- Roll out E-Coustifloor ensuring that the black membrane is face down.
- Where it butts the wall allow approx 75-100mm overlap at each edge and cut using a sharp knife or scissors.
- At this point push tightly together and tape along edge using suitable carpet tape.
- Where the floor surface is uneven, or the shape of the room causes “bagging” of the E-Coustifloor, it can be glued to the substrate using a general purpose contact adhesive in order to give a flat even surface to lay the floating floor, laminate or carpet over. Where the E-Coustifloor needs to be cut around irregular shaped rooms, corners or through openings use tape to ensure that any over sized cut is repaired.
- At the room corners notch the E-Coustifloor by accurately cutting out a square.

- Lay the flooring finish over the E-Coustifloor preferably at right angles, or alternatively if joints are running in the same direction stagger the joints. Glue the T&G joints where present or ensure that the click system is properly located. Whatever the jointing system ensure it is secure. In order to comply with Approved Document E when used with removable laminate flooring the E-Coustifloor must be adhered to the substrate.
- Mitre the E-Coustifloor by turning down each flap in turn and trimming off at a 45 degree angle.
- Turn the E-Coustifloor over the top of the floor board and fit skirting so as to trap the overlap underneath.
- Where the floor construction does not permit the end detail described above to be used, alternatively leave an 8-10mm gap between the edge of the laminate and the wall and fill with E-Cousti Fix and Seal then finish with an appropriate edging strip.
- Trim the excess with a sharp knife.
- Finish off by applying E-Cousti Fix and Seal to the joint. The E-Cousti brand sealer must be used.
- You have now created a floating floor which is decoupled from the base floor and surrounding walls reducing the transmission of sound through the structure, and by flanking and leakance helping you to meet the requirements of Approved Document E.
