Coloured cements are made by grinding 5 to 10 percent of suitable pigments with white or ordinary gray portland cement. Air-entraining cements are made by the addition on grinding of a small amount, about 0.05 percent, of an organic agent that causes the entrainment of very fine air bubbles in a concrete. This increases the resistance of the ...

Smoothing the Surface with a Grinder. 1. Test the concrete with MOHS hardness picks before renting a grinder. Choose a representative area of the concrete, hold the #9 pick like a pencil, and apply the same pressure you would to draw a roughly 2 in (5.1 cm) pencil line on the concrete. Look and feel for a scratch.
Check the level of the grinder discs The goal is to have surface contact. Hold the machine in place for several seconds, then look at the pattern it leaves. You should see a full circle ground into the surface. If you see a half-circle, follow the directions for adjusting the level of your grinder.
