    • Phenomenal sealant!!
Size: 10-Ounce Style: Cartridge
Excellent product for concrete repair. You can apply it to wet surfaces or concrete that hasn't cured. This has an elastic bonding property that will allow it to fill and also flex when hot or cold.

    • Seals Well
Size: 10-Ounce Style: Cartridge
Used this for my stress risers in my concrete garage floor that have cracked and allow moisture into my garage from under the floor. It is self-leveling and does a nice job. Just make sure to clean the grooves first and use a good caulking gun. No more moisture on the humid days on my garage floor which used to be very slippery when it happened. ... show more

    • SIKA makes good concrete sealants
Size: 10-Ounce Style: Cartridge
This and SIKA’s self leveling sealant both work very well to seal cracks in concrete. I found this easier to work with for thinner cracks than the self leveling sealant, since it is easier to control and stop the flow when not in use. The self leveling version works best when the entire caulk tip fits into the crack and the “flow” of the sealant can spread out into the crack and self level without making a mess. My only complaint is that the limestone color is really a light gray. It’s pretty much the same as the self leveling gray color and doesn’t blend perfectly with the limestone color of most concrete. For this, I would give it 4.5 stars. Tip: A little sand sprinkled and rubbed in after application helps it blend better with the concrete texture and color. ... show more
