Concrete Floor Polishing Process – Carr Restoration Ltd
We’ve noticed a few potential customers confuse polished concrete floors to power floated floors, which is unfortunate as they are a completely different process. And if we dare say it, one process is boring and ugly where our polished concrete flooring is beautiful.
So what is involved in our diamond polishing process?
In the most basic terms, we use diamond abrasives to sand down a concrete floor in a similar way you could sand a timber floor. Obviously diamond abrasives are far more advanced and expensive than sandpaper and concrete is great deal more durable than timber.
So here’s the basic process, its quite long as we don’t cut corners.
- First very coarse cut with metal bonded diamonds
- Second coarse cut with metal bonded diamonds
- Third cut with metal bonded diamonds or hybrid metal/resin pads
These three stages if required are used to remove the soft sandy concrete cream that forms above the aggregate when placing the concrete. Once complete you should see a nice showering of stones.
- First resin bonded diamonds
- Second resin bonded diamonds
- Third resin bonded diamonds
- Fourth resin bonded diamonds (matt level)
- Fifth resin bonded diamonds (satin level)
- Sixth resin bonded diamonds (low gloss level)
- Seventh resin bonded diamonds (high gloss level)
These last seven stages are all about smoothing away scratches in the surface of the floor and closing up pores in the stones to create a level of shine or gloss that the customer wants. The more the floor is polished with these finer grades, the more reflective the finish.
It is important to note that between each stage the floor is cleaned thoroughly and once fully polished a premium sealer is applied to help prevent staining and increase slip resistance.
The following series of photos show how the concrete changes as each set of tools smooth out the surface. No sealers or additives have been added to this concrete.
