A technique for replacing and restoring missing or damaged edges and corners on furniture and cabinets.

This attractive armoire was rescued from a landmark New York City hotel that was going out of business. The piece was in great shape except for one corner that was broken off and missing.

NOTE:  The polyester resin used in this project is available from most home improvement centers, online from auto parts stores or Amazon.

clamping a scrap piece of wood beneath the repair area
Step 1

Support the Wood Filler with a Small Board during Application

Clamp a flat smooth scrap of wood beneath the repair area to support the polyester resin during application. Spray the board first with WD-40 lubricant to limit sticking and make it release easily after the resin dries.

Step 2

Mix the Catalyst and Wood Filler Resin before Repair Application

Scoop a small amount of resin wood filler onto a flat surface and mix in the supplied catalyst before applying it to the furniture repair. Per directions, more catalyst will speed up the chemical reaction that hardens the resin.

Step 3

Apply the Activated Resin Wood Filler Quickly before It Hardens

Apply the mixture to the broken furniture quickly to fill gaps and form a thick edge that can be shaped like the original later. Neatness is not too critical, but applying sufficient mixture before the resin hardens is important.

Step 4

Cut away Excess Resin Wood Filler with a Utility Knife

Let the resin wood filler set to a firm-but-pliable consistency. Remove most of the excess material from the furniture repair. Start by cutting the edges with a utility knife, leaving enough margin for finer shaping in the next steps.

Step 5

Shape the Fully-hardened Resin Wood Filler

Unclamp the wood support and begin shaping the fully-hardened resin wood filler. Use a wood rasp or stainless steel micro-blade that is designed to remain free of debris. Contour the surface to mimic the undamaged area of the furniture.

Step 6

Smooth the Resin Wood Filler Furniture Repair with Sandpaper

Wrap sandpaper around a wooden dowel to smooth small curved surfaces of the furniture repair, using the free edges to hold the make-shift tool. Match the diameter of the dowel to the size of the curved resin wood filler surface.

Step 7

Paint the Completed Resin Shape with Artist's Acrylic Colors

Paint the smoothed resin wood filler with artist's acrylic colors. The resin does not accept wood stain. Mix earth tones with red or other highlights to match the wood and apply another coat if the color is not exact.

Step 8

Mask Off the Furniture Repair and Protect the Surrounding Finish

Mask off the resin wood filler repair when the acrylic paint dries. Painters tape and newspaper work well. Add a face mask for your own protection, because you will be working with an aerosol lacquer in the final step.

Step 9

Spray the Resin Wood Filler with Lacquer for Gloss

Coat the resin wood filler repair with lacquer, holding the spray can a foot from the surface. Move back and forth in several light passes, removing your finger from the spray button at the end of each pass.
