How to install Acoustalay 300+26th August 2012
Ensure floor is clean and flat (a flat sub-floor means deviations of less than 2mm over 2.5m). Unroll at 90º to direction of the floor, covering area to be laid. To assist laying, apply double-sided tape to the perimeter of the sub-floor.
If laid on a concrete sub-floor so the Acoustalay is to be used as a vapour barrier, the first row should be laid with a minimum of 20mm up the walls. Butt the edges of the next row tightly to the first, ensuring that they do not overlap. Carefully tape the joints using a waterproof tape. All rows, including the last, should be laid with a minimum of 20mm up the wall. This will be concealed behind the new or refitted skirting once the floor is laid. If original skirting is not removed then lay the Acoustalay 20mm up the skirting and conceal with appropriate scotia/trim.
Lay the flooring on top of the Acoustalay, referring to the manufacturer's instructions.
