should I prep the wood.
Use the Gemini Restore Kit for prep and stain with the TWP 1500 Series.
Hello. We have a can with some left over from a previous purchase. The description on the can is ” TOTAL WOOD PRESERVATIVE”, and the sticker for the color says” TWP 116 Rustic”. However, when I looked at your website, only your 100 series, ” TOTAL WOOD PROTECTANT” has the color 116 for Rustic. The code for Rustic for series 1500, ” TOTAL WOOD PRESERVATIVE” is 1516. I need to make sure that I will buy the right stuff. Is my old leftover 100 or 1500 series? I assume it should be your 1500 series
116 means the 100 Series, not the 1500 Series.
Thanks for your quick response. But my old can has ” TOTAL WOOD PRESERVATIVE”, which should be your 1500 series. That is where I am confused and try to clarify. We didnt buy the old ones from your, but from a paint store. Could the paint store put the wrong color sticker?? We need to buy more stain from you, so I want to make sure that we wil buy the wrong stuff
No, it is not possible that you have a wrong sticker. You have the 116 Rustic in the 100 Series. The 100 Series label was changed 2 years ago.
I have a large pressure treated wood deck with TWP 200 stain. It has areas of green moss that need to be cleaned. I want to cleaned it with power washer but don’t want to harm the stain. Is there a product you recommend that I can use to spray on the deck prior to pressure washing that will safely help clean it? Also, are there any special things I need to do to safely use a pressure washer on the TWP stained wood?
Try a product called “wet and Forget”. Any harsh chemicals or too much pressure will remove or harm the TWP stain.
Restaining a pressure-treated pine deck that I previously stained three years ago with TWP. Purchased Restore-a-Deck package and TWP1500 honey oak. There’s visible green algae and dirt on portions of deck. Should I pressure-wash the surfaces to remove dirt and algae before applying the deck cleaner and then pressure-wash again before applying brightener, or is it sufficient to apply the cleaner and pressure-wash off? Also, I replaced a several step boards in June with new pressure-treated lumber. Should I wait until next year to stain those?
Apply cleaner and pressure wash off. Brightener last. See this about new wood: https://twpstainhelp.com/prepping-new-wood-for-twp-stains/
Kindly clarify optimal conditions, time of the year, and least optimal but viable conditions/time of the year that we can apply twp oil based stain to an almost 2 year old deck (pressure treated wood). TWP oil stain was applied early 2021.
Thanks!
Temps between 50-90. Time of year does not matter. The best temps would be in the 70s to 80s.
Installing a new cedar fence in idaho. Wood has been drying out since early summer in lumber yard. What do I need to do before staining with TWP100 Pecan? I am going to use a Grayco sprayer. How many gallons to cover both sides of a 200 ft in length fence? Thanks!
See here about new wood: https://twpstainhelp.com/prepping-new-wood-for-twp-stains/
Install, weather, then prep. As for amount needed, what is total sq footage for both sides?
I just had some decking replaced. I understand that I should wait about 4 -12 months before staining the wood. That being said should I wait until Spring before staining, or should I do it before Winter. If I do it before Winter the wood will have only had about 3 months at most to weather and dry out. The Winters here are cold and snowy… Thanks.
https://twpstainhelp.com/prepping-new-wood-for-twp-stains/
Do in Spring.
Gemini RAD stripper application instructions state you can apply stain 2-4 hours after brightener, on damp wood. TWP stain instructions state wood needs to dry for 48 hours. This is confusing, which is it? Thank you
RAD stripper states this when only using Restreo-A-Deck stains. For any other brand of stain (like TWP), you must wait 48 hours.
What did i do wrong? See pictures attached. The cedar deck was built 2020 it was stained in 2021 with 1501 cedar tone stain. I also cleaned it with TWP step 1 & 2 cleaner before staining. Washed off the deck with garden hose and brush no cleaner. Some of the deck stain came off. What do I need to do fix problem?
You will need to prep and restain. It is normal to have to restain new wood after the first year as well. Use the Gemini Restore Kit for prep.
I need to match new decking with the existing house. The house is about 30 years old and has been stained many times over the years. My painter said to stain the new wood with pecan…however he said I will need to mix the pecan with a darker stain to match the new wood with the old. What is a good color to add to pecan to darken it.
We need to see pics that are not .heic format. JPG, PNG, etc.
here you go
You can add Dark Oak to it but you will have to play with the ratios to see what will work for you.
I have a new, covered deck built out of treated pine. How long should I wait before applying your stain to that and which kind should I use?

I have a good condition cedar fence (rough sawn) with two coats of TWP 1530 Natural.
Last coat was two years ago. What is preferred / gentle way to clean (mostly dirt), that would not require total re-staining ?
Thank you,
M. Carney
Seattle, WA.
Lightly pressure rinse from 1-2 feet away with water only
I have a 20-year-old log home in NH with 2700 sf wall area, previously maintained with Sikkens. Am glass-blasting with 20/40 grit just enough to remove old exterior finish. I plan to apply TWP 1500. I would appreciate some pro advice !
Thanks for the help !
1. 1530 and 1501 will last the same as both are tinted and have UV protection.
2. Do not smooth or polish the surface. You want eh wood porous.
3. If it is rough when done, then no need to clean and brighten.
4. It should.
5. 2 coats wet on wet.
About 25-30 total gallons.
Thank you. Order placed.
What stain and color would you suggest for this carbonated rolled bamboo fencing. Brand new. I’d like to keep the color similar to its natural color. Thanks
You need the TWP 300 Series for bamboo.
