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

The 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 have approximately 50-6'x8' panels of prestained western cedar privacy fence. It's been installed now for a year with little change in color/appearance. We would like to restrain now per our contractors advice. Should we use the twp 1500 brightener kit? Or just pressure wash and then apply the twp 1500? And how much is necessary for both sides of that size fence?

      Use the Gemini Restore Kit for prep and stain. You will need about 40-50 gallons for the two coats and both sides.

    I am considering applying TWP 1500 over huge fence that was stained 7 years ago with Olympic honey gold semitransparent oil based stain. Should I use stripper, then brightner, and power wash, and then stain?? At this point, proper prep is the only thing I am not sure about

      Stripper, pressure wash, brightener, rinse, then stain.

    I ordered Color Natural 1530, might be too light, couldn’t cover wood filter color. I just finish 1st paint with 1 Gallon. Any suggestion? Whether 2nd time paint useful? How much I need order this time? Thanks!

      Wood filler does not work on exterior wood. It will not "stain" to match and will stand out as white spots everywhere.

        Oops.. is there any way to remove it or cover it? How about stain 2 coat with different color, e.g. 1516 Rustic? This is 4 year new wood without any stain. I just finished one coat with natural 1530. Do I need stain 2nd coat month later? Thanks.

          There is no way to stain it with TWP to blend. Sorry. Not sure on removing it. You would have to ask them.

            LL · 08/28/2018
            Thanks! For my 4 years unstained new wood, I only applied one coat now. Should I apply another coat within 9-12 month?

    I am looking to apply TWP 1500 to a new treated wood pool deck (which has aged for 14 months). The deck wraps around the entire pool and has 100 or so spindles. I am planning to remove the mill glaze from the floor and rails but do the spindles new cleaned? If so, what would be the easiest way to clean them?

    I am re-applying the 1502 Redwood (same product) on a fence originally stained in 2015. Besides the TWP 1500 Series and Gemini Cleaner/Brightener Kit, should I be concerned with any other cleaning or preparation steps. I am applying to redwood fence boards and 2x4 studs. Thank you.

      No. Just use the Gemini Kit for the prep.

    Would your 1500 stain be the product to use on existing siding. It was originally done with an semi transparent Olympia stain.
    • We will reply to your comment shortly
      TWP Stains · 07/03/2018
      Yes, but you will need to remove the Olympic first by stripping and brightening.

    We just built a cedar deck on our house with lumber purchased from Menards. How long do I have to wait before staining? And will I need the cleaner/brightener kit? Thanks!

    We have a 1400 sq ft deck that needs some love before a wedding to be held in August. I know we are pushing it time-wise, but there are some boards that need to be replaced (redwood) and it needs to be restained. We used TWP100 natural last time. We want to go clear this time. What steps should we use and how much of each product should we buy. We are prepared to sand the whole deck. Do we use Gemini, then sand, then stain? And the new boards? Do we wait until we are done with the rest of the deck then install them and treat them in a few months? Or just include the new boards in the process and know we'll need to readdress the deck sooner than normal? THANK YOU!

    Also... any major issues if I apply in over 90 degree temps? I live in Houston and will be looking to apply the stain soon. Weather is currently mid - high 90's, high humidity, and will only increase as summer moves on

      No higher then 95 and avoid direct sunlight if possible.

    Could I also get away with using one cleaner / brightener kit for this same size fence?

    Patrick · 06/26/2018
    Would a 5 gallon pail of stain be enough to cover a roughly 1200 sq ft fence? It would just be one side.
    • We will reply to your comment shortly
      TWP Stains · 06/26/2018
      No, you would need about 10-12 gallons for the two coats.

    2 1/2 years ago we purchased a HUD home that has a deck (after removing an entire section, is now 996 sq ft). It appears the wood has not had any type of stain/protective treatment on it in many years - if ever.
    We have power washed it 3 or 4 times and, when freshly cleaned, it appears the wood is clean.
    Is it necessary to use the cleaner prior to applying a stain?

    I’ve read quite a few recommendations from professionals stating they would apply one coat & wait a couple months to apply a second coat. I also noticed your recommendation is to apply the second coat while the product is still “wet”. Define wet, please! How do you walk on a wet surface to apply the second coat?

    I have a log cabin that I have used TWP cedar tone stain on for many years. I'm getting ready to do it again, but was wondering if the cleaner and brightener needs to be used on the logs before applying stain or if power washing would be sufficient?

      Best to use the Gemini Restore Kit for the prep. It will do a better overall job than just using water.

    I used Gemini Cleaner and Brightener on my deck, and used a power washer to rinse. The pics are of the "after". Would the stripper work, or does this require sanding? I purchased the Rustic 1500.

    The third pic is pretty washed out, the real deck looks darker, like the first two pics.

    Pressure treated deck 12 years old. Used TWP redwood 3 years ago. Some color still remains, but some shady spots started to mildew late last year.

    Changing to Dark Oak this year and wondering if the deck cleaner and brightener will suffice for the prepping process?

      Hi Chris, no use the Stripper and Brightener kit for this. Very easy to do.

    I'd like to restore my deck to it's original condition. I purchased TWP's cleaner and brightener. Followed the steps and applied the stain as directed. An unexpected shower came through before the required dry time and I the my deck has mold and washed off sections of stain.

    Having done the prep and staining once, I've decided this is not something I'm interested in doing every few years (my deck is 650 square feet). The maintenance is more than I'm interested in. I'd like to remove the stain and let my cedar deck return to it's natural finish. Any suggestions for removing the old TWP stain?

    Mike Martin:
    I live in Chicago, IL and have a new deck (Southern Yellow Pine) that is about 1 yr old that is ready for stain. Is the cleaner/brightener needed before applying the stain or can I just pressure wash the wood? If the cleaner/brightener is needed before applying the stain, what is the shortest and longest time frame that I have between cleaning the deck to applying the stain?

    Use the Gemini Restore Kit while pressure washing. Stain about 48 hours later and try to stain within 2 weeks of the prep.
