Is there any tile adhesives (wall or floor) that are cheaper than BAL and just as good i see Mapei mentioned a lot and Granspec i suppose im a little worried about trying different products other than Bal i really like working with Bal stuff but thats all im using and it aint cheap.
The reason im asking is i went to measure a job and it is 21.5m2 which would require 5 20kg bags im thinking of using BAL single part flex as it is a concrete floor in total with my 25% discount its gonna cost 111.63 inc vat just for adh' and the guy that has quoted before me has told that it will be £55 for adhesive and he has quoted for 39m2

do you think he has some left over or is he using somthing like wickes or b&q sh*t he has been tiling for years and i think i might lose the job because of this.
Any advice on cheaper places to buy from or just cheaper products (good ones) would be very helpful.
or am i best sticking (no pun intended) to Bal as it comes highley recomended.
