What Will You Need?

In order to fill gaps in the wood plank table, you will need the following:

  1. Caulk or wood filler
  2. Sandpaper
  3. Wood shims
  4. Paintbrush
  5. Vacuum cleaner
  6. Paint or varnish (optional)

Depending on the gap’s size, you may also require other items such as a chisel, drill bit, and saw for cutting out larger chunks of wood. Be sure to read the instructions carefully before starting your project.

10 Easy Steps on How to Fill Gaps in Wood Plank Table

1. Clean the Area:

Using a Vacuum Cleaner

Using a vacuum cleaner or shop vac, remove any dirt, dust, and debris from the gaps between the planks. Be sure to get all sides of the wood plank table. If there are particularly stubborn spots, use a damp cloth to remove them. Try to avoid using too much water.

2. Measure the Gap:

Once you’ve cleaned up, use a ruler or measuring tape to measure how much gap you need to fill in order to make it level with the rest of the surface area. Don’t forget to take into account how wide the gap is, how deep it goes, how long it runs, and how much room you will need to fill it up. Use this measurement as your baseline for the rest of the steps.

3. Prepare Your Wood Filler:

If you’re using wood filler, mix as directed on package instructions and apply liberally to each gap. Wipe away excess with a damp cloth and allow it to dry completely before continuing. If you’re using caulk, be sure to press it into the gap securely and use a damp cloth to remove any excess. Otherwise, wood shims can build up the gap and create a level surface.

4. Apply Caulk:

Use a Caulking Gun to Apply

If you’re using caulk, use a caulking gun to apply it to the gaps. Use your finger or a putty knife to smooth out and ensure you’ve filled in the entire gap. Don’t forget to clean up any excess with a damp cloth. Use a hair dryer to help it set faster.

5. Sand the Area:

Using sandpaper, lightly sand away any excess caulk and wood filler until it’s completely level with the rest of the surface area. There should be no bumps or ridges. Because wood is soft, start with coarse sandpaper and work your way up to finer grits. It will take some time, but the results will be worth it!

6. Add Wood Shims:

If there are still some large, noticeable gaps left over, add wooden shims as support for a more seamless look. Try to find a color that matches the wood grain as closely as possible. For example, if your wood plank table is made of pine, look for light-colored shims to match it.

7. Apply Stain:

If desired, you can stain or paint your wood plank table to give it an even more unified look! Be sure to adhere to any instructions on how to use the product. If you’re using a water-based stain, make sure to wipe away any excess and dry it thoroughly before varnishing.

8. Apply Varnish:

Varnish is a great option if you want to completely seal your wood plank table and protect it from moisture and dirt! Make sure to follow the instructions included with your varnish product. Another option is to use a polyurethane sealer that can be wiped onto the wood in thin layers. It’ll give your wood plank table an even more polished look.

9. Clean Up:

Once your project is done, vacuum up any dust and debris left over from sanding. Additionally, remove any excess caulk or wood filler with a damp cloth. This step is especially important if you’re using a water-based stain or polyurethane sealer.

10. Enjoy Your Newly Filled Gaps:

You’re all done! Now sit back, relax, and enjoy how beautiful your newly filled gaps look on your wood plank table! Remember always to be careful when handling tools and materials – safety is key! If you ever need more advice on filling gaps in wood plank tables, consult a professional carpenter or handyman for assistance.

By following these ten easy steps, you can have a beautiful gap-free wood plank table in no time. With the right tools and supplies, you can quickly and easily fill any gaps. Enjoy your newly filled gaps!

