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.

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.

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?

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

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?

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?

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!

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?

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?

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.

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?

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.

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?
