topps toppfix flexi / primer

what primer would you recomend with this, ive been using bal APD but the
only job i had in december rang back to say some grout was cracking

went round and sure enough some tiles were loose

the ply was already down even before the kitchen went in and it was well screwed down

looking around the forum most people say bal bond SBR would be better is this right?

What adhesive did you use and when you say kitchen floor what is under the ply..?

this is the adhesive i used, under the ply was chipboard flooring

So was this a floating floor or on joists..?

I use palace tilers primer which is really great, its an sbr i know that palace make topps own brand so if it the same its good stuff

what thickness was the ply?

not a floating floor the boards are on joists

to tell the truth i never thought of the ply thickness, as it was already down and the only place i can check is at the door, will have a look when i go back
