Invisible Waterproof Agent Transparent Repairing Leak Waterproof Adhesive for Roofs, Walls, Bathroom, Shower, Window Sills, Indoor & Outdoor Water Proof Coating 35 Oz

This invisible waterproof agent really works. I used it on the deck's wood railing; it created a strong, water-repellent barrier without changing the appearance. It dries completely clear, leaving no sticky residue or discoloration—you can’t tell it’s there, but it works!Water now beads right off the treated surfaces, and it’s been holding up great even in heavy rain.

Make sure it warms up by letting it sit in the sun for a few hours. It then spreads easily with good coverage. Flows into any cracks. So far no leaks after several heavy rainstorms

Clear and effective. Had two windows that seem to allow hot air during the summer and cold air during the winter. Haven't felt any airflow since applying this. Therefore id say it works well because I didn't even have to use a 2nd coating.

Pensé que no servía porque tarda mucho en secar, pero cumplió su objetivo

This is what I needed for my outdoor crafts and decor . It’s clear and thick but dries thin and completely transparent like an invisible protective layer and so quick . It goes along way . I would definitely purchase again .

I used this to waterproof a painted birdbath. I carefully followed instructions and allowed 24+ hours between 3 coats and allowed a week before filling with water. (July heat in FL so it was warm enough). The colored paint turned milky white where the water stands. This is not my main complaint though. Each time I used the product with a brush it made my hands and forearms itch quite a bit with absolutely no contact with the product. To date I have raked leaves from the water in the birdbath with my fingers a number of times and just getting my hands wet it makes me itch for some time. Makes me wonder what it contains. I work with my hands and haven't suffered any lingering reactions to chemicals like this. Haven't seen any birds come near either.

They have a newer version that is $5 less. Check my photo that includes a measuring device. Know what you are buying. They are not deceptive—just look and read carefully. Haven’t tried sealing up my shower base crack yet. Can only hope…..
