• A treated 2x4 (5,1 x 10,2 cm) sill plate is required when installing your shed on concrete.
Purchase full length treated lumber, or butt shorter pieces end-to-end and seal seams with caulk.
• Use a high quality exterior grade caulk beneath all sill plates.
• Fasten 2x4 (5,1 x 10,2 cm) sill plates to slab using approved concrete anchors (fasteners not included).
• Check local code for concrete foundation requirements.
