What is the grinding process?
Grinding or honing is the process that removes the surface layer of concrete leaving the aggregate exposed to a smooth, matt, low maintenance finish.Grinding marks will often be visible resulting in the need for the use of progressively finer grinding pads. Depending on the aggregate and level of grinding the concrete, a polished finish or high lustre is able to be achieved by this process.Grinding or honing is the process that removes the surface layer of concrete leaving the aggregate exposed to a smooth, matt, low maintenance finish.

Can a concrete floor be damaged and subsequently repaired?
A concrete floor though very hard and durable is not completely invincible. A floor can be damaged, for example, should someone hit the floor with a chisel. Sometimes, particularly if a slab was poured incorrectly with too wet a mix, a piece of aggregate (small stone) may become dislodged from the finished surface after a certain amount of time.

Can grout lines be removed from concrete floors when polishing an old slab
It depends on how deep the grout lines are. We usually grind 3 – 5mm off the surface but can grind up to 10mm off so if they are deeper than that then they may still be visible in the finish.

What stage do you carry out the Polishing Procedure?
We usually would carry out a preliminary grind (Stage 1) approximately 5 – 10 days after the slab has been poured and grind to the required exposure.
