I have a remnant of this Super Duty flooring. I used the other part of it for my kitchen. It is weldable or use seam sealant if needed. It is 4'5" long and 6'6" wide, 2mm or 5/64" thick. I have some other smaller pieces also. I will give you a gallon of floor adhesive with the flooring. I have sold the groover, but I still have the welding gun. It is not for everybody to weld flooring
