How do I trowel a "flat bed" for floor tiles?

[zappastix]

Hi

I was looking at some Wickes floor tiles and it states they need to be bedded
in on a flat bed.

I need to raise my floor up a bit - so a 10mm deep bed of powdered adhesive mix
would be handy, but how do you apply a deep bed?

Normally you'd use a notched trowel to get the right depth, but I cannot see how you
can trowel in consistently at the right depth (or do you have to keep adjusting with level)?

Any help appreciated.

Thanks. Stephen

A “flat bed” adhesive base is achieved by using the correct solid bed notched trowel not by physically troweling the adhesive base flat.

Doing it like that will most likely end in disaster & it will be almost impossible to keep the tile surface flat & looking good. Adhesive bed thickness is usually around 3-6mm, it can be built up locally but even the best cement powder adhesives should only be used up to 12mm & only locally as stated. You first need to raise the floor to the desired level using a self levelling screed or a proprietary quickset render; do not use a conventional sand/cement render to screed, it will fail at that thickness.
