Broom Finish and Cure

What happens in this clip

Once the concrete patcher has been troweled smooth and begins to dry slightly (you will no longer see a water sheen on the surface), it's time to apply a broom finish. Use a broom, or for smaller projects, a dry paintbrush, to gently brush the surface of the patch. This creates a textured finish that helps the repair blend in with the existing concrete. After achieving the desired finish, allow the patch to set and cure for at least 24 hours before subjecting it to any foot traffic or heavy use. Always have a plan for curing, which might involve covering the patch or keeping it damp, depending on environmental conditions and product specifications, to ensure maximum strength and durability.

Goal: Match concrete texture and cure the repair

About the full video

This project provides step-by-step instructions for repairing thin concrete slabs that have pop-outs (small craters) and scaling (surface flaking). It utilizes a polymer-modified concrete patcher designed for featheredge to 1/2-inch deep repairs, ensuring a strong and durable fix that can match the existing concrete texture.

Step 4 of 5: Smooth and Finish the Surface

Once the patching compound has begun to set but is still workable, use a clean trowel to smooth the surface, striking off any excess material and feathering the edges into the surrounding concrete. For texture, you can use a stiff brush, a broom, or a concrete finishing brush to mimic the existing surface texture. This may involve light stippling or sweeping motions.
