Use a sharp garden hoe for larger areas. Step Four Sand the wood siding with an electric sander. Step Five Use a sander to feather the edges that meet bare wood. Step Six Check for rotted wood and make repairs if necessary. Step Seven Remove old caulk with a putty knife. Step Eight Brush out the dust and apply new caulk. Step Nine Brush away the sawdust.
