Im just about to start laying some oak T&G flooring in the living room. Now
I can obviously hide the expansion gap under the skirting, but when it comes
to the granite hearth, Im stuck.. Now i dont want to have any beading as it
will spoil the look and obviously if i butt it up to the hearth im gonna
have problems later on, whats the minimm SAFE gap i can use and ideally
would it be possible to use some type of silicone product so it would blend
in with the floor but still give me the safety gap
The best and most difficult thing to do is to get an angle grinder with a
stone cutting disc and cut a line along the hearth exactly at the point
where the top of the new floor will be. Cut out all below it. You will then
be able to tuck the floor 'under' the hearth. You've got to cut pretty
Use beading. Just lay it flush with the surface of the floor.
You'll need the ability to machine rebates. Make a beading strip
that's 3/4" thick, like your floor, and has a wide half-thickness
rebate underneath it. Machine a coresponding rebate on the upper edge
of the floor. Chamfer the edges to look a bit neater, then lay them
How are you laying it?
If it's fully floating then I can see the need to leave an expansion gap,
but surely not if each board is fixed down?
