The Certi-Vex® Coating Repair 1 Gallon is a professional-grade solution to correct imperfections in previously applied concrete coatings, such as air bubbles, cobwebbing, and uneven film buildup. This specialized repair compound works with solvent or water-based systems, helping re-dissolve the coating surface for a smoother, more uniform finish without the need for full removal. Its carefully balanced evaporation rate allows coatings to dry evenly and consistently, reducing surface flaws caused by rapid solvent flash-off.
