Q & A: Repair a Sand-Through
I went right through the veneer when I was sanding solid-wood
edging flush on some plywood shelves. How can I fix it?
Sanding through a veneer happens to everyone sooner
or later. Here’s an old cabinetmaker’s trick
that will salvage what looks to be a hopeless situation.
First, remove the damaged veneer using a router
and a straight cutting bit (see photo, below left). Then,
select a piece of hardwood whose color and grain
resemble those of your veneer stock and cut a strip to fit
the groove (see photo, below).
Veneer seems to be getting thinner every day. To avoid
future sand-throughs, make a squiggly line with a pencil
along the hardwood-veneer joint. It will help you keep track
of how much material you’re removing.
Cut a 1/8-in.-deep groove wide enough to remove the sandthrough
area. Use a straight edge to guide the router. Cut the
groove along the full length of the cabinet side or shelf.

Glue a strip of hardwood into the groove. The strip
should be just a hair thicker than the groove is deep, so it
can be carefully sanded down flush.
