VOC (Volatile organic compounds) regulations are changing rapidly across the USA and Canada. Not all of the stains that we sell are compliant for all areas. As it stands 16 US states and Canada have adopted the more stringent 250 regulation:

TWP 100 Series and TWP Semi-Solid Pro-Series is not VOC Compliant for Canada and these USA states and cannot be shipped or used there: California, Colorado, Connecticut, Rhode Island, Maine, Massachusetts, New Hampshire, Vermont, Delaware, District of Columbia, Maryland, New Jersey, New York, Northern VA, Pennsylvania, Parts of Arizona, Ohio, Illinois, Indiana, all of Canada.

TWP 1500 Series is compliant for all 50 States but cannot be shipped or used in Canada.

TWP 200 Series is compliant for all 50 States and Canada.

    We want to refinish an OLD gray composite deck.  Want to do it in a gray color.  We are in OH.  Which product should we use in grey. I'm confused.

      Sorry but we do not have a product that can be used on composite and that is allowed in Ohio.

    I rebuilt a back deck a couple of years ago with pressure treated lumber.  The deck gets full sun in the summer - from 9 am till 8 pm, which series should I use?  Zip code 35645

    In the summer of 2017 I built a fence. Waited a few weeks and stained it with TWP 100. I re-applied TWP 100 in 2018 and 2020.

    This fence gets a lot of UV (SW facing, high altitude). Little precipitation but does get wet from irrigation. I was hoping to go two years before reapplying but the wood does seem to be 'drying out' and where irrigation water hits it, it's getting gray. But it doesn't peel which is great.

    I'm looking to re-apply this spring and am wondering what my best choice is.

    Should switch to Semi-Solid? If I do, do I need to strip it first? Can I switch back to TWP 100 or then do I have to strip it? Does the semi-solid start to peel? Should I just stick with TWP 100?

    Thanks,
    -R

      If you switch to semi-solid then yes, strip and brighten for prep. Same if you switch back to the 100 Series. The semi-solids do not peel. You will have better UV protection from fading with the semi-solids. Can you adjust your sprinklers to not hit the fence? That would help.

      The 1500 Series is not made in a gray color and cannot be.

    I live in the Pacific Northwest, Seattle area, and have three connecting cedar decks that we stain with Super Deck red cedar transparent oil stain. We have used that product on the decks for 20 years. We usually stain horizontal surfaces every two years and the railings every 4. Apparently Duck Back, the makers of Super Deck is no longer making an oil based product, so we are looking for something similar without having to remove the old stain. It would be very difficult, with railings all around and large surfaces. Do I understand that your 1500 product is oil based, and can it be used over the existing oil stain? We will be lightly pressure washing the decks and scrubbing the horizontal surfaces, as we usually do, before applying the stain.

    We have a marine plywood clad garage that originally was finished with Sikkens Cetol (clear) but exposure and poor initial application has resulted in pretty faded/worn/ugly cladding.  The marine ply now has a rough surface but cannot be sanded since there won't be any thing left if we do!  Can we use the 100 series in a color over the old Cetol surface?  What prep would be needed?  We are in Seattle area.  Thanks!

    I live in Western NY where the wind literally scrapes the snow across our wood deck and removes the semi-transparent stain I've been using - thus requiring an annual re-application.    The previous semi-transparent stain was Olympic Maximum. Which cleaning kit would be recommended before applying the recommended TWP series? Would I be better off with the 1500 series or the Pro?  And do they both destroy mildew?   Thanks.

    What series is TWF Shake and Vertical Surface Sealant and what happens if you use it on a deck, since I just bought (still unopened) this for my deck?
    • We will reply to your comment shortly
      TWP Stains · 03/21/2022
      We responded to your questions earlier. It is below. 

      It is not suggested for decks as it cant take many days to dry and cure.

    We used TWP shake and surface sealant on our deck 2-3 years ago.  I accidentally bought TWP Shake and vertical surface sealant recently.  Are both OK for our deck?  Any trouble using the latter over the former?  Any preferences between them?  Which series is each of these in?  Thanks.

      Thre is only one version of TWP for shakes and shingles and that is the 200 Series. There has never been a separate version just for decks.

    Is TWP acceptable for a grill table?  We have two BGE smokers and would like to match the stained floors.  If not, what stains have similar color to TWP?

      Yes. Make sure the wood is prepped correctly.

    • We will reply to your comment shortly
      TWP Stains · 12/29/2021
      If you want to use a respirator, then make sure it is one that is rated for oil-based products.

    What is the difference between your semi-solid and semi-transparent stains?   And where is that state list for compliance.  Missouri and Ill is of interest..   thanks    
    • We will reply to your comment shortly
      TWP Stains · 11/17/2021
      The state lists is above on this page. Difference is that the semi solids has higher solid content of color and will give better UV protection.

    I am in zip code 82633 and can use TWP 100. Would that still be preferable to TWP 1500 or 200?? Why? I am using it on a rough cut cedar pergola. Thank you!

      You can use the 100 Series in WY. Any of the series would work equally well for your area and your rough sawn wood.
