Can a flexible additive be used in any cementitious tile adhesive?
The supplier of the adhesive I bought told me that the adhesive is for "rigid" substrates only not for "flexible" substrates like plasterboard, which is where I am installing the tiles.
I have heard that wooden floors are regarded as flexible but have not heard this about plasterboard on studs.
The plasterboard is in a bathroom on stud walls. Yes, if I push the plasterboard with my hand, where there is no stud, it moves a little. It's 12.5mm thick. I have a wall mounted cabinet with basin but it will be screwed directly into the stud members with local reinforcement for it.
The tiles are heavy, though: ceramic 11mm thick 300x600mm.
Do I need to worry?
