We are here to help you with your TWP exterior deck or wood restoration project!
TWP is a cutting-edge wood preservative and protectant registered by the EPA, designed to provide exceptional protection for exterior wood surfaces. However, its performance and longevity can vary based on several factors, including the type and age of the wood, how well it is prepared, and the application technique used.
To ensure the best possible results with TWP 100, 1500, or 200 Series, proper preparation and application are key. Follow recommended guidelines to maximize the durability and beauty of your wood surface, no matter which TWP series you choose.

What is the recommended process for preparing a 10 year old pressure treated pine deck that has Behr deck paint that I would like to remove and apply TWP semi-solid stain. Can chemical paint remover be used or should the paint be sanded off. How long between old paint removal and application of the TWP stain? I assume the process would be remove old paint, (sand?), brighten, dry 48 hrs., apply new stain.
John, paint removal can be done, but it can be a challenge. It has to come off fully before using the TWP stains. See this article for tips: https://www.deckstainhelp.com/how-to-remove-a-solid-color-deck-stain-or-paint/
Hello. I have smooth cut cedar porch posts that are 5 yrs old and originally finished in some sore of satin stain and sealer. The majority of the exterior sides have faded and flaked off. The interior sides are in better shape and have some remaining finish. I plan on sanding them down. Would I still need the cleaner if I am sanding them? I do plan on using the brightener but want sure about the cleaner. Thanks
Yes, see this for sanding tips: https://www.deckstainhelp.com/how-to-sand-your-wood-deck/
What type and color of stain would you recommend for my new cedar fence? I would like to keep the original color and prevent it from greying. I live in the Pacific Northwest.
Look at the TWP 1500 Series. For color ideas, see here: https://www.twpstain.com/topics/twp-1500-series-stain-colors-and-photo-albums
Rough cut cedar siding, 40 years old. I’ve used different stain/preservatives over the years. 4 years ago I used Behr translucent waterproofing wood finish. What prep products do you recommend. I want to switch to TWP cedar tone 1500.
Please add some pics in the comments for help with the prep.
Does this help?
Use thsi kit with both additives for the stripper:

I recently purchased the restore-a-deck stripper and brightener from you. Will either product damage my metal balusters?
It shouldn’t, but always test the spot first.
Can I install 1500 with a roller? If so what nap
