Dryvit Color prime-W: Semi-Transparent Primer

Dryvit Color Prime-W is a water-based, acrylic, semi-transparent pigmented primer specially developed for use on stucco and other cementitious substrates. Because it is semi-transparent, tinted colors are affected by the color of the substrate. Questions? Contact Us.

Dryvit Color Prime-W is an application on cured stucco provides more uniform surface conditions and color background, while still allowing enough suction for good trowel application of Dryvit textured finishes. Surface crazing, laitance and alkaline “hot spots” in new stucco are minimized. It may also be applied over Dryvit base coats, concrete, masonry, brick and other porous surfaces where a Dryvit textured finish may be directly applied. It may be used in both interior and exterior applications. Application on Dryvit base coats in cold weather can minimize the development of efflorescence.

Substrate surface temperature must be above 40 °F (4 °C) and must be clean, dry, structurally sound and free of efflorescence, grease, oil, form release agents and curing compounds. On painted surfaces, remove all blistered, peeling or loose paint to a sound substrate. Remove gloss by sanding. Concrete should be cured for 28 days.

Application with standard airless spray equipment is recommended. Roller or brush application may also be used, but may result in a more streaky, uneven dry appearance. It is recommended to be spray applied as a “fog coat” evenly over stucco that has been damp cured for 3 days. Apply to a wet thickness sufficient to uniformly coat the substrate without runs or buildup of material. Work to a wet edge to minimize lap marks. Note: Darker colors or thicker applications may result in an opaque film. Tinting: When pails are tinted with the same color tint recipe used for pails of DPR finish, the approximate color of the finish will be developed when application is over a white substrate. Color that develops on stucco or base coats will be darker, varying with the color of cement used. Only one base is available, as tinted color matches are expected to be approximate.
