use a mineral render on an sm700 or maitie as said
 
was wondering if weber rend aid 2 be ok to use? but to be honest I may turn this job down as I don think architect knows what he doing! talked to few lads on the job and they agree!he supposed to be project managing the job and hasn"t shown his face much!he seems to pass the buck
 
what would you do in this situation ? I really busy so don't need hassle!but I love the challenge of new broken boundries lol :-0
 
Sand and cement wont stick or flex enough to last over insulation. Simple reason why you use a system with a dedicated adhesive base.

To use sand n cement u would need to riblath it and it will still.crack

this is what I thought!i need to tell the customer that the architect has dropped a bollock in recommending a sand cement finish with this system!not sure what to recommend for this time of year!any ideas?i don't spray its all by hand!:RpS_thumbsup:
 
You nasty ******* Andrew!.

Parinter finishes nice but I find sm almost turns to like a lime putty and it's very hard to get the grain looking even.

You know I'm right..... I'm always right, ask my wife.
