Step 1 These floors are best laid by first removing skirting boards. This allows for expansion and contraction around perimeter of floor, which will then be hidden by skirtings. Rather than cutting around architraves, using electric multi tool, cut a sliver off bottom of architraves so underlay and flooring can slip underneath. Sweep and vacuum floor.
Step 2 Roll out underlay and cut slightly long. Make sure foil edge is clear of underlay, then roll out next piece parallel, with its edge butting foam and foil underneath. Stick together using provided adhesive strip.
Step 3 Trim underlay to walls of room. It doesn’t need to be super accurate, since underlay will be covered by flooring.
Step 4 With tongue facing out, put first flooring piece on underlay along 1 wall. Don’t worry too much about aligning at this point – the floor can be pushed into place once the first few boards are connected. Bring in a second board and clip to 1 end. Keep adding boards for first row.
Step 5 Before starting next row, using power saw along a square, cut 1 board at the end, stagger joints, then push in place. The profile is designed to go in at a slight angle and, when pushed down, they will click together.
Step 6 With each board clicked to previous row, push along to click to end of adjacent board. Take an offcut of board that fits profile of board end and, using rubber mallet, tap offcut against board end to achieve a tight joint. Once you have a few rows down, push in place so you have an approximate 10mm gap around perimeter of floor.
Step 7 Chances are you will need to rip the final boards to width. Do this using a fence attached to your saw, or by drawing a straight line and cutting by eye (the cut will be covered by a skirting board).
Step 8 Replace skirting and nail to bottom plate of wall framing. In full brick houses, you will need to plug walls in order to nail skirting, or simply glue skirting in place with construction adhesive.
Step 9 Where there is a step up, as here, cut a piece of flooring to suit height and, using construction adhesive, glue in place. You can finish top edge where end grain is visible with an anodised aluminium cover strip. Hold in place with tape until glue dries.
