Is it normal for the joints of a recently installed Pergo Floor to appear swollen?
On Pergo glued floors, you may notice swelling along the joints of your floor during the first 6 to 8 weeks after installation. THIS IS NORMAL. In fact, it is a good sign that an adequate amount of Pergo Glue has been used. It is caused by the absorption of glue in the core material and will disappear as the glue fully cures.
