Deciding between polished concrete and epoxy flooring can be a very difficult task for an industrial company. This owes to the facts that both are based on similar foundations of a concrete slab but have very different flooring surfaces that find use in different environments. Concrete polished floors are created by continuous grinding with specialized machines. They have even finer polishing heads across a treated concrete slab for smooth, burnished surface. But, on the other hand, epoxy flooring is made up of multiple layers of two-component coatings. A fluid is applied to a mechanically prepared concrete surface which is cured chemically to form a durable, impervious and protective coating.
Polished concrete floors:
If the floor to be polished is not subject to harsh chemicals, extreme pH substances, wetness, and toxins then polished concrete floors are good options due to their less expensive nature. However, since polish concrete floors require regular and high maintenance they might not be the ideal solution.
Polished floors have less compressive strength than unpolished concrete, having good compressive strength is a necessary feature, and therefore trowelled epoxy floors can be considered a better solution.
Though polishing is a viable solution to even out concrete surface, however, it is not at all an option for old and cracked surfaces with significant issues. Polishing is best suited for new and fresh concrete that are relatively uniform and in the best shape.
The light reflecting the ability of the polished concrete is up to 100% improving the light efficiency of existing overhead fixtures and brightening the space overall, but this depends on the procedure and use of correct materials while installation.
As discussed above polished concrete might be a suitable option for various industrial as well as domestic environments but there is quite a long list of noticeable shortcomings and thus epoxy flooring bubbles up as a better alternative. Resin-based flooring solutions such as epoxy are available in a range of job-specific design to protect the integrity of a concrete slab being exposed to a broad spectrum of environments and usage. Epoxy systems chosen correctly can provide a broad range of benefits by improving the concrete floor weight bearing capacity and impact resistance, imparting puncture and abrasion resistance, static control protection and ability to withstand most strenuous conditions.
Epoxy systems can hide imperfections in concrete and can be used to maintain slabs that might have been destroyed otherwise. The light reflective ability of epoxy resins is 300%, which reduces the need for additional lighting thus saving energy cost.
Since, while installation epoxy is in a liquid state, it covers the surfaces completely and gives a seamless and imperious look. After being cured resin based polish system are highly resistant towards solvents, acids, and alkaline. This is particularly an advantage to industries where harsh chemicals or toxins are used. Polish concrete floors are not designed to cope with such chemical exposure and thus might absorb or retain harmful chemicals and also allow pollutants to flow through the slab into the surrounding soil and environment. Resinous coating, if properly selected, erases all these kinds of risks and vulnerability by not allowing harmful chemicals to be absorbed but only adsorbed from where they can be easily disposed of. For industries, which prefer the appearance of polished concrete combined with superior strength durability, a performance epoxy coating is the best option.
