Tiling . . .

[Jontie]

Fogey,
Don't try to do it with adhesive. Go to your builders merchant (usually cheaper than B&Q) and get some floor levelling compound. Mix it as instructions and pour it on, it'll find it's own level and then tile as normal on that! HTH

Thanks for all the advice guys

A couple of other points -

screw the floorboards to the joists and then screw the ply at 6 inch centres to the floorboards, it seems over the top I know but if you dont and the grout keeps cracking and coming out its too late to fix it !

And its important to use screws not nails !

And also its a good idea to use silicone round the edges not grout as grout is likely to crack when the floor moves

What are you tiling onto ?

OK, should have read all the posts first, as its on to a flexible substrate use two part (latex type) self levelling.

Does it really matter that the floor is not level, note I say level as it does need to be flat.

Self-levelling is no good if the floor slopes, it will try to run with the gradient.

That's kind of what it's supposed to do.....

How steep a slope are we talking here? Will there be a lake of self-levelling compound up against the skirting board or does 'sloping' mean 'not entirely level'?

It's not an excessive slope - the floor just slopes down slightly towards the door - have to go with it as it is as I dont want to create a step in the doorway (just means it'll be an uphill walk to the loo in the mornings )

What about concrete or stone floors. Can I use the self level stuff on that?

No, it's for filling in dips, nooks and crannies on an otherwise LEVEL floor.

'self levelling' can also been referred to as smoothing compound - depending on how thick you make it up.

Obviously if you have an appreciable gradient you have to be a bit vigilant while its going off and re-trowel as required

I once 'plastered' a metre or so of rough brickwork above a worktop with it prior to tiling, a case of making do with what you have to hand ! made it up very thick with sand, worked fine.

If you do use it make sure it is very well stirred, with a drill mixer is best, and then let it stand with the occasional slow stir with a stick to allow the air you have stirred in to rise, though not too important if you are tiling onto it

Definately - you can even use the cheapo one pack type !

If its going under vinyl remember to rub it over prior to laying the floor covering with a rubbing block (or a brick) to remove any trowel marks or snots
