DIY Repair a Wooden Window Frame on a Mobile Home

Scrape all soft, moist wood out of the window frame using a chisel. Leave only hard, dry wood.

Create 1/4-inch-deep holes in the remaining dry wood using a power drill. Drill the holes at a 45-degree downward angle, leaving 1 inch between each hole.

Pour epoxy consolidant into a plastic squeeze bottle. Fill the holes in the window frame with the consolidant to strengthen the wood. Wear chemical-resistant gloves when using epoxy consolidant.

Brush the consolidant onto the wood surrounding the holes using a disposable paintbrush. Liberally apply the consolidant to fully soak the wood.

Allow the consolidant to absorb into the wood for five minutes.

Continue coating the wood with the consolidant until the wood ceases to absorb the liquid. Once the wood stops accepting the liquid, let the consolidant cure for one hour.

Scoop equivalent amounts of resin and hardener from a two-part epoxy wood filler system onto a mixing board using separate scooping utensils. Mix the resin and hardener together using a flexible putty knife. Wear chemical-resistant gloves when mixing and applying the wood filler.

Fill the voids in the wooden window frame with the epoxy wood filler using the flexible putty knife. Pack the filler into the gouges until no spaces remain. Leave a 1/4-inch-thick layer of excess filler to permit shaping and sanding. Epoxy filler typically starts curing in 30 minutes, so use your time wisely.

Allow the epoxy wood filler to harden overnight.

Shape the dried filler to match the window frame’s contours using a coarse metal rasp. File off any excess wood filler that doesn’t follow the window frame’s shape.

Sand the patched wood with 80-grit sandpaper to smooth the surface, then rub 120-grit sandpaper over the epoxy repair for fine-tuning. Wear a dust mask and safety glasses when sanding.

Wipe the wooden window frame with tack cloths. Clean all sandpaper dust off the epoxy repair.

Apply an even coat of alkyd primer to the epoxy repair using a regular paintbrush. Let the primer cure overnight.

Brush two coats of acrylic paint over the dried alkyd primer using a clean paintbrush. Let each coat cure separately for 24 hours.
