### ⭐⭐⭐⭐⭐ Best roof and siding sealant ever
*by G***. on November 27, 2025*

If you are doing roof work or siding work. This will seal forever. Best stuff I’ve ever found.

### ⭐⭐⭐⭐⭐ Dries very quickly
*by D***N on January 9, 2026*

Excellent product .

### ⭐⭐⭐⭐⭐ Best stuff ever!
*by G***A on July 3, 2025*

I’m giving a five star because the batch I received has a 8 month shelf life and the previous two batches also had a long shelf life, which seems to be rare when it comes to Sikaflex. Sikaflex 1a is the best stuff you can get. It works on everything.. Don’t use it on something you plan on taking apart later lol it’s permanent stuff. If you’ve never tried it, you must get some because every contractor and handyman should have this product in their arsenal. It works great on concrete, wood, roofs, and almost everything else.
