To ensure optimum performance, a minimum pass thickness of 3/4” (1.90 cm) is recommended with the maximum not to exceed 1.5” (4 cm) per pass. It is recommended that the resin side pre-heater be set 10-15°F warmer than the Isocyanate side to equalize component viscosities. Maximum spray equipment temperature setting is 130°F (54°C).

This system can be sprayed on clean dry substrates down to 45°F (7°C). GacoRoofFoam 2733 must not be applied if the temperature during application is less than 5 degrees above the dew point.
