Floor Preparation Is Most Important
Epoxy coatings have many industrial applications, one of which is concrete repair. Eco-polymer epoxies are a popular choice for concrete repairs due to their outstanding chemical resistance and ability to adhere well to wet substrates in low-temperatures. But repairing concrete with epoxy isn’t as simple as mixing up the product and slapping on a coating. The concrete surface must first be cleaned and prepped to ensure a proper bond.
Preparing A Floor
Epoxies do a great job of bonding, but increasing the surface area by making it “rough” gives an even stronger bond. Most used slab surfaces become polished over time as traffic crosses the surface. The older the slab, the more the top layer of concrete tends to become sealed with finely ground and polished debris. Polished concrete will appear shiny. Shiny is not good. The new polymer epoxy coating is going to have specified bond characteristics, and, in theory, is designed with a stronger bond than the strength of the existing concrete. The fine print on epoxy products will always say that the existing surface has to be “properly prepared” prior to application. What that means in real life, is that if the new epoxy merely floats on the surface of the concrete and bonds with the years of polished debris, rather than penetrating the substrate itself, you concrete repair will fail! Entire sections of brand new epoxy coatings have been known to shatter with use because the surface was not prepped and the epoxy polymer did not achieve an optimal bond with the substrate.
Lets get it done right the first time, any defects in the concrete being repaired can cause the bond between the original concrete and the new epoxy coating to fail, so you will need to spend some time preparing each surface for application. It is often a good idea to remove any surface contamination by “shot blasting” the concrete.This why Corner to Corner Coating is known to prepare the area to ensure a long life.
Grinding a floor when it comes to preparing concrete for an epoxy coating. Also known as profiling, it sometimes comes to the surprise of a homeowner when he or she finds out that you just can’t paint over the concrete to get the floor they want. Typical questions asked are “Why do I need to grind my concrete?”, “Which method is better?” or “Can’t I just acid etch it?” With these questions in mind, let’s look at why concrete has to be prepared in this manner and which method may be best for you to achieve the results that you want – grinding or acid etching?
Epoxy needs to bond mechanically to concrete in order for it to adhere properly. The problem however is that concrete in a garage is always finished to provide a smooth and even surface. This process reduces the porosity, thus requiring the surface to be profiled to expose the pores so that the epoxy coating can bond to it. If not, the epoxy will fail. Typically, this profiling is done by either grinding the surface or by acid etching to expose these pores.
Hundreds to Choose from
When it comes to designs and colors there are many different to really choose from and here at Corner to Corner Coating we can create one of a kind looks that no one else has. Epoxy Coating as some such a long way and we pride ourselves on a job that is well done.
