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.

    Thanks for the info. A couple other questions-- what is the average for how long it will last before it needs to be redone? When it does need to be redone, can we just apply another coat? How long will it last after the container has been opened? For instance if we get the five gallon and only use half of it...will it store ok to use again in the future?

    Typically lasts about 2 years. Can be cleaned and recoated own the road. See this about Shelf Life:

    We moved into a house recently in SE MN that had a deck built last year in the spring/summer. It hasn't been sealed yet. Which is better to use-- The 100 series or 1500 series? What are the differences between the two? It gets a lot of sun in the warm/hot months but needs to stand up to Minnesota cold, snowy winters. Are you able to use a sprayer or would it be best to use a pad? Thanks

    Use the TWP 100 Series. Prep first with the Gemini Restore Kit. You can spray you will need to back brush the products,

    I live in NH. My deck was most recently covered with Behr solid deck stain. Can I go over it with a little prep or do i need to completely strip. Which of your products do you recommend?

    You cannot apply TWP over a solid stain or any other stain of a different brand. Solid stains will need to be sanded off as a stain stripper will not remove a solid stain.

    I have a heavily shaded deck that is blanketed with mold and mildew during winter months. Which stain would work better--1500 series or the 100 series (both legal here)?

    I have sanded down the cedar deck with 80 grit sand paper. Can stain be put directly on it now with semi-closed fibers?

    I have new windows that were put in my home the exterior of them is aluminum clad the interior is wood. They come with the wood unfinished and I have to stain and poly them to prevent moisture sun damage. Can I use the TWP 1500 on the interior wood trim of window instead of wood conditioner-stain-3 coats of poly? I used this stuff on my deck this summer and it has been awesome so far. Yes it takes forever for the odor to go away but it seems like it would be a great UV and moisture protecter for my windows.

    Yes you can but poly cannot be applied on top.

Full sun highs 80-90 deg. in the shade lows 60 in summer 50 deg. high low 28 deg. in the winter, usually above freezing in the day in the winter.

    I built a new pergola 2 years ago out of rough western red cedar. I used a stain/ sealer they sold me where I bought my lumber. It was TWP in cedar tone not sure which type 100 1500 etc. it still looks good but was going to give it another coat. What should I use and will it take another coat?

    Clean lightly and use the 1500 Series.

    I was going to purchase the 100 series. What is the difference between that and the new 1500 series. I see it replaces the 500, but no description on what conditions it was best suited for. I live in Northern Idaho. Mountains, cold winters, lots of snow, dry summers. Not a high humidity environment. Back deck gets all the morning sun, shade by mid afternoon. The front decks get the brutal hot sun from early afternoon on. Can you advice which series you would recommend? Thank-you Nikki

    You can use either for this deck in UD but most would use the 100 Series.
