Real Customer Reviews
Saved me a handyman call.
I used it around a small window leak. Brushed it on, let it dry, and it looks way cleaner than I expected.
Clear finish is the best part.
I did not want a big ugly patch showing. It dried clear and blended better than the white sealant I used before.
Easy to use with the brush.
No special tools. I cleaned the area, brushed it over a crack near the patio, and added a second coat the next day.
Good for small repairs.
I would not use it for a major plumbing issue, but for small cracks and leak-prone edges it is very handy.
Kept it in my tool drawer.
Used it once and decided to keep the rest around. It is one of those things you are glad to have when a little leak shows up.
Much neater than caulk.
I used it on a small gap around tile. It was easier to apply neatly than regular caulk and did not make the area look messy.
