How long does it take to dry and cure?

All curing and drying times are based on good site conditions i.e. an air temperature of 20o C and good ventilation. Allow between 20-30 minutes for the 1st coat and approximately 30-60 minutes for the 2nd coat. Sites that are cold, humid or damp or in areas where airflow is poor, will prolong drying and curing times, so allowances should be made accordingly. Keep the subfloor completely clear of other trades and foot traffic until cured. The product should cure to provide a glossy orange coloured film. Inspect to ensure a pinhole free film has been attained.
