RESISTO Lastobond Smooth Seal HT FR Self-Adhesive Waterproofing Membrane, 36 in. x 65 ft.
RESISTO Lastobond Smooth Seal HT FR is a 1.2 mm self-adhesive waterproofing membrane of elastomeric SBS bitumen with glass mat reinforcement, sized 36 in. x 65 ft per roll. The anti-slip plastic film surface and two-part silicone release liner make it a fast choice for ice and water protection, and it tolerates high temperatures and 60 days of UV exposure.
Key Features:

- Glass mat strength: Glass mat reinforcement delivers great tensile strength.
- Anti-slip surface: Anti-slip plastic film top surface improves footing during installation.
- 60-day UV exposure: UV-resistant and can be left exposed for up to 60 days.
- Temperature resistant: Excellent resistance to temperature variations for demanding installations.
- Easy release liner: Silicone under-face film detaches easily in two parts for controlled application.

Expert Verdict — Reviewed by the SuperArbor Pro Desk
Pick this HT FR grade when the finished roof will run hot, such as under metal panels, or when a fire-rated membrane is specified. Apply to a clean, dry, primed-if-required deck, peeling the split liner in sections and rolling out air pockets as you work. The 60-day exposure window gives schedule flexibility, but do not exceed it.
Use fall protection and take care peeling release liner on windy days, as the membrane can fold and stick to itself.
Order RESISTO Lastobond Smooth Seal HT FR membrane for high-temperature, fire-resistant waterproofing on your next roof.
