All things about crafting with concrete. Concrete is a versatile material that can be used in many different ways.
Introduction Pinhole defects are tiny air-filled holes that show up in epoxy coatings on porous concrete. They happen when moisture, dust, or a lack of proper surface preparation causes the epoxy to seal in voids. Proper priming helps the surface accept the epoxy evenly and reduces pinholes as it cures. To start, clean and dry […]

Introduction Bubbles in epoxy are air pockets that form during mixing and pouring. They come from trapped air, improper mixing, or surface contamination. Taking care during prep and curing helps reduce them. Minimize bubbles by following the product’s mixing instructions and preparing the surface before pouring. Pour slowly, avoid stirring air into the resin, and

Introduction Solvent pop is tiny bubbles and craters that appear in epoxy as solvents try to escape. It happens when the coating is too thin, warm, or dries too fast, trapping solvent underneath. You can reduce it by keeping the mix and environment steady and avoiding rapid curing conditions. To avoid it, mix and apply
