Concrete is typically polished to make the ceiling, countertop, floor, wall or whatever other surfaces, flossy. The contractor might be looking to make the surface dustproof and easy to maintain. In other cases, the aim is to create a resistance to abrasion and make the surface appealing.
The best part of polished concrete is the uniqueness of each surface. Most concrete contractors here in the Kansas City area will give you different shines and styles to select one that works for you. While different variables can be played to produce varying styles, all the techniques can be grouped into three major categories.
Here, you get to enjoy a blend of colors and textures. The finishes are subtle, and the textures are predominantly cement. There will be little to no grinding away for the surface. The cream finish will vary based on the concrete mix that was used. It is commonly used with domestic slabs.
The blend used has to have a specific consistency if the finish will come out as intended. The contractor will need to work the surface, exposing little of the rocks in the mix. This will mean that they cannot use a blend that is too soft if the finish is durable.
To achieve the cream style, the contractor has to refine and densify the surface using abrasives until they get the desired shine. Finally, the surface has to be sealed to be protected from wear.
Salt and pepper
If you want a speckled look with the fine sands being visible, pick this style. The contractor typically removes a millimeter of the mix from the concrete surface by grinding away the surface. The idea is to reveal the aggregates and finer sands inside.
After grinding is complete, contractors use abrasives to refine the look and get as much shine, smoothness, and clarity as necessary. The sand and paper style will demand the application of grout to occupy the aeration holes.
The contractor assesses the concrete before applying chemicals like densifiers to make the surface hard and durable. After achieving the preferred look, the surface needs sealing.
Here, the contractors shine the large stones in concrete surfaces. The finish will look stony but elegant. Professionals get this finish by grinding the concrete to show the materials at the base of the concrete. They first remove 3mm off the surface to have the larger stones exposed.
Using fine abrasives, they rub the rocks until they get smoothness and clarity they like. One will need to apply grout to occupy aeration holes before applying a densifier. As a rule, soft surfaces need more chemical densifiers.
The differences in the concrete finish styles are a function of the stone and sand ratios that remain after treatment processes. Since every mix varies, so will the final appearance, thus guarantees uniqueness. Polished concrete is durable, but it must be well maintained; otherwise, it loses its shine.
Maintenance demands will differ with the decorative features added to the surface.
