Laminate floors are great for heavy traffic areas such as laundry rooms, mud rooms, children's play rooms offices with rolling chairs. These floors are NOT......NOT for rooms that could have even the possibility of having water on them, a laminate floor is made up saw dust (particle board) and glue once it absorbs water it swells like a sponge and doesn't go back to it's original position, solid wood for the most part will expand and contract in many instances back to normal. With laminate flooring it's not the top surface that of the product that the water penetrates it's the seams, the older laminates had a glue that helped to some extent but now most manufacturers are using the Non glue/T&G styled interlocking system so there is nothing but bare wood in the seams. after many lawsuits the laminate market has diminished 50% because of this problem, BTW the mat is fine for the front of the tank I just keep 5 towels on the side of mine, again just to reiterate to all reefers that if you have a 100 gallon tank break in the middle of the night (on your solid wood floors) don't panic, even if it takes you an hour to clean it up your floors will take it, here are a few things you can do:
1. If it's in the middle of the night call a water recovery company, or clean-up emergency service.
2. If during the day use all the towels you have and get the water off the floor or use a wet dry vacuum, if you don't have one buy one there cheap to have on hand, you can even rent one (yes you do have small but doable window of time).
3. Open all the windows and Rent a commercial fan run it for 1 to 3 days, it may seem dry but the water is under the boards in some areas, Do NOT use heaters, this will only cause more damage to the flooring by drying them out too quickly.
4. Remove the baseboards, the water IS behind them and the fans cannot do there jobs to dry them out unless you remove them.
5. If you feel fans cannot complete the job rent a commercial Dehumidifier and close the windows (remember to run the dehumidifier hose out the window or door-don't kink the hose) the dehumidifier will pull all the moisture out of your home, if you leave a window open it will take millions of years trying to remove all the moisture from the planet.
If you follow these simple instructions your floors will survive this disaster and should outlive you and your tank.
Good times again!
