Thompson’s WaterSeal Multi-Surface Waterproofer Stain, Clear, 1 Gallon

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

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.

Thompson's WaterSeal Multi-Surface Waterproofer Stain in the convenient 12 oz aerosol can is a game-changer for anyone looking to protect and enhance the beauty of their outdoor surfaces. I recently used this product on my wooden deck, and the results exceeded my expectations. First and foremost, the ease of application is worth highlighting. The aerosol can provides a consistent and smooth spray, ensuring even coverage. It saved me time and effort compared to traditional brush or roller application methods. The clear stain is a fantastic choice as it enhances the natural beauty of the wood while providing a robust waterproofing barrier. Rainwater now beads up and rolls off, keeping my deck protected from moisture damage. I was pleasantly surprised by the durability of this product. It has been several months since I applied it, and the finish still looks as good as new. The UV-resistant formula ensures that it doesn't fade or peel under the sun's harsh rays. Cleanup is a breeze with soap and water, making maintenance hassle-free. In conclusion, Thompson's WaterSeal Multi-Surface Waterproofer Stain is a top-tier product that combines ease of use, durability, and protection for your outdoor surfaces. Whether it's a deck, patio, or other wooden structures, this product enhances their longevity and appearance. I highly recommend it to anyone looking for a clear waterproofer stain that delivers on its promises!

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.

Yes, you can grab this at your local store for the same cost—but when you're juggling a project schedule, the convenience of having it shipped straight to your door is worth gold. I ordered mine ahead of an upcoming job, and it arrived fast and damage-free. Why it delivers (literally): Works great on wood, brick, concrete, and masonry—perfect for decks, furniture, and small outdoor projects. Clear finish enhances natural material grain while giving long-lasting water protection. Same price as in-store, but saved me the time, gas, and impulse buys. Helpful Project Tip: Shake or stir thoroughly before application, and use a clean brush or low-pressure sprayer. Let dry for 24 hours, and avoid working in direct sun or on super hot days—it’ll help the seal bond evenly.

I have a concrete garden statue that I waterproofed with this product. Works great, water rolls right off. Make sure you apply when it is not too cold outside.

Great product works better than the competition. Big surprised Amazon didn't loose my order

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.

I have used this product for years. Love this for all my natural outdoor wood. Deck, fences, table and planters. I just sanded my fence from, an ugly chipped brown paint and love the rustic look when I covered it with the Thompson’s Water Seal.

I have used it for wood as well as for concrete. For now it is not fading.
