How to stop garage epoxy coating peeling?

[RK07]

Hi Community - I'm planning my second garage epoxy project for my new home and would love some advice. I completed my first project a couple of years ago using the following materials:

• https://www.bunnings.com.au/rust-oleum-grey-gloss-epoxyshield-2-5-car-concrete-and-garage-floor-coat...
• https://concretecoatingsealers.com.au/product/epoxy-flake-flooring-kit/

I’m happy with the results overall, but I have two key questions before starting my second project:

• Are these products commercial grade? I've noticed that professionally done epoxy floor at my friends' places seem to have a much thicker epoxy layer. Is there a difference in quality or application technique?
• Peeling Issue – I've noticed some peeling in my garage epoxy. What could have gone wrong during the application and what’s the best way to fix it now?

Would appreciate any tips or recommendations. Thanks in advance.

Hi @RK07,

I can only speak to our product, but it is for residential DIY use and wouldn't typically be considered a commercial-grade product. The Rustoleum product is designed to be applied with a roller. There are other products on the market that are designed to be poured on, which could result in thicker layers. However, they must be applied on very flat surfaces as they self-level.

Peeling generally occurs in the zones where hot tyres come to rest. These areas can be touched up with epoxy paint, and if you are going with the same colour for your second garage project, you can use that paint. These zones must be thoroughly degreased and etched before the painting process. Any contaminants in these areas can cause the paint to pull off when hot tyres are left over them.

Please let me know if you have any questions.

Thank you @MitchellMc  for your reply. Apologies, I mistakenly pasted the wrong product link instead of the top coat link that I used.

The area where peeling occurred was not sanded and cleaned properly. Otherwise, the epoxy is still in great condition and has maintained its shine even after a couple of years.
For my next project, I will make sure the surface is properly prepared. I am considering using this product—do you recommend any other alternatives?

Hello @RK07 

If you are using a certain product for example like Dy-Mark or Berger it would always be best to use the recommended primer/etcher that the paint is specifying. The Rust-Oleum Concrete And Garage Clean And Etch is a two-in-one product as it cleans and etches the concrete floor at the same time. There are other etchers such as the White Knight 1kg Ultra Pave Concrete Etcher and Berger Jet Dry 1kg Active Etch. Just keep in mind that product compatibility is very important because as these products have been tested to work with their respective paint products. 

If you need further assistance, please let us know.
