How To Fix Air Pockets Under Laminate Flooring

Air pockets may show up if you unintentionally spilled water on your laminate floors. So, how do you remedy laminate floor bubbles? You can accomplish this by blowing out the bubbles, allowing the water to dry completely, adding wood glue, and then polishing the floor. 

Even though laminate flooring is robust and long-lasting, exposure to moisture and temperature variations can occasionally cause the planks to develop bubbles. So, how to fix air pockets under laminate flooring?

A laminate floor with bubbles can be fixed in one of different methods. Each bubble can be cut, allowing the wood’s moisture and air to escape. The area can then be smoothed by dabbing wood glue or laminate floor wax on it.

After that, put a desk or bookshelf there to level it with the remainder of the laminate floor. This procedure is effective for moderate laminate floor bubbling. The floor’s bubbling boards need to be taken out and replaced as the second remedy. This procedure is effective in severe cases of laminate floor bubbling. 

Why is My Laminate Floor Bubbling?

When some areas of your laminate floor start to rise to the seams or top layer of the laminate flooring, this is referred to as laminate floor bubbling. So, why is my laminate floor bubbling?

Moisture is frequently to blame for the bubbling effect, which is especially prevalent at the edges of laminate planks. The fiberwood in that area will swell or pop up when the laminate floor is exposed to sustained moisture for a long time. This is because water will start to seep into the planks through the edges. 

The laminate planks will be constantly exposed to water from spills, cleaning products, and splashes if you leave your laminate floor unprotected in high moisture areas like the bathroom and laundry room. The water will eventually begin to seep into the laminate planks, beginning at the ends and edges. 

When this occurs, the fiberboard at the planks’ ends and edges will swell and get saturated, giving them a soft, bubbly appearance. Water isn’t the only thing that can cause the laminate floor to bubble, though. Your laminate floor may bulge and bubble up if you expose it to corrosive chemicals. The most frequent reason for chemical exposure on laminate floors is using the incorrect cleaning agent. 

Laminate floors can often be difficult to remove stains off without the use of a cleaning solution. The harsh chemicals in some cleaning solutions, such bleach and acids, can easily cause the laminate planks to bubble up or become elevated. The laminate floor’s swelled areas would also look darker or discolored if a chemical spill caused the bubbling. 

Lack of an acclimation or expansion gap during the laminate floor installation is another frequent cause of bubbling and swelling in laminate floors. Manufacturers always recommend leaving little spaces between laminate planks and door and wall frames when installing laminate flooring. This is because laminate floors frequently move and expand on the floor, particularly in the first few days following installation. The laminate floor sets well on the floor because of the movement and expansion.

Will The Air Pockets Under Laminate Floor Disappear Over Time?

With laminate flooring, you may experience the classic elegance of wood floors without having to spend a lot of money. Although there are many different types of laminate flooring materials available, the most are strong and often function well for many years. Will the bubbles on your laminate floor disappear over time?

Yes. Your laminate floor’s bubbles may eventually go away, but only if water damage created them in the first place. The bubbles will disappear or flatten as the water in the laminate board dries. You should be aware that the bubble will still leave a soft, wrinkled place on the laminate floor even after it has vanished. The only option to totally conceal the bubble is to cover it with laminate floor polish and wood glue.

Over time, bubbles on laminate floors frequently vanish. This typically occurs when water spills or moisture damage created the bubbles. The laminate floor’s inflated areas are here filled with water and air. Therefore, the bubbles will reduce and eventually vanish when the water from the wood evaporates. 

The place will still be noticeable, though, because there will be creases where the bubbles formerly were. This happened because the wood was stretched to make room for the water when the laminate plank became saturated. As a result, the wood will seem wrinkled when the water has evaporated and it has become dry because of the expansion it underwent to make room for the water. 

Therefore, in a technical sense, the bubbles vanish but leave creases on your laminate floor. You’ll need laminate polish and wood glue to get rid of the wrinkles. 

Additionally, you should be aware that the bubbles won’t go away over time if they were brought on by something other than water damage, such as poor subfloor preparation or a lack of an acclimation interval. This is due to the fact that you have not addressed the bubbling’s root cause.

How To Fix Air Pockets Under Laminate Flooring

On a laminate floor, bubbles can be repaired in a variety of methods. The technique you’ll employ is determined by the origin of the bubbles and the degree of the laminate boards’ damage. No need to panic; this section will demonstrate some simple methods for repairing bubbles in laminate flooring. 

Popping the bubbles is the first step in repairing bubbling in your laminate floor. For this technique, you’ll need to lay a rag or piece of cloth over the bubble and then slice through the bubble with a sharp object. This will allow the bubble’s air and moisture to escape, damaging the laminate floor. 

Then, use wood glue to cover the gap and a putty knife to smooth it out. Applying laminate polish or wax to the smooth, dry laminate floor will help disguise any blemishes. After that, flatten the impacted area by setting a desk, dresser, or bookshelf there. 

Taking out the damaged or bubbled planks and replacing them with fresh planks from the same set is the second method for repairing bubbles in your laminate flooring. The good news is that this procedure fixes bubbles in every circumstance even though it takes time and effort. Additionally, using this technique enables you to examine the baseboard and subfloor surrounding the laminate floor to identify any issues and learn how to address them in the future. 

Only when there is no expansion gap on the floor as the reason of the bubbling should the last procedure be applied. Examining the floor should come first. The laminate boards don’t have enough room to move if you find that they are pressing up against the door frame or wall strongly. Therefore, you must make an expansion gap. 

Start by taking down the trim and baseboards from the bottom walls. The laminate floor’s edges should then be trimmed with a power saw to remove any lengthy pieces. As a result, there will be a space between the planks and the wall. Then tap the planks to the floor with a rubber mallet. Before putting the baseboard trimmings, give the floor a few days to expand.

Can You Repair Bubbles on Laminate Floor Without Replacing The Floor?

A bubble in the flooring could be a sign of an issue with the installation or the relative humidity in your house. The air pockets that develop beneath laminate flooring are known as “peaking.” Can you repair bubbles on laminate floor without replacing the floor?

Yes. If the laminate planks are still in good shape, you can fix bubbles on a laminate floor without replacing the whole thing. If the planks are simply wet and bloated, drying them out will allow you to fix the bubbles. You don’t have to replace the laminate floor in this situation. 

To fix the bubbles, however, you must replace the laminate planks if they are damaged, discolored, or wrinkled. This is because the laminate planks in this instance need to be replaced after being damaged. 

Examine the laminate planks to determine whether the laminate floor needs to be replaced. To minimize the bubbles, you don’t need to replace the floor if the boards are still sturdy and robust. Simply address the origin of the bubbles, then wait for the planks to dry. 

It is recommended to replace the floor if the laminate planks are damaged or have numerous bubbles because those planks are not sturdy enough to be on a floor. Injuries, mold growth, and floor gouges can result from leaving damaged laminate planks on your floor.
