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.

We have used this product twice on our pressure-treated wood deck (. It applies easily and looks terrific when done. We are DIYers with limited experience with this sort of project, and had no trouble following the application directions. We had to address a lot of wood damage before applying it--severe UV damage, mold and mildew--but with the right prep, we couldn't be happier with the outcome. The second time we used it, we did over-apply a bit and had a lot of shiny excess stain after a few hours of drying. We read the tips here on the website and the next day we wiped off the excess using a light misting of mineral spirits and shop rags. Easy fix and it looks great. Never any peeling, which is just what we wanted, and it made our heavily damaged wood look better than we thought possible. I love finding a product that works as well as advertised.

    I have some hatchway doors being built to replace our old ones that are rotting. The new ones will be tongue and groove pine. My biggest fear is warping. Would it be ok to seal them with 1500 series before they get mounted? They are being assembled off-site.

    Do you recommend power-washing or sanding or otherwise prepping a mangaris fence (previously stained) or can the 1501 be applied over the top? Curious about the process and what additional cleaning/prep I may need to do before applying the 1501. Thanks.

    I rebuilt the posts and trimmed with new cedar of a 15 year old pergola.  The upper portion is power washed and ready for 1500.  How long should I wait to brighten and use 1500 on the new cedar posts?  Located in Michigan.

    We clean and brighten our porch every year to prep for staining with TWP 100 series. This year, due to availability, we stained our porch with the 1500 series. We have been completely disappointed in the 1500 series and want to return back to the 100 series on the porch. Could you please indicate the process necessary? Can we clean and brighten to prep for 100 series stain? Would stripping be necessary? Why?

    Is this deck ok to stain? It's a bit blotchy with mildew/algae/green stuff. 
    • We will reply to your comment shortly
      TWP Stains · 08/03/2023
      The algae is imbedded in your wood grain. Try bleach to kill it. 1 part to 4 parts water. Rinse well with water when done.

        Ok do I need to re-strip or brighten? It is starting to look less blotchy as it dries out (I did it yesterday with a pressure washer) but not as clean as some other pics I've seen.

    I have used the TWP 101 cedartone on my deck for the last 5 years now I am switching to the 1500 series which color in the 1500 series is closest to the old 101 color Thank You

      1530 Natural is closest to the 101 Cedartone.

    I just put a coat of the Earth color of the semi transparent stain on.  Do you think it needs a second coat?
    • We will reply to your comment shortly
      TWP Stains · 07/26/2023
      No, and if doing a second coat, it has to be applied within 20-60 minutes of the first coat. We would leave it as is.

    I have a cedar fence that I have used TWP on previously. I don't remember which one I used but want to preserve the natural color of the cedar. It has not grayed at all.

    I have a deck that has already had 1500 series deck stain on it. It needs to be recoated. Besides a gallon of deck stain what else do I need to re-stain it? Does it need brightener or stripper?  If you can run me through the process, that would be very helpful. Thanks much!

    I had been using TWP 100 series which you no longer ship to my state. Is the 1500 series as good as the 100 and if so why do you still offer the 100 series? Can you use 1500 over applied 100 series? Lastly are colors consistent in the 1500 series compared to the 100 series

      Strip and brighten when switching series. 

      Colors are not exactly the same between series. Let us know which color you had for closest color in 1500 series. 

      The 1500 is just as good. Most states can still use the 100 still so need to discontinue it.

    How many coats do you apply to an old deck? I asked about Cabot and was recommended to buy Armstrong but I'm also looking at TWP 1500. Which of these would you choose?
    • We will reply to your comment shortly
      TWP Stains · 07/12/2023
      Use the TWP 1500. 2 coats applied wet on wet is correct.

    I stained some new Pine board and batten siding a couple years ago after letting it age for 9 months over the winter.  I used Rustic 1516.  A year later and I feel like the color has become much more orange than originally when I stained it.  I’d like to strip it and re do it with Pecan 1520.  Will your stripper products allow that color change?.  If so, what stripper cleaner do you recommend?    Thank you.

    I have semi-solid SuperDeck oil based stain on my redwood siding. It is no longer available. (Seems that everything is migrating toward water-based acrylic, which apparently not recommended for re-staining redwood). Will TWP semi-transparent oil based be suitable to apply over my siding? Also, my siding has a pleasing flat dry appearance to it. Will TWP give it an oily/shiny look?

      You cannot apply TWP (or any other brand) over your Super Deck unless you fully remove the Super Deck first. TWP is not shiny.

    This summer I cleaned, stripped, and brightened our decks. Because we have some areas that receive full unrelenting sun and other areas that are perpetually in the shade, I decided to use TWP 1500 clear. After stripping the boards down to original wood they look great and the clear finish will hopefully allow the natural wood grain to show through. My question is more about maintenance. Next spring is there anything I should do to keep the decks looks great after all the work I did getting them ready for waterproofing?

    Recently sanded mahagony porch to get old varnish off. Rented a standup orbital sander from Home Depot but I still see some hints of yellow left over. I assume this is spots or streaks of varnish that didn’t come completely off. Is it ok to power wash then stain this as is? I cannot go back and rent a sander again and have hand sanded as much as I possibly could. 

    also, if I power wash and wait a week or two because of rain is that ok? Or does it need to be power washed 2 days before

      Send some pics while the wood is wet. This would show if the yellow is old varnish or not.

    My daughter has a small deck in Chicago made of pressure treated wood. The wood was coated with a solid Behr stain ( found a can) that has failed, probably due to an application before it had a chance to weather. I have had to use 36 grit sandpaper to remove the stain. I want to use TWP 1500. The 36 grit did not tear up and wood. What should be my next steps? Sand finer, deck wash,etc?

    Thanks in advance

    Will this protect tongue and groove mahagony porch? Just sanded the old varnish off but now I’m thinking the varnish would hold up better to winter by preventing water getting between boards and expanding? It’s basically hardwood floors outside, about 90% covered so the parts in the sun/rain get beaten up

      Varnish peels on outside wood and is never suggested. Use the TWP.
