Roof Primers

Before applying coatings or sealants, the key to a leak-free and long-lasting RV roof is proper surface prep. Our premium RV roof primers are engineered to improve adhesion, extend coating lifespan, and ensure maximum protection against UV, moisture, and cracking.

At The Outdoor Warehouse, we carry professional-grade primers from Dicor, Heng’s, Alpha Systems, and ProFlex — trusted by RV manufacturers, service centers, and full-time travelers. These primers chemically bond to your EPDM, TPO, fiberglass, or aluminum roof, creating a strong, tacky base that allows sealants and coatings to perform at their peak.

Why Use an RV Roof Primer?

  • Stronger Adhesion: Boosts the bond between roof surfaces and coatings or sealants.
  • UV & Weather Protection: Minimizes cracking, chalking, and bubbling caused by sun and moisture.
  • Longer Coating Lifespan: Helps coatings cure evenly for a smoother, longer-lasting finish.
  • Better Coverage: Reduces product waste by sealing porous roof materials before application.
  • Multi-Surface Performance: Formulated for EPDM rubber, TPO, fiberglass, and aluminum roofs.

How to Apply RV Roof Primer (3-Step Prep)

  1. Clean the Roof: Use a roof cleaner to remove oxidation, dirt, and chalking.
  2. Apply Evenly: Roll or brush primer in thin, even coats — focus on seams, edges, and previously coated areas.
  3. Cure Properly: Allow full dry time before applying roof coatings or sealants.

Pro Tip

Most adhesion failures occur because the roof wasn’t cleaned or primed properly. Always use a dedicated RV primer before applying coatings or tapes — especially on TPO and EPDM roofs. For best results, use primer and coating from the same manufacturer to ensure full chemical compatibility and warranty compliance.
