Covering exposed masonry walls with drywall is easy. But don’t forget to waterproof the surface beforehand.

Exposed masonry walls are common in basements, but you can easily tackle any underlying moisture issues and cover them with drywall for a finished look.

Materials Needed

• Stiff brush and mild detergent (to remove efflorescence)
• Waterproofing masonry paint
• Pressure-treated 1×4 furring strips
• Foam insulation board (1/2-inch)
• Construction adhesive
• Masonry nails
• Drywall sheets
• Sanding paper
• Patching compound
• Power drill
• Screws
• Paint

1. Remove Efflorescence

Before you cover the masonry walls of a basement, it’s important to deal with the possibility of moisture that may seep through them. White efflorescence is a sign that this has happened before, so remove that chalky residue with a stiff brush and mild detergent.

2. Waterproof the Walls

Coat the wall with a waterproofing masonry paint to seal out future moisture. Let dry.
