Dryvit PMR finishes can be applied over properly prepared substrates such as Dryvit EIFS, exterior masonry, stucco, precast, cast-in-place concrete and other approved substrates. The finishes are also suitable for interior applications. All finishes can be trowel applied or spray applied with a hopper gun or pole gun-type sprayer.
• Surface must be smooth and free of imperfections to ensure satisfactory appearance.
• Interior and exterior surfaces must be above 40 °F (4 °C) when applying finishes and must be clean, dry, structurally sound and free of efflorescence, grease, oil, form release agents and curing compounds. Dryvit Reinforced Base Coat: The base coat must dry and have cured for a minimum of 24 hours before application of any finish.
Concrete: Shall be dry and have cured a minimum of 28 days prior to application of the finishes. If efflorescence, form release agents or curing compounds are present on the concrete surface, the surface shall be thoroughly cleaned with an appropriate commercial cleaner or method to remove any residue that will affect surface adhesion. Refer to ASTM D 4261, D 4260, D 4259, and D 4258 for various options. All projections shall be removed and small voids filled with Dryvit Primus, Primus DM, Genesis or Genesis DM mixture. Dryvit Color Prime shall be applied to the prepared concrete surface using a roller or brush (see product data sheet for mixing and application) prior to application of the finish.
Masonry: The masonry surface, with joints struck flush, shall be “skim coated” with Dryvit Primus, Primus DM, Genesis or Genesis DM mixture (see product data sheet for mixing and application) to produce a smooth, level surface.
Stucco: Dryvit Color Prime, Color Prime W or Primer with Sand shall be applied over the cured brown coat surface using a roller or brush (see product data sheet for mixing and application) prior to applying the finish. If additives are present in the stucco, a test patch shall be made and bond strength checked prior to application.
