Refer to manufacturer’s installation instructions. Install cushion in the longest continuous lengths possible with consideration to traffic patterns and carpet seam placement. It is required that cushion seams be at a right angle (90º) to carpet seams or offset at least 6 inches (150 mm). Butt cushion seams net without compression, leaving no gaps. Do not tape or staple cushion seams for double glue down installations.
NOTE: Cushions should be specifically designed for double glue application and should not exceed 3/8 of an inch in thickness.
