Concrete Surface Preparation - Concrete Roughness

The blasted concrete surface is too rough to be measured by tape and quantified in microns or mils. The most effective reference tool for determining concrete surface profiles is the molded rubber comparator chips, available from the International Concrete Repair Institute. These samples replicate ten grades of surface roughness, and are ...
