Properly sealing your RV roof is essential to prevent leaks and extend the life of your rig. Dicor Lap Sealant is one of the most trusted products for sealing RV roofs, but understanding its cure times is key to ensuring a durable, watertight seal.
Dicor Lap Sealant Cure Time Breakdown
When applied to an RV roof, Dicor Self-Leveling Lap Sealant goes through multiple curing stages:
Skin-Forming Time: 5 minutes – The sealant begins to skin over quickly, preventing dust and debris from sticking.
Initial Setup: 4-6 hours – The sealant starts to firm up, but it’s still soft underneath.
Water-Resistant Stage: 12-24 hours – Light rain or moisture won’t affect adhesion, but full curing isn’t complete.
Full Cure: 48-72 hours – The sealant reaches its final hardness and becomes fully waterproof.
Factors Affecting Cure Time
Several conditions can impact Dicor’s curing speed:
🌡 Temperature & Humidity – Warmer temperatures (above 50°F) help speed up curing, while cooler or humid conditions may slow it down.
💨 Ventilation – Proper airflow helps the sealant dry faster.
☀️ Direct Sunlight – UV exposure can accelerate the curing process but may also cause premature surface drying.
Tips for Best Results
- Ensure the roof is clean and dry before applying.
- Allow at least 24 hours before exposing to heavy rain or washing your RV.
- Avoid disturbing the sealant during curing to ensure a smooth, long-lasting bond.
By understanding Dicor Lap Sealant’s cure times, you can ensure a leak-free, professional-quality seal on your RV roof.
