❖ The existing membrane must have sufficient adhesion to the roof. The surfaces must be clean, dry, free of stripping agents, oil, grease, silanes, salts, silicone, siloxanes and other chemicals which could cause poor adhesion.
❖ All surfaces to be coated must be thoroughly cleaned by conventional methods. For confirmation of adequate preparation carry out a pre-trial.
❖ MYCROEPDM Primer is applied either by brush, roller, or airless spray application. This primer will require one generous coat with the goal of maximizing adhesion to the existing EPDM roof membrane. The recommended coating thickness of the EDPM Primer is between 4-5 mils DFT.
❖ Drying Time: Curing time will vary depending on temperature and relative humidity.
MYCROEPDM Primer will be dry to the touch and will be ready for coating within 1-2 hours at 25°C (50% RH).
❖ The primer will remain very sticky after it dries, apply a topcoat as soon as possible after it has dried to the touch and is uniform in colour, to prevent contamination of the primed surface.
