How to Repair Cracks in Stucco

*See step 3A if the crack is less than ½ inch wide
*See step 3B for small, non-structural aesthetic repairs

Does your stucco have a crack that’s less than 1/2 inch wide? Then load up the caulk gun.

Step 3A

Cut the nozzle tip of the Quikrete Stucco Repair at an angle with a utility knife. The cut should match the width of the crack; then load into a standard caulk gun.

Step 4A

Slowly draw the gun down the crack, forcing a bead of stucco repair caulk deep into the crack.

Trowel on some stucco patch for small, non-structural aesthetic repairs.

Step 3B

Stir Quikrete Pre-Mixed Stucco Patch using a margin trowel or putty knife.

Step 4B

Spread and texture the concrete patch to match the surrounding stucco. Then wet the trowel to achieve a smooth finish.

For patches or cracks over 1/4 inch thick, you’ll need to apply pre-mixed stucco patch in multiple layers. Allow each layer to dry before applying the next one.

  1. We have a small crack on the outside of our home coming from a basement window into the concrete base of the home. It’s apx 1/4″ and we need to know how we can repair this ourselves?

    • Hi, Diane! We would need to know more information, please. You said the crack is coming from a basement window — are you saying the window has a gap or an unwanted opening? Or is the crack located somewhere else, and if so, what type of siding is on the home?

  2. Hello, I have a big piece right in front of my house that fell off about 2 mos after I bought it! Its right under my front window, almost like a shelf but made for that, also seems it was “fixed” before & it just didn’t last. Its made out of stucco & Styrofoam. I was told to use construction type glue & that will hold it forever. It looks terrible but I’m worried that I cant fix this myself. I was quoted many different prices & I don’t “trust” anyone.
    Any advice you can give me would be greatly appreciated!!
