How do you fix a crack in a wood table top?

Whether you’re looking to repair a small crack or fill in a large hole, this guide will walk you through the process of repairing your table top with wood filler.

Can you repair a cracked wood table top?

If you’ve got a large crack in your wood table top, your best bet is to replace it. With the exception of small surface cracks or scratches, large cracks will make your table look old and worn out. However, if your table top has a small crack that isn’t deep (you can see through it to the other side), it can be repaired with wood filler.

You’ll need some sandpaper and an electric drill with a bit that’s 1/16th inch smaller than the width of your screwdriver shaft so you can use that as an extension for drilling holes into the tabletop. Fillers come in two different types: epoxy and polyester-based putties like Bondo® auto body filler products (available at any auto parts store).

For this particular repair project I chose Bondo® automotive body filler because it was available locally at my local hardware store — but there are many other options available online if you prefer not to use automotive products around food items!

How do you repair a split wood table top?

  • Epoxy wood filler. This can be used to fill large cracks or holes in the wood. It’s very strong and durable, but it’s not as flexible as some other materials and may crack over time if you don’t use it properly.
  • Wood glue. Glue is one of the most common ways to fix a broken tabletop, because it works well in many situations and is easy to apply without requiring any special equipment (just an old toothbrush or paintbrush).
  • Spackle compound. This is another good choice for repairing small cracks or splits in your table top, as long as they aren’t too wide—you’ll probably have better luck with spackle compound than with epoxy filler on wider cracks!

How do you fill a cracked table top?

  • Mix the wood filler with water to create a thick, but not pasty, consistency.
  • Apply the mixture onto the crack or chip and let it dry for about an hour before sanding it down with fine-grit sandpaper. Don’t worry about getting rid of all of the old finish; just make sure that you’ve removed any parts of the old finish that might prevent your new finish from adhering properly.
  • Apply at least two coats of polyurethane or varnish over top (keep in mind that you’ll need to sand between coats).

How do you fix hairline cracks in wood?

Hairline cracks in wood are caused by the expansion and contraction of the wood as it heats up and cools down. To fix them, you’ll need a paintable silicone caulk to fill the crack. Before applying this filler, use a putty knife to smooth out any bumps or dips on the surface.

Then apply a thin layer of silicone caulk over the entire area with your finger or a small spatula. Let dry for 24 hours without sanding it first. Sand once dry with fine-grit sandpaper before painting your piece again using primer and paint designed specifically for outdoor furniture (available at most home improvement stores).

What is epoxy wood filler?

Epoxy wood filler is a resin-based substance that’s made of epoxy resin and a hardener. When mixed together, they cure to form a strong bond that can be used as a filler to repair cracks in wooden furniture. Epoxy wood filler is waterproof and is good for filling cracks because it won’t shrink or warp when it dries out. It can also be sanded, stained, and painted over once it has dried completely.

If you have large cracks on your tabletop, then epoxy wood filler might not be the best solution for you since it does not offer enough flexibility when applied on large areas like tables or countertops where there are multiple pieces of wood glued together (such as chair legs).

In this case, using an adhesive like Titebond III would be better suited because it will fill up the gaps between each piece of oak veneer while also allowing them to retain their shape once they dry out again after being glued together with clamps

How do you fill wood cracks before staining?

If you want to fill the cracks with wood filler that matches the color of your table top, or if you want to use a colored stain on your tabletop and then sand off some of it before applying another coat, you will have to use a filler that can accept stain.

If you choose to fill the crack with colored wood filler, pick one in a close enough tone for your table top so that it won’t look out of place once it’s applied.

Use an old paintbrush or cotton swab dipped in lacquer thinner and gently apply the filler over top of each crack using smooth strokes. Wipe off any excess before it dries so as not to leave streaks behind when sanding later on down the road!

Why do wood tables crack?

There are many reasons why wood tables crack, but the most common are shrinkage, stress, and moisture.

Shrinkage is caused by drying the wood improperly or unevenly. It can also occur if the table isn’t finished properly after it’s been sanded and stained. In these instances, stress causes a crack to form along with natural weaknesses in the grain of your table’s surface.

Moisture is another common cause of cracks in wood tables because it weakens the glue holding its pieces together.

To prevent cracking from moisture exposure, keep your table away from heat sources like radiators or fireplaces and make sure to store it outside during winter months so that snow doesn’t pile up against its legs and cause water damage (which leads us back full circle).

How do you use wood filler?

The first step to using wood filler is to apply the filler. A putty knife is a good tool for this, as it allows you to spread out the filler and also smooth any lumps or irregularities in the affected area.

Once you’ve applied your fillers and allowed them to dry, sand down any excess material that might have been applied by mistake. This ensures that your table top is even with no raised spots where you can still see traces of damage underneath.

You can then stain your table top using whatever color(s) fit your decor needs best!


To conclude, wood filler is a great way to repair cracks in the wood table top, but it’s not the best solution.

The filler will last for some time, but if you have other plans or just want to get rid of the crack as soon as possible, you should consider using epoxy glue instead. It’s stronger than filler and can be used on both wet and dry surfaces.
