How to Fill Gaps in Wood Table

10 Methods on How to Fill Gaps in Wood Table:

1. Wood Glue Solution

Many gaps in wood surfaces are filled with glue alone. To fill the gap, use a disposable brush or small paintbrush to apply wood glue into the crevice and wipe away any excess with a paper towel. Finally, scrape off any excess dried glue by running your fingernail against it. Let the glue dry completely.

2. Wood Filler Paste

Wood filler paste is a mixture of wood dust and adhesive that is used to fill in tiny holes or cracks in wood surfaces. By adding the paste to these areas, it will help to even out the surface, strengthen it, and make it more durable. When using the paste, be sure not to use more than a pea-sized amount.

Next, add some very fine sawdust. This will make the filler paste less evident after it has dried. You can use a toothpick to mix the two until you have an all-white mixture that is about as stiff as peanut butter.

3. Mix Wood Glue with Sawdust

If you need to fill in more significant gaps, you must have a thicker mixture than normal wood glue. To do this, mix some sawdust with standard wood glue in a bowl or on a piece of cardboard until it has the consistency of oatmeal.

4. Spread Wood Filler Paste

If there are significant gaps between boards, use only filler paste in the gaps before sanding. Do this by wiping clean any dust off the table with a damp cloth, then squeeze some of the paste into your hand. Spread it across the gap using your fingers or a plastic utensil. You can also use an old credit card to evenly spread the filler paste over the crack. Let it dry for two hours.

5. Dap White Caulk into the Gap

Use only white caulk in significant gaps between boards. The gap must be dry and free of any dirt, dust, or oil. If an old caulk line needs to be removed, use a utility knife to score around it, then carefully pull it out with your fingers. Then wipe the gap clean with a cloth moistened with painting alcohol.

6. Cut Open a Latex Glove

Latex gloves are made of natural rubber, which is similar to latex caulk. To get the right consistency of filler paste, cut open one finger of the glove and squeeze it into your hand. Add more glue if needed until you have a mixture that is like toothpaste.

7. Squeeze White Spread Rubber Cement

In smaller gaps, rubber cement can be used. Spread some on the inside of the gap, let it dry, seal, and then sand. This glue is good because it forms a flexible bond that will not crack or split like regular white glues.

8. Prepare an Epoxy Patch

For small cracks in wood surfaces, cut open an epoxy patch and squeeze equal amounts of the resin and hardener onto a piece of cardboard. Mix it with a plastic utensil to form a beige, clay-like mixture. Spread this into the crack and let it dry for one hour. When it dries, sand it down to fill in the gaps.

9. Prepare a Putty Patch

For small holes that need to be filled in, cut open a two-part epoxy putty patch and squeeze equal amounts of the two components into a clean bowl. Mix it with your hands until it gets sticky and grainy. Apply this mixture to the hole and let it dry for one hour. When the filler is dry, sand it lightly to blend it into the surrounding wood.

10. Fill a Gap with Paintable Caulk

Use paintable caulk from your local home improvement store for large gaps that you just want to hide. This caulking comes in a tube and is easy to apply because it requires no mixing or spreading. Just squeeze the caulk into the gap and smooth it with a wet finger. Once dry, paint over it to hide any signs of a repair.

Tips to Prevent Gaps in Wood Table:

Whether made of wood or laminate, Tabletops will warp due to expansive and contractive forces on the material. This is a side effect of humidity changes, which cause the top and air around it to expand and contract as they absorb and release moisture. You can use the following tips to prevent gaps from appearing between boards.

1. Use thermal breaks to separate the slabs in laminate tops. A thermal break is a material that holds together two adjacent pieces of wood or laminate, slowing down their ability to expand and contract across the gap. Such materials include metal brackets, set into both slabs and then attached to the tabletop frame or metal rods.

2. Keep your tabletop in a moderate temperature and humidity range. Warping can also be caused by dramatic changes in the temperature or humidity of an area. For example, if you have an air conditioner that dries out the air, it can cause tops with stained laminate surfaces to warp slightly. Conversely, if an air conditioner is constantly moistening the room’s perspective, this can cause the tabletop to swell slightly.

3. Keep your table covered when not in use. If you don’t have thermal breaks between boards running across your tabletop, it’s still possible to prevent warping by keeping the wood off of an unheated floor or covering it when not in use.


As you can see, there are many ways how to fill gaps in the wood tables. The key is to find a suitable filler for your needs and then use that product as directed on the package. This will help you avoid damaging or doing more work than necessary when filling gaps in wood tables.

The best way is to choose the option that matches your style and budget. No matter what material you use to fill those pesky holes, make sure it’s durable enough to withstand any spills or accidents from family members who might be less than careful!
