TWP with Wet on Wet Application Tips
TWP Stains are to be applied “Wet on Wet” when the wood is absorbent enough to handle more than 1 coat of the stain. This is typically for wood and decking that is older than 12 months and has been exposed to the elements. Applying the TWP “wet on wet” is similar to applying 1.5 coats of stain. The second coat covers twice as much square footage as the first coat.
Applying TWP “wet on wet” is very easy and not complicated once you understand the simple steps.
How To Apply TWP Wood Stains “Wet On Wet” to a Deck:
- Apply the TWP to the verticals first. This would include the railings, benches, and any vertical walls.
- Lightly apply one coat of stain to the horizontal flooring. Apply to the entire floor surface. If your deck has multiple levels, do one level at a time before moving to the next level.
- Wearing shoes that are disposable, walk back onto the “wet” stain and reapply another coat to the “tops” of and railings, walls, and benches. You may walk on your first coat of stain 10 minutes after finishing.
- Apply your second coat of stain to the horizontal flooring. Take care to not step in or leave footprints in your second coat!
- Finish stairs last, repeating the above steps.
TWP Staining Tips
- Do not apply 2 coats of stain to new wood or decking or to recently sanded wood that was sanded finer than 60-80 grit as the TWP stain may not be able to fully absorb into the wood.
- In most cases, a second coat only needs to be applied to horizontals as the verticals will last twice as long.
- Apply your second coat of stain within 10-60 minutes of the first coat.
- Watching for puddling on the floor. This usually happens under railings and benches.
- Wear shoes and clothes that are disposable. Do not wear shoes that have black soft rubber soles. The TWP can “soften” these soles, leaving black residue marks on your deck if you step in the stain.
- TWP Wood Stains can be applied with a stain pad, brush, roller, or sprayer.

I have 230 linear feet of 6′ high fence where the posts are pressure treated wood and the pickets are cedar. It has been 6 months since installation – I’m in Texas so they get a lot of sun. Bottom half of it gets water from the sprinkler system. At the moment, it has greyed a little and has water marks. The calculator shows I’ll need about 14 gallons of TWP 1500. Could you confirm the calculation and recommend the best way to go about staining the fence?
If doing both sides of a fence, you will have over 2500 sq feet to stain. With 2 coats, you will need 20-25 gallons. You can apply with a brush, sprayer, or stain pad.
You mention not to wear black rubber soled shoes. How about crocs? Is the warning for rubber only? I would image most soles are some sort of synthetic material these days.
Not sure about crocs. Probably okay.
Can I wear protective covering on my shoes when applying a 2nd coat of TWP 1501 or would the stain be sticky such that the shoe covers would stick to it?
No need to cover your shoes but you can. Just wear some shoes you do not care about and walk on the first coat.
Unfortunately, all my shoes have black bottoms.
What moisture meter reading should I have to apply twp 1500? We’ve started to get morning dew that has left the deck moist in morning.
15% or less.
Can I apply first coat to a deck that has not completely dried after cleaning
No.
We are about to stain a fence installed last spring and have 2 questions. Do you recommend the wet-on-wet method or is it just as good to let it dry between coats? Also, we have 17 fence panels that have 50 square feet on each side (totaling 1700 square feet of fence to stain.) For the two coats, how many gallons do we need to order?
Has to be wet on wet. About 15 gallons for two coats.

I had my deck pressure washed and re-stained with TWP 1500 after 2 years. He cleaned it well. 2 years ago I used the same TWP stain. It looks fantastic. I was just a little concerned as it appears he applied the floor boards a little heavy. They are NOT puddled but still real shiny whereas the rails are drying well . It has been about 20 hours since the floor boards were stained. The weather has been 57 in the am and 69 after 12pm. Tonight it will get down to 43 degrees then a high of 73 and in the 70’s the next few days with no rain for several days. Should I just give it another day or two to see it it dries before assuming it was applied to heavy on the floor?
Yes, let it continue to cure and dry.
Thank You!!!!!
