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.

      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.

    Soon we will have sanded-and-brightened old wavy cedar siding, facing south in Florida, ready to stain, with all-day sun to consider.  Picture attached.  Am I right in thinking that not only would the Semi-Solid Pro Series be more protective than the 100 but a darker color in the Pro would give the wood even more protection?

      No need to sand. Strip and brighen for prep. The semi-solid will give better Uv protection than the 100 Series. Any color will work.

        1.  Does the deep penetration of 100 "make up" for having less UV protection than the semi-solid? 2.   The 100 has some UV protection in it anyway, doesn't it?

    I just installed a new pressure treated pine split rail fence. It’s rough cut and very dry or “thirsty.” How long should I wait? Thanks

      You can stain right away since it is rough sawn cut.

    I live in St. Louis, Missouri and have a new cedar wood deck.  Should I use TWP1500 series or TWP100 series on new wood, which is better and why?

    Just finished sanding all of a Solid Stain, don't know what product.  An am looking to purchase, but am looking for clarification for future use and what I might buy. 
    Can a TWP Semi-solid stained deck be re-stained with the same TWP semi-solid stain without stripping off all the old TWP if you use the cleaner and brightner products?  Or must you remove all the semi-solid stain completely? 
    Same with the Regular TWP Stain (not semi-solid), does it need to be completely removed if applying the same product if using the cleaner and brightner?

      Yes, you can clean and recoat the semi-solid colors as needed without having to sand. All TWP stains are like this.

        So, just to be accurate, in a couple years we can simply use your cleaner on top of the deck then re-apply same TWP. Since not down to the bare wood, no need for brightner.

    I used TWP-100 on one year old pressure treated deck boards in 2015 (unfortunately we were moving and had to get it done). We moved back and after six years of heavy sun exposure it's in bad shape and needs to be re-done. How do I best prep these boards for another coat of TWP-100?

    I am installing PT pine deck posts with composite decking. Will use Genesis restore before staining after pine dries maybe 4-6 months later. Will the Genesis restore or cleaner discolor the composite decking if it gets on it? The decking is Fiberon armourguard. Thanks.

      No, the Gemini Kit will not harm the composite but do rinse well with water when done to avoid dirt etc from drying on the composite.
