We have a 13 year old polished concrete floor. In our high traffic areas, mainly the kitchen, the floor has lost its beauty & is looking dull. Is it possible to re polish a concrete floor?

The approach on rejuvenating your floor initally depends if the original floor was machine polished or if it was a grind and seal job.

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.

Can we put lights in our concrete?

Do I need to advise the concreter and or supplier that the concrete will be polished?

Yes, this will avoid the concrete supplier from sending truck deliveries from different depots and using different batches of concrete. The concreter can then also take special care to avoid screed marks and aggregate inconsistency.

We have a garage with a maroon type colour concrete floor. It has a few paint stains etc on it. I was thinking of giving it a good sanding, with some type of machine no doubt & then painting some kind of clear sealer on it. Can any concrete floor be sande

Yes, any concrete floor can be ground and sealed or mechanically polished.

What is the difference between a sealed floor and a polished floor?

A sealed floor (also known as a Grind and Seal) is machine grinding to the desired exposure followed by a Surface or Topical Sealer just like a timber floor.

What other factors/variables to do with the cement layer and concreter are important for ensuring the polished concrete job is finished perfectly?

New home builders should consult with their concrete polisher to ensure that their slab is poured with concrete polishing in mind.

When is it the best time to speak to my polisher?
