Gloss & Exposure Levels

Gloss levels

The three main choices to make when choosing your specific polished concrete floor are:

  1. Procedure: Grind and Seal or Mechanically Polished Concrete
  2. Exposure: Nil, minimum or full stone exposure
  3. Finish: The options available are basically matte, semi-gloss or high Gloss

Your personal preference is our guide to assisting you in attaining one of many looks that can be achieved with gloss levels to polished concrete floors – the matte finish is used for the more industrial/rustic look which is now being favoured by many interior designers wanting the raw material to work with furnishings and fittings in homes, shops, and other commercial spaces.

The semi-gloss is a popular choice, widely used as it doesn’t show up the dust as much as the high gloss, but still has a beautiful shine. The high gloss is for those who are looking for the wow factor and lends itself to the glamourous, high end areas. Although requiring a bit more maintenance as it can show when the floor is not spotless, this small point is outweighed by the incredible look of high gloss polished concrete finish.

Nil –Min exposure is a finish where you can see little to no stones showing through the concrete surface. This type of finish is particularly hard to achieve. It is not hard for us to achieve, but it is hard for your concreter to achieve because it requires the concrete to be poured to very stringent specifications, ensuring there are no undulations throughout the floor as this can affect the overall outcome of the finish. The slab needs to be poured perfectly flat so that we can polish it without exposing any stones.

So if you want this type of finish you need to let you concreter know before he pours the slab. If you have an existing floor that you want finished to a NIL/minimum we will do our very best, but if the slab isn’t 100% flat and there are so high and low spots it just means that you may have some small amount of aggregate showing through. This is why we call it a NIL/minimum finish instead of just NIL. The most important thing to remember is that it is up to the concreter to achieve a high standard pour in order for us to polish a high standard floor.

Minimal/Random – is a finish where you can see some areas of no stone exposure and other areas where some stones are showing through. This is most often used for budget projects as it is a more economical option and for those who really like that industrial look as well as garages, restaurants and outdoor areas. In order to achieve this look we grind the floor once which usually removes the top 1 – 3mm from the surface. This finish is referred to as the salt and pepper look, given the possible uneven exposure of stone.

Full Exposure – is probably the most popular finish and it as the names suggests shows the stones in full. It looks like the stones have been cut in half and provided the concrete has been poured evenly will usually have no areas without stone exposure. To achieve this decorative look does take time and is a more labour intensive process, and therefore is a little more expensive. Generally it requires grinding 2 – 3 times over the entire floor to achieve the desired result. Generally, we grind down 5-6 mm depending on the hardness of the slab. The full exposure finish is favored for use in homes and showrooms.

Minimal/Random EXPOSURE

This is often referred to in the industry as a salt and pepper look. It is where we grind the top 1-3mm of the surface usually going over the entire floor just once. There is often no stone exposure in some areas, and other areas have a little or a lot depending on how the slab was poured. This is often used for the industrial look, or for garages, restaurants, outdoor areas etc. and is a more cost effective option.

We got Grind & Seal to do the polished concrete in our home. They were incredibly professional and friendly to deal with during the process and the floor looks amazing – they were not the cheapest, but I think you get what you pay for – and we got top quality for a competitive price. Will definitely be recommending their services.

Craig Harris

Good service, Happy to recommend Grind & Seal. Our floors look a million bucks and came up just so well. Was a difficult job but their experience really showed and they got around all hurdles. We were so impressed. And as our cheapest quote by far we were happy that we got such a good job. Nice team and made the whole process so very easy.

Grind and Seal did a terrfific job at our property, we knew in advance of building our new home that we were going to have polished concrete downstairs, therefore we contacted Grind and Seal to speak to them about our job and they liaised with our builder/concretor to ensure that we had a concrete slab with the perfect specifications for what were after!When it came time to complete the work the guys were punctual, friendly and very professional. The place looks fantastic and they were only too happy to appease my wife's needs to inspect the job at every step ...

Karen Exner

Our idea to have a “garden party” theme for Christmas last year sounded great but our old mouldy concrete was an eyesore! Within 2 days the grind and seal team transformed our very drab rear and front yard into magnificent useable entertaining areas with minimal disruption to our lives. We have now decided on polished concrete for our extension to merge the indoor/outdoor living areas. The Grind and Seal Polished Concrete team worked hard to deliver a great result, they provided a quality product in a timely fashion, they are honest & reliable – a refreshing change in this day ...

Anyone who hasn't seen polished concrete before should definitely try it! It looks amazing and is so easy to clean - I totally love it. I got Grind And Seal to come and do my home and they were awesome - lovely guys and were really good at explaining stuff to me. Price was really reasonable and now all my friends are jealous of my floors! - Thanks Grind & Seal I will be recommending you to everyone although my floor really speaks for itself.
