Is is necessary to grind the surface of UltraTech® to weld seams?
A. Unlike polyethylene, which must be abraded on the surface prior to welding. UltraTech® only needs to be wiped clean of any dust or moisture prior to welding. Since grinding is not required, you are assured of having full thickness of the liner in all areas, and need not be concerned about the loss of thickness along each seam.
