ProFlexRV GC28928 Exterior Side Wall RV Sealant / Caulking - Crystal Clear
ProFlex® RV Flexible Sealant is a premium-quality caulking solution engineered for the recreational vehicle (RV) industry. Offering excellent adhesion to a wide range of materials such as Fiberglass, Metal, Aluminum, Glass, Coated Steel, Wood, and Vinyl, this sealant is highly versatile. It is particularly useful for sealing exterior side wall accessories, including Windows, Marker Lights, Holding Tank Doors, Baggage Doors, Trim, Wheel Wells, and Doors, to create a watertight barrier that withstands the demanding conditions of RV travel.
Durability and Versatility Combined
Its crack-resistant formulation provides exceptional flexibility, enabling it to cope with the expansion and contraction associated with fluctuating temperatures and joint movement in RVs. The sealant also offers excellent UV resistance and is resealable, allowing it to be applied over itself when necessary. Additionally, it is paintable and resists dirt pick-up, ensuring a clean and polished appearance. Its easily applied, non-stringing formulation facilitates a smooth application process, and the cured sealant is resistant to mildew, enhancing the overall cleanliness of the applied areas.
Importance of Side Wall Seal Maintenance
Proper maintenance of side wall seals is crucial for prolonging the lifespan of your RV. Over time, existing seals can crack, shrink, or peel, allowing moisture to infiltrate and potentially cause structural damage or mold growth. Regular inspections should focus on identifying any signs of wear and tear around the side wall seals.
