The demand for polished concrete is growing exponentially because of its life longevity and low maintenance. In comparison to other types of flooring, concrete that has been densified, sealed, and polished will have a long life expectancy of 100+ years of service. The key to keeping the durability of polished concrete is to properly maintain it. Preserving polished floors will require dust mopping, occasional use of a cleaning product, and frequent wet mopping. Commercial buildings in Roseville tend to use polished concrete for these reasons and for its cost effectiveness.
Roseville Concrete Floor Polishing
The Roseville concrete floor polishing process with concrete grinders is similar to refinishing a wood floor with a floor sander. In that, like sandpaper that has different levels of abrasiveness, concrete grinders also have different size diamond abrasives. During the process of concrete grinding, a combination of metal bond diamond abrasives followed by resin bond diamonds is used in order to achieve the desired smoothness and shine. The lower the grit of the concrete diamond abrasive, the coarser and more aggressive the tool will be. These grits are coarse enough to remove minor pits, stains, blemishes, or light coatings of floor finishes, which can be a three-to four-step process. Joint fill should be added to the control joints to prevent grease, dirt, and food particles from getting in there. Especially if it’s a heavy traffic area because the displacement of the concrete slabs from heavy machinery running over it can be very costly. Also filling any cracks is necessary after the existing top coatings are removed. For polished concrete that has a high shine or high-gloss look, finishing with a 3000 grit will usually get that result. A concrete stain can be applied to the polished concrete if the customer desires a color for their finished polished floor. Also, a concrete sealer should be added after getting the desired sheen from concrete polishing and concrete grinding.
During the concrete polishing process, a densifier is applied to the concrete to protect and harden the concrete. This will also eliminate the need for a topical coating and reduces the maintenance on it. Some contractors will add a polishing compound onto the surface during the final polishing step, to increase the sheen look of the floor. This addition will help get off any residue remaining from the polishing process and leave a dirt-resistant finish. Applying an appropriate sealer will help protect the bare concrete.
There are two methods of concrete polishing, dry and wet. Dry polishing is the most commonly used method because it’s faster, environmentally friendly, and more convenient. Wet polishing consists of adding water to cool down the diamond abrasives, which will eliminate the dust from grinding. Using wet polishing will increase the life of the polishing abrasives because the water reduces the friction and lubricates them. The biggest disadvantage of using the wet polishing method is the clean up because it creates an abundance of slurry that must be disposed of. While using the dry method, the work of disposing of the remnants is eliminated by using a dust-containment system that vacuums up the mess. Sometimes a combination of dry and wet polishing will be used on a project. At first the dry method will be used for the initial grinding steps, and when the surface is smoother the crew will switch to wet polishing using the finer resin-bonded diamond abrasives.
Roseville concrete floor polishing is becoming increasingly popular in commercial buildings because of its cost effectiveness, low maintenance, life longevity, and clean appearance. You can achieve desired smoothness and shine during the process of dry or wet concrete polishing. Some people want it to look more coarse and others want it to look as smooth and shiny as possible. Adding a densifier and keeping up on maintenance will always increase the life expectancy of your polished concrete floor. Polished concrete can last you 100+ years, but if you went with something like tile it could only last 10 to 20 years. Another benefit to using polished concrete floor is that you are using your substrate and don’t have to add flooring to the top of it. Most flooring that you attach to the top of the substrate will have to be fixed down the road.
