Crack in concrete.

Cracks in concrete surfaces, such as driveways and patios, need to be sealed to prevent erosion and further deterioration.

QUIKRETE Polyurethane Concrete Crack Sealant is perfect for this job, since it matches the color and texture of concrete and remains flexible after it dries.

VIDEO TRANSCRIPT
Concrete is pretty resilient stuff, but cracks in a finished slab can lead to erosion and deterioration. Fill those cracks quickly with a Polyurethane Crack Sealant to prevent further damage from water and ice.

The sealant should stick well without sagging, but a good one will also be textured to blend in with the adjacent concrete surface. It should also remain flexible after it dries so it doesn’t crack as the slab expands and contracts.

  1. excuse me. i am korean univercity student who major in polymerengineering. i’m studying now about polyurethane so i want to know your polyurethane sealant component. what monomer is used? what isocyanoate and what polyol was used? thank you

  2. I was planning to use a urethane fiber glass on an inside wall. I am trying to avoid having to remove stucco from outside. Windows were installed improperly & water leaked in & caused rotting wood about 15 ft. under large window. Windows are being replaced. It is impossible in my area to hire a professional so I am left to fix it myself. Applied a small amt. & odor is repulsive. Even if odor eventually goes away(how long does it take?)is it safe for people & animals to breathe in?
    Thanks so much for any help you can give me. Bill

    • Hi, Bill,
      Danny says, “The odor will dissipate but you can accelerate it by having a fan blowing in the area and introduce as much fresh air into the room as possible. It won’t take long before it goes away.
      Good luck!”

  3. I have a expansion joint crack I would like to fill and this looks like it might do the job. My concern is, will it stick to the concrete since I have a water based concrete sealer on it?
