If larger quantities are being mixed the temperature of Sikadur-Combiflex CF Adhesive Normal will increase due to the chemical reaction, resulting in a reduced pot life.
Waiting Time / Overcoating

Sikadur-Combiflex CF Adhesive Normal may be overcoated with an epoxy coating. If this is required, do not smooth the adhesive with detergent. If waiting time between application of adhesive and overcoating is to be longer than 2 days, the adhesive must be blinded to excess with quartz sand immediately after application.
