Roof Sealants & Cements · 10.3 oz × 2-pack
Dicor Self-Leveling Lap Sealant
Two tubes of the industry-standard Dicor 501LSW lap sealant. If you're doing a planned maintenance pass — not just patching a single vent — buy the 2-pack and cover the entire roof in one session.
One tube per vent flange is the standard estimate. Two tubes gets you two flanges plus screw-head coverage for a mid-length RV or a small flat-roof structure with a single vent penetration.
For a full RV with 4–6 vent flanges, add a third tube or buy the Better Kit, which includes three tubes plus Eternabond tape and a gallon of Liquid Rubber.
Dicor 501LSW: the sealant that RV technicians and flat-roof contractors have used as the benchmark for decades.