I had some painters who painted my last house apply the TWP to my bare cedar deck. It had been somewhat weathered over the winter and I had applied a mold killer and then a stain remover, so it was quite clean. They only applied one coat, and it dried quickly because the weather was in the 80’s. I noticed some patches here and there where they must have left too much material or inadvertently painted over dried material that remains shiny. The whole deck is now thoroughly dry, including the shiny patches. They did not do wet on wet, which was probably good as the stain was drying so quickly. We were thinking of applying a second coat this coming weekend, but I am concerned that might only create a “skin” rather than soaking into the wood, which for this product, is a failure condition, as I understand it. The railings, on the other hand, are rough cut, so probably could absorb a second coat. How do you recommend we proceed at this point regarding the shiny patches and a second coat; and also when and how do you recommend we treat the deck going forward in the following seasons, given the conditions I mentioned.?
Post some pics.
See attached photos
We would suggest stripping and brightening in the Spring so it is all even.
So new decking is ok to be left not stained into winter? Deck has been up for about a month. I noticed my flower pots leaving stains on new decking as planned to sand those off before my deck cleaner/ brightener and then 1500 stain. If we wait to stain then those pots will do even more damage. I will put trays under those pots now in hopes less wet / stain happens. If I sand the whole deck now will that take off that waxy layer and then allow me to stain now?
Yes, you will need to wait until after Winter. The stains from the flower pots will continue to happen if stained or unstained so best fix the issue (the pots) if you want to avoid this in the future.
You cannot stain it now.
I sanded whole deck with 60-80 grit paper , did the cleaner and brightener , so once 48 hrs dry ok to stain it now? Rain forecast before that 48 hrs is done- do I need to just wait for 48 hrs after rain to apply stain? Hope I don’t have to redo cleaner and brightener!
Wait 48 hours after prep or rain to stain. No need to redo prep if it rains.
I have 3 gal in a a 5 gal pal and 2 gal unopened . The weather is starting 30s in the am and 50s in the pm. How long will the stain keep if I wait until next year?
https://twpstainhelp.com/shelf-life-of-twp/
So after the second coat of wet on wet procedure, how long of a wait before we take off excess stain?
30-60 minutes.
I waited a year to stain my pressure treated, covered porch. The contractor at that time used a single, thin coat of TWP. That faded and the outer edges impacted by the elements were more affected then the inner part of the porch. There was no shine what so ever.
Now, a little over a year later a different contractor stained with TWP in the same color. He did one coat with a brush. Let that dry for a few days. Then came back and did a second coat. The porch is shiny like it was polyurethaned. Is this normal? I didn’t want it shiny at all. However roughly 3′ of the 8′ board is not shiny and it’s where the water hits it along the outside edge.
They are talking about a third coat once this dries. Is this a good idea? He also suggested we poly over it to even out the appearance & texture. I definitely don’t wish to do that. Please help!
No. Not supposed to be shiny. They over applied. Do not add more. Never apply a poly over a deck stain.
Your contractor is inexperienced with out stains.
What do you advise we do from here?
Do you have pics you can add in the comments?
Application for thirsty deck. Have a 18yr old neglected pine deck last stained 10yrs ago with water base. Replaced rotten boards 1.5 yrs ago…approx 1/4 of deck. Pressure washed and sanded deck with 36 grit belt sander with grain. Will be using Restore a deck stripper brightener. Wood is very thirsty and expands a good bit when it rains. Deck is now 2/3 covered and screened in not getting rain or sun. Humidity has dropped in this area to about 60%.
1. How long should I wait after the last rinse to apply stain? Weather permitting, I plan to stain a week after strip/brighten. Should I wait longer to let the wood dry out more?
2. Because it is a large deck, can I break up the staining process over 2 weekends? Should I be concerned that the moisture content will vary enough to create 2 different shades?
3. What is the best way to apply? Brush then brush, brush then pad? Pad/pad? Concerned thirsty wood may need heavier 2nd coat but don’t want to overapply.
Thanks
1. 48 Hours.
