A customer I have been working for wants a new retaining wall tanked before it is fitted with 6mm 1200x1200 porcelain tiles. The builder didn't sort out any water penetration issues when it was built unfortunately. Have any of you raked the joints back 10 to 15mm prior to a sbr slurry coat ?
 
Lol , it sounds a bit over the top but I think the customer is going to want it as he's found a product on the internet and that's what they recommend :(
I would argue that your the plasterer and you know what your doing
 
I think I'll advise him to get someone else to rake it out as I can't be arsed, job done :D
