Hi. Decided to buy a new Ryobi One jigsaw (cheap-as-chips at $79) which works a treat (the old corded thing I have is a shocker). Also realized, most if not all cut ends should be facing the walls, so will be covered by the beading I intend. My problem now is I can't seem to get the planks to join properly. I'm using a rubber hammer and giving them a good whack over the join (not to either side of the join). Though I was told I could use up to 2mm underlay without voiding the planks' warranty, I'm beginning to think that may have been wrong. These planks come with underlay attached. While I would value the second layer of 2mm underlay for improved sound-proofing, it may be that with both the attached underlay and the additional 2mm, there is too much give when I hammer to join the planks properly. Any thoughts here much welcome. Best.