2. Stain all at once unless you have a clear dividing line to break it up.
3. Brushes and stain pads. Use either or, you do not need both for wet on wet application.
new trellis and arbor, out of redwood. It has been in the 100 degree sun now for about a month plus and sprinkled water to see if it beads….it doesnt. is it ready to be stained? i want to have it stained b4 cold weather and winter gets here. any advice? i want to go for dark colors closer to black semi solid
Cannot stain it yet. See here: https://twpstainhelp.com/prepping-new-wood-for-twp-stains/
Prep and stain in Spring. The Winter will not harm it.
7 year old deck. Treated pine. Waited recommended time before Ist staining. Used Behr castle gray semi-transparent which didn’t last a year and Behr solid for 2 subsequent stainings. Followed instructions re: temperature, etc. Not a good outcome. Last summer’s coat was peeling before Fall. Tired of sanding and reworking so often. Indiana weather. Should I use the Gemini prep kit before applying TWP semi-solid? And do I need to sand again before cleaning? Hopefully TWP will last longer on horizontal surfaces and allow me to get a few years in between stains.
Please reply back with some pics for prep. The Behr has to fully come off and many times that means power sanding.
Pics of deck
No pics.
Here they are
You will have to power snd this off. Behr lies about their opacity and what you have is an opaque solid stain and strippers will not remove it fully. Once fully removed with your prep, you can use the TWP 1500 for Indiana.
You recommend TWP 1500 for Indiana and not the semi-sold? My deck is weather but still has some Sherwin Williams semi-transparent left on it after three years.
The TWP semi-solid is not allowed in IN. You have to fully remove the SW stain first whenever you are switching brands of stain.
How many coats would you recommend? My deck is 20 yrs old
Two coats wet on wet.
Is there small samples of the 1515 honey tone to test for color so we can tell if we like it
https://www.twpstain.com/stain-samples
Can I 2nd coat stain the next day
No, wet on wet is correct.
Cans say wash with bleach. Is this true?
How long leave on deck . I have stripped the deck
Use the Gemini Restore Kit for the best prep.
We have cedar siding on our house. It is rough and absorbs the stain well, the siding has been up for 12+ months. We applied the 100 series last year. We sided the house ourselves so stained sections as we finished. We used the wet on wet application on the previous sides. Two sections of the house did not get stained last year because of weather. I used the cleaning and brightening products on your website for the unstained siding. We want to apply 4 applications to the siding that has no stain so it has the same amount as all the other sides we did last year (2 coats last year and 2 coats this year). Can we apply 2 coats wet on wet on the unstained portion; if the wood is thirsty and soaks it up and it feels “dry” to the touch can we go back and do another 2 coats wet on wet or do we need to wait a season or several days?
No. Never apply more than 2 coats. You can light clean and apply more in a year or two if needed.
I am trying to get this terrible textured paint off my deck. I’m using a 40 grit to chip away at it. I want to use the TWP semi-solid (a darker color). Should I still clean the deck after I have sanded it? And after I’m done, should I only use one coat since I used a 40 grit to get down to a clean board?
Sand it all off and then clean and brighten with the Gemini Restore Kit for final prep. One coat of the TWP semi-solid.
I sanded my deck with 80 grit will the stain absorb
Use this for final prep and then stain: https://www.twpstain.com/gemini-s-restore-a-deck-cleaner-and-brightener-kit
I have 1000 sf of deck, one level wraparound. two basic questions:
1) it’s taking me 3 years to get this deck to this point of prepping. It’s been stripped/pressure washed, sanded with rental sander which still left old finish. (I’m a 70 yr old lady, so the sander ran me around the deck.). In 2021, I hired an outfit that stripped, cleaned and spot sanded (supposedly). Still had old Behr finish so I fired them as they said it was good to stain despite my protests. Finally, this year, I got 2 guys to hand sand posts, bench and deck.50 hrs of labor later, it looks good, but even after all of that, there is still grey on some boards’ wood grain. At this point, the boards are absolutely smooth to touch, but I’m concerned about jumping to next stages of brightening and staining and throwing away all of the work done so far.
