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 is not VOC Compliant for Canada and these USA states and cannot be shipped or used there: California, 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.

    I have a 12’ x 12 ‘ 28 yr old red cedar deck. I am replacing 9 boards. I live in DC. The TWP 100 Series is outlawed here. Should I use the 1500 in Pecan? Years ago I used one of the stains. It’s a red cedar color. Don’t know what it was. I have 13 spiral steps.

      Yes, you would want the TWP 1500 Series for this. You will need to remove the current stain first.

    I am planning to stain a newly installed fence (deck wood). How long do you recommend before staining? I will also be doing our large deck. It has a well worn stain if some sort already, from the previous homeowners. What prep is needed for the deck? Finally, do you recommend the 100 or 1500 for northern Virginia? Thanks!

    Love your product. Have now stained my cedar deck 3 times every 2-3 years using the TWP 100 series Dark Oak color, using cleaner/brightener each time. The deck is gradually becoming quite dark in color. Can I use Clear next time, or perhaps mix Clear with Dark Oak to lessen the color? Clear info states "no UV protection" -- is that important? Maybe switch to Pecan or a lighter color? Your advice?

    Have dry hemp fir or doug fir hand hewn beams and support carved posts coming to Sa Juan County, UT in a month or so. Should I put up and let sit till spring? Will they turn gray? I do not want gray as the natural wood color is important to us. Should I get the 100 series or the 1500 series? Will the clear allow the wood to turn gray or should I get the lightest stain color? Thanks so much.

      Yes, install and wait until Spring to prep and stain. The prep will remove any gray. Use the 1500 Series. Clear will gray naturally.

    Are any other colors available in TWP 1500; such as the TWP 100 colors? Are special colors possible?

      Sorry but no other color options and no special colors can be made.

    Hi, I stained my new deck last fall with TWP 100 with wet on wet. I was unable to treat again this spring, but I'm ready to do it now. I will use cleaner/brightener first, bust as far as staining goes, do you recommend 2 coats wet on wet again or should I use just one coat? I feel like I should do wet on wet again.

      If you have a base coat after prep, then just do one coat.

    I'm reading your site - it's very helpful - but I'm not sure I understand the difference between the 100 series and the 1500 series. I live in western NC. Does that make a difference?

    I live in AZ (zip 85234) where I hope to receive shipment, but plan to use TWP 100 in cabin in Utah. Noting TWP 100 cannot be shipped to "parts of AZ", can it be shipped to the AZ 85234 zipcode?
    Thanks

    If I use 100 series and Nebraska later changes it’s VOC restrictions, could I apply the 1500 series over it without stripping?

      Yes, but they will not change anytime soon.

    Hi-We are building a redwood fence in California. It is kiln-dried. What prep (besides sanding) is needed and how long to wait before staining? Thanks!

    I will be putting on kiln dried rustic channel shiplap for siding. We live in Mts of Northern VT. w/ 5 months of winter snow on the ground. The back side of the siding is planed smooth. The front / exposed side is rough cut except the 1 inch channel is planed smooth. To prevent cupping I was going to one coat the backside w/ TWP 1500 fairly soon after delivery then put the siding up if this is ok. I realize rough cut can be done right away, but can the channel also be done then or should I wait to the following May or June? Would prefer putting up siding this year if possible.

      Best to install, wait for a month or two (for kiln dried wood), prep with the Gemini Restore Kit, then stain. No need to stain the backside not would it prevent cupping.

    Hey there, we have a cottage with a 9 year old massive pressure treated deck facing West in Northeast Michigan. Lots of sun and snow. We’ve used TWP 100 twice to stain it. So far so good. It’s aging gracefully. Thank you for a product that actually lasts more than one year. Before we embark on our next loving journey into staining this thing, I was wondering if we should switch to the 1500 series this round? Regards,

      No need or advantage. Stick with the 100 Series.

    I have a 40 year old cedar log house to exterior re-hab in Northern Va. After sealing the joints and cleaning the exterior walls, which is better, TWP101 or TWP1501? The climate is humid in the summer. Thx.

      DocH · 05/08/2019
      Edit: I see now that TWP101 is not shipped to N.Va. So how does the humid climate here affect the drying time of TWP1501?

        No issues, it dries like the 100 Series.

      Use the TWP 1500 series.

    I really like TWP 100 and I've have been buying it in 5 gallons. I'm in Washington State,so free shipping is important. With 5 gallons I've been able to maintain my deck for 2 yrs
    However on my last 5 gallons when I stir'd the TWP for the second year the bottom of the container had solidified compounds. I do seal the container and stow it in the packaging it came in. Is this occurring because I'm using 100 ?

      The shelf life of an opened container is 12 months, that is why this is happening.

    I’m in Ohio. Installed cedar privacy fence in late fall. Too cold to stain. I will use a semitransparent stain. Boards are rough to touch with splinter chances so assume it’s rough sawed. Fence is clean, no gray or stains. Looks brand new. Do I need to clean it first before staining? It is a very long fence so I’m trying to be efficient with my time. Also 2 coats now- wet on wet or 1 coat now and 1 in a year? I’ve read both. If 2nd coat in a year do I need to use cleaner/Brightener before second coat if the fence still looks as good color and dirt wise? Thank you

      No need to prep new rough sawn wood as long as it clean. 2 coats wet on wet for this since it is rough sawn.

    I just built a patio cover out of cypress cut 2 months ago and planed the rough cut. Want to keep it as close as possible to natural color and keep from aging grey. Can I stain it now or do I have to wait and which product is best in Louisiana?

    what is the difference between 1500 and 100 in terms of coating performance such as mildew resistance and coating lifespan.
    • We will reply to your comment shortly
      TWP Stains · 04/07/2019
      No difference. They will perform the same.

    We are in NW Georgia and have a large deck around an above ground pool. Deck is 3 years old and had Thompson water seal 2 years ago. Will TWP work well with a lot of exposure to water 3-4 months out of the year? (Small children continuously getting in/out of pool!). Which TWP product will work best?

      TWP Stains · 04/02/2019
      Hello,

      No deck stain can withstand chlorine from the pool water for a lengthy time but the TWP will easily outperform the Thompsons.

      Use the TWP 100 Series.
