The key with installing floating floors is to follow they manufacturer’s instructions.
I can’t stress enough, expansion, expansion, and expansion.
When starting, I always start on the left and generally pick the longest side of the room, but that will also depend on other connecting rooms and the way you want the direction of the grain.
Remove your old carpet if your have it and under lay. Knock off the smooth edge from around the walls. If you are going to remove skirts, now is the time.
Check the floor for level and level if needed.
I use a piece of the new underlay and a piece of the new board to use as a guide to undercut any door jamb and architraves with the multi tool.
Give the floor a good clean and vacuum. Start with rolling out some under lay, be sure to install the right way up. Lay your first board and continue across room. Most manufacturers recommend a min 10mm gap between edges of boards and walls for expansion. We use 10mm window packers. Failing to do this can cause the boards to pop later, and also void any warranties. When you get to the right hand side of the room you will need to cut a board, so this allowing 10mm to wall. The off cut becomes the first board on the left of the second row. Continue this all the way across the room.
I like to roll they under lay out as I go. Keep going till you finish the room.
To finish up, either put Scotia around the walls if you have left skirting on or replace the skirting.
Doorways. If the flooring is to continue into the next room, I still prefer to leave an expansion joint at the doorway that will have a cover strip over it. Do all doorways the same and then it won’t look out of place!
1) Use as many expansion joints as you can.
2) Make sure your substrate is level and within tolerances.
3) Take your time with detailed cuts.
4) If you are using a hammer or mallet to tap boards together, be sure to use an off cut and tap on that, not your board you are laying.
5) If you are putting skirting boards back over the floor, remember that you need 10mm gap on floor to wall and most skirtings are 11mm. Doesn’t leave much room for error. You could possibly purchase new 18mm skirting but that opens another kettle of fish. One for another day.
Good Luck and take your time. Or get the pros to do it.
