2. Mixing: Stir the product thoroughly before use to ensure the even distribution of polymers and bitumen.

3. Application: Apply uniformly using a brush, roller, or mechanical airless sprayer.

4. Drying Time: Allow the primer to dry completely (typically 2 to 4 hours depending on ambient temperature) before proceeding with waterproofing.
