Dryvit Genesis DM: Fiber Adhesive

Dryvit Genesis DM is a high-performance, fiber-reinforced, dry mix, polymer-modified, cementitious adhesive and base coat specifically formulated for use with Dryvit systems. Questions? Contact Us.

Dryvit Genesis DM is used to adhere expanded polystyrene insulation board to acceptable substrates and to embed reinforcing mesh as part of the base coat for Dryvit systems. It can also be used to level interior and exterior masonry walls.

Working Time: After mixing, the working time of the Genesis DM mixture is approximately 1 to 1 1/2 hours, depending on ambient weather conditions

Drying Time: Drying time of the Genesis DM mixture is dependent on the air temperature and relative humidity. Under average drying conditions [70 °F (21 °C), 55% R.H.], the Genesis DM mixture will dry in 24 hours. Protect work from rain for at least 24 hours. Being a cementitious product, the Genesis DM mixture develops full strength in 28 days. When used to bond expanded polystyrene insulation board to an acceptable substrate, a period of at least 24 hours must elapse prior to rasping to allow the Genesis DM mixture to form a positive bond. The installed insulation board should not be disturbed until adequate bond has developed.

Testing Information: For individual test data on this product’s properties, refer to the chart included with this document.


Job Conditions:Air and surface temperatures for application of the Genesis DM mixture must be at 40 °F (4 °C) or higher and must remain so for a minimum of 24 hours.

Temporary Protection : Shall be provided at all times until the adhesive, base coat, finish, and installation of permanent flashings, sealants, etc. are completed to protect the wall from inclement weather and other sources of damage.

Acceptable Substrates:
• Exterior grade gypsum sheathing meeting ASTM C 1396 (formerly C 79) requirements for water-resistant core or Type X core
• Exterior sheathing having a water-resistant core with fiberglass mat facers meeting ASTM C 1177
• Exterior fiber reinforced cement or calcium silicate boards
• Unglazed brick, concrete, or masonry
• New or existing cement plaster
• Galvanized expanded metal lath 2.5 or 3.4 lbs/yd2(1.4 or 1.8 kg/m²) installed over a solid substrate.
