INSTRUCTIONS FOR USE -

TOOLS: Household rags, utility knife, caulking gun, caulk, nail or awl

STEP 1: Clean the area to be caulked, removing dirt, loose paint and old caulk. Be sure the area is dry before you begin.

STEP 2: Use a utility knife to cut the tip of the spout either straight or angled. Cut off as little as possible, taking into consideration the size of the 'bead' of caulk you need. Cardboard tubes may have a second seal at the base of the spout. Insert a nail or awl through the spout to puncture the seal.

STEP 3: Load a tube of caulk into a caulking gun, making sure it's well seated at both ends.

STEP 4: Hold the gun at a slight angle. If you're filling a crack, insert the spout if you can; otherwise, run it at the surface.

STEP 5: Pull away from the bead slightly as you squeeze out the caulk, rather than push into it, which can be very messy. Use just enough caulk to do the job. (Experiment in an out-of-the-way area. You may find that you'll need less of a bead than you think.)

STEP 6: Use your finger to gently press the caulk into the corner or crack.

STEP 7: Use a damp towel or rag to clean off most of the excess caulk, then use a dry one to clean off the rest.