5 Additional Tips and Tricks

  1. Use Wood Filler: Applying a layer of wood filler to the gaps in your plank table is an easy and effective way to fill them. You can purchase premixed wood fillers or make your own by mixing sawdust with white glue, which will help match the surrounding wood’s color and texture.
  2. Use Dowels: Dowels are cylindrical pieces of wood used in various construction projects, such as cabinetry and furniture making. To fill gaps in your plank table, you can insert some wooden dowels into the gap and then secure them with an adhesive or nails. This method is quick and simple but may not be as aesthetically pleasing as other methods.
  3. Choose a Larger Piece of Wood: If you don’t want to fill the gaps with filler or dowels, you can purchase a larger piece of wood and cut it down to size. You can then fit the larger piece of wood into the gap, which will give your table a much cleaner look.
  4. Use Pocket Screws: Pocket screws are small metal fasteners with a pointed end and are great for filling gaps in wood plank tables. They are easy to use and require no additional material like glue or nails. Just make sure that the screws are slightly smaller than the gap, so they don’t protrude outwards.
  5. Use Epoxy: Epoxy is a strong adhesive that works well for filling gaps between planks on tables. It’s easy to apply and won’t require any additional hardware. The epoxy should be applied evenly across the gap to ensure that it doesn’t become visible once dried.

These tips and tricks will help you fill any gaps in your wood plank table, giving it a much cleaner look. With a little bit of time and effort, you’ll be able to achieve a professional-looking finish for your furniture without having to replace the entire piece.

5 Things You Should Avoid

  1. Avoid using too much polyurethane, as it can fill the gaps and create a seal.
  2. Don’t try to force small pieces of wood into the gap, as it won’t provide a secure fit.
  3. Avoid using glue alone unless you’re gluing thin pieces of veneer over the gap instead of using larger filler material.
  4. Don’t use nails to fill gaps because they will be visible and may cause splintering or other damage when knocked out of place.
  5. Refrain from sanding too much since this can make the surface uneven and create more problems than it solves.

If your wood plank table has some gaps, there are several ways you can fill them in without causing further damage or making a mess. Using the right materials and techniques will ensure that your repairs last for years to come. With some patience and attention to detail, you’ll be able to make your repairs look great!

Can You Use Silicone to Fill Gaps in Wood?

Silicone is a great option for filling gaps in the wood, as it forms a strong, waterproof bond that won’t easily be affected by moisture. It also acts as an adhesive, so you don’t have to worry about the filler material coming loose over time.

To use silicone, first, ensure the gap is clean and dry before applying the sealant with a caulking gun. Allow enough time to set before sanding the surface for a smooth finish.

Additionally, you can use a silicone-based wood filler if you want to color-match the gap.

This type of product is available in both premixed and colored versions, so it’s easy to find one that will blend in with your furniture.

Using silicone to fill gaps in wood is an effective solution for sealing up cracks and preventing moisture from entering your furniture. With the right materials, it doesn’t have to be difficult or time-consuming – just remember to follow all instructions carefully!

What is the Strongest Wood Filler?

Epoxy resin is the strongest wood filler available and also happens to be one of the most versatile. It’s incredibly durable, waterproof, and able to withstand extreme temperatures.

Its adhesive qualities make it ideal for filling large gaps or repairing cracks in furniture and other wooden items.

Epoxy resin comes in two components: a resin and a hardener that must be mixed together prior to use. Once fully cured (which takes about 24 hours), epoxy can be sanded down and painted over for a seamless look. This type of wood filler is often used for structural repairs such as cracked boards or broken joints.

Such as Cracked Boards

Overall, epoxy resin is the best choice when you need a strong, long-lasting wood filler that won’t be affected by water or extreme temperatures. With a little bit of preparation, you can use epoxy to fill gaps and restore your wood furniture for years to come!


In conclusion, repairing a wooden plank table is not complicated if you break it down into the distinct steps of removing the old planks, measuring, and cutting new ones to fit. The most important thing of all is to get creative!

Wooden plank tables offer a unique aesthetic that resembles rustic charm. However, with modern methods like using biscuit joiners and dowels for increased stability, rustic chic tables can be as sturdy as any you would find in any high-end store.

Taking inspiration from other furniture pieces or interiors in your home is also helpful to see how to perfectly bring your new project together into one cohesive piece of DIY decor.
