Rapidry DM 35-50 is a fast setting, polymer-modified, fiber-reinforced, cement-based, dry blend adhesive and base coat for use with Dryvit systems during colder weather.
Rapidry DM 35-50 is used to adhere expanded polystyrene insulation board to approved substrates and to embed reinforcing mesh as part of the base coat. It is specifically formulated to use when job site temperatures will be between 35°F (2°C) and 50°F (10°C). It dries faster than traditional EIFS adhesives and base coats in colder weather, while providing adequate working time. Use of Rapidry DM 35-50 is not recommended if the temperature is to exceed 50°F (10°C). The rapid cure time of Rapidry DM 35-50 permits two installation steps to be completed in colder weather during one workday, i.e., insulation board installation and rasping or base coat and finish application.
