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.

    I live in northeast OH. Would you recommend 100 or 1500 Series for cedar log railing and treated lumber decks? Decks previously stained with semi transparent Sikkens product 3 years ago?

      For Ohio you need the TWP 1500. Make sure to remove the Sikkens first.

    Live in Marin county in northern California and we are re-staining a year old deck. Was originally stained with Thompsons water seal and it looks bad after 1 year (My contractors choice unfortunately). It's a redwood deck that gets sun from 1pm on. Looking to stain with the TWP 100 redwood semi transaparent. Question is do we need to strip and brighten? Also would you recommend 1500 instead of 100? Thanks in advance.

      Strip and brighten and use the TWP 1500 for CA.

    I read the two descriptions of TWP 100 series and TWP 1500 series. With that being said with one is the easiest one to work with? We live in Michigan and our deck gets blasted by the afternoon sun. Thank you for your opinion.

      They apply and last the same. Most use the TWP 100 in MI.

        Just curious, why TWP 100 in Michigan versus TWP 1500. I’m in the process of purchasing stain for my deck, fencing and covered porch in Michigan. All 10+ years old

          TWP 100 is VOC compliant for MI and is what has been used therefor 30 years. You can use the 1500 if you would like but there would not be an advantage.

    Cedartone on pine, and then natural on cedar?

    I have a Big Green Egg table made from cypress that has never been treated. It has some mildew spots and has been in my garage for the past 3 years. It’s time to treat it and put on the back porch. Which TWP series is best and why? Thanks.

    Which stain would be best for an outside tongue & groove ceiling and will I need to sand the wood before staining and should I stain both sides?

      If new wood then clean and brighten for prep and apply one coat. No need to sand. Only stain the exposed wood.

    There is mold on boards so without retreating they are good for another 25 t0 30 years. Putting composite deck on top

      A sealer will not prevent mildew or mold not would it last for 25-30 years. Best to just clean this off prior.

    We have a one year old cedar deck around our pool. We plan to seal it in June. It gets good sun until around 3 p.m. then it starts to get shade. Should we go with the 100 or 1500 and what would be the reason? Thank you

    We live in NE Florida. Our 4 month old PT deck sits on the south side of the house, so it will get intense summer sun. Should we use TWP 100 or TWP 1500? How long should we wait before we stain the deck? Thanks.

    I have cedar vertical siding that is 34 years old. It has been restrained every 9 years with Cabot semi solid -mission brown. I have washed the house and removed the black mold- which of your products would you recommend and a color.
    I live in NYS

      You will have to remove all the Cabot 100% first before using the TWP stains. Did you do this?

    We put up a privacy fence about 4 weeks ago. Trying to do my homework on stains. I am considering the TWP 1500 in Natural to keep the appearance of the wood. Would that be your recommendation?

    Hello, staining a 10 year old deck that is in good condition and been cleaned and prepped properly. Half of the deck is almost always shaded, and the other half gets about 5 hrs of sun. Probably going with honeytone. I'm in Ga. Would the 100 or 1500 be my best choice?

    Hi, We have a one year old pergola built out of white cedar. We sealed with Cabot's Exterior clear sealer last spring because we wanted to keep the natural color of the cedar. The color has faded to an almost pale yellow and some boards whiter. We do not want it to gray or mildew. What should stain would you recommend? It gets full sun! We need to seal again ASAP!
