All masonry surfaces should be primed with Armawall Primer (thinned 50-100% with water) prior to the application of Armawall Armashield. Seal tilt slab concrete with Armawall Sealer/Bonder to ensure adhesion of topcoats.

Previously painted surfaces – in sound condition
Previously painted surfaces in sound condition should be scrubbed down with detergent and fresh water; fresh water washed and allowed to dry.

Special substrate preparation and application
Surface irregularities such as blow holes and profile defects may require patching with Armawall Filler or Patch prior to system application.
