About concrete grinding & polishing

Polished concrete is a hard-wearing, low-maintenance floor that suits London lofts, kitchen extensions, galleries, offices and retail units. We grind the slab with diamonds, densify it, and polish it to anything from a soft matt to a high gloss.

Existing slabs in older buildings can often be polished, giving a characterful industrial look with honest variation. For new pours we can advise contractors on mix and finishing to get the best result.

FAQ

Concrete grinding & polishing: questions

Can my existing concrete floor be polished?

Many existing slabs can be, giving a characterful industrial look with natural variation. We check the slab for strength, cracks, coatings and contamination before quoting. New pours can be planned for polishing from the start.

What does concrete grinding and polishing involve?

We grind the surface with metal-bond diamonds to the level of aggregate exposure you want, apply a densifier to harden it, then refine with resin diamonds to the chosen sheen. A guard sealer adds stain resistance.

How long does it take?

A residential kitchen extension usually takes two to four days; larger commercial floors take longer and can be phased. The floor can usually be walked on the same day it is finished.

Is polished concrete slippery?

A satin polished concrete floor generally has good slip resistance when dry. For wet or commercial areas we recommend finishes and treatments to suit the use.

Is concrete grinding dusty?

We use dust-extracted or wet grinding equipment, so dust is controlled. The room must be empty, and we protect walls and doors around the work area.

How is polished concrete maintained, and how is it priced?

Dust-mop regularly and wash with a pH-neutral cleaner; the guard can be refreshed when it wears. Projects under 100 m² are priced per job; projects over 100 m² are priced per m², and you get a fixed written quote after a free assessment.
