Dryvit Weatherlastic is a line of textured finishes that are 100% acrylic, utilizing DPR (Dirt Pickup Resistant) chemistry and an elastomeric binder to bridge hairline cracks. Dryvit Weatherlastic is available in four distinct textures. Weatherlastic Quarzputz, Weatherlastic Sandpebble, Weatherlastic Sandpebble Fine, Weatherlastic Adobe and achieve textures which are governed by aggregate size as well as the trowel motion in finishing the wall. Quarzputz produces an open-textured pattern in a regular or random style, Sandpebble trowels to a pebble texture, Sandpebble Fine produces a fine pebble texture; Adobe trowels to a smooth, fine sand texture.

Weatherlastic finishes are ideally suited as a protective and decorative coat over stucco, concrete, masonry, CMU and EIFS substrates.
Surfaces must not be below 40 °F (4 °C) and must be clean, dry, structurally sound and free of efflorescence, grease, oil, form release agents and curing compounds.
• Concrete: Shall have cured a minimum of 28 days prior to application of the coatings. 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 Genesis Primus, Genesis DM or Primus DM mixture. Dryvit Weatherprime 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 Genesis, Primus, Genesis DM or Primus DM mixture to produce a smooth, level surface.
• Stucco: Weatherlastic finishes shall be applied to the properly primed, cured brown coat. If additives are present in the stucco, a test patch shall be made and bond strength checked prior to application. If applied to existing stucco, one coat of Weatherprime should be applied to the brown coat before applying the Weatherlastic finish.
Thoroughly mix Weatherlastic finishes with a Goldblatt Jiffler Mixer until a uniform workable consistency is attained.
