As expected, no big surprises

Sealed as described, but it did take a very long time to cure.

Concrete sealer

Would Recommend

This product is awesome to seal cracks in your concrete! It’s flexible and after 5 years it’s still looking good. It’s easy to apply using a caulk gun. It seals out water to prevent the damage caused by winters freezing thawing cycles!

Water proof

[This review was collected as part of a promotion.] This polyurethane sealant is okay. It adhere to the cracks in driveway by filling them in. It only takes a few days to cure then its water proof. My only issue with it is the sealant is very thick. It requires alot of hand strength to use.

Sidewalk repair

[This review was collected as part of a promotion.] Another quality product from a brand you know and trust. I used this for a small sidewalk repair. Easy to use, quick to cure, and has lasted thus far (1 month).

Good product

[This review was collected as part of a promotion.] The application process is straightforward and with a regular caulk gun. It is a little thick need a little more steady hand and pressure to apply.

Great product!

[This review was collected as part of a promotion.] Great product! I did an addition on my home and needed some sealant to fix a few spots and this stuff works great! It fits in a normal caulk gun and the workability is great! I was able to spread the product with a putty knife in some places as well with ease!
