Hi guys new hear would like to say hi to you all and introduce myself my names george from north wales.
Any way rendered a chimney scratch went on well no probs.. 4/1 mix...yesterday 5/1 topcoat float finished..any how the bloody sun and wind came out behind the clouds and burned all afternoon.. seemed to set ok after cheaking last night..then this morn i looked at the work and notied 3 dark patches..went up and there were 3 little hollows in the render..surface seemed hard enough., but while i inserted a finger and circular motion it i could go deeper and deeper into it...allthough it seems hard whats the cause of this, noticed a corner like this to and i could scratch away at it and it crumbled.. has the direct sun caused this?
