How to seal skylights, vents, chimneys & other roof projections

1. Apply Clear Leak Stopper as you would a latex

sealant. Do not apply if rain or temperatures colder

than 40 F are expected within 24 hours.

2. Prepare the surface by removing any dirt, leaves, dust,

grime, sap, oil, mold/mildew, or other contaminants.

3. Cut the tube at a 45 angle to create an applicator tip.

Cut tip to create a 1/8" to 3/8" bead. Remember

sealants shrink when drying due to evaporation.

4. With a caulk gun apply a continuous, even bead. Hold

the gun at a 45 angle and pull toward you, pushing

caulk into the gap.

5. Smooth or “tool” the bead to a concave shape using a

caulk finishing tool or wet fingertip. Be careful only to

shape the bead—not remove it!
