Dryvit Primer with Sand is a pigmented water-based acrylic primer containing fine sand that can be applied over a variety of substrates. Fine sand content develops a uniform light textured surface that imparts grip and facilitates subsequent trowel application of Dryvit textured finishes. This greatly reduces the potential for balded areas that may occur when finishes are troweled over smooth, sealed surfaces. Questions? Contact Us.

Drying Time: Will vary according to temperature, humidity, and porosity of surface coated. Under average conditions [70 °F (21 °C), 55%R.H.], Primer with Sand dries to the touch in 1 hour, and is sufficiently dry for application of finish in 3-4 hours. Protect from rain for at least four hours.
Job Conditions: Air and surface temperature for application of Primer With Sand must be 40 °F (4 °C) or higher and must remain so for a minimum of 24 hours.

A roller is recommended for application of Primer with Sand. Sufficient material should be used to uniformly coat the substrate without runs or buildup of material. Maintain a wet edge and work to a logical wall break to minimize lap marks. Backroll the wet application immediately with all strokes downward. Product may also be applied over small areas using a brush. Brush application is difficult to
apply uniformly on large areas. Spray application must be done with air assisted airless or other type of spray equipment that will not be damaged by the fine sand content.
