Surfaces to be caulked must be dry and free of all dirt, dust, oil, mildew, loose paint, old caulk or other contaminates. Bare surfaces should be primed before caulking. Only apply when sealant, surface, and air temperature are above 40ºF and rising. Do not apply on surfaces that exceed 140ºF, or when rain is expected.
- Cut nozzle at a 45º angle. Cured bead should be between 1/8” and 2” wide. Use a foam backer rod for joints that exceed 1/2” in depth.
