Hey, one thing’s for sure; if you have concrete, it’s going to crack, and you need to repair those cracks for a lot of different reasons. The problem is a lot of the material you use to fill those cracks will either crack again or will be really shiny and won’t quite blend in.

Well, here’s what you need to use. This is brand new from Quikrete, and it’s a polyurethane concrete crack repair. And it’s a textured type of material, so it looks a lot like concrete. And the real advantage is it’s flexible, so you won’t have those cracks again.

And the exact same type of material is available for bricks, so that it looks just like mortar. And again, it’s flexible and just won’t crack.


  1. Do you or anyone make a patching compound that is red brick colored for patching red brick (obviously)? A conduit that went thru the brick, was removed on the outside of my home leaving a hole in the brick approx. 1 inch in diameter. I can patch it with your concrete colored caulking, but because of the size, I was hoping you made something red brick colored so it blends in better.

  2. This is how a restoration mason would repair it: Buy an acrylic concrete patching material. Buy powdered masonry dye (brick red). Mix up small amounts with different ratios of dye as samples and let dry. Once you have a matching color go ahead and install according to manufacturers specifications. Sometimes you can add black or buff dyes to the red in case you have darker reds or orangish red.
    Good luck
