Re-gluing a loose and wobbly chair can be done two ways. The chair can either be disassembled, or glue can be worked into the joints (without taking the chair apart).
Which method to use is determined during inspection. However a key step to both is using clamps to pull everything tight until the glue is dry. Here’s a closer look at two ways to glue loose chairs.
1st Method – Disassemble The Chair
With the use of a rubber mallet, some chairs can be taken apart. This is the preferred method, so the old glue can be scraped off the mortise and tenons (or dowels).
When disassembling a chair, it is important to lay out each part in such a way that the chair will be put back together as was. Mixing up stretchers or turning parts the wrong way will cause problems when putting the chair back together.
New glue is then applied to the connecting joinery and the chair is re-assembled and clamped tight.
2nd Method – Inject Glue Into The Joints
In many cases a chair can not be disassembled without creating damage. Or perhaps the joints are pegged, or the chair is upholstered.
In these cases it is best to use a glue injector to get glue into the loose joints.
To do this, an 1/8” hole is drilled into the cavity of the loose joint and glue is injected into the hole until it comes out the seam of the joint.
Placement of the hole is usually from underneath the chair so it won’t be seen afterwards.
The hole is then plugged, and the chair is clamped tight.
