Installation of Tuplex
Always follow the flooring manufacturer’s instructions with respect to preparing and levelling the sub-floor prior to installing the underlay and flooring.
Make sure the sub-floor is clean and dry.
Lay out Tuplex underlay so that the seams touch and overlap, do not tape. Cover the entire floor area and run the underlay flat on the sub-floor so that there will be a small gap between the wall and underlay, approximately 5mm or so.
This will let the underlay to breath the possible moisture out from the sub-floor. This way your valuable floor will last long, but always the Tuplex underlay lasts even longer.
