TWP 1500 is a Semi-transparent Oil-Based wood stain and preservative that is allowed in all 50 states.

The new TWP® 1500 formula is designed to penetrate better, dry faster and outperform the previous TWP® 500 series formula.

TWP® 1500 Series is an EPA registered wood preservative which prevents structural damage and wood decay on exterior above ground wood surfaces such as fencing, decking, wood siding, log homes, and roofing. TWP® 1500 Series resists water absorption that causes warping, cracking and splitting as well as preventing freeze damage in colder climates.

TWP® 1500 Series is a low VOC preservative with special U.V. absorbing pigments that prevent unsightly wood graying, darkening and fading. The selected mildewcides inhibit the growth of mold and mildew which assist in preventing premature discoloration.

TWP® 1500 Series will keep your wood beautiful, fresh and looking new longer. The ease of application and maintenance will allow you to enjoy your investment for years to come.

I did the deck stain calc for 900sqft and it indicated I should get 9 gallons. But the Stain Info said each gallon covers 150-250sqft. Which means 4-6 gallons. So I don't over order, what would be good? This is only for a flat surface, no railings.

    lomalinda, sounds like it. TWP should not be shiny. If it is than it did not penetrate. I would wipe down the deck with mineral spirits and rags to remove some of the excess and let it dry for a few more days. Make sure to wet rags down with water to avoid spontaneous combustion. It will be fine once it dries and is not sticky.

    TWP 1500; New Jersey - My husband stained our deck 15 year old deck yesterday. It has never been treated before. It was powerwashed a few weeks ago and then we had rain, so we waited for several dry days to stain. He did 2 coats - within about 20 minutes of each other, using a roller. This morning we have a few boards that still look wet - shiny. Did we use too much product? Our thoughts, it either it will eventually soak in or we should wipe with a cloth. Do you have a recommendation? What impact will too much product (if that is the reason) have on the useability of the deck and effectiveness of the treatment?

    GB, either color would work. Best to get some samples to test first from our site.

    I have a cedar deck, 568 sq. ft. Would it be recommended to use the cedartone or natural? Are there any pictures of a cedar deck using each?

    Jerry, I would apply the 100 Series. If you do it prematurely than it will most likely fail earlier requiring it to be redone next year.

    I recently completed two redwood decks. I live in WY where we get lots of snow in Winter. Should I use TWP 100 or 1500? If I wait the recommended minimum 4-months before staining, the weather will be COLD here. Should I wait as long as possible and apply just one coat now, then a second one next summer? OR? Thank you.

    We have 7 year old decking around 3 sides of our house that we have just finished cleaning. Most of it is stained a beautiful warm light brown that lets most of the wood grain show thru, the rest has never been stained or was clear.
    We will be staining the whole deck area, which color would you recommend to try and keep everything the same warm light brown color (multiple type woods used some had stain some did not). I didn't know if I should go w/the cedar tone (instead of the honey) because it is a little darker and might help everything match.

    Ric Popp,

    The main thing you did wrong is you sanded with to fine of a grit of paper. Out side wood is not supposed to be smooth like an interior floor. No higher the 60 grit is what we suggest. You may run the risk of the TWP not penetrating correctly now. This would create a fill on the surface that may wear or peel. Another concern is that new wood should weather for 4+ months, then prepped by cleaning and brightening before applying the stain. At this point I would let is "weather" for a couple of months then prep with the Gemini Restore Kit and a light pressure wash in the Fall before applying the stain.

    lomalinda, you should always use a deck cleaner and wood brightener when pressure washing. This will help with the overall final appearance and prevent damage to the wood when washing with water alone. TWP 1500 for this deck.

    I want u to grade my prep work please. My deck is 90% cedar(old) 10% Douglas fir(new).The cedar has been sanded with 80/100/120 grit, using an orbital sander. Douglas fir not sanded. Both the cedar and Douglas fir stripped and then brightener applied. Both were thoroughly rinsed with water hose during and after each process.
    I'm deathly afraid upon application of TWP 1500 stain that the deck will turn out like the last application of stain ,which was Sikkens. The Sikkens Honey Tone flaked and peeled w/in 6 months. I don't want this to happen again! I've been advised buy a paint employee at Lowe's not to pressure wash the deck now, prior to staining.
    Have I done a correct prep job, should I pressure wash prior to staining?
    I want this deck to look as good as possible in order to sell my home next spring. I'd appreciate any all feed-back on my situation.
    Thank you, Ric Popp

    My husband is currently power washing our 12 year old pt wood deck. He asked me to research best stain. Wow. I think I should have offered to do the power washing! ;-)
    The deck has never had any type of coating/preservative/stain whatever; in NJ; sometimes snow sits for months in the shady parts. Would like to use the TWP 1500. Good choice or is there better suggestion? Since he is power washing with just water do we need to use something before applying the stain? Any other comments/suggestions/advice obviously welcome. Thank you!

    Laurie, yes you need to prep with a cleaner and wood brightener first. You can use the TWP 1500 Series for this. We are located in Rochester Hills, MI.

    I have 2 Large Pergola's built out of treated lumber, they were built in Aug. 2012 and have not had any product on them at this time. I was wondering if you would recommend TWP 1500, do I have to clean it in any way before staining, it is going to be very difficult to do as it is high with several angles. Was thinking of using a stain mitten, or any suggestion you may have. I live in Michigan, is there stores here that sell this product or do I have to order it, hoping to do this ASAP.
    Thank You, Sue
