Fixing DIY Epoxy Applications

GarageFloorCoating.comEpoxy Flooring, Polyaspartic Leave a Comment

Being “wet behind the ears” is an idiom that refers to someone’s inexperience or naivete. In the business of epoxy coatings, this is not a good thing. As floor coating company with over 23 years experience, has come across many well-intentioned DIYers. A lot of our business involves fixing DIY epoxy applications.

Removals and Re-Coats

In a vastly overcrowded floor coatings market, inexperienced contractors and DIYers abound. The former hypes “1-day polyurea-polyaspartic systems” and the latter uses hardware store do-it-yourself kits. Whether it’s due to lack of experience, lack of technical knowledge, or simple lack of ethics, the end result is a poorly installed floor.

And that’s then we get a call. A large number of our contracts are removals and re-coats of previously epoxy-coated concrete flooring. Fading, ambering and peeling of the epoxy shortly after installation are common complaints.

Check out this video of removing yet another DIY coating:

Why Does this Occur?

There are many reasons why removals and re-coats are common with DIY and inexperienced contractor installations. The installer may be using hardware store epoxy in lieu of commercial grade coating products. But more often, it’s simply the wrong product for the job. If a 100% solids epoxy is used as the primer coat instead of a moisture-mitigating epoxy on a high-moisture substrate, peeling will occur in short order.

In other cases, the installer has simply not mastered the techniques required to properly install a quality epoxy-polyaspartic coating. Concrete preparation, crack repair, product selection and application techniques can take years to master. Add to that, the need for commercial-grade equipment like grinders, floor machines and HEPA-filtered vacuums.

Concrete Surface Profile

But the root cause of many poor installations has to do with the concrete surface profile. For epoxy products to properly bond, the concrete surface needs to have a “profile”. In other words, it needs to be rough. Smooth concrete just doesn’t provide a receptive substrate. Commercial grinders can properly prepare concrete substrates but they can be prohibitively expensive. A good propane grinder can cost between $15,000 and $20,000 US.

Ask the Right Questions

The message here is beware. For the installation of your epoxy floor, make sure you hire a professional contractor that specializes in epoxy coatings. But how do you know if you’re hiring an experienced installer? Ask the right questions.

The Wrap

Get real professional help. Real knowledge and experience in concrete preparation, crack repair, product selection and application technique are too important to forgo. Using inexperienced “contractors” selling 1-day installation hype or DIY epoxy kits to save money are in fact costly mistakes. More often than not, the result is a poor quality floor coating. We’d like to spend less of our days fixing DIY epoxy applications.
