Very flat or slightly bumpy floor polishing pads polished?

Some floor grinder machines are designed to produce a very flat floor by cutting off the high spots while some others are designed to follow the contours of the floor more. If the surface is to be polished without necessarily exposing the aggregate then only the finer resin pads need to be used on a concrete grinder that allows for movement of the pads so they can follow the contours of the surface. This will result in a polished floor without showing the pattern and texture of the exposed aggregates within the concrete which is faster and less expensive. Hardening can still be an advantage to help the durability of the surface and to produce a final gloss.

Problems with diamond floor pads exposed aggregate


Sometimes the finish of exposed aggregate can be uneven if the mix of concrete was poured unevenly or finished off poorly. Boot marks or kneeling board marks can appear suddenly because they have pushed the aggregate down further which might require grinding down another two or three millimeters (quarter of an inch) which will cost more than was quoted. Grinding this far may not be what the customer wanted either so it can be a risk.
