Insight – By applying a wood hardener, you can ensure that the fibers of your wood are strengthened and protected against any future moisture damage. Simply follow the instructions on the bottle and enjoy the peace of mind of knowing your wood is well-protected.

Assessing the Water Damage on Your Coffee Table

The first thing you’ll want to do is check how much damage was actually done. Was it a small spill that soaked into the surface, or did your clumsy cousin dump an entire water pitcher? Assess the wood for signs of warping, swelling, or staining.

Checking for Warping and Swelling

Run your hands along the tabletop’s surface to feel for any uneven, bowed, or rippled areas indicating the wood has warped. Check that the legs and edges are still straight and secure. Swelling usually appears as raised grain or small bumps across the surface. If warping or swelling is minimal, the table may return to its original shape as it dries.

Looking for Water Stains

Water stains range from light discoloration to dark blotches, depending on the type of wood and the length of time the water sat. Stains often become more noticeable once the wood is dry. Unfortunately, water stains can be difficult to remove completely. You may need to sand out and refinish the entire tabletop. It’s time to take action before the water does any further damage. The following steps focus around absorbing any remaining moisture, stabilizing the wood, and protecting the finish.

Supplies You’ll Need to Fix Water Damage on a Wood Coffee Table

To fix water damage on your table, you’ll need a few supplies.

Wood filler

You’ll want to fill in any cracks, holes, or gouges in the wood. Look for a wood filler that closely matches your table’s natural tone. Apply with a putty knife or spatula and sand smooth when dry.


You’ll need varying grits of sandpaper (around 220, 400, and 600) to sand out water stains and rough areas, then smooth the surface. Be sure to wipe away dust with a tack cloth before applying sealers or stains.

Wood Sealer or Stain

To protect the wood from future water damage, apply 2-3 coats of polyurethane sealant or wood stain. For a natural look, choose a sealant with UV protection. For darker wood tones, oil-based stains work well. Remember to wipe away any drips or uneven areas between coats.

Use a high-quality paintbrush to apply the sealers and stains. Foam brushes can leave bubbles. Don’t forget to clean brushes in between product uses with paint thinner.

Rags & Tack Cloths

Have rags, tack cloths, and paper towels on hand to wipe away spills, drips, and dust during the repair and refinishing process.

Eye Protection

Wear eye protection gear like safety goggles when sanding wood and applying chemical products to avoid irritation.

Insight – Revive the damaged wood by applying a wood conditioner or oil. This simple step helps the wood fibers absorb moisture and regain their original shape. Take your time to massage the conditioner into the wood using your fingers and see the magic happen!

Repairing Water Stains and Discoloration

Once you’ve dried the tabletop and tightened any loose joints, it’s time to deal with any water stains or discoloration. There are a few methods you can try to restore your table’s surface.

Sanding out Stains

For light stains, you may be able to sand out the damage. Use fine-grit sandpaper (around 220 grit) and gently sand over the stained area using small circular motions. Wipe away dust with a tack cloth and check your progress. Re-stain the sanded area to blend in with the rest of the tabletop. You may need to sand and re-stain a few times to fully restore the surface.

Bleaching White Stains

If water leaves white stains or rings on your coffee table, bleach can help lift them. Make a solution of 1 part bleach to 3 parts water. Wearing gloves, apply the solution with a cloth to the stain and let sit for 2-3 minutes. Rinse with water and wipe away. The wood under the stain may be lighter, so you’ll likely need to re-stain the area to blend in the color. Test the bleaching solution in an inconspicuous area first to check for colorfastness.

Insight – Use a dehumidifier or desiccant packs to ensure that your table remains pristine. Placing them in the vicinity of the table can effectively draw out any excess moisture that may be trapped within the wood, safeguarding it against potential damage.

Use Wood Filler to Repair Deep Gouges and Holes

Once the water damage has been addressed and the table has dried completely, you’ll want to repair any deep scratches, gouges, or holes in the wood. For this, you’ll need wood filler, which comes in a paste form that can be sanded and stained to match your table.

Find The Right Color

Wood filler comes in a variety of wood tones, so find one that matches your table. You may need to mix two similar shades to get the right match. Be sure to test the filler on a discreet area of the table to check the color match before applying it to damaged areas.

Apply the Filler

Use a putty knife or wood filler applicator to spread the filler over damaged areas. Press down firmly so it adheres well. Let it dry as advised, usually 3 to 5 minutes. Then, use a sanding block and fine-grit sandpaper (around 220 grit) to sand the filler smoothly and even with the surface of the wood and wipe away dust with a tack cloth.

Seal & Protect

Once sanded, apply a sealant like polyurethane or lacquer over the wood filler and the entire tabletop. This will protect the wood and give you a smooth, durable finish. You may need to apply 2-3 coats, letting it dry in between. The sealant also helps the wood filler blend in better with the natural wood.

Refinishing Your Coffee Table to Prevent Future Water Damage

Now that the water damage is repaired, it’s time to refinish your table to safeguard it from future water damage and spills. Refinishing will also restore your table’s appearance.

Sanding the Surface

Lightly sand the entire surface of the coffee table with fine-grit sandpaper (around 220 grit) to rough up the existing finish and provide “tooth” for the new finish to adhere to. Wipe away dust with a tack cloth.

Applying a Sealant (optional)

For added protection, you can apply a sealant, such as polyurethane, to the sanded surface. Water-based polyurethane is easy to apply and dries quickly. Apply 2-3 coats, waiting 2 hours between coats. Sealants protect the wood from water penetration and scratches.

Choosing a Finish

To refinish your table, pick a water-resistant finish, like lacquer, polyurethane (as above), or water-based acrylic. Lacquer and polyurethane provide the most durable protection but have strong fumes. Water-based acrylic is water-resistant, has a low odor, and dries quickly. Apply 2-3 coats of your chosen finish, waiting 2-4 hours between coats.

Maintaining Protection

To protect your table from water damage, wipe up spills immediately, use coasters for drinks, and avoid placing the table in direct sunlight or near heating vents. Reapply an additional coat of your finish every 1-2 years or if water no longer beads up on the surface. By refinishing and routinely maintaining your coffee table, you’ll prevent water and other damage from threatening its longevity again in the future.
