Which TWP Stain Should I Use?

TWP stands for Total Wood Preservative. It has been around for over 20 years and has been a leader in the wood staining industry. TWP Exterior Wood Stain is an EPA registered wood preservative. Unlike other stains that cover up wood and form a protective film that is venerable to peeling and flaking, TWP stains are a penetrating oil formula that offers excellent protection. Knowing which TWP formula is best for your exterior wood project is the key to having excellent results.

TWP 100 Series – The 100 Series has been a leading and respected formula for over 25 years. It penetrates and enhances natural wood beauty and is available is 6 different colors. It is used for all types of exterior wood decking, siding, fencing, and hardwoods. It is not prone to mold or mildew. The 100 Series is not compliant in all states. Please be sure to check if it is compliant in your area. 

TWP 200 Series – Available in 8 different colors, the 200 Series formula is best used on wood siding, shakes, and shingles. It uses a non-drying paraffin oil formula that enhances the wood cell’s structural stability making it an excellent choice for older wood that has lost its natural oils. It sheds and repels water and prolongs UV fading. The TWP 200 Series is compliant in all 50 states.

TWP 500 Series – The TWP 500 Series formula has been discontinued and replaced with a new and improved formula called TWP 1500.

TWP 1500 Series – The new 1500 series replaces the old 500 series. This newly formulated preservative penetrates better, dries faster, and outperforms it predecessor. TWP 1500 is a low VOC preservative with unique absorbing pigments that prevent wood graying, fading and premature discoloring. Selected mildewcides prevent the growth of mold and mildew. Available in 9 different colors, TWP 1500 Series Stain is best used on all types of wood fencing, decking, siding, log homes and roofing. It is compliant in all 50 states due to its low 250 VOC formula.

Choose the TWP Series Stain that best fits your needs and give your wood surfaces the protection and lasting beauty they deserve.

    We're looking to re-stain the decks at our house in the Bay Area of Northern California. They were last done in 2015 with a 50-50 mix of 205 & 1501. If doing this myself then I'd like to switch to just one series - which should I use?

    Getting ready to stain our 2- 1/2 year old uncovered pine deck for the first time. We live in KY, the deck faces northeast, gets morning sun, and backs up to a wooded area. As you can imagine,  it’s quite weathered, has  areas of mold, and some wood-splitting. What stain product would you recommend? As we’re not very timely with our home maintenance projects, a long lasting stain would be nice.

    Hello, I love in the coast of oregon and gave a cedar shake roof. I previously used a chevron oil for preservative. Its 25 years old. The shakes have lost some thickness. Lots of rain, wind and salty air.
    Should I use series 200 or 1500 series? Where is the closest dealer or can I order it direct from you?

    I’m resurfacing a deck in Richmond Virginia. Currently gets afternoon sun but part of the build will be a privacy wall and sun sail to reduce that. 

    Planning to go with a darker brown for both aesthetics and added UV protection. 

    Which of your products do you recommend?

    We just purchased a 1990 Linda cedar home in western Washington (lots of rain). Cedar siding is currently stained with unknown stain that is peeling. 1. What is the best product to strip this stain and prep the siding? 2. What is the most durable series of stain for our state?

          Unfortunately what you have on your wood most likely cannot be stripped. It looks shiny, like a varnish and that means stripping will not get it off. To get it off you would have to use media blasting or corn cob blasting and that means hiring a pro.

    I live in Colorado in some intense sun. About 7 years ago I stained my deck (skirting and railings) with TWP 100 redwood. It's held up great, but due to fading and weathering, it now needs to be redone. However, I can't order TWP 100 to Colorado anymore. Should I use TWP 1500 instead? Will it go over the faded TWP 100 okay or is there other prep work I'd need to do? And is the TWP 1500 redwood the best color match for TWP 100 redwood?

        Looked at the 1500 stain colors. I have a solid white colored stain on my deck currently. Plan to stain over that color without sanding or removing. Any recommendations for a stain that would blend with or cover my current stain for a pool deck in PA that you offer?

          No, TWP stains do not come in a solid stain and they cannot be applied over a solid stain. You will need a solid stain again.

    Would it look funny to use TWP 1500 Dark Oak for a porch railing and balusters I'm about to add when I already used TWP 100 Dark Oak on the deck and steps I've already built?  Everything is/will be built from redwood.  I ran out of the 1 gallon of TWP 100 I had, and it has since become more convenient to get TWP 1500.

      They are close in color but not exactly the same.

        I understand that even when using the same product, with some wood stains there can be a risk of slightly different colors, if all the cans used aren't first mixed together to make it all uniform.

        Is the difference in color between TWP 1500 and TWP 100 likely to be more noticeable than different cans of 100 that weren't combined?

    I have a ten year old cedar deck that I have sanded back to bare wood. I looks clean with just a few gray patches. 1. After brightening, should I use 101 or 1501 - I have both on hand. 2. I was planning on applying the TWP twice since the wood is bare - any problems with this?

      For CA, you will need the 1500 Series.
