Can any concrete floor be polished?

Almost all concrete substrates can be polished. Floors which are saturated with oil, or are in environments where they will constantly be exposed to acids, are probably not good candidates for a polished concrete floor system. Also, some light weight concretes consist of very porous aggregate which are very difficult to polish.

It is very important to note when considering polished concrete that each concrete slab is unique and the outcome to the polishing process will vary, depending on many factors.  Although your concrete may be a candidate for polishing, it’s always a good idea to confirm your expectations to make sure you will like the results.  Our professional estimators will review these expectations with you.

Can you polish floors with radiant heat?

Radiant heat is usually 4″ below the surface of the concrete, therefore, should be fine for a polished concrete installation as long as quality control is done to ensure the depth.

What’s the difference between polished and sealed concrete?

Just like polishing a stone, the surface of the concrete floor is ground using progressively finer grits to smooth and refine the surface. Once refined, you’re left with a smooth surface that refracts light and is extremely durable. The concrete itself is the final wear surface.

With a topical sealer, a material (sealer or wax) is applied to the surface of the concrete to make it shiny or reflective. The applied material then become the wear surface.  As the sealer wears off and dulls, it must be re-applied or stripped off.

How soon can I use the floor after the polishing?

A polished concrete floor can be walked on during the grind and polish process. There is no ‘cure’ time since it is a mechanical process. The floor is immediately available for full operations once the process is completed.

How much does polished concrete cost?

The cost for polishing depends on a handful of variables such as; the condition of the existing concrete, the degree of aggregate exposure, the level of polish, the amount of edging (open space or multiple interior walls), and the overall size of the project.  In almost all cases, polishing is going to be the most economical solution long term.

Is a polished concrete floor stain proof?

No, the floor is not stain proof. It is more stain resistant than a regular concrete floor because the pores in the floor are closed up so tight that it keeps liquids on the surface longer looking for a way to penetrate, allowing for a longer time to respond in getting spills cleaned up. However if a liquid is left long enough on the surface stains may result.

Can polished concrete be stain & chemical resistant?

A stain blocker or sealer can be added to the surface of polished concrete to aide in helping with stains and chemicals. Depending on which product is used will depend on how much the floor will be stain and chemical resistant.
