Primers & Cleaners

Primers are used to improve bond strength, block staining or bleed-through, and stabilize challenging surfaces. They create a consistent, reliable surface so the restoration system performs as intended over time.

No. Primer requirements depend on the substrate, existing condition, and selected system. Some surfaces may not need a primer at all, while others absolutely require one to ensure proper adhesion and long-term performance.

Skipping a required primer can lead to adhesion failure, coating defects, and shortened system life. In many cases, it can also affect warranty eligibility if the installation does not follow the published system guidelines.

Cleaners are used to remove oils, oxidation, mildew, residue, and surface contaminants prior to coating. When adhesion issues are caused by contamination rather than surface condition, cleaning—not priming—is often the solution.

Cleaners are required when surface conditions demand it. Proper cleaning is often the difference between a coating that sticks and one that fails prematurely.

Yes—when used appropriately. Certain primers are designed to bond to metal, stabilize rust, and create a sound base for coating, provided the surface is properly prepared first.
