I have 20 or 22mm t&g wooden floor to fit ontop of old marble tiles but there is no t&g on each end.
Should i glue it down straight onto the tiles or put underlay down and leave it floating?

Thanks in advance

[welsh brickie]

underlay and leave it floating, for sure

[sam423]

Ok thanks

Will i need to leave a permanent expansion gap around the perimeter under the skirting board?

[sam423]

Also the ends are not t&g will they not lift if not glued down?

[welsh brickie]

yes a 10mm gap is required for expansion, a timber bead tacked to the skirting will keep the floor down

[sam423]

Will the skirting board not keep the boards down?

If i tack corner bead to the floor and the skirt will that not stop the floor from expanding and buckle the boards?

[welsh brickie]

if your laying the floor and then fixing the skirting on top of it, then no beading is required
