This worked extremely well to seal cracks in my stucco.

### ⭐⭐⭐⭐⭐ Works great!
*by T***E on September 17, 2024*

Covers well, drys fast, looks good

### ⭐⭐⭐⭐ Pretty decent for tired houses
*by R***. on May 21, 2024*

I have a crazy room that defies description and had leaks so I put out 4 cans. I think I'm down to one leak. Also works great on tired wood that won't hold paint. I'm old and getting tired. A bit thinner than I thought. I definitely wore safety glasses and old clothes in case wind blew it around.
