    Hi guys,

    Just wondering if I should just lay the boards and screw them, I've heard you have to glue them with something. What glue would you recommend and is there anything that I have missed?

    Which screws are the best, I hate making pilot holes as it's going to be long winded.

    Cheers guys

    Are these flooring panels you’re laying? If so, yes - the joints need to be glued. Fix the panels down in a staggered ‘brick’ pattern. Any decent wood glue will do, such as this;

    It also comes in a bigger 1-litre bottle if you have a large area to do. Run a good dose of glue along the top and bottom of each tongue, and don’t forget the ends.

    For no-pilot screwing, a good quality rifled-shank driving screw is best. For 18mm panels into joists, a 40mm screw is ample. Make absolutely sure that none of the joists have pipes or cables notched into the surface - avoid these obviously, and make sure your joints are nice and tight before screwing down.

    Decent screws from our hosts are these;

    Screw every 500mm or so.

    Hi, thank you for replying. They are 2400 by 600 boards.

    Mark on the boards where any services are as you lay them. This will help anyone in future who may need to access them for whatever reason.

    If it’s a suspended ground floor and isn’t insulated i’d do that first as well.

    I would use Reisser Cutter 4x40 screws and they will countersink themselves.

    Screw on every joist - around 50mm from te edge and one in the centre.

    I used d4 glue on the tongue and the groove, on the ends too, I also put a bead of glue on the joists as well, I used spax chipboard screws, they were expensive but really were brilliant screws.
