bold statement there ,been about for a long timemono is shite its just a fast way for builders to turn over houses no painting scaf out of the way fast
what about when a building has had a pre rend base coat first and yet still seems soft!
it is down to the set or curing gone wrong.
if you see a mono job done in winter it never sets as strong as it should be, if the temps have been freezing overnight some jobs will forever come away and you will constantly see dust and bits falling away.
the cold breaks the set
And in good weather?
if you take measures to control the suction in hot weather then there should be no issues. the bags must be in good date. anything at the end of shelf life usually always misbehaves
Have you ever had the sun kill your Mono or should a good Renderer never get in that situation out of interest ?
