Polyaspartic coatings can be applied on Epoxy coatings. Since polyaspartic exhibits higher interlayer adhesion to epoxy coatings. For old epoxy floor coatings that still adhere well to the surface, installers can apply a new polyaspartic coating to the area. The process to do so involves first mechanically shaping the existing epoxy floor by sanding it. The excess dust is then vacuumed clean and the area wiped with an appropriate solvent or adhesion catalyst to clean the surface.