I’ve read that as long as water doesn’t bead up on grey areas in graining, it’s porous enough to accept stain. Done that test and water soaks right in. I now need to use brightener, before I stain, correct? If there is still some grey in grain, can I safely proceed?
2) Now weather is not cooperating. I can find 2 days of dry after staining in next two weeks, but getting five days total (2 before, 1 for staining, 2 after to dry) will be rough. It may be 1 1/2 days after stain before next round of overnight showers. Is 36+ hrs enough with temps in upper 70s, humidity around 60, and partly sunny?
I so want this to be over . . . 😟
1. Clean and brighen for best results. You want the wood porous, not smooth.
2. It can rain 24 hours after staining.
How long before I can put furniture back on the deck.
24-48 hours or when fully dry.
I applied 1500 yesterday but even no rain in forecast for next four days my luck it drizzled after one hour I finished I can still see water beads and some sections looks on even what would you suggest I should do
After the rainwater dries off see if any water spots or not in the stain. If so, send pictures. If not, then no worries.
it is cedar clean and sanded like new
Only one coat on sanded wood.
would second coat of pecan 1500 get darker
I have a brand new rough sawn fence. Do I need to wait for it to weather before applying TWP 1500 clear or can i apply right away? Do I need 1 coat or 2 on a fence?
You can stain rough sawn wood right away. 2 coats wet on wet. Use a tinted color if you want to prevent UV graying.
What pressure do you spray tip clear pro series
I have a 5 Gallon Bucket of Cedar Semi-transparent Deck stain from last summer. I used about 4 gallons last year but when I opened it this year to stain another deck, about a 1 Inch thick film developed on the top of the stain. I punctured the film and used some of the stain below on some vertical rails but when I went to use it on the deck itself, the solidified stain would have made spraying impossible and using a roller problematical. is there some method such as sunlight or minimal heat to melt it. if not if I strain it out will the remaining liquid still be usable or did the solidified material contain some of the necessary chemicals for a horizontal deck stain with a long duration?
It has gone bad and cannot be fixed.
I used the product without reading instructions and now it is dried but shiny. What can I do to fix it?
https://twpstainhelp.com/twp-stain-is-spotty-or-shiny/
Cleaned deck 2 weeks ago. But now it’s graying already. Do I need to clean again before applying 100 pecan. I’m only home 2 days a week. Thanks
Yes.
I’m planning to apply TWP 1500 to an outdoor table that I’m making – the wood is deodora cedar. I’ve sanded the wood to 240-grit, but I read above that anything higher than 60-80 grit and the product may not fully absorb. I’m hoping to keep the 240-grit sanding that I’ve completed, as I’d like a smoother surface than 60-80 grit for furniture. Is there an application method that is recommended for furniture sanded to a smoother grit?
You cannot sand this fine and you cannot stain need wood right away. The stain will not soak in properly. See for tips: https://twpstainhelp.com/prepping-new-wood-for-twp-stains/
Sorry if this is a repeat question but I couldn’t find it in the 100 FAQ’s I read. I thought somewhere on this site I read that you shouldn’t apply stain if rain is expected during the next “few days”. How long do you recommend? Should we hold off if rain is expected within the next 24, 36, or 48 hours? We did the restore-a-deck stripper & brightner and are ready to apply TWP 1500.
Thank you!
TWP can take a rain typically in 8-24 hours.
Can I add a second coat a week after the first coat was applied?
It may not take and dry correctly as TWP should be applied wet on wet if doing a second coat. Do a test board and let it dry for a couple of days. If not sticky or tacky then your wood can take another coat.
I plan to use 1500 California Redwood on our log home. Our logs are 130 years old and are cypress. 30 years ago we put a clear coat of TWP on the logs. We have not put anything else on the logs since. The logs were grey and recently I power washed the logs and now they are a pretty honey brown. I did a sample on the logs in an area under the porch. The honey tone did the best job of not making the logs dark but I was told that honey tone did not offer much UV protection. I decided to go with California Redwood because I was told it offered more UV protection and it did not darken the logs too much as compared to Redwood and Cedar. If I just power wash the logs and then wait 48 hours and then apply the stain will that be okay or do I need to do additional cleaning products?
