What Are The Steps Of Polishing A Concrete Floor?
A diamond polished concrete floor is very time consuming if done correctly. This is due to the fact that there are at least 10 to 15 steps involved. The general rule is to start the initial grinding with a coarse 16 or 30 grit diamond and finish with a 1500 or 3000 grit diamond depending on the gloss level required. These diamonds are impregnated inside a metal or resin bonded segment. Typically the diamonds grit size will double once the first grind has been carried out.
The use of 16 or 30 grit size diamonds, then use 60/80 grit diamonds followed by the 120 grit metal bond segments. We then start the polishing process with a 50 grit diamond resin pad instead of a metal segment. When using the resin pads the steps may be 100, then 200, 400, 800, 1500 and finally 3000 grit.
Throughout the process we use a densifier to harden the concrete surface which allows the concrete to be polished. A number of densifiers can be used, these consist of a lithium, potassium sodium silicates. A grouting chemical is also used throughout the process to fill in any holes, cracks or imperfections that were exposed from the initial coarse grinding step.
The concrete is then sealed with a natural look impregnating sealer. This sealer penetrates 2-5mm inside the pores of the concrete preventing any deep staining from oils and spills
There are various custom options for your concrete polished floor. The main points you will need to discuss with us and decide on for your project are: the level of polish sheen you want (matte gloss to high gloss); whether you want a natural concrete polished floor or a decorative Color Stain; whether you want aggregate exposed for added effect or not.
