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.

    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.

    The Sledge:
    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.

    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.

    Is it OK to use this stain on the interior of a log cabin. I think it's what they used originally on the inside and outside but i'm not sure.

    You can use TWP indoors, but being an oil based stain, it will have a strong odor that could take days to dissipate. You should vacate the home and make sure it is properly aired out after it fully cures.

    We just added a covered porch to the front of our house. The Posts, beams and rafters are cedar, sanded, but not smooth. The ceiling is c-grade v-groove pine. The floor and handrails are kiln dried pine. The doors are fir. The roof overhang is significant and we have gutters across the front. We are in Alabama and the house is on a wooded lot. I would like to use TWP products exclusive for the entire job. I got samples in the 1500 series in Pecan, Dark Oak and Black Walnut. I love the Pecan on all the cedar, but it's too light for the rest. I love the Dark Oak on the pine and fir, but it doesn't deem to penetrate either very well. Would another series work better for those? I need to stain everything ASAP, but I'm not sure what to buy. Thanks for your help!

    You are staining too soon, that is what it does not soak in. See these articles:

    The 100 Series does have better penetration for newer wood.

    TONY L:
    I power washed my salt water dock and want to use the best penetrating stain available. The dock is in good condition but does have some small cracks so I need a stain that will deeply penetrate the wood. I prefer a darker color (grayish) than a light color. What do you suggest?
    Tony

    You can use the TWP 1500. We do not have a dark gray color though. Maybe a dark brown like the Dark Oak?
