Common Uses

Installed at the base of all interior walls. Nail into wall studs with 2" finish nails at 16" stud spacing. MDF is a paint-only material. It does not accept stain and must be kept dry -- do not install in bathrooms or high-humidity areas.

Pro Tips

• Cut inside corners with a cope joint rather than a mitre for a tighter, longer-lasting fit. Coped joints stay closed as wood moves seasonally -- mitred inside corners tend to open up.
• Apply two coats of quality interior latex paint in satin or semi-gloss directly over the factory primer. Seal all cut edges with primer before painting -- exposed MDF edges absorb paint unevenly.
• Use a stud finder before nailing. Set all nails below the surface, fill with paintable wood filler, and sand smooth before finishing.

Frequently Asked Questions

What height baseboard should I use?
Baseboard height should be proportional to ceiling height. 3" to 3-1/2" for 8 ft ceilings, 4" to 5" for 9 ft, and 5" or taller for 10 ft and above. Taller baseboard creates a more formal appearance.

Can I use MDF moulding in a bathroom?
No. MDF absorbs moisture and swells irreversibly. Use solid wood (hemlock or cedar) moulding in bathrooms and high-humidity areas.
