Ramuc Type A-2 Premium Rubber is an excellent choice to recoat previously painted chlorinated rubber and synthetic rubber painted pools, specifically in VOC restricted areas. It is VOC Compliant for all 50 states and Canada. For compatibility purposes, the existing paint on a previously painted surface should be determined before painting. If the existing surface is unknown, paint chips can be taken to any Ramuc distributor/dealer to be forwarded to the Ramuc laboratory for analysis. Aged plaster should be checked for integrity. Check for hollow or weak/crumbling plaster by using a ball-peen hammer or any other comparable method. Perform repairs to the plaster before painting. Restrictions: Do not use on bare fiberglass or spas. Use Ramuc Type EP or Hi-Build Epoxy. In non-VOC affected states, consider using Premium Ramuc Type A Chlorinated Rubber on previously painted chlorinated rubber surfaces.
