Introduction Priming over patches means applying a seal coat to even out repairs so they don’t show under strong raking light. It helps blend repairs with the surrounding paint and surface texture. This is especially important on walls with uneven sheen or rough patches. Start with a clean, dry surface, lightly scuff the patched area, […]

Introduction Solvent pop is when tiny craters form in a clear coat as solvents escape too fast. It happens during or after spraying when remaining solvents try to evaporate quickly and bunch up. The result is small pits that can affect clarity and gloss. To avoid solvent pop, follow the product’s directions for thinning, coat

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

Introduction A concrete sealer recoat is best done when the surface is ready to bond again, so applying too soon or too late can cause problems. If you seal too soon, the new coat may not adhere well or cure correctly. If you wait too long, contaminants or the old film can prevent proper bonding.

Introduction Bubbles in concrete sealer are air pockets that form in the film as you apply it and during curing. They usually come from trapped air, fast application, or surface moisture and dust. Always check the product label and follow surface prep steps for best results. To prevent them, apply thin, even coats and backroll

Introduction Sealer haze is a cloudy film that forms on concrete when the top layer of sealer dries before the rest of the coating sets. It happens for a few common reasons, like moisture in the slab, temperature swings, or applying too thick a coat. The fix is practical and depends on the product you

Introduction Patching clay plaster means repairing damaged plaster by blending fresh material with the surrounding texture so the patch isn’t obvious. This guide treats texture and color matching as a hands-on, jobsite task you can do with basic tools. You’ll work in small steps, testing on a scrap area first. Start by cleaning the area,

Introduction Microtopping problems are defects like bubbles, pinholes, and delamination that happen when a thin decorative concrete layer can’t bond or level properly. This article covers straightforward, hands-on steps to prevent them during mixing, prep, and application. You’ll also see how surface preparation and choosing self-leveling options can help you get a smoother, longer-lasting finish.
