PrimeLock Roofing Primers
PrimeLock Roofing Primers are provide a bond between the substrate and the roof coating. The type of primer needed depends on the substrate and type of roof coating being applied. A primer should never be a substitute for proper preparation.

Smooth built-up or modified bitumen membranes contain oils, called exudate, that can bleed through and discolor roof coatings.
Primers are generally required on a metal roof regardless of whether the roof is new or old. Our rust primers are designed to be applied directly over the metal substrate.
Single Ply Roofs
Priming is not needed for EPDM and TPO membranes if our Hybrid System is installed. This system uses our EnergyGuard Aromatic Polyurethane as a base coat and primer in one.
Sprayed Polyurethane Foam Roofs
Primers are used to quickly protect newly sprayed foam from UV degradation. Existing SPF roofs are usually coated with acrylic or silicone. If silicone coatings are present, special coating procedures may be required. Contact us for more information.
Roofing primers improve adhesion by providing a stable surface between the substrate and the roof coating.
