How Does Humidity Affect Laminate Flooring?

Damage Signs

• Damage from humidity first manifests itself as either a small raised edge in between laminate planks, or as a bubble somewhere on the plank. These changes can be hard to notice, so inspect your floor thoroughly if you suspect damage from humidity. The best way to do this is to run your fingers over each seam and feel for any irregularities. If damage is left unchecked, small bubbles can turn into large bubbles, and seams can begin to inflate, causing separation of planks. In the most extreme cases, laminate planks can warp and twist into unusable shapes.

Slowing Humidity Damage

• The key to dealing with humidity damage is to catch it as soon as possible and to take steps to slow and/or reverse it. The easiest thing you can do is to control the humidity by using a dehumidifier to lessen the humidity in the affected room. Clean up any liquid stains as soon as they occur to prevent the damage from worsening. Although there is no true way to reverse damage caused by humidity, continuous monitoring and regular use of a dehumidifier may cause bubbles to shrink. However, they will not disappear entirely.

When to Replace

• Although a few small marks or bubbles may not be very noticeable, if you see large bubbles starting to form, or have noticed the laminate plank separating from the rest of your floor, you will need to replace it. After you have removed the damaged plank, clean up any moisture that could cause further problems. Purchase a new plank and have it installed by a flooring specialist. If you remember where you purchased the laminate floor, you may be able to get the labor done at low or no cost as a "repair" installation.

Preventing Future Damage

• In order to protect your floor from damage from humidity, there are several key things you can do. First, closely monitor the humidity levels in your home, and adjust your habits accordingly. If you live in a humid area, keep your windows closed and run a dehumidifier regularly. There are also chemical products you can use around your home to lessen humidity. In addition, keep your floor clean, and always dry it after mopping.
