No, unfortunately, the flooring is not defective.
We live on a farm, and with activities outside the house taking most of our time, our dogs have free run to enter and leave the house whenever they wish through a small pet door.
Unfortunately this means that during rainy days, as well as spring melting, the dogs can track water into the house when we are not quickly available to clean it up. So the water sometimes sits for a while before we return to the house and discover it.
And water seeping between the boards has a tendency to lift the edges of the top layers of the laminate.
That's why I have considered coating the entire floor with some sort of waterproof coating. The only concern I have is would the coating seep between the boards and seperate the laminate layers. And that is the reason I am wondering about an epoxy based coating with a hardener to create a layer of protection above the flooring, without penetrating between the boards and lifting the edges of the laminate.
And I was hoping that someone here may have tried this and could offer some advice.
(Aside from tearing up the entire floor and putting down something else)
