How to Fix Wobbly Chairs
Repairing Wobbly Chairs
Introduction:
Most homes have at least one
wood chair that is wobbly. You may have tried every
adhesive we can think of to fix them from white
glue, yellow glue, epoxy, polyurethane and even
gorilla glue. None of the glues seem to work, but
there is another way to fix wobbly wooden chairs.
Forget about putting playing cards and matchbooks
under the legs. If you have a wooden chair that
wobbles follow these steps and fix them
permanently.
Glue alone won't work. It's
natural to think that it would do the job. Like
most homeowners, you squirted some glue into a
loose joint and hoped for the best. But
unfortunately, applying a thick glob of glue is
actually counterproductive. Wood adhesives work
best when a thin film is applied to both sides of a
joint, then use pressure to force the parts
together until they dry.
Keep in mind that chairs are
light so they can be moved around easily yet the
loads a chair must accommodate are quite severe. A
chair may weigh 25 pounds, but it has to support a
person nearly 10 times its own weight.
When a
person sits, stands, twists, or shifts while
setting on a chair its joints and parts go through
strenuous cycles that can loosen the joints.
One relatively easy solution
for chairs that have only one loose joint is to
bore a pocket hole in a discreet location, usually
the underside, and spread a thin film of good
quality wood workers wood glue on the loose parts
and then drive a pocket screw through the joint to
lock it together. In most cases this will secure
the loose joint and resolve the wobbly chair
problem.
For this technique to work,
any glue from a previous repair on the joint must
be removed. An old glue joint does not create a
desirable surface on which to spread new glue to
form a solid joint. I don't recommend using this
method on an antique chair as you could diminish
its value.
If a chair has a number of
severely loose joints, label all the parts with
masking tape and then disassemble the joints. After
you have the parts disassembled, carefully remove
all the old dried glue.
Reassemble the chair using high quality wood
glue. Use wood clamps to hold the joints together
until the glue is dry.
