We kick off our series on why coating concrete floors will save money by digging straight to the core. There are many compelling reasons, but few compare in importance to the protection coatings provide.
Pore concrete floors!
While concrete flooring is hard and strong, it has a weakness or two needing attention. The most troublesome of these is a vulnerability to liquids stemming from its porous nature.
The main bad guy here is plain, old water. In some slabs, water and other matter like carbon dioxide may penetrate through these pores and set off a chain reaction that can lead to spalling, which is the appearance of deep cracks and rust (from the steel reinforcement within). Fully repairing badly spalled concrete flooring is tough and you’ll face an uphill battle just to keep it intact.
Aside from the possible destruction occurring within, uncovered concrete also has poor resistance to chemicals in general and can be chewed away at the surface by spills and splashes. If there’s a chance your concrete floor will handle aggressive chemicals then coating is a must!
Get in early and block it out
With those points in mind, applying an impermeable coating layer with superior chemical resistance is a great financial investment. It’ll not only stop the “nasties” from wreaking havoc, it’ll also stop contaminants such as oil and silicon (e.g. tyre spray in garages) from interfering with attempts to coat it. It’s the classic case of prevention before cure and why acting immediately is preferable to the “wait and see how it holds up” approach. A good tip is to resist using water-repelling products in this endeavour because, like oil, they limit your ability to cover the concrete floor in the future.
Help with the physical stuff
Finally, there’s also a distinct physical element to the protection a coating adds. Concrete flooring doesn’t handle abrasion or heavy impact so well either, so high traffic areas and the like will benefit from a more durable finish.
