Which adhesive

[golfer1047]

Should have asked this before but ...........
I am tiling concrete floor with 450 mm tiles, and I initially bought some Mapei C2 adhesive, however on further search I can buy some Mapie C1 adhesive for half the price of the C2.

Am I OK using the cheaper adhesive?

i would use the C2 ,if it was me

C2 has twice the tensile strength as C1. Hence the price. C2 I'd go with too. Never scrimp a bit with adhesive, always get the best you can afford for the job.

You'll need a modified (C2) adhesive if you're fixing porcelain tiles.
