Adhesive for bathroom walls

[penno]

What should i really go for when doing a bathroom wall with larger tiles?
BAL CTF or SPF?
Never really totally sure which i should really use.

How big do you consider a larger tile ?


CTF3 is a polymer modified cement based adhesive for fixing ceramic wall and floor tiles, ceramic mosaics, quarry tiles, natural stone, terrazzo and brick slips to any standard substrat\backing, ie, concrete/brick/block walling, cement:sand rendering, gypsum plaster, plasterboard, fibre cement sheets, cement:sand screeds, ceramic/quarry tile/terrazzo/hard natural stone, vinyl tiles/sheet, mastic asphalt.

Where as a single part flexi is designed for fixing tiles more along the lines of fully vitirfied and porcelain tiles to low porosity backgrounds/bases.
Suitable for use on concrete/brick/block walling, cement:sand rendering, and also, plaster, plasterboard, cement sheets, tile backer boards, concrete bases, cement:sand screeds, plywood overlay, ceramic/quarry tile/terrazzo/hard natural stone, vinyl tiles/sheet bases, mastic asphalt.

In my view for anything other than fully vitirfied and porcelain tiles on a standard porosity background I would use CTF3, but if I was fixing porcelain I'd go for SPF.

Cheers Fekin, meaning tiles that are say over 31 x 45 upwards.

If it's not porcelain and on plaster or just boarding then a cement based powder "CTF3"
