Avoiding Pinholes & Air bubbles in Epoxy Floors
Moisture & Humidity
Every concrete floor is different from the porosity of concrete playing a major part in causing air bubbles and blisters. The concrete must be treated with an epoxy primer/sealer. If the concrete is extremely porous, then a second coat of primer/sealer should be applied.

Product Quality & Adding Solvent
You only get what you pay for. Most quality epoxies contain defoaming additives. Cheap products generally don’t – that’s why they’re cheap. Likewise, many applicators add solvent to the product. The solvent can cause pinholes as some air bubbles don’t burst when the solvent vaporises. If adding solvent don’t overdo it, only use a small volume.
