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'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

    For a 6-month-old pressure treated pine deck in Charlotte, NC, what do you recommend:
    1) 100 or 1500 series?
    2) How and when to prep and treat?

    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.

    I have a 15 year old wood deck in Michigan. Just pressure washed and sanded. Trying to get the most natural look out of the wood with UV protection. What series and color should I use.

      Try the TWP 115 Honeytone for the lightest tinted color.

    My last contractor used 1500 series (4 years ago). Is it ok to put 100 series on top of that?

    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.

    My CEDAR deck is over 20 years old [approx. 400SF of flat surface]. It was professionally treated with TWP #101 in 2017 and needs to be refreshed. I plan to do a non-pressure wash with a cleaner and then reapply TWP 101. 1] where can I buy TWP 101 in SE Michigan? 2] what kind of coverage can I expect from a 5 gallon container?

    I live in upstate NY and want to finish a rough cut pine board and batten vertical sided structure -should I use the 100 or the 1500 product?
    I used the 100 product for the deck railings made out of ash but the wood is too dense for it to penetrate well and it needs to be done every 2 years.
    I really don't want to have to re-stain very few years on the structure.

      TWP Stains · 07/17/2019
      For NY, you need the 1500 Series. For vertical wood, you should get 3-5 years.

    I have a 3 year old redwood deck. A sealer only when installed. 2 years ago an oil based sealer with no stain. I power washed it twice. See the photos. I want to stain/seal with semi transparent redwood stain. Or should I go darker? Should I use a wood brightener first? Or should I power wash it again? Can I go with series 1502 for this. The deck is approximately 13' by 30'. And what does wet on wet mean? Do I do in sections or do the whole deck and then reapply a second coat? How long should I wait between applications?

    What would be the best stain for a shady cedar deck in Saint Paul, Minnesota? It was stained with TWP about 4 years ago and I think it was the 100 series. Lots of foot traffic so some areas were worn down so we have cleaned and stripped the whole floor of the deck but the spindles and railing should just need a light coat. Thanks!

    what exactly do you mean by the term wet-on-wet. It will take at least 4 hours putting first coat on, does this mean I cant wait until 24 hours to apply second coat?
