There are several different options that clients can choose from when opting to have polished concrete in their premises. See below the various polished concrete finishes and services that we offer.

Surface Polish Finish (Nil Exposure)

Surface polished slabs are concrete floors where only the finished product left behind by the concrete contractor is polished. There is no rock (aggregate) exposed during the polishing process. Surface polishing is the preferred choice of finish for clients that are after an industrial look. These are the hardest floors to polish consistently, as the floor must be screeded completely flat and burnished to a high level that leaves no blade marks, inconsistencies or imperfections in the finish.

Careful consideration must be taken when choosing the surface polish finish, as many factors can affect the outcome of the final product. These floors are entirely achievable, but all variables must be considered for consistent colour and polish on this type of floor.

We can discuss and provide the information required to help get the best result for this type of finish; including advice on ordering concrete, placement, finishing and curing methods in preparation for these types of floors. However, we still cannot guarantee the look of the finished product.

Weather conditions, traffic conditions when the concrete is in transit, and other factors all influence the finishing process. Please remember that surface polishing is hardest out of all concrete polishing finishes to obtain a uniform finish, and the outcome may differ to what your initial expectations were.

Salt & Pepper Finish

Salt and pepper finish floors are achieved by grinding 1-2mm off the top of the floor to reveal only the sands and least amount of rock (aggregate) possible.

Random Exposure Finish

The random exposure finish is achieved by grinding 2-3mm of concrete off the floor. This look is more easily achievable on pre-existing slabs that may not have been poured for polishing purposes. Slabs that are more uneven and have high and low spots will achieve a better random exposure finish; due to the floor grinder being able to grind more into the higher spots and less into the lower spots. New slabs that have been designed for polished concrete can also achieve a random exposure finish; however, there are no guarantees on how little or how much exposure is achieved on these floors.

Full Aggregate Exposure Finish

A full aggregate exposure finish is where we grind up to 5mm of concrete off the top of the floor to expose as much of the rock (aggregate) in the slab as possible. With the vast amounts of different coloured aggregates and coloured cement available on the market, your options for a tailored and unique floor are virtually limitless.

Pavilion Finish (Outdoors)

The pavilion finish is used externally around pools, in al-fresco areas, driveways and pathways. The concrete is ground to reveal the rock, and then acid washed to etch the concrete paste. The acid wash process is to provide a non-slip surface on the floor. The pavilion finish resembles the traditional exposed aggregate look; only the finish is smooth and far more pleasant underfoot.

Haynes Polished Concrete also provides services for surface preparation for various floor coatings and glue/adhesive removal on existing floors.
