3 Common types of Exposures

NIL/Minimum

A flawless finish, this option is generally only available to those who are planning on polishing their concrete before it has been placed. This finish depends largely on the concrete placement as any imperfections on the concretes surface will dictate how the final product will present. This process generally requires 0-3 mm ground off the surface.

Random

A combination of minimum and full exposure, this type of finish is very common for renovations and old concrete. As the concrete was never intended to be polished, the aggregate location within the concrete can vary in depth from the surface. This process can require anywhere from 3mm-10mm ground off the surface.

Full Exposure

The most common finish, this look is perfect to freshen up the home. Full aggregate exposure is the most labor intensive, as it can require 3-4 passes with the diamond grinding machine. If a new slab is intended to be full aggregate exposure, the concrete placing contractor should be notified and a meeting with the polishing contractor should be arranged prior to concrete placement, as the aggregate location within the slab is crucial to insure a perfect finished product. This process can require anywhere from 3 mm-20 mm ground off the surface.

The resilience of the Mechanically Polished Concrete in most instances relates directly to the gloss level and will last a lifetime if cared for properly. Generally, the higher the gloss, the tougher your concrete floor will be.

Grind and Seal

This finish is perfect for garages, outdoor and pool areas. Less labor intensive than the MPC this process involves 3-4 passes of diamond grinding to remove scratches and achieve the desired level of stone exposure. A clear sealer is then applied to give protection and desired finish, the sealer is available in matte, satin and high gloss.

Pavilion Finish / Acid Etching

Our Pavilion finish is very similar to “exposed aggregate” or “sandblasted” concrete. Perfect for pool areas, driveways, alfresco areas and any outdoor area where slip resistance is crucial. This process involves diamond grinding the concrete to expose the aggregate, then finer grinding/polishing to a smooth surface. We then apply acid or similar products to the surface, while agitating the surface with stiff brooms. The acid reacts by dissolving the cement leaving the cement matrix lower than the surrounding aggregate.

How do I clean polished concrete?

Cleaning polished concrete is cost effective and eco-friendly. Not only does the exposed aggregate hide dust, a daily clean only requires a dry micro-fiber dust mop. For a weekly clean polished concrete can be vacuumed, followed by the use hot water combined with a specifically made cleaner or a PH-neutral cleaner. Steam cleaning is a big no as it will react with the densification of the concrete leaving the surface patchy and cloudy.

JPV Concrete Polishing recommends the use of “KOH” cleaning products.

How do I know which level of exposure to select?

While we will do our best to achieve the exposure you desire, the level of aggregate exposure can often be dependent on how the concrete was originally poured and finished. If the concrete is old or has had previous flooring options such as tiles or carpet, full stone will be your best option. For further information, it would be best to talk to one of our friendly staff members.

Is polished concrete colder than tiles?

Concrete has fantastic thermal mass properties. Thermal mass absorbs heat to keep the interior of a building cool throughout the day, generally overnight or when the ambient temperature drops, the cool air will draw the warmth out of the concrete, warming the rooms where the concrete is exposed.

What if I have cracks in my concrete?

As this is a natural wear and tear, we cannot remove them. However, if choosing our Mechanically Polished concrete step 3 of our process is what we call “power grouting”. This involves the application of a polymer, which is then ground through with the grinders. This results in the polymer mixing with the dust generated, forming a putty like substance that is rammed into all the holes and cracks on the surface. While this process ensures a smooth surface, it also helps to colour match the grout as it uses the existing concrete colour within the dust. Larger holes and cracks will be patched by using either a standard polish-able patching compound or a polish-able 2-part resin compound.

How much does Mechanically Polished Concrete cost?

We generally work off a square meter rate, however, each project and each surface finish all vary in cost. It is best to call us and arrange a quote for your specific space.

Is polished concrete slippery when wet?

Mechanical Polished Concrete is no more slippery than your standard glossy house tiles when wet. When working around a pool or outdoor area, we recommend our pavilion finish or a grind and seal with the application of a slip resistant broadcasting. A Honed finish can also be achieved to create a slip resistant surface.
