What polished concrete actually is

Polished concrete is not a coating. Nothing is laid on top of the slab and nothing is stuck down to it. The slab you already own is cut back with progressively finer diamond tooling until the surface you want is exposed, then chemically densified so the cement matrix hardens, then closed with a sealer chosen for the room. What you walk on is the concrete itself, which is why it does not peel, lift at the edges or wear through in the traffic lanes the way a coating does.

That is also why the outcome is decided by the slab rather than by a product brochure. Two floors poured from different mixes and taken to the same depth will not look the same. It is the reason we grind a sample on your own concrete before the main floor is committed, and the reason we post a free polished concrete sample tile to anyone still deciding.

Four decisions make the floor

Colour is set in the pour, so it is the one decision that has to be made before the concrete truck arrives. Aggregate is the stone in the mix and it determines what appears once the surface opens up. Depth of cut runs from a natural polish that keeps the cement cream through salt and pepper to full aggregate exposure. Polish level is the grit the floor is stopped at, from a 200 grit matte to a 3000 grit mirror.

Work through them in that order and there are no surprises at handover. Start with concrete colour and aggregate choices, then set the exposure on the depth of cut ladder, then pick the sheen on the polish level guide.

Why the pour matters more than the grind

A ground floor can only be as good as the concrete underneath it. Mix design, the consistency of the placement, how flat the slab was screeded and how it was cured all show up in the finished surface. A slab that was poured with polishing in mind gives a cleaner aggregate spread and an even cut across the whole floor. One that was not can still finish beautifully, but the honest answer is that it will read as a floor with character rather than a uniform one.

Timing is the other half of it. Polishing commences at a minimum concrete age of 28 days from the date of pour. Before that the concrete has not reached strength and the aggregate tears rather than cuts. If you are building, bring us in at the drawing stage rather than at practical completion. The builder and specifier guide covers slab protection, programme and the clause to put in the schedule.

What we do, and where

Four services cover almost every job. Polished concrete floors in Tauranga for interiors that have to look finished and stay easy to live with. Concrete grinding in Tauranga for levelling, glue and coating removal and preparation before another surface goes down. Concrete texturing in Tauranga where grip has to be cut into the surface rather than painted on, for steps, plazas and pool surrounds. Concrete sealing in Tauranga to protect a finished surface against stains and weather. Where a floor already exists and has simply had a hard life, concrete floor rejuvenation brings it back without a replacement slab.

We are based in Tauranga and most weeks are spent inside the Bay of Plenty, working across Mount Maunganui, Papamoa, Bethlehem, Otumoetai, Pyes Pa, Welcome Bay, Omokoroa and Te Puke, with regular travel out to Rotorua and Taupo. Larger jobs take us into the Waikato and up to Auckland. If you are unsure whether your address is in range, ring and ask rather than guessing, because the answer usually depends on the size of the floor rather than the distance.

What clients say

We went with the eco friendly ground and polished floor and we are very pleased with it. With young children in the house it takes everything they throw at it and it wipes clean in minutes.
