        An aggregate of 14-30 mesh (0.56-1.41 mm) rubber granules
        may be broadcast into the membrane at a rate of 10 lbs/100
        sqft (0.5 kg/sqm) or to refusal. The amount of rubber used
        will vary. When coating starts to gel in approximately 20 to
        30 minutes, broadcast 14-30 mesh (0.56-1.41 mm) rubber
        granules until refusal. The quantity amount of rubber granules
        will vary (normal usage is 20 lbs/100 sqft for 1 kg/sqm). When
        the coated surface is stiff enough to support the weight of
        installer without damaging the coating or when the coating
        is dry (approximately 4-6 hours), remove all loose aggregate,
        preferably by vacuum.
        Curing
        At 75°F (24°C) and 50% relative humidity, allow each coat to
        cure for 2-4 hours before proceeding subsequent coats. Cure
        time will vary depending on temperature and humidity. If more
        than 48 hours passes between coats, re-prime the surface with
