★★★★★
“Perfect for a small concrete crack.”
Our walkway had a crack that collected water every time it rained. Easy to apply and the repaired area looks much better.
★★★★★
“Fixed the problem area near the roof edge.”
Rainwater kept getting into a small seam near the roof. The spray made it much easier to cover the whole gap.
★★★★★
“Great for sealing around pipes.”
There was an ugly gap where one of our pipes goes through the wall. Covered the entire gap without needing a bunch of tools.
★★★★★
“Much cleaner around the wall corner now.”
We had an outside corner with cracking and dark moisture marks. After sealing the area, it looks dramatically cleaner.
★★★★★
“Exactly what I needed for the gutter seam.”
One section of the gutter had a seam that dripped during heavy rain. This was a much simpler fix for such a small problem.
