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 have a new deck that is 2 years old and
    and has never been treated. What product should I use and can I just power wash or
    should I use a cleaner? I live in Wisconsin

    You need to use the Gemini Restore Kit with the prep and use the TWP 100 Series.

    I've a home on the Texas coast. The roof overhangs the cedar wrap-around porch. The pool deck is exposed as are the lower floor vertical pillars. The old PPG alkyl stain has failed miserably after 7 yrs. What product is best for this application.
    Thanks, Patrice

    Use the 100 Series. Prep well to remove the PPG stain first.

    Have redwood 12' x 40' deck, used Penafin oil on all surfaces five years ago. Deck is now darkly discoloring. We would like to use a product that will retain the lighter wood tones. Which TWP item do you recommend, and approx. quantity please. We're in California.
    Thank You
    Michael Higdon

    Please use our calculator on the right side of this page to determine amount needed. You will need to strip and brighten for the prep. Use the 1500 Series for CA. Honeytone is the lightest.

    Last year we sealed and stained our log cabin in northern Wisconsin. It was raw pine and we used the 1500 series. My question is how long will it last before I have to do it again.

    Vertical wood on a log cabin can last 3-6 years depending on the exposure to the sun.

    Craig Peterson:
    I have a 20 year old pressure treated pine deck in central Illinois. Part surrounds an inground, seldom used pool. Over the years it had been previously cleaned and restained annually with Penofin. The last time the deck was treated was 6 years ago, I used a stripper and applied Woodsman Premium Translucent Oil Stain. The color lasted about 2 years. Penofin never lasted more than 1 year. Last week I powerwashed it to remove considerable mildew and algae. The wood cleaned up well with that alone but I probably left tiny areas of mildew/algae behind. What would you recommend I do as per further cleaning and stain?

    If still have the old stain on the deck then you need to remove it with the Restore A Deck stripper followed by the RAD Brightener. If not, then use the Gemini Restore Kit for the prep.
