Area Preparation
Where applicable, remove old sealant or caulking. Thoroughly dry the joints or surfaces, where the TOP GUN 400 will be applied. Remove all dirt, dust, oil, mildew, loose paint or other contaminants. Bare surfaces should be primed before caulking.
Application Details
Install backer-rod uniformly into deep cracks to control sealant depth. For cracks up to 1 1/2 inch wide, set the backer-rod from 1/4 to 1/2 inch deep. Bond breaker tape may be used for joints not deep enough for backer-rod. Cut nozzle at a 45º angle. Fill joints and cracks by holding the nozzle in the opening and filling completely from the bottom up. Cured bead should be between 1/8” and 1/2”. Smooth immediately with a damp sponge or towel, or other tool as required. Remove excess material with a wet cloth. Dry excess sealant may be cut away.
Drying Time
Dry Time to Paint@ 70ºF / 50% relative humidity: Latex Paint: 4 to 6 hours Oil Base Paint: 4 to 6 hours (Expect longer dry times at lower temperatures and higher relative humidity.)
Coverage
1/8” x 1/4” bead - 60 linear feet per tube 1/4” x 1/4” bead - 30 linear feet per tube.
Cleanup
Clean spills immediately with clean water and a soft cloth. Clean tools immediately after use with clean water.
