Hi, after running out of money I had to lay my patio myself. My wife decided on 20mm slate paving and after extensive research on how best to lay it I soldiered on. It has now been down for 48 hours, I walked on the edge of it today and the larger stones seem ok, the smaller ones (a 200 x 200 and a 400 x 200) both popped when I walked on them
I used a 6:1 semi dry mix (prob more towards the dry end of the scale as was worried about staining them) and used the SBR bonding slurry. When I look in between the tiles the mortar is grey and crumbly.
Can anyone please point me in the right direction / offer some advice? If 2 have popped are they all likely to go? Will I need to lift and re-bed every tile? Many thanks for your help
should have been wet mortar, semi-dry wont bond even using SBR on the back, the stuff you used was way to dry to bond and cure.... might have to lift them all and start again MSH
