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 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

    Installing a new rough-cut red cedar pergola on the west side of my house in SE Minnesota. Not sure of the regulations for VOC. The pergola is very intricate and large so I'd be interested in the longest lasting product. Would the 100 or 1500 series product be the better choice?

    Use the 100 Series. and since it is all rough cut, you can go ahead and stain now.

    I am ready to re-stain a 16-year old house that has cedar horizontal siding, located in the Pacific Northwest (Lynden, Washington), where the summer is hot and dry and the winter is wet, with very high humidity. I have been treating the siding for mold and mildew and now have it lightened up again. My concern is that I do not want the black spots of mildew to return. Which product will best protect against mildew re-growing, and will protect the cedar against rain and moisture?

    Use the TWP 100 Series for this.

    I am replacing the deck on my covered porch. It will be 2x4 redwood kiln dried layer on edge due to span between joists. The decking boards are 18' long and are going milled from rough 2x4.
    There will be some exposure to water and some sun at the south facing end of the deck since the roof overhang is not sufficient to prevent driven rain.
    I am in Los Angeles area and would like to use semi transparent gray color. Preferably oil based. What do you recommend and where can I purchase it. I will pre-stain all sides before installation.

    I am sorry but you can only use the 1500 Series in CA and it does not come in a gray color.

    Boathouse deck, pressure treated 5/4, 6 years old. Previous stain has worn off and deck is slightly grayiing. It is exposed to intense sun. Which stain is the best to use and which color most closely resembles new pressure treated wood? Many thanks.

    Look at the 1500 Series for this after prepping with the Gemini Restore Kit. Honeytone is the lightest tint.

    Is the TWP 1500 suitable for outdoor furniture. I have a new cypress swing coming and am wondering if this product will work on it.

    Yes it will work on wood furniture.
