Polyurethane Sealant

Loctite PL

Roof & Flashing Polyurethane Sealant is a premium quality, commercial-grade

sealant developed specifically for roof and flashing repairs that forms permanent water and

weatherproof seals in all exterior gaps and joints. This sealant is elastic and remains flexible

to expand and contract with construction material movement to protect and retain the original

seal. It provides properties of non-sag, permanent flexibility, and corrosion resistance. It

exhibits outstanding durability and tear resistance. It usually requires no primer and resists

deterioration from weather, stress, or movement. It is UV and ozone resistant and does not

soften in the sun.

Technical Data Sheet Revision: 08/25/2021 Supersedes: 06/22/2016 Ref. #:440388 DIRECTIONS Application: Apply sealant with steady pressure, forcing bead into the joint. Fill joints from the bottom; avoid bridging of the joint, which may form air bubbles. Do not use in joints deeper than ½” (13 mm) without the use of a backer rod. The depth of the sealant should be half the width of the joint. The maximum depth is ½” (13 mm) and the minimum is ¼” (6 mm).
