I am a DIY person whenever I can save money. I live in Florida and have a boat dock in my back yard. Every 2-3 years I power wash the entire deck and seal the wood decking. I saw negative reviews about this product with previous customers claiming the product was milky and did not apply well. Some thought the product was bad. I can tell you I bought 2 cans of this product because I trust the brand name Thompson’s Water Seal. Yes, the product was a milky consistency coming out of the can. I used a pressure sprayer to spread the product. It applied milky, but quickly penetrated the wood decking and dried clear, giving my boat dock a beautiful finish. I don’t understand the reviews complaining about the product. I am a very satisfied customer and will use this waterproofing sealer again. Well worth the cost and the brand did not disappoint.

I love this stuff. If your wood is dry it absolutely soaks this up like a sponge and then you are waterproof. It seems to be non-toxic to plants, I got it all over my lawn painting my fence and the grass did not seem to care.

Thompson’s WaterSeal Multi-Surface Waterproofer does exactly what it’s supposed to. I used the clear 1-gallon version for a deck and concrete walkway, and both surfaces repelled water almost instantly after drying. Application was simple with a pump sprayer, and cleanup was easy. It dries clear with no residue or discoloration. This is a dependable choice for protecting wood, brick, concrete, and more from moisture damage. No complaints—just solid results. Q&A Section: Q: How long does it take to dry? A: It dries to the touch in about 2 hours, fully cured in 24–48 hours depending on humidity. Q: Can it be used on concrete and wood? A: Yes, it’s designed for multi-surface use, including wood, concrete, and brick. Q: Does it change the color of the surface? A: No—it dries completely clear with no visible sheen or color change. Q: How long does the water protection last? A: Protection typically lasts up to a year, depending on exposure and surface type.

This will seal ANYTHING. It's good as a final top coat because it's a thin penetrating liquid.

I need to buy more and reapply but lasted about 1 1/2 years on a chicken coop exterior. We get all seasons. Value for price. Easy to use.

Great quality, nothing sticky. Went on smoothly and dried quickly. Very happy.

Used the entire gallon to coat a floor of a shed that was under construction. We had heavy rains over the next few weeks before we could put up walls and roof. Water did not bead up as I expected. Can't tell how well the wood which is treated will be protected in the long run. Time will tell. I have used this product in the past and was very happy with how long the exposed wood lasted, so this may be a perception problem on my part. I'll give a follow up as I learn more.

Works well, drys clear even though it’s a milky colour . Clean up with water though it seems to leave a slight residue on the brush, also gives of a slight odour so best to use in an open environment ( open garage door etc).

Works great. Can’t change to anything other than this on the same wood.

Good product

Sachez qu'il s'agit de la version à l'huile qui demande presque 3 jours à sécher. Ce lot provient du sud des USA car l'étiquette n'est qu'en anglais et espagnol.
