Dryvit StucCoat Finishes: Acrylic Copolymer Finish
Dryvit StucCoat is a high quality, integrally colored, acrylic copolymer finish offered in four textures. All textures include DPR (dirt pickup resistant) chemistry, which will keep the wall looking cleaner longer. Questions? Contact Us.
Dryvit StucCoat is specifically designed to provide texture and color over Portland cement based plaster, cast-on-site, pre-cast concrete and concrete masonry units. It is not for use in EIFS.
Surfaces must not be below 40 °F (4 °C) or painted and must be clean, dry, structurally sound and free of efflorescence, grease, oil, form release agents and curing compounds.
• Stucco: Finishes may be applied directly to the cured brown coat. If additives are present in the
stucco, a test patch shall be made and bond strength checked prior to application. Color Prime-W may be applied to reduce wall suction.
• Concrete: Shall have cured a minimum of 28 days prior to application of the finishes. If form release agents or curing compounds are present on the concrete surface, the surface shall be thoroughly washed with muriatic acid and flushed to remove residual acid. All projections shall be removed and small voids filled with Primus, Primus DM, Genesis or Genesis DM base coat. Dryvit Color Prime-W shall be applied to the prepared concrete surface using a roller or brush.
• Masonry: The masonry surface, with joints struck flush, shall be “skim coated” with Primus, Primus DM, Genesis or Genesis DM to produce a smooth, level surface.
Using a stainless steel trowel, apply and level a coat of Standard or Fine to a uniform thickness. (Standard – no thicker than the largest aggregate; Fine – applied in a thickness of 3/64 in (1.2 mm) –approximately 1-1/2 times the largest aggregate.) The textures are achieved by uniform hand motion and/or type of tool used. Maintain wet edge for uniformity of color and texture. For Bold or Lace, roughly apply an even coat of finish to a thickness slightly thicker than the largest aggregate size. Then, pull across the rough application coat using a horizontal trowel motion and develop a uniform thickness no greater than the largest aggregate of the material. Using a stainless steel trowel, install a coat of the Lace slightly thicker than 1/16 in (1.6 mm). The texture is either pulled out of this base, or the texture may be achieved by adding more Lace finish to the base coat using the same texture motions that are used with other plaster materials, such as a skip trowel finish. The thickness of any Lace finish texture shall not exceed 1/4 in (6.4 mm).
