What is the final step by the plasterer when finishing a sand finish coat?

• A. Brush Water over surface with plasterer brush
• B. Steel Trowel the finish
• C. Float with a rubber faced float
• D. Sand with coarse grit paper

Answer: (C)

The key action when finishing a sand finish coat is to run a rubber-faced float over the surface. This final pass gently compresses the top layer and seats the sand particles, creating a uniform, lightly textured finish that is characteristic of a sand finish. The rubber face lets you smooth and even out the surface without pulling out or over-smoothing the sand, which keeps the desired texture intact. Using a steel trowel would over-smooth the surface and erase the sand texture. Brushing with water would just moisten the surface and not provide the final texture. Sanding with coarse grit paper would remove the texture rather than create it.
