The vinyl flooring in my kitchen has yellow stains around the perimeter and near the floor vents. I suspect the stains are from glue used to install it. I'll be installing new laminate flooring soon. How do I make sure this doesn't happen again?
Like you guessed, those stains are most likely a chemical reaction to the adhesive underneath. If you're replacing that vinyl with laminate you have nothing to worry about: Not only is that condition not known to occur on laminate floors, but laminate floats - it's not attached using glue. You do want to make sure you remove the old adhesive before laying the new laminate, though. Good luck!
