Top 5 Effective Steps to Polish Concrete Floors for Commercial Sectors
For any industrial or commercial facilities or buildings, several steps are taken when it comes to creating the flooring. This is just to ensure that the installation process can be done in a proper way. Mostly, all industrial or commercial floors don’t need an aggregated look. But for commercial concrete polishing, the use of an aggressive 20-grit metal diamond is a necessity.
Many times, it is required to flatten a floor or remove an already existing cover. When you are planning to opt for a flatter floor, full set of the diamond grits will be required instead of a half set. The head will be kept more rigid with the full set diamond grits whereas half sets will result in a wavy floor.
- Use either 20 grit or 30 grit metal bond diamond tools for leveling out large differences on the surface or for removing older floor coatings. If there is no slippage issue or any coatings on the floor then you can start with a 50 or 60 grit metal bond diamond or some 100 to 120 grit metal bond diamond for commercial concrete polishing. The home owner’s wanted look will be obtained when the first cut is made. This first cut is also used for opening up the floor enough so that it can absorb the densifier. Without opening up properly, the floor will be less hardwearing and it will decrease the floor life. To reduce the scratch marks of 50 or 60 grit metal diamonds, use the 100 or 120 grit diamonds next.
- While grinding, it is always wise of you to use a grout in order to fill in the pin holes, hairline cracks and air pockets. Grouts can help you get a much cleaner floor with a better clarity. Groups with the acrylic base are easy to use and they are normally applied during the metal bond diamond grinding’s last stage. For commercial concrete polishing, dampen the floor with a little water spraying and then simply pour the grout on and sweep the floor with a broom to clean out the dust. Grind the surface with a grinder with the help of 100/120 metal grit diamonds when the acrylic-based grout is still wet. In the end, simply sweep the floor with the help of a foam. Avoid using a vacuum or a broom as it can remove grouts from the pores.
- After you have done your grout part, it is time you should densify the floor. The cement and the grout will be hardened after the application of densifier and so the grout won’t fall out while grinding. After the densifier dries out, any hybrid diamonds like ceramics can be used to step forward for commercial concrete polishing. These aggressive hybrid diamonds will help to remove some random scratching which is left by metal grit diamonds. These grits will then surely eliminate all the visible scratches.
- After that, polish the floor with the 400-grit resin abrasives. Depending on the gloss specifications, this would be the ending step. In case further clarity and gloss are needed on the floor, 800-grit resin pads should be used.
- The final step in the commercial concrete polishing is an application of a guard on the finished floor. For any high-traffic area, the guard must be used. But if it is not a high-traffic area, you can use a topical sealer. The concrete is penetrated by the guard, leaving a surface residue. When the concrete fully settles down, the guard is buffed off then the concrete has a glossy surface. When a topical sealer is used, then it needs to be correctly heated along with high-speed burnish to dry. Both guard and the sealer protect the floor but the sealer wears away eventually and always needs maintenance in high-traffic areas.
Every warehouse and department stores are looking for some new, greener and cost-effective ways to enhance the premise of their places. Knowing commercial concrete polishing basics can surely give all these facilities some other options for flooring with some endless possibilities.
