Dicor 551LST RV Exterior Side Wall Sealant / Caulking - Tan

Dicor 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 EPDM, TPO and PVC membranes, it adheres firmly to aluminum, mortar, wood, vinyl, galvanized metal, fiberglass and concrete. It creates a secure, secondary seal along the roof’s edges and along termination rails, to create a watertight barrier that withstands the demanding conditions of RV travel.

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.

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.
