Estimated Time
Rot happens, even to the best of houses. All it takes is wood, water, and warmth, and before you know it solid lumber turns to mush. Exterior trim is the most vulnerable to attack by rot fungi, and it doesn't have to be very old; the trim shown here was installed only 10 years ago.
Remove the Cap
After slicing through the old caulk around the plinth (to avoid damaging the adjacent trim), Vietri pries off the cap molding and levers the plinth free. Its water-blackened backside shows how extensively moisture penetrated this assembly.
Install Flashing
Vietri protects the framing with overlapping strips of sheet-lead flashing. (Copper or waterproofing membrane also work.) Then he protects all the exposed edges of the old trim with a coat of oil-based primer.
Apply Adhesive to Trim Edges
When the primer dries, Vietri squeezes a bead of polyurethane construction adhesive over the edges of the old wood trim. He immediately beds the new plinth's mitered side pieces into the goop, which is both strong and waterproof.
Install New Cap
A PVC-solvent-based cement bonds the mitered pieces of the new plinth to each other and makes the joints waterproof. Vietri also fastens the pieces together with stainless steel trim-head screws. Dabs of acrylic glazing putty hide the screw heads.
Prep for Paint
A light sanding with 220-grit paper readies the plinth for a coat of acrylic-based primer and two coats of acrylic paint. The paint blends the repair with the rest of the trim, but it isn't needed to protect the PVC from the sun.
Remove the Rotted Wood
Before you start, make sure the area is completely dry and then dig all the soft, loose, and rotted wood away. Coat the sound wood that remains with a liquid stabilizer, this will harden the wood and form a solid foundation for the repair putty.
Reinforce Deep Damage
If the damage is very deep, drive nails into the sound wood, every few inches or so to reinforce the patching putty. Use nails with a broad head like sinkers and drive them so the heads are a bit below the finish surface of the wood profile.
Build a Form
If the damage is very deep, build a form around the area to hold the epoxy shape until it sets. Use small pieces of thin plywood or a similar light, rigid material and tack them along the face of the wood profile on all exposed sides to form a cast.
Mix the Filler
Follow the directions on the container to mix enough epoxy to fill the damaged area. Use a small plastic tube like tupperware and a putty knife to mix the epoxy and apply it right away. If the patch is very deep it may take two or more applications to fill it out completely, let each application harden before applying the next.
Apply the Filler
Once the putty is mixed, work quickly to fill the patch before it can set, usually 5 to 10 minutes. If you have small crevices that are impossible to reach with a putty knife, squeeze the epoxy into them using a plastic bag with a small hole cut in one corner as a funnel.
Fill the Form
Fill the form to overflowing with epoxy to allow for sanding and shaping it to form the new wood surface. In order to restore the surface, the filler must protrude above the original level of the surrounding trim.
Shape the Filler
As soon as the epoxy has set you can begin honing it to the shape you need. Remove the plywood form and use a paint scraper to shave the excess down to a rough surface that's level with the surrounding wood. Work before the putty can harden completely, usually about 20 or 30 minutes.
