Expert Verdict — Reviewed by the SuperArbor Pro Desk
G300LS is a detailing staple for EPDM roof work: run a continuous bead on every exposed membrane cut edge and along uncured flashing edges per the system details. Choose white where appearance matters and black where matching standard black EPDM. Keep a caulk gun on the roof cart so lap sealant goes on before the splice is closed.
Use in well-ventilated conditions and follow the membrane manufacturer's installation details and jobsite safety requirements when applying sealants on commercial roofs.
Order Versico G300LS lap sealant to keep your EPDM membrane edges and splices sealed.
