Here's how to get professional results when you're using a caulking gun. Caulking guns aren't expensive, so don't skimp here. Once you've loaded there are several ways to open the tip, depending on what you're doing. For quick jobs like adhesive application, just cut straight across. Cut at a 45 degree angle to slow the flow down, or cut off the point to get even more control for real precision jobs.

The clapboard siding on the modern Colonial is being prepped and primed with Bob Vila Signature Collection paints. Bob is on hand as painter Jon Fish first sets, or recesses, any protruding nails securing the clapboard siding to the exterior sheathing. Next, in the corners where the clapboard siding butts up against the home's cedar shingles, the gaps are sealed with a fast-drying, paintable caulk. Caulk is also applied around window trim to prevent water infiltration. The caulk is applied with a caulking gun, and any excess material is wiped away with a damp rag. Fish then shows proper technique for painting clapboards. Beginning with the corners and side, Fish starts at the bottom of each clapboard then works across the board. Bob notes that painting with a brush allows for good coverage up and under each of the clapboards.
