Application Instructions

Surface Preparation: Surface must be free from grease and other residues, dry, and structurally sound. Repair drywall surfaces to required level value using appropriate spackle or mudding compound.

After completion of the required surface preparation, it is critical to test the surface with the recommended primer to ensure compatibility. Select a small, inconspicuous area of the surface for testing and apply the primer as specified. Inspect test area after 24 hours for any defects or inconsistencies before proceeding.

Application Method: Use only when the room temperature is above 60º F. Apply at recommended spread rate using a brush, roller, or spraying system. If using a spray system, back rolling is recommended. Do not overspread.
