Before use allow the bottle to stand at room temperature for 30 minutes prior to treatment and shake the bottle for approximately 20 seconds before dispensing. Never take the whole top off the bottle as air and moisture will enter causing the glue to deteriorate. The nozzle should be cleaned after every use using lint free wipes. Do not use cotton wool or baby wipes as the fibers can react with the adhesive and could cause an exothermic reaction.
