Applied Coatings has polished hundreds of thousands sq/ft of concrete over our history. Our factory trained craftsmen have the very best training as well the industry’s largest and most advanced polishing equipment and materials.
- 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.
- The use of 16 or 30 grit size diamonds, then use 60/80 grit diamonds followed by the 120 grit metal bond segments.
- The polishing process begins with a 50-grit diamond resin pad instead of a metal segment.
- When using the resin pads the steps may be 100 grit, then 200, 400, 800, 1500 and finally 3000 grit.
- Throughout the process a densifier is used 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 and sodium silicates.
- The concrete is then sealed with a natural-look impregnating sealer; this sealer penetrates 2–5 mm inside the pores of the concrete preventing any deep staining from oils and spills.
- A final polish with a high speed burnisher will complete the project and give the concrete a mirror like finish.
