The ICON Technologies Butyl Rubber SkyLight Sealant (White) (12062) from Nomadic Supply Company® is the manufacturer-specified sealant for installing ICON external skylight domes on RVs, fifth wheels, travel trailers, and camper vans. A self-leveling white butyl rubber caulk in a standard 10 oz. tube, it fills the gap between the skylight flange and the roof surface to prevent water infiltration. Per ICON Technologies, mechanical fastening with installation screws is also required — the sealant alone is not sufficient.
ICON Technologies Butyl Rubber SkyLight Sealant (White) (12062) Features:
- Self-Leveling Formula. Flows into gaps and seams on contact — no tooling required. Creates full, continuous contact between the skylight flange and the RV roof surface for a complete weatherproof seal.
- ICON-Specified for All External Skylight Dome Models. This is the sealant ICON Technologies specifies for their complete line of external skylight dome installations — ensuring proper weatherproofing and compatibility with all ICON skylight models.
- Standard 10 oz. Caulk Tube. Fits any standard caulk gun. One tube provides sufficient sealant for both the initial bed coat and the final perimeter bead around the flange, including coverage over each screw head.
- White Color. Matches the white flange and roofline trim of ICON skylights for a clean, finished appearance after installation.
- Designed for RV Roof Conditions. Butyl rubber withstands the UV exposure, thermal expansion cycles, and road vibration inherent to travel trailers, fifth wheels, and motorhomes — unlike silicone sealants that can pull away under repeated flexing.
ICON Technologies Butyl Rubber SkyLight Sealant (White) (12062) Installation Instructions:
Run a thick bead of sealant around the skylight opening. Place the skylight in position. Install screws through the flange into the roof — do not overtighten. Run a second bead around the edge of the flange, looping the bead up over each screw head to fully seal the fastener penetrations.
