Which TWP Deck Stain is Best for You?

TWP offers several different stain formulas for superior wood protection. All are blended using the best in raw materials and remain the only EPA registered wood preservative. All TWP Series Stains offer maximum wood protection and enhanced beauty for a long lasting durable finish.

TWP 100 Series – The 100 Series formula is the original preservative and has remained a leading formula for over 25 years. It penetrates better over the 1500 Series and comes in 8 different color tones. It blocks out damaging UV rays keeping the wood from fading and has outstanding water shedding capabilities. It dries faster than the 1500 Series and has a faster absorption rate.

 TWP 100 does have a higher VOC level and cannot be shipped to some states (check availability). Where available, 100 Series is a great choice for any exterior wood project. It absorbs into wood extraordinarily well for maximum protection and gives a long lasting finish. It is not prone to mold or mildew. It is best used on wood decks, fences, siding, and hardwoods.

TWP 1500 Series – The 1500 Series Stain is a low VOC blend that is compliant in all 50 states and comes in 9 different tones. It is designed to outperform the former 500 Series blend and is also an EPA registered wood preservative. The TWP 1500 provides higher UV protection than the 100 Series.

The 1500 Series is user-friendly and easy to maintain. It enhances the wood’s beauty and prolongs the life of all exterior wood surfaces. The absorption rate is a bit slower than the 100 Series but dries in 4-12 hours on average. Both the 100 and 1500 Series Stains are 1-2 coat applications depending on the age and porosity of the wood. They are best applied using two light coats “wet on wet”.

    I also live in Michigan. We have a Cedar home that was protected about 16 years ago, but just recently cleaned and the wood looks great. Its a Semi-sunny/ shady area. Would I use TWP 100 or 1500? Oil/water based? Thanks!

      Use the TWP 100. Both are oil-based.

        Why did you recommend the 100 series instead of the 1500 series? I assume because the home does not get much sun. Thanks!

          The 100 Series is what everyone in MI uses on their decks.

    I live in Michigan. Have a deck that is roughly 25 years old and doesn’t look like it’s ever been stained. I am going to power wash it this weekend and sand it. What products should I use to stain?

    Hello
    About to strip and stain my first deck, and TWP was recommended to me.
    I live in Minnesota and was wondering which product (1500 or 100) would work best with our cold seasons and drastic temperature changes?

    Stained brand new deck with Armstrong and Clark last summer. Looked beautiful. In 4-6 months wood developed dark black residue which I was told by AC was mod/mildew. Very disappointing.
    I want to try and apply TWP stain this year. Will clean and dry first.
    Which series is better 100 or 1500 to prevent mold/discoloration. I live in NJ.

    I'm constructing a rustic pergola from unmilled Eastern Red Cedar logs. Would 100 Series or 1500 Series be better for this application? Thanks in advance.

    I'm a contractor in South Carolina. I work exclusively in one neighborhood on a lake. Wood rot is very common in these older homes built in the 70s and 80s, with cedar siding and wood decks.
    I'm rebuilding a 40 year old deck that is 2000 sq ft.
    Surrounded by large trees and has 2 drainage ditches. One part of the deck is built over the ditch. Lots of moisture.
    I'm suggesting to the customer to use TWP 100 on the new pressure treated decking. After it sets for a few months.
    Question? Can I apply the stain to the underside of the decking and the deck framing, to help it last longer in this moist environment?
    The old deck was completely rotten and literally falling apart. The worst I've ever seen.
    Thanks for your suggestions.

    About to put up a new pergola of western red cedar in northeast Texas where temps often exceed 100 degrees in summer. Temperature at time of application though will probably aerage 50 degrees. We've been happy with TWP 100 but client likes black walnut color which appears to only be available in 1500. Any advice you can provide would be appreciated.

    Help! Cypress covered porch south facing western NC. TWP 100 pecan. Prepping for our 3rd application in 6 or so years. Used Gemini steps 1&2. Hand cleaned with a brush and hose. Two questions: How to even color across the width? What to do with this uneven/bubble spot? Several of these on the interior protected portion of porch floor. Thanks! Rebecca

    I used TWP 100 for my deck and liked it so much i used it to seal and stain my knotty pine T&G soffet and ceiling on a high end woodshop I built this summer. I am thinking of getting more to use on my exterior doors I am making from white oak. For greater long term protection, I think I need to top coat the stain with a Spar Varnish. Is this advisable? Will the TWP adhere to the Varnish?
    thanks

      You cannot topcoat TWP with a varnish, it will peel.

    After several years, we are finally getting the TWP 120 that we previously purchased applied to our 600 feet of raw redwood fence. The project is nearly done, and looking good.

    However, we have now learned that Colorado is tightening up its VOC regulations to be more like those of California. (We don't know the exact terms of the new rules, but expect the worst.)

    Anticipating that we'll need to do more maintenance in a few years, is your 1500 series compatible with the 100 series? Or, would it be better to "stockpile" some 120 for that eventuality to be certain of success.

      You can clean and recoat with the TWP 1500 if needed at a later date.

    I have to reapply stain to my grandmas deck in the coming weeks. I have the contractors invoice from 4 years ago stating it used "gemini" Natural Cedar. I assume its TWP. But I am not sure which one to get, TWP 100 or TWP 1500. Does it matter? I'm trying to avoid stripping the entire deck.

      TWP does not come in "Natural Cedar" but the TWP 101 is called Cedartone Natural on the label so most likely that is what they used.
