Diamond Polished Concrete Flooring
My Floors Signature finish and Hiperfloor concrete polishing solution is the way of the future as far as commercial and residential flooring goes. In the past most polished concrete floors were based on the standard grinding and sealing process, which included grinding to the required amount of aggregate exposure and applying film coat sealers to provide an enhanced, wet look. These sacrificial coatings require a long term maintenance program which consists of stripping and re-sealing the floor on a regular basis in order to keep the polished concrete look at best. This represents expensive on-going maintenance costs.
Our own Signature Floor and Hiperfloor concrete polishing system has been completed on many projects all across Brisbane, Gold Coast, Sunshine Coast and Sydney while reflecting on minimising any long term maintenance by eliminating any stripping and re-sealing programs. This is a complete flooring system which involves grinding, treating and polishing actual concrete surface with a combination of specially designed densifiers while progressively grinding the surface with finer and finer diamonds to achieve the desired gloss level. This specially designed floor solution increases abrasion resistance and impact strength while providing an extremely hard wearing polished concrete floor that requires very low maintenance. Because there are no surface coatings, the concrete floor retains its gloss for decades; we even back it with our exclusive 10 year warranty!
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 3000 grit diamond. 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 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 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.
Densifying The Concrete
A deep penetrating hardener called a densifier is used to saturate the concrete floor during the polishing process. This increases the integrity of the concrete up to 10 times its original density - transforming porous floors into a dense surface that inhibits water, oil and other contaminants from penetrating the surface. More importantly, a densifier adds abrasion/impact resistance to a concrete floor and reduces overall maintenance.
Grind and Seal Polished Concrete Flooring
This system is the standard polished concrete system where the concrete surface is ground to the desired level using coarse 16 or 30 grit metal bonded diamonds. When the desired grind level is achieved the surface is re-ground with usually a 60 grit diamond to remove any visible scratching. Grouting and patching may be required to fill any voids, holes, cracks or imperfections. The surface is then cleaned and prepared for the application of either a gloss or matte surface coating, or an impregnating enhancing sealer.
My floor uses an extensive range of penetrating and film coat sealers that can be applied to meet any specification and design requirements. These sealers range from the traditional solvent based sealers to the advanced water based environmentally friendly sealers. Choosing the right sealer plays an important part of the polished concrete process, different sealers will alter the appearance and feel of the surface. A grind and seal polished concrete floor will require stripping and or sanding followed by re-sealing on a basis of 1-5 years depending on the volume and type of traffic, the chemicals used to maintain the floor and the ongoing wear prevention strategies.
Dyes can also be used to alter the existing interior grey or coloured concrete. However, they are not UV (ultraviolet) stable and can potentially fade when used externally. These materials are applied using a sprayer during the polishing process; in which they penetrate into the concrete surface, creating natural translucent colours. Single and multiple applications are possible. (Applying dyes more than once makes for richer vibrant colours.) My Floor has a variety of 25 different coloured dye options to choose from for your next commercial or residential polished concrete project. Decorative concrete cutting may also be introduced; adding a variety of shapes and patterns to your concrete floor.
