hi all

Just wanted to hear your thoughts on the best bal adhesive to use on my slate floor tiles, its straight onto a self levelled floor . looks like the main ones are;
PTB flexible thick bed
rapidset flexible
or rapidset .
they all have the porcelbond logo could i get away with the rapidset ??because already have a few bags of rapidset in my stores!
thanks

Hi..

If the slate is calibrated well then rapidset will be fine if solid bedded.. but if natural split slate then PTB might be better, just depends if you have used a PTB before..

definately flexible for me

Flex rapid would be my first choice but rapid will do the job. I've just got a thing about using flexible for everything! :lol:

dave ive never used the ptb before is it tricky? everybody sees to like flex bri !

What is the substrate that the self level is over?
