How Does Water Damage Laminate Flooring? Water damages laminate flooring by soaking into the layers. Once inside the boards, it causes them to swell and warp. It also weakens the glue that holds them together and they can eventually fall apart.
While laminate flooring isn't necessarily ruined if it gets wet, damage to the laminate can occur within two to four hours of water getting under the boards and can progress quickly.
Water damaged boards can't be fixed, but they can be replaced. If you have leftover laminate flooring boards from your original installation, use those. If not, match the damaged boards with new ones. Make sure the floor is completely dry before you begin the repairs.
When your laminate flooring gets saturated with water or any liquid, the planks will start to bend and buckle. It would make your laminate flooring look hideous and it would become more damaged over time if you ignore it.
Will Wet Laminate Dry Out on Its Own? Although wet laminate flooring will eventually dry out, it can take weeks to do so on its own. Not only does this increase the risk of mold, but it's also likely the floor will start to fall apart too.
In both of these cases, if your answer is yes, then you're looking at an unstable structure that is quite dangerous, and warrants an immediate call to your laminate floor installers. When water gets trapped under the boards, it creates a dark, moist environment that's ideal for the growth of mold.
It takes only 24 -48 hours for mold to grow under wet laminate.
If your laminate flooring was glued down, the source of the swelling may not be caused by moisture. After gluing, the joints of the boards may swell slightly as they absorb the water in the glue. This is temporary and often resolves itself in three to four weeks.
Fear not! Moisture under your laminate flooring can be treated. Whether your floor got wet from a leak or your floor was flooded, you can prevent mold from growing and repair your laminate flooring. Wet floors can swell or warp, but you can fix water damage in most cases.
The main cause of bubbling in laminate floors is moisture although it may also be caused by poor quality flooring or the lack of an expansion gap. It can easily be fixed by using wood glue, replacing the entire surface (in the case of widespread damage), or cutting an expansion gap.
Soak Up as Much of the Water as Possible
Towels, mops and clean rags can immediately soak up small puddles and spills. Use a wet vacuum to pull up larger water sources from out the flooring. Don't stop using the wet vacuum even when you can no longer see the water on the surface of the wood.
If you have water damaged subfloors, you'll likely notice your floors are swollen or lifted. They may also feel soft or squishy when stepped on. The best choice for damaged subflooring is usually to have it replaced — especially if it is growing mold.
Laminate flooring can take small, everyday spills on top of the flooring without seeing any water damage. However, if laminate takes on as much water as a major leak or flood, the flooring will resist water damage for only 2-4 hours. By the 5th hour submerged, laminate will start to swell and be irreparable.
Moisture on your laminate flooring can cause mold, which is not only unattractive, but can irritate allergies if left unattended. If you notice mold stains on your flooring, use nonabrasive, antimicrobial chemicals to clean the mold away without damaging the laminate floor.
Because laminate is a dense fiberboard, it takes over two full days to dry. Installed laminate flooring may take weeks to dry, if ever. After complete drying, the laminate flooring will never return to its original dimensions.
Run the hair dryer along the swollen flooring until you start to see it contract. Then, use a roller or straight edge to flatten it out. If the piece of laminate starts to swell even more while drying it, you will need to replace it.
As the temperature rapidly changes from cold to hot and back again, your laminate flooring expands and contracts, resulting in curling, peeling and other forms of damage. Making sure that your laminate flooring makes it through the winter is easier when you avoid these sorts of large temperature changes.
A water-damaged subfloor feels spongy underfoot. It might bounce or squeak when you walk across the room. Sagging boards, damp spots and unpleasant musty smells are also signs of a rotting subfloor.
To keep your laminate floors fresh, mop them every two months. Damp mops (a.k.a. microfiber mops) are gentle enough to use on laminate floors. If you're going to use a regular mop, just wring it out until it's almost completely dry.
Laminate floors need to be swept or vacuumed often to keep them clean. Dirt is an enemy to laminate since it scratches and dulls the finish of the floor. However, sweeping or vacuuming improperly can do more damage to your laminate than the dirt.
Things like having multiple fans and dehumidifiers can speed up the process, but generally, you're looking at anywhere from 24 to 96 hours for your subfloor to dry out completely. You won't want to rush this process, because the goal is to remove all of the moisture so that it can't cause any further damage.
Minor bubbles can be fixed by “bursting” them. Place a damp cloth on the bubble and cut a slit on the bubbled area using a sharp knife. Squeeze wood glue into the slit you have opened and press the veneer down. Place a weight overnight so that it is entirely flattened.
Depending on the quality of the flooring, laminate flooring can last between 15 to 25 years on average, or longer. Choosing the right flooring for your home is about more than just aesthetics, it's also about durability and strength.
