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.

Where do I find hydronic heating?

Can cracks be filled?

Yes, but it is best to leave fine cracks for a couple of years as there may be a chance the cracks will close again with movement.

When do you add the colour?

Colours are added by the concrete supplier and are in the mix before the concrete sets.

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.

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.

How do I care for and maintain a polished concrete floor once I am living on it?

Your floor should be maintained on a regular basis by vacuuming and cleaning in the following manner.

Why do I need a sealer?

Concrete is porous so unless a sealer, be it acrylic, polyurethane, epoxy or GTA hardener is used then the natural porosity will be susceptible to staining and scratching.
