10 Steps of Concrete Polishing Process
Polished concrete floor is a lustrous, glass-suchlike finish. You can choose nearly any color, produce patterns with aphorism cuts, or bed summations or intriguing objects into the concrete previous to polishing. The reflectivity of the floorings can also be controlled by using different situations of concrete polishing. Polished concrete is popular in marketable structures because it’s easy to maintain. Polished floors require dust mopping and occasional use of a cleaning product.
Simply put, polishing concrete is analogous to grinding wood. Heavy-duty polishing machines equipped with precipitously finer grits of diamond-saturated parts or disks are used to gradually grind down shells to the asked degree of shine and smoothness.
The Right Tooling
Before beginning the concrete polishing process, Glossy Floors performs a floor hardness test to determine which diamond tools to start with. When learning how to polish concrete, this is an important step that should not be overlooked. Once we have determined the appropriate equipment, we begin the concrete polishing process by placing the appropriate diamond tools on our grinder. Metallic diamonds are available in different hardnesses. This means that if the concrete is super hard (57,000 psi), an extra soft diamond is used to start the process.
For extremely soft concrete, an extra hard metal diamond would be needed. If you were to use an extra soft diamond on extremely soft concrete, you wouldn’t get very far. The diamond would simply be too aggressive for the concrete and would wear out. If you were to use a hard diamond on extremely hard concrete, it wouldn’t be aggressive enough to remove the concrete.
The concrete polishing process begins with the use of coarse diamond segments bonded into a metal matrix. These segments are rough enough to remove small pits, blemishes, stains, or light coatings from the floor for final sanding. Depending on the condition of the concrete, this initial roughing is usually a three to four-step process. The next steps are to fine sand the surface of the concrete using diamond abrasives embedded in a plastic or resin matrix. desired sheen. For an extremely glossy finish, a final grit of 1500 or finer can be used.
Experienced polishing crews know when to move on to the next grit by observing the floor surface and the amount of material to be removed. An impregnating sealant is applied. It not only protects the concrete from the inside but also thickens and densifies it. This eliminates the need for a topical coating, which greatly reduces maintenance (compared to if you had a coating on it). Some contractors sprinkle a commercial polishing compound on the surface as the final polishing step, to give the floor a little extra shine. the compounds also help clean any residue left on the surface from the polishing process and leave a dirt-resistant finish.
Although each has its own advantages, dry polishing is the most commonly used method in the industry today because it is faster, more convenient, and environmentally friendly. Wet polishing uses water to cool diamond abrasives and remove grinding dust. Since water reduces friction and acts as a lubricant, it increases the life of polishing abrasives. The main disadvantage of this method is cleaning. Wet polishing creates a huge amount of sludge that crews need to collect and dispose of in an environmentally friendly way.
With ng dry polishing, no water is needed. Instead, the polisher is hooked up to a dust containment system that vacuums up virtually all messes. Many contractors use a combination of wet and dry polishing methods. Typically, dry buffing is used for the initial stages of sanding, when more concrete is being removed. As the face becomes smoother, and crews switch from the essence- clicked to the finer resin- clicked diamond abrasives, they generally change to wet polishing.
Step by Step
- First, remove existing coatings. For that, use diamond abrasive (16 or 20 grit) or use more specifically aggressive tools for coating removal.
- Seal the joints and cracks with semi-rigid filler or epoxy.
- Grind the concrete with 30 or 40 grit metal bonded with diamond.
- Grind with an 80 fortitude essence clicked diamond.
- Grind with a 150 fortitude essence clicked diamond (or finer, if asked).
- Then apply a chemical hardener. That will densify the concrete.
- Polish with a 100 or 200 fortitude resin-bond diamond, or a combination of the two.
- Polish with a 400 fortitude resin bond diamond.
- Polish with an 800 fortitude resin bond diamond.
- Finish with a 1500 or 3000 fortitude resin-bond diamond, depending on the asked luster position.
- Optional – Apply a stain guard to help cover the polished face and make it easier to maintain.
We stop the concrete polishing with polishing pads on a burnisher. This will supply the concrete with its remaining shine. By now you must recognize the way to polish concrete. We plan on creating a professional video withinside the destiny so that you can visualize the way to polish concrete in place of analyzing the way to polish concrete. Visuals are the best!
