Apply A New Broom Finish

The next step is to apply a new broom finish. This involves carefully selecting the right broom and technique for the job. Creating texture with a broom involves specific techniques to achieve the desired result. Here are some key techniques:

Direction of Strokes

Ensure consistent strokes across the concrete surface are in the desired direction. Before starting, the mason calculates the strokes’ direction based on the concrete area’s size and shape. Typically, masons pull the broom towards themselves in straight lines. They may divide the area into sections and determine the most efficient direction for the strokes to ensure even coverage.

Angle of Broom:

The mason determines the angle at which to hold the broom relative to the surface. This angle varies depending on the desired texture and the mason’s preference but is typically between 30 and 45 degrees. The mason decides where to begin applying the broom strokes. This is often at one end of the concrete surface, systematically working towards the opposite end.

Consistent Pressure:

The mason applies consistent pressure to the broom as they pull it across the surface. This helps ensure uniformity in texture and appearance. Too much pressure can result in deeper grooves, while too little pressure may not create enough texture.


To avoid gaps or inconsistencies, the mason overlaps each broom stroke slightly with the previous one. This creates a seamless texture across the entire surface.


Time the broom strokes carefully to ensure they are made while the concrete overlay is still wet and workable. Avoid waiting too long, as the concrete may start to set, making it difficult to achieve the desired texture.


Make sure the concrete surface is clean and free of debris before starting. Begin by moistening the surface slightly to help the new broom finish adhere better. Then, gently sweep it across the concrete in the desired direction using a broom with the appropriate bristle stiffness. Ensure even coverage and consistent pressure for a uniform finish. Allow the new broom finish to dry and cure properly according to manufacturer instructions for the best results.

Step 5: Allow To Cure

This is crucial for ensuring the broom finish sets correctly and achieves the desired appearance and durability. Curing times may vary depending on the type of concrete used and environmental conditions, so it is important to follow manufacturer recommendations or consult a professional for guidance.

Proper curing will help prevent issues such as cracking or flaking in the finished surface, ensuring a long-lasting and attractive result. Allow the newly applied concrete to cure for at least 24 hours before allowing foot traffic or adding additional water or coatings.
