I am about to install laminted flooring in our den and was reading up on the subject. There are conflicting issues that I would like clarified. Would appreciated comments from all those who have installed laminate floor. ON 1 brochure it says that you apply a thin bead of glue/sealant between each joint and another said that you apply a thin bead of sealant on the first row of flooring so that it would stay in place. I went by Lowes and ask one of the floor sales person about it and he said that you can do both. If I were to do both then my cost will increase but is it absolutely necessary to bead on every joint or the first row for that matter? Please help.
