Polished concrete floors are fast becoming a popular flooring option in commercial and residential properties. Concrete is certainly more resilient than most other flooring materials available today. It is also low maintenance so you don’t need to worry about doing more than an occasional mopping to maintain its looks.
The polishing time depends entirely on what level of polish you want, the size of the floor, and the obstructions. Here’s a look at what’s involved in the polishing process.
The Polishing Process
There are four different levels of polish, from satin-like finish to very high-gloss. To attain different finishes, we use progressively finer grinders. Needless to say, the lower levels of polish take less time. However, the process is the same.
- Step One – We start by using coarse diamond and metallic matrix grinders. These are enough to remove any kind of blemish, stains, small pits, coatings etc. This process essentially prepares the floor for further polishing.
- Step Two – During this process, we use grinders with diamond abrasives in resin or plastic matrix. Depending on the level of polish we need, we use increasingly finer grits to achieve the task. For high gloss finish, most contractors will use 1500 or finer grit.
- Step Three – During the polishing process, we also apply internal impregnating sealer to the floor. This penetrates the concrete surface and protects it. It also densifies and hardens it, making the surface more resilient. The hardened surface doesn’t need much maintenance.
What Tools Are Used?
The polishing process is achieved through a machine with different levels of grinding grits. The process is quite akin to sanding wood; for more shine, finer sandpaper is used.
Accordingly, for the first step, about 16-20 grit is used to remove any coating, and to level the surface. Then we move from one level of grit to other. After the surface is polished with a 150-grit, a chemical hardener is added to the floor.
After that progressively finer grits are used to achieve the desired levels of gloss. Depending on the area, the level of polish, and the obstacles, the polishing can take upwards of 2 to 3 days. However, you can use the surface immediately after the polishing is done.
