GRINDING AND SEALING CONCRETE
Older concrete floors, patios with cracks and chips, and well weathered and worn slabs are ground down to a desired depth, exposing just the right amount of aggregate. The concrete is then polished, through the grits, to 100 grit. Two sealer coats are then applied to floor.
Pros
This process has been around for many years. Reliable and durable, it brings out the best character in most floors.
Cons
It may need re-coating 5-10 years down the track in high traffic areas.
POLISHED CONCRETE
Concrete that has been poured and placed specifically with polished concrete in mind is then ground down to the desired depth to expose the existing aggregates or is just polished on the top. At 200 grit, a densifier and hardener is applied to the concrete and it is then polished through the grits up to 1500 grit. Two coats of a stain resistant sealer are then burnished in to the concrete at 3000 grit. This concrete is then so finely polished that it will emit light and hold a natural shine for the duration of the concrete itself.
Pros
Brilliant technology offering a durable product and great value for money.
Cons
May need to be burnished in high traffic areas to improve shine as concrete is worn.
Pouring Concrete Specifically for Polished Concrete
If you are wanting to expose the aggregate, then do not over vibrate the concrete. For all else, it should be well vibrated, then highly worked up with a power float finish.
