    Hi Guys,

    Currently wanting to relay a new laminate flooring on the upstairs bedrooms, have stripped the old laminate flooring to the floorboards which I have fixed, some were creaking which I have now screwed back into the joint timber, however I would like surface to be flat and level which I have decided to lay plywood flooring on top.

    Questions is,

    1. Is plywood flooring the correct type of wood to line the bedroom flooring on top of the floorboards

    2. Should I water condition them and leave at room temperature for one day before laying them

    3. is 9mm thickness enough for the ply lining.

    4. To cut the ply should I use a circular or just a standard laser jigsaw ?.

    5. Should I undercut door frames from the bottom to adapt/tuck in floorboards underneath, what should I use to do this? Saw/ Hand tool (what handtool ?)

    If you guys have any other advice please do let me know.


    The goal is just to have a nice flat surface to lay laminate flooring on, bearing in mind an underlay will be laid under the laminate flooring. The floorboards are ok but just creak in areas and some are little higher.

    Thank you to all in advance for your replies.

    Kind regards

    9mm ply is fine, Jigsaw will take all day so use circular, leave them in the room to acclimatise is a reasonable idea, undercutting I wouldn't bother personally but if you do a multi tool is your best bet. Think about how you'd actually get them slotted under first.
