Concrete is a popular material used for floors and roofs, thanks to its durability, easy maintenance and attractive appearance, when polished correctly. Concrete surfaces can be polished to a finished sheen requiring no coating or waxing. However, this process requires equipment and special techniques. Learning the basic methods for polishing concrete can help homeowners tell the difference between a well-polished surface and one that was not properly polished.
The wet grinding of concrete involves using diamond abrasive grains to gradually soften the floor, deck or concrete surface. The water is used to cool the abrasion and keep dust levels low making the process safe. According to Red Concrete, wet abrasive polishing processes tend to last longer, because water acts as a lubricant. Unfortunately, the polished concrete in wet environments creates a disaster.
Dry grinding is becoming increasingly common as dust container systems improve. This technique involves grinding the floor with a polisher hooked to a vacuum system. The system contains a lot of dust so you need to improve air quality and make it cleaner. According to Red Concrete, many workers use dry polishing in the early stages and then change to a wet one.
Decks and other concrete forms with edges and corners require special techniques to soften correctly. Small, manageable polishes work best on the edge of concrete and are adjustable with flexible polishing fillings for curved areas. Workers should avoid tilting or rolling the polish, as it can cause a rippling surface. Instead, a horizontal movement with even pressure should be used to provide the best surface. Performing work on banks require greater care to polish large flat surfaces as small imperfections are more obvious.
