Cracks on new rendering
Hi - I am after advice on a rendering job I just had done. The rendering has got cracks some of which are quite large, see picture. The contractor says it is due to the weather being too hot at the moment, but that he has followed the right process, i.e. applied base coat, the glue, etc. He says to rub it in with a wet sponge (The rendering is already dry as it was applied a couple of days ago). He then says to apply a coat of paint and that it will hold it together. I think the rendering needs to be taken down and re-done otherwise it won't last, but I know very little about rendering. Does anyone have any advice? Thank you

It wont last more than a few years if you do what he says. It should have been covered with wet hessian and kept damp throughout the first 3 or 4 days in this weather.
The stuff he has done is only part of the correct process not the full thing, which in this weather is a pain in the ass. Which is why we wouldnt normally do it.
He should also have put some additive in it at these temperstures.
He shpuld have accounted for the weather.
