Installation Steps
1

Measure and Plan

Measure each wall section. Plan cuts to minimize waste and avoid short pieces.

2

Cut Inside Corners

For inside corners, cut one piece square to wall. Cope adjoining piece to fit profile.

3

Cut Outside Corners

Cut both pieces at 45-degree angles. Test fit before nailing.

4

Nail Baseboard

Nail baseboard to wall studs, not floor. Locate studs with finder or by tapping. Nail every 16 inches.

5

Install Shoe Molding

Add quarter-round or shoe molding to cover expansion gap. Nail to baseboard, not floor.

6

Fill Nail Holes

Fill all nail holes with wood filler. Let dry and sand smooth.

7

Caulk Gaps

Apply paintable caulk along top edge where baseboard meets wall. Smooth with finger.

8

Paint or Stain

Apply paint or stain to match décor. Two coats recommended for best coverage.
