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). For roof tile applications, apply
a bead of Loctite PL Roof and Flashing Polyurethane Sealant sufficient to make a bond between two tiles on the upper surface
of the down slope tile. Install the upslope tile and press into the sealant bead to ensure good contact between the sealant and
both tiles.
Dry tooling is recommended within 5 minutes of extrusion. DO NOT use soapy water when tooling as this may cause the
surface to discolor. If tooling with solvent is necessary, use clean mineral spirits. Tooling results in the correct bead shape, a
neat joint, and maximum adhesion. Sealant skins within 24 hours, is functional within 3 days and reaches full cure in about 1
week.
Clean-up:
Clean tools and any uncured sealant residue immediately with mineral spirits in a well-ventilated area to the outdoors. Cured
sealant may be carefully cut away with a sharp-edged tool. Solvents have little or no effect on cured sealant.
