I recently noticed some white crusty stuff on all the edges of the LVP in my master bath, water closet, wife's closet and a step in to our bedroom. I work away so wasn't able to deal with it. It almost seems worse this weekend when I am home and it has me worried. What could cause it? It sure seems like it could be water up under the LVP working its way up. My wife also recently has a neoprene bath mat in the bathroom and water seemed to stay under it and no where else which didn't make sense. Is this a sign of water being under the LVP? I'm not sure what other signs to look for. There doesn't seem to be much else like soft drywall or bad looking baseboards. I will try and take up a piece or two of the floor to see if I see water this weekend, but I'm only home on a whirlwind trip. I am pretty worried though.
Appreciate any input.