That will be fine.
My screened porch is 12 x 16′ on a south facing, fairly shady side of the house; it gets some east/west sun in Wisconsin. The porch is about 15 years old and is now grey. Do you recommend that I use the 100 or 1,500 series and what combination of brightener? Do I need to strip it? Would you recommend power washing first? Food crumbs and dirt collect in the crevices between the boards. How much product do I need?
Please reply back with some pics so we can help with prep.
I’m an old lady. I can’t possibly prep and stain an 11 x 25 deck on the same day. Can I prep one day and stain a dry deck the next day? Also I cannot possibly remove my large Weber grill (on wheels) from the deck. So can I stain (with semi solid) half on one day, then move the grill to the stained part the next day and finish the rest?
TWP stains cannot be stained the same day as prep. You need to let the wood dry for 48 hours after prep before staining.
any suggestions on that grill on wheels?
You can do half at a time. Make sure you have a clear distinct start and stop point.
Does this wet on wet application is necessary also for TWP 200? I have a 5 year old deck that will get stripped and brightened before staining.
If doing two coats, then yes.
I have a new 1500 square foot pool deck with AC2 boards. Do I put one or two coats on. How many square feet should the average new deck absorb on first application.
See here about new wood. https://twpstainhelp.com/prepping-new-wood-for-twp-stains/
Having a hard time finding this answer. i need a second coat in some areas, mainly around knots that seem to have soaked in quickly. I understand the wet on wet approach which i did but probably not enough – so my question is why can i not hit a second light coat over some areas where i can wipe off & blend it together ?
Knots will dry lighter in color due to the density of the wood there and that is normal. We would not suggest spot touching them up. It will probably not blend and they will still be lighter in color when it dries.
We have a very large single level deck. It will take us longer than 40 minutes to finish it before we can get back to apply the second coat. How much time can expire before applying the second coat? We are using the 1500 series.
40-60 minutes is okay.
Can you apply oil-based poly over TWP 1500 Series stain?
No, you can never apply a sealer or poly coating over the TWP.
I live in Ohio under a canopy of trees and next to an ever flowing creek year round. What is the best product 100 or 1500?
For Ohio, you need the 1500 Series: https://www.twpstain.com/twp-1500-series
Is that because of the moisture and will two coats last 3 years? Thanks.
No, it is because of VOC laws in Ohio. 2-3 years is the norm for a horizontal deck. Longer on vertical wood.
I have a 12 x 16 deck with railing. It will take several days due to weather to complete. How is it possible to do wet on wet,unless i do in sections. Also how to apply a continous stroke on a 12 ft board, more product at beginnng of stroke,less at end of stroke? Thank you
A 12×16 deck should not take more than a couple of hours to stain. If you want to break it up then do any railings first. The flooring would take less then 30 minutes to coat for each coat.
Im using brush, but open to better suggestion. Took me 3 hrs to brush a 6ft section of railing would it be better to spray or roll on horizontal deck section thank you
Use a stain pad or sprayer is fine. See this article for some help on staining faster: https://www.deckstainhelp.com/how-to-stain-a-deck-fast/
How long after using the brighter should you wait to apply stain 1500? Also my deck is 2 yrs old and never stained or painted how many coats of stain, I will be sanding it with 60 or 80 grit paper.
Wait 48 hours after prep to stain. 2 coats applied wet on wet.
Can TWP be applied in direct sunlight?
Yes but you do have to watch out for flash drying. Move quickly and always keep a wet edge while applying.
Rough cut is very absorbent so two coats wet on wet are typically needed. Do on all.
Our contractor must have had black shoes because after staining this morning I got home and we have lots of footprints on the newly stained deck! How can I get them off? (BTW, they said the product was great!)
Many thanks!
Sorry to tell you this but the only way to fix is to strip it down and start over.
Can application be sprayed for both the 1st and 2nd coat?
Best to spray first coat and then back brush your second coat. This ensures an even application without puddling.
