Surface to be sealed must be clean but may be damp. Maximum recommended joint width and depth for mastic applications is 1 inch wide and 5/8 inch deep. Use backer rod in deep joint sealant applications. For cartridge application, unscrew tip, use the tip to puncture the foil seal. Reattach the tip and cut to the desired size. Spouts may be reused immediately to avoid waste of material. In roofing field applications using pails, apply with a trowel or 4 inch chip brush at a minimum of ¼ inch thick and taper the edges of the application. Lucas #8500 is immediately weather resistant.

Application below 32ºF (0º C) is possible; however, curing requires free moisture in the air and will not begin until the temperature is above freezing.

Not recommended for surfaces to be painted.
