Dryvit Genesis DMS: Sprayable Adhesive

Dryvit Genesis DMS: Sprayable Adhesive

Dryvit Genesis DMS is a sprayable, dry mix, polymer-modified, cementitious adhesive and base coat for use with Dryvit systems. Genesis DMS may be applied as an adhesive to either the substrate or the EPS. Questions? Contact Us.

Dryvit Genesis DMS 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. Genesis DMS is specifically formulated for spray applications. Genesis DMS may also be used for non-spray applications(e.g., notch-troweling on substrates).

Working Time: After mixing, the working time of the Genesis DMS is approximately 1-3 hours, depending on the ambient weather conditions.

Drying Time: Drying time of the Genesis DMS mixture is dependent on the air temperature and relative humidity. Under average drying conditions [70 °F (21 °C), 55% R.H.], the Genesis DMS will dry in 24 hours. Protect work from rain for at least 24 hours. Being a cementitious product, the Genesis DMS 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 DMS 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.

Application Procedure: For complete application instructions, refer to the appropriate Dryvit system application instructions.

Job Conditions:Air and surface temperatures for application of the Genesis DMS must be 40 °F (4 °C) or higher and must remain so for a minimum of 24 hours. Genesis DMS shall not be applied to the substrate when substrate and/or air temperatures are above 100 °F (38°C).

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, cement plaster, concrete or masonry
• Galvanized expanded metal lath 2.5 or 3.4 lbs/yd² (1.4 or 1.8 kg/m²) installed over a solid substrate
