Prepping a concrete floor for polishing is one of the most difficult tasks we face in this industry. We cannot be aggressive like we can when prepping for a coating system, because there will be no coating to cover up the deep scratch patterns. We must take care to remove the surface materials while causing as little damage as possible to the concrete.
Old tile or carpet is removed revealing all kinds of issues. Mastic and carpet glue needs to be removed. Floors have issues due to moisture transmission via capillary or hydro static pressure that need to be cured. Floors develop cracks or other damage. Every floor needs a solution.
We remove old ceramic or vinyl tile using specialized high production equipment. Then we grind the surface with coarse diamond blades to remove the mastic and glues on the surface. In some situations we need to grind the top surface of the concrete removing the glues that have settled into the pores of the concrete. Then we can assess the situation to determine the appropriate solution whether a polish, self leveling application , micro topping or epoxy.
We must be aggressive while being cautious.
There are so many removal and prepping scenarios a never-ending book could be written about them. For the sake of this article we will focus on the most common materials we typically need to remove, mastics (glues) and epoxy.
When it comes to prepping for polished concrete the first and most important question is: What is the desired outcome? Is it a cream polish or a heavy aggregate exposure? Is it a full mechanical polish or a chemical polish? Knowing the answer to these questions will determine how to proceed.
