Tape the area around any cracks in the laminations. Place the masking tape alongside the cracks but do not cover the cracks. If all of the separate laminations have come loose, tape along the sides of the legs or rails to prevent glue from dripping down the finished sides of the chair.
Mix the glue with water according to the manufacturer's directions. Force glue into all of the cracks and separated laminations with the putty knife. Do both sides of the crack if the cracks and separations go all the way through.
Clamp along the length of all cracks and laminations. Apply pressure to the clamps until glue oozes out of all the cracks. Wait 24 hours for the glue to dry.
Remove all the clamps and tape. Sand off all excess glue with the sandpaper. Apply stain where you sanded through to bare wood.
Spray the stained areas with spray lacquer.
