Hi,
I'm having to relay my patio (didn't get the fall correct - schoolboy error)
I'm happy now with how to achieve a fall - but the slabs laid about a week ago came up very easily, just a spade under them and they popped up.
I guess what I'm asking is:
A) how to prep the base for good adhesion - it's a solid poured concrete base that is level and smooth
B) how to prep the underside of the slabs for good adhesion - they are 22mm calibrated sandstone
C) what mix of mortar/tile adhesive you'd lay these on
Thanks in advance
