We are adding a new taller pre-primed stock base molding from Lowe’s.  It is the same base molding that we have switched to throughout the house.  Changing to a pre-primed molding versus painting over the stained oak molding saves time and paint, plus I like the look of a higher base molding.

Supplies

• Paintable Nail Filler
• Fine Grit Sanding Sponge
• Paintable Silicone Caulk
• Caulking Gun
• Paper Towels or Rags in a Box
• Bucket of Warm Water
• Trim Paint
• Painting Supplies

Prep the Molding

Remove the old base molding.  Paint the new base molding with two coats of the trim paint out in the garage BEFORE being installed.  It is easier to paint the molding on saw horses than on the ground.

Install Base Molding and Fill Nail Holes

After the new base molding is installed, fill the nail holes using a paintable nail filler.  Once the filler is dry go back and sand smooth with a sanding sponge. Make sure when you run your fingers over the base molding it feels smooth to the touch, no bumps.

Prep Caulk Tube

Open the caulk tube by cutting the tip off the tube.  Make sure you cut it at an angle for ease in application.

PRO TIP:  Don’t cut the hole too large.  It is best to err on starting with a smaller hole; you can always make it larger.

Apply the Caulk

Squeeze the caulk into the gap.  Don’t go overboard; you can always go back and add more.

Smooth the Caulk Bead

Have a bucket of warm water and paper towels next to you.  Dip your finger into the water and run it along the caulk to smooth it and fill all gaps.  And let it dry.

Add Final Paint Coat

Time to add the last coat of paint to the trim for a smooth finish.  Do all this before the carpet is installed.  You will have cement floors for a couple of weeks during this process, depending on how long it takes you to complete.

Project Complete!
