Works fine people
Your wood should be dry (ish) - this sealant will not stay tacky, you just need patients, let it dry abit. I used this all around our pool. The deck is nice natural greyed up wood (old, sun beat and reused 1 million times) and it did take an hour or so to dry ( in the hot sun) but after that, no prob, beads water off awesome! BTW, totally went swimming cuz forgot I sealed the decking bout hour and a 1/2 in, didn't matter tho the sealant was already dry. You can look @ the pictures - see the results?.. ch,..good stuff A. *been about two weeks and beaded-er-ing great*

Same Price, Less Hassle!
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 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.

Works exactly as advertised—reliable waterproofing
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.

Easy to apply, your wood will get a little darker.
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.

Old product I assume
When receiving item, the can was bent half way itself. The one can was in a huge box, so I didn’t understand why was the can bent so bad, the box perfectly shaped. And when open the can it looked like sour milk. Went ahead any shakes it up. Really good, and it still poured out clumps, used it anyway, and I should not of have. My deck been sticky for days now

Great for protecting wood decks, porches, and balconies
This is an excellent product. I bought it for the wood on my balcony, and it did a great job of protecting it against the rain. It's also very easy to apply. It does have a white consistency when first applied, however it turns clear when it dries.

Good product
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).
