From maximum exposure to a polished lustre, there are a variety of finishes that can be achieved with Geostone decorative concrete.
Geostone’s polished concrete range is the perfect platform for your dream house or commercial premises. Just as important as the mix you choose is the level of exposure that you request from your polisher. Exposure level is the amount of aggregate that is visible post grinding of the concrete. Aggregate is the stone that is present in all concrete mixes. There are three different levels of exposure to choose from, Nil/Minimum, Minimal/Random, and Full Exposure.
This is the hardest exposure level to achieve and it is very important that you choose an installer / concreter with the right expertise and experience. Little to no stone is visible on the concrete surface. The concrete can be polished to your desired level of shine.
About 1-3mm of concrete is ground off the surface to achieve this finish, often referred to as the salt and pepper look. There is often no stone exposure in some areas, while other areas have a little or a lot depending on how the slab was poured.
This full stone exposure is a more decorative look and is often used in homes and showrooms. This is our most popular concrete finish and it shows you as much stone as possible through your floor. Provided the concrete has been poured evenly and to the right specifications, you should have as the name suggests, full stone showing through.
