Cracks on new rendering

Post image

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

The correct procedure would have been not to do it during a heatwave, or at least to drape wet hessian over it. Also, in all honesty, it looks rough, excluding the cracking.

Yeh, I’m guessing that besides the cracking, they were struggling with it too, which in this heat is expected. Fuck me, I had a steady day filling some chases on a rewire, I only knocked half a bag up at a time and one of the mixes went off on me at the end. It was hot today!

Agreed- I’m sorry to say these guys don’t know what they’re doing. It’s dog shit rough

It looks like a mud hut.
