SANDING OF OLD CONCRETE FLOORS
If you have an old concrete floor, we can diamond sand it with a floor machine in two ways; wet sanding or dry sanding. In connection with dry sanding, we use an industrial vacuum cleaner to vacuum the dust from the sanding, whereas we use a wet vacuum cleaner for the concrete sludge from wet sanding, as the concrete is sanded under water.
We can sand the floor with anything from a completely coarse grit 50, or up to a grit 5000, where the floor is sanded very finely. Regardless of the sanding method, the floor can be sanded to be matt, semi-matt or full gloss.
