Description
xOverview
Dicor 551LSV-1 HAPS-Free Non-Leveling Lap Sealant in ivory helps create a watertight seal along a roof edge, around air vents, vent pipes, and screw heads on RV roofs. This sealing solution is formulated for EPDM roofing yet remains compatible with a wide range of materials, offering flexible, long-lasting protection without a stiff or heavy feel.
What makes it practical
The sealant stays flexible after cure, resisting cracking as the roof expands and contracts with weather. The ivory shade helps it blend with many roof finishes, while a sun-ray stabilized composition helps prevent discoloration over time. As a HAPS-free option, it provides a user-friendly choice for ongoing maintenance without harsh fumes.
- Watertight edge sealing around roof perimeters, vents, and screw heads
- Strong adhesion to aluminum, mortar, wood, vinyl, galvanized metal, and concrete
- Non-leveling formulation that stays in place during application
Wide material compatibility
While designed for EPDM roofing, this lap sealant pairs well with most common roofing materials, including DiFlex II, Tufflex, PVC, and PriTEK TPO. It also bonds to substrates like concrete, wood, aluminum, vinyl, and more, reducing the need for multiple products on a single project.
- EPDM compatibility plus cross-material support
- Excellent adhesion to metal, masonry, wood, vinyl, and concrete
Appearance and longevity
Color matched and sun-ray stabilized to avoid fading or staining, the sealant maintains a neat look on RV roofs. It continuously seals and remains flexible, helping the roof stay easy to maintain as conditions change.
Real-world use cases
Use it along the roof edge during routine maintenance, around air vents, vent pipes, and screw heads in RVs. It can also be applied during repairs to refresh a weathered seal on varied roof assemblies, supporting a clean, professional finish.
- Vents and screw head sealing for weatherproofing
- Edge and perimeter sealing for routine roof upkeep
Tips for best results
Store in a cool place, follow cure times, and apply on clean, dry surfaces. The ivory tone remains visually unobtrusive while the sealant forms a flexible, durable seal as part of a proactive maintenance plan.
