Hi Jeff. That’s a nice size garage. Super Sealer-30 is a 30% solids, solvent-based acrylic clear coat sealer. The plasticizers in the rubber are reacting to the solvent-based sealer and bonding. This is a common issue with acrylics. Applying the sealer too thick can cause the issue as well. All acrylics need to be applied in thin coats.

If you want to apply a new coating such as HellFire, it will require that you remove all of the Super Seal-30 via grinding to expose the bare concrete. HellFire and other high-performing coatings require removal of any existing coatings or sealers before application. Once HellFire is applied, you wont’ have a problem with rubber mats, oil, or gas.

Hi John. Yes, HellFire or any other coating for the matter will work just fine with in-floor heating.

Hi Taylor. Yes, they are very similar. HellFire has a higher solids content of 72% vs 50%. This means that it will be slightly thicker after it cures for a given set coverage rate. However, overall thickness for these types of coatings doesn’t usually determine how well they perform. In addition, they don’t hide imperfections in the concrete well. TruAlloy has a higher continuous heat resistance of 400 degrees vs 350 degrees if that is important for your use.
