Wood tables add warmth and character to our homes, but they require proper care to maintain their beauty. Water damage is a common problem that can significantly affect the appearance and durability of wooden table tops.

So, is your wood furniture facing those issues like swelling, warping, discoloration, or mold growth? Here are the 7 primary reasons that lead to wood table water damage bubble, but not limited to:

1. Spills not cleaned up immediately: Drinks, soups, or any other liquids spilling on wooden tables were supposed to be wiped right away. The liquid can then soak into the wood. Even little spills that look innocent to a person can cause damage if you ignore them for a long time.

2. Water rings from glasses and mugs: Hot and cold drinks create some degree of condensation. So, if you’re placing any glass or cup directly on the wooden table (without a coaster), it will cause moisture to stain the table with rings that never come out.

3. Too much humidity: Too high a humidity rate in your home lets wood suck the moisture out of the air. Over time, this would induce swelling and warping in the table tops, especially in places like bathrooms, kitchens, or damp basements.

4. Direct contact with plants and flowers: Are you putting flower vases, potted plants, or even wet plants directly on the wood table surface? Then, no wonder that it traps moisture on the table. Water can leak or seep from the bottom of containers without you even noticing.

5. Bad cleaning methods: If you’re using too much water or cleaner when wiping, you’re definitely damaging your wood furniture. Soaking the tabletop with moisture can ruin the protective finish.

6. Steam and heat: Hot items like steaming food dishes placed directly on wooden surfaces can force moisture into the wood as steam condenses. This is particularly damaging to the finish and underlying wood.

7. Temperature changes: Quick changes in temperature can cause wood to expand and contract. They create small cracks where moisture can enter and cause damage over time. Besides, rapid changes in temperature also lead to cracks and splits in the wood table top.

• Move the table to a warm, dry room with good air flow
• Open windows on dry days to improve circulation
• Use a fan nearby to help move air around the table
• Place a dehumidifier in the room if you have one
• Remove any drawers to allow better air movement
• Put silica gel packets (like those found in new shoes) on and around the table

Important note: Do not use hair dryers or heaters directly on the wood. They can cause cracking or warping. Therefore, patience is key during this step.

If white and dark water marks remain on your table top, you can try 4 simple methods below at home to remove them.

For white water marks:

1. The iron method: This is one of the best methods for how to fix water damaged wood table top. Here is the process:

• Set the iron to low heat with the steam function turned off (or the last thing you want is more stains from moisture and heat).
• Place a clean, slightly damp cloth directly over the water marks
• Slowly move the warm iron in circles. Don’t keep the iron in one place too long.
• Every 5-10 seconds, you should check the table top by lifting the cloth.
• Keep doing this until the water stain fades away.

2. Mayonnaise: Strange, yet effective! You can spread a tablespoon of mayonnaise on the stain. Leave it overnight, and then you wipe it clean the next morning.

3. Oil and Vinegar Mix: Another option is to mix equal parts olive oil and vinegar. You can apply this mixture with a soft cloth. Rub it in the direction of the wood grain until the white ring disappears.

4. White toothpaste: Regular non-gel toothpaste can also remove watermarks. First, you can apply a small amount of toothpaste to the stain. Gently rub it in using circular motions. Finally, you need to wipe the area clean with a damp cloth.

For dark water marks on wood table:

Sometimes water sits on table surface for too long. It seeps past the protective finish and into the wood. This often happens with leaky planters. The damage can go unnoticed for months. So, the result of water damaged wood table top is usually a dark brown or black ring.

Unfortunately, an iron won’t fix this. Dark water stains are harder to remove. However, toothpaste often works. Below is how you can fix dark brown or black ring on table top:

• Apply a small dab of toothpaste
• Gently brush the entire stain
• Do not press too hard or scrub too long. Scrubbing too much can remove the wood finish.

Note: Sometimes, the stain won’t fully come out. If that happens, you may need to sand the whole surface. (We’ll cover this in Step 4.)

Not only are there watermarks, but there are also bubbles on your furniture. You might wonder, "How to fix water damaged swollen wood table?" or even "how to repair wood table water damage bubble?" We’ve got the answers in Step 3. Don’t skip it!

Step 4: Fix Wood Table Water Damage Bubble

Time needed: 15-20 minutes

All we need to do now is release trapped air and moisture from the surface.

• First, it’s important to cut along the grain with an X-Acto knife or utility knife. Make a small cut with the grain of the wood over each bubble. The cut allows the trapped air or moisture to come out. Please note that you should cut only through the finish and not deep into the wood.
• Next, put a damp cloth over the affected area. Ensure the cloth is wet but not dripping. Then, you need to place the iron on medium heat without steam. Lightly press that iron on the damp cloth and begin pressing with circular motions for about 30-45 seconds.
• At the end, you take away the damp cloth and observe. The heat and moisture from this should help the finish to re-bond with the wood. Should there be bubbles still visible, you can repeat the procedure.

From here, we will move to step 4, which explains proper sanding techniques for table. The sanding process will create a smooth finish on your repaired wood surface.

Step 5: Sand the Water Damaged Area on Wood Table Top

Time needed: 30-60 minutes

After you’ve completely removed all bubbles on table top, you'll need to smooth the damaged surface. First, please choose fine sandpaper with 220 grit or higher.

Now, we begin by sanding the damaged area gently. As a general rule, you need to move the sandpaper in the same direction as the wood grain. Then, please use light pressure as you work.

Your goal is to smooth the surface, not remove too much wood. When you finish, don’t forget to wipe away all dust with a clean cloth.

Here's a down-home tip: If the water damage is more serious, medium sandpaper around 150 grit first is a must. After the first pass, you can switch to the finer 220 grit for the final smooth finish. This two-step approach is best for deeper stains or rough spots. Not optional, but if you have a random orbital sander, better to use it to save time, effort, and your back.

Step 6: Condition the Wood

Time needed: 1-2 hours

Once your table top has been finely sanded smooth, it’s time to feed the wood. The sanding process dries out the water damaged wood table top, so conditioning helps restore its natural moisture balance.

• Choose a high-quality oil made for furniture that is of the same kind as your table wood.
• Then, you pour a little on a clean soft cloth (or paint brush, small roller), and start application on the table top. Of course, you still have to follow the wood grain.
• Use small circular motions, gently working the oil deep into the fibers.

Next, you can let the oil soak into the wood for 15 to 30 minutes. During this time, the wood takes up the full measure of conditioning. You will see it getting slightly darker as it drinks in the oil.

With a second clean cloth, wipe off all the oil that did not soak in. The wood then should look refreshed but not too wet or shiny clean. Now that the wood is conditioned, you can wait for it to dry before continuing with the last step.

Step 7: Refinish the Water Damaged Area

Finally, you need to choose a protective finish that matches your table usage. We highly recommend polyurethane, which can provide excellent durability for dining tables that get heavy daily use. Not to mention, the subtle amber tone also warms up most wood types nicely.

A microfiber mini roller works best for applying polyurethane when refinishing a water damaged table top. You must work quickly with polyurethane on large surfaces before it becomes sticky. These rollers make the job faster and almost mistake-proof.

Do not worry about bubbles when you first apply the finish. They disappear within minutes and leave a smoother surface than a brush can achieve.

You should apply at least three coats of polyurethane on the table. Thicker protection reduces the chance of damage to the wood underneath. Your table will look great for a longer time. When you need to refresh the finish later, the process will be much easier.
