Repairing Cracks & Holes in Stucco

Stucco is one of the most durable wall surfaces available, but because of its rigid nature, stucco can develop cracks and holes over time due to settling and impact damage. Once a crack or hole develops it is important to seal it from water to prevent further deterioration.

Step 1: Widen the crack to a minimum of 1/4 inch using a chisel and hammer (the edges of the crack should be vertical or beveled in an inverted “V”).

Step 2: Break away any deteriorating concrete and remove loose material with a brush. QUIKRETE Stucco Repair (use for cracks less than ½ inch wide).

Step 3: Cut the nozzle tip of the QUIKRETE Stucco Repair on an angle with a utility knife to match the width of the crack and load into a standard caulk gun.

Step 4: Slowly draw the gun down the crack forcing a bead of stucco repair caulk deep into the crack. QUIKRETE Pre-Mixed Stucco Patch (use for small, non-structural aesthetic repairs).

Step 3: Stir the pre-mixed stucco using a margin trowel or putty knife.

Step 4: Spread and texture the concrete patch to match the surrounding stucco - wet the trowel to achieve a smooth finish. NOTE: for patches or cracks over 1/4 inch thick pre-mixed stucco patch should be applied in multiple layers, allowing each layer to dry before applying the next.
