Note: Before applying Series 247 over coatings with a smooth, glossy surface, thoroughly scarify the previous coating using a power sander and 100 grit sandpaper, No. 60 mesh sanding screen or a coarse stripping pad to eliminate surface tension. Failing to uniformly degloss the entire surface or thoroughly clean all surface contamination may lead to fisheyes and/or poor adhesion. Sanding or scarification is not required when topcoating textured coatings (i.e. aggregate or colored quartz broadcast to refusal) with Series 247 if the maximum recoat time of the previous coating is met. Note: When applying Series 247 over a broadcast or mortar system, an epoxy grout coat is required.
