How to Fix Cracks in a Wooden Table Top

Sometimes boards that make up a tabletop separate because of shrinkage. When this happens cracks develop as the boards draw apart. If the cracks are not too wide, they can be fixed rather simply. If the cracks are very wide, it will be necessary to make a spline to fill the area. Here's some instructions for repairing a simple crack in a wooden tabletop.

  1. Clean the crack thoroughly using a thin blade to remove any build up of grime or dirt that may have accumulated.
  2. Force wood glue into the crack using a syringe-type glue injector.
  3. Attach clamps perpendicular to the break on both sides of the table and tighten the clamps until the crack in the tabletop is drawn closed.
  4. Allow the glue to dry completely before removing the clamps.
  5. Remove any excess glue that may have seeped onto the tabletop through the newly closed wood seam with glue remover. Be very careful not to allow any glue remover to get into the newly repaired area of the table.

Things You Will Need

  • Cracked tabletop
  • Wood glue
  • Syringe-type glue injector
  • Thin blade
  • Wood clamps
  • Glue remover


  • If the tabletop is round or oval, you'll need to use a caul clamp to hold the sides together.
  • Polish your wooden furniture weekly to protect the wood from damage and to keep it from becoming dry.
  • Never use furniture polish that contains alcohol, silicone or ammonia. These products can damage a wooden surface.


  • Serious damage can occur to your wooden tabletop if it's exposed to direct sunlight. Make sure to position tables to avoid the hot drying rays of the sun.
