Laminate flooring is made using sections that are interlocked. This makes it easy to perform repairs in the event of water damage. To perform repairs, start by drying the wet area. Then begin removing the damaged parts. Before installing new sections on the floor, make sure its surface is completely dry.
There are a number of reasons why kitchen and bathroom floors become flooded. The most common causes include a leaky dishwasher, refrigerator, washing machine, or another source of moisture penetration.
If you suspect water damage, you should first identify the source of the leak, then fix it immediately. You could start by clearing the water on your floor. Of course, without closing the leak first, this will not do much good.
Once the source of the leak has been dealt with, proceed to remove wet parts of your laminate floor. Give it time to dry out. To speed up the drying process, use a wet-vacuum or mop to absorb the water. The method you use may depend on the volume of water spilled and whatever tool is available to you. Ideally, a wet-vacuum should be used to clear a large amount of water.
When all the water clears, the floor will still be wet and will need to be left exposed for a while to dry. Put a fan on the floor to speed this process up. Sections of the floor that have been damaged may require removal using a crowbar or circular saw. To remove the damaged parts without damaging the areas on the surrounding floor, you can use a chisel and hammer. The part of the floor under the damaged section(s) is softer and should be scraped with a sharp edge such as a knife or a similar tool. When you replace sections of the floor use construction glue and make sure each piece fits perfectly before moving on to the next one.
