Seal Trust White EPDM Lap Sealant, 10.5 oz Tubes
Seal Trust EPDM Lap Sealant is a white lap caulk for single-ply membrane applications such as EPDM or TPO, used where membrane is overlapped when applying splice or bonding adhesives. Each carton contains 10.5 oz tubes applied with a standard caulk gun. It prevents water infiltration into seams and overlaps before the adhesive cures.
Key Features:
- EPDM/TPO use: Formulated for single-ply membrane applications such as EPDM or TPO.
- Seam protection: Prevents water infiltration into seams and overlaps prior to the adhesive setting up.
- Works with adhesives: Used when applying splice and/or bonding adhesives where membrane is overlapped.
- Standard caulk gun: Applies with a standard caulk gun—no special equipment needed.
- 24-48 hour window: Bridges the 24-48 hour adhesive cure period depending on temperature and humidity.

Expert Verdict — Reviewed by the SuperArbor Pro Desk
Run lap sealant along the membrane lap edge immediately after bedding to block wind-driven rain during the adhesive cure window. Cure time stretches in cool or humid conditions, so schedule seams accordingly. Keep a tube on hand for patch work around details like pipe boots and curb flashings on EPDM roofs.
Use in ventilated areas and follow solvent/skin-contact precautions on the tube label during application.
