Best Way to Apply TWP 100 and 1500 Series Wood Decking Stains
It is best to first measure the wood surface of your staining project. Do not forget to include steps, railings and spindles if you are staining a deck and double the footage of a fence if staining both sides. On average TWP covers approximately 150-300 sq. ft. per gallon. The newer the wood the less stain it will take. Older wood is more porous and will absorb more stain.
Prior to applying any TWP stain be sure the surface is free of dirt, grime, mildew or any old coatings. Use a wood cleaner when no old failed coatings are present. If an old coating is to be removed use a wood stain stripper instead. Allow the wood to dry for 48 hours after cleaning.
The best way to apply TWP is with a brush, roller, stain pad, pump or airless sprayer. Be sure to mix the stain well prior to opening. Use protective gloves and safety glasses and cover any plants, landscaping, concrete or windows you do not want to get stain on. Apply a light coat on one or two boards at a time or in a small section. It is best to work from one end of a board to the other then move on to the next board. This will help reduce overlap marks.
If one coat soaks in fairly quickly a second coat may be applied. A second “wet on wet” coat should be applied within 30 minutes of the first coat. Be cautions of over applying TWP Stain. If excess puddles of wet stain remain after a reasonable amount of time and or not being absorbed do not allow the stain to dry. Wipe away the excess with a clean stain rag or back brush the stain to blend it in. Leaving excess stain on the surface to dry will result in an unappealing shiny finish.
do I need to have a 24 hour period of time with temp between 50-70 degrees to apply stain? what if, after application,
it drops below 50 at night
It can drop below 50 the first night but it should not drop below freezing.
Stained 4 years ago with TWP 100 (Pecan) after letting new cedar deck dry 8 months, then doing the recommended cleaning and brightening. Verticals in pretty good shape still and I can imagine will come up well with cleaning etc and re-staining with same color TWP 100/120. My concern is the horizontals – where the stain seems to be partially gone in some areas and mostly still there in others. Can I just clean the horizontals like normal, or do these need to be stripped before re-coating? Oklahoma – high heat, high UV and freezing during winters. Thanks!
Yes, strip and brighten for prep since it has worn unevenly over the years.

I applied TWP stain yesterday and noticed I unintentionally went lighter on some boards compared to the rest. Can I still add another light coat today (next day) to make it more even? Has not been 24 hours.
Typically no. Second coats gave to be applied wet on wet.

400 sq ft deck (new, pressure treated 5/4×6 boards)
When to apply 1500 series?
Gallons needed for two coat wet on wet application?
The new wood needs to weather. Do it in the Fall. See link for prep and applying to new wood:

How me I know the finish of the product?
Sorry but we do not understand your question.
Just stained my deck with semi transparent stain I ran out of stain about 4 feet from the end but it had a very small coat on it what will happen if I coat it 2 weeks later will it work or how do I make it work it is rad stain
Once the first coat has cured you cannot add more for about 6-12 months and after prep.
I applied the new coat 2 weeks ago and now see the instruction to apply a “wet on wet” 2nd coat. Missed that. Any prep recommended before another coat?
You cannot apply another coat now since it has cured. You will have to wait 9-12 months and then prep before applying.
Can I spray or apply TWP deck stain with a pressure washer using low pressure?….Will it not work or not for use in a pressure washer?
No, you cannot apply a deck stain with a pressure washer.
Can you use mineral spirits to clean off excesss twp on deck?

Should I apply TWP 100 to the underside of the deck boards?
No need.
What if the only stain the wood has is the original stain the wood came with prior to being installed??does this still need to be stripped?
If a different brand of stain then what you plan on using then yes, it has to be removed.
can I use TWP which is 3 years old?
Most likley it has gone bad.
I’m confused about the “wet on wet” guidance. The recommendation is to apply a second coat after 30 minutes, most likely when the most recent stained boards are still a wet. So on a deck, wouldn’t it mean that we may need to walk over the most recent stained boards in order to apply the second coat so soon? And since it may take about two hours to stain the first coat by brush, could I re-start when completely finished the first coat all over? Why the wet-on-wet suggestion? Thanks

Hard to say for certain as it depends on the porosity. Do a test board and see how it dries after a day or two. Make sure it is not sticky or tacky.
Cleaned my deck over two weeks ago and weather not cooperating. It maybe awhile before I can stain/preserve it. When the weather does cooperate can I do a lite powerwash to clean? Or do I have to use a deck cleaner again? What does the temp and humidity level need to be for application?
If it has been longer than two weeks, you should redo the prep by lightly pressure washing. use a cleaner if it has gotten dirty in that time. Temps are 50-90. Humidity does not matter.
Airless tip size recommended for a fence
Any fan tip will work. Wider is easier.
Just properly cleaned deck and now the weather is not complying. How long do I have to put stain on? How long will deck stay clean (neutralized with oxalic acid)?
How long should deck dry after mild rain?
How long does it take for stain to dry and then cure?
Stain within 2 weeks of prep. 48 hours after rain to stain. Dries in 6-24 hours.
I have an outside handrail that I will stain (no previous stain so will clean prior ). I remember reading a recommendation to not stain all sides of the wood because of possibility of lack of air flow preventing drying. Would that also apply in this case where a handrail is completely open to the elements ( except for where it mounts to brackets)?Thanks in advance for your advice!
All exposed wood is correct for this.
Many thanks.
I am needing to stain a pergola to match the fence (using TWP dark walnut). The fence (made of pressure treated lumber) is only a couple months old whereas the pergola is several years old and wood has turned the typical gray. Was planning on mixing the stains and testing to be able to achieve the same/or very close for the fence and pergola. Can I do that? Also, do I need to do anything other than power wash the pergola before staining?
Use the Gemini Restore Kit for prep for all wood. You can mix colors of the same series.
My contractor used TWP last year when he built the new redwood deck.
I would like to put another coat of stain on this year as it already looks weathered… reading this stuff, do I have to strip my wood EVERY year that I want to reapply a coat? What happens if I just put another coat on top?
Also, how can I clean the deck without harmful chemicals or bleach for the plants and wild animals below the deck?
You do not have strip but you have to prep. Use the Gemini Kit. https://www.twpstain.com/gemini-s-restore-a-deck-cleaner-and-brightener-kit
You cannot recoat without prepping.
What happens if you don’t prep it? I recoated my pergola and fence with the same TWP that was used the prior year (before I read all of this) and it looks great. I’m wondering why it is so important to clean and prep if the wood isn’t that dirty?Thanks.
It will not look good, probably prematurely fail, and your warranty will be void.
Well, I recoated without the prep solution 5 months ago and it still looks great.
My deck is situated over a cloth-type covered lower deck. It can’t be removed and would be very difficult to cover. The biodegradable Gemini cleaner says to wet down all vegetation before and after using the cleaner… will the cleaner ruin my lower deck covering?
Not sure, best to test a spot first.
My plan is too re seal/stain my deck with the same TWP product (picture) that I’ve used before. One note – the deck boards were some type of pretreated to provide maintenance free decking.
The contractor that applied the last time over applied the product which left white spots of residue (picture) on the deck. Should I fully remove the old product from deck boards before I add a new quote? What will thin out or remove the white residue spots as pressure washer didn’t fully remove them? Am I using the right stain sealer product? Any other recommendation would be appreciated.
Yes, use the RAD stripper and brightener kit for prep here. You are using the correct TWP.
I have a relatively new pool deck. I let the wood weather the last year and I’m ready to stain this year. Do I need to do 2 coats with new wood?
One coat, see this for tips: https://www.twpstainhelp.com/prepping-new-wood-for-twp-stains/
