Concrete polishing is the process following honing. An increment process ranging from 400 to 3000 or higher grit diamond fine abrasive tool is applied to the concrete after honing. The purpose is to create smaller scratches and therefore a smoother surface so enabling light to reflect. The higher/finer the polish/grit, the greater the light and sheen.
Concrete hardening, also known as “densifying”, is obtained by a chemical reaction between a liquid concrete hardener and the concrete surface. The porosity formed by the concrete water evaporation, as well as causing holes, as explained in the “GROUTING” process, compromises the concrete uniformity and therefore causes the surface to be more susceptible to scratching and staining. The additional cementitious material formed by the reaction between the concrete hardener and the free lime in the concrete, creates a tightening to minuscule pores, giving the concrete a greater density and hardness. Once the hardener is applied, the performance from this reaction can continue to improve for up to 2 months.
The outcome of this process results in diverse benefits: it hardens the surface, it minimizes pulverization and reduces penetration. Additionally, it enables the concrete surface to be polished at higher grits.
There are many types of concrete sealers that generally fall under two categories: topical and penetrating. The type of sealer will be determined by the area in which it is being applied – outdoor verses indoor, surface preparation, floor usage and desired look. A true Mechanical Polished Concrete floor is always sealed with a penetrating sealer.
Concrete buffing is the final process. When the polished concrete floor is sealed with a penetrating sealer, the purpose of buffing is to remove any excess sealer. When sealed topically the purpose is to exfoliate and/or burnish the surface of the topcoat sealer.
We so trust Andrew and the team of Polished Concrete Specialists that we got them to do our display floor in our Perth branch
We where so impressed with the outcome we commissioned PCS to present all of our showroom floors
PCS transformed our garage into a creative masterpiece, their advice and expertise is unrivalled
It is amazing what PCS where able to do with the damaged and uneven 90 year old concrete floor in the Katanning store
