Caulk Shiplap Siding

Insert the new piece of shiplap siding into the cut out area and nail with concrete covered siding nails.

Caulk shiplap siding. 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. Don t apply too much caulk. Also avoid caulking tongue and groove siding boards together. Bottom of siding boards should not be caulked.

While paint does tend to somewhat glue these pieces together caulking them is never advised and can cause permanent damage. Patch the holes and caulk the cracks installing the planks will leave you with a ton of nail holes plus there will be cracks in the corners along the ceiling and a variety of other places. 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. Be sure to paint the caulk even if it s the same color as your shiplap.

After the caulk is dry use the sandpaper to sand away the rough edges and built up caulk. Smooth out the caulk with your finger or putty knife. It is specifically designed for exterior siding and is manufactured using recycled materials that are extremely dimensionally stable and resistant to rot and decay. Cut a tiny opening with a utility knife not the cutter on the caulk gun.

Caulk makes the entire project come together and look seamless. 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. Press any excess caulk on your finger into each gap created by the lap siding and then smooth. The siding expands and contracts with temperature and humidity.

Make the seams as smooth as possible. The process of filling them all is tedious and slow but in my opinion very necessary. Step 7 sand the edges. Run a bead of caulk along the edge of the newly installed shiplap siding.

Unpainted caulk is impossible to clean and attracts dust. Water is meant to exit through the bottom of each board. For best results use paintable caulk.
