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.

    Tanya Ha:
    Good day, we just finish building a 600sq ft deck. We used kiln dry western red cedar, I know there is a weathering process of a few months. It's been almost a month since we purchase the boards, Does that still apply if the deck boards are kiln dry?? We live in Seattle, which rains a lot. Which twp do you recommend? Thank you!! Feeling overwhelmed

    A month is good with kiln dried. Prep with the Gemini Restore Kit and stain with 1 coat of the TWP 100 Series.

    Jane McGinty:
    Which stain should I use on an old cedar deck built over a flat rubber roof? I've been told not to use an oil based product because I can not protect the rubber.

    TWP only comes in an oil based stain. Never heard of the TWP harming rubber roofs.

    We have a pre treated pine deck which we have treated with Thompson Water Seal at least 3 times in 14 years. Now we need to do something. We power waahed the last couple years. But what do we need to strip, what stain do we then apply? Our deck needs to be revived. Some is under cover big portion in direct sun & weather. Thank you in advance for your guidance.

    It would be best to strip with the Restore A dEck Stripper/Brightener Kit for the prep. Use the TWP 1500 Series.

    The Sledge:
    Looking for the best TWP stain for two different applications in Southern Wisconsin:
    1. New horse fence with cedar posts and white oak boards.
    2. New pressure treated tongue and groove (used as barn siding).

    Thanks!

    Use the 100 Series for both as it will penetrate the new wood better.

    Why don't you promote TWP200 as much as the TWP100 and TWP1500? When is it better to use TWP200 over the others?

    The 200 Series is mostly for shakes and shingles.

    Loretta:
    I have a can of TWP 1501-1 left over from staining my deck in 2015 and I wondered if I could use it on a potting table made of fir.

    The table is meant for indoor/outdoor use. The instructions say that it has been treated with an oil-based stain but if used outdoors, staining or repainting with an oil-based weatherproof coating of my choice may increase the life expectancy.

    Thank you.

    You can use the TWP but you cannot apply the TWP over the current coating. That would need to be removed first.

    Becky Brauchler:
    Should the stain be applied to all sides of cedar siding before it's installed or can it just go on the exposed side after it's up?

    Exposed areas only after install.
