Caulk Shiplap Siding

It is specifically designed for exterior siding and is manufactured using recycled materials that are extremely dimensionally stable and resistant to rot and decay.

Caulk shiplap siding.

Some of the most commonly caulked areas of siding include both corners and crevices as well as some butt joints and window and door trim boards. Bottom of siding boards should not be caulked. Step 6 seal with caulk. Insert the new piece of shiplap siding into the cut out area and nail with concrete covered siding nails.

Make the seams as smooth as possible. Run a bead of caulk along the edge of the newly installed shiplap siding. The siding expands and contracts with temperature and humidity. While paint does tend to somewhat glue these pieces together caulking them is never advised and can cause permanent damage.

Unpainted caulk is impossible to clean and attracts dust. Be sure to paint the caulk even if it s the same color as your shiplap. Caulk makes the entire project come together and look seamless. Press any excess caulk on your finger into each gap created by the lap siding and then smooth.

Cut a tiny opening with a utility knife not the cutter on the caulk gun. Water is meant to exit through the bottom of each board. In my opinion caulking between the seams in any lapped siding either horizontal or vertical is not good practice but not just because of any potential vapor barrier effect. The process of filling them all is tedious and slow but in my opinion very necessary.

Smooth out the caulk with your finger or putty knife. Step 7 sand the edges. Also avoid caulking tongue and groove siding boards together. Don t apply too much caulk.

When to use caulk on exterior siding siding caulk can be used on several different areas of your exterior siding to help prevent water damage and moisture buildup. After the caulk is dry use the sandpaper to sand away the rough edges and built up caulk. For best results use paintable caulk.
