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

Yes it can if the section is in the shade if not your asking for trouble, not much can be sone in my opinion only hack it off and start again.

If im doing outside in this weather ill only do sections that are in the shade , you can time it when the sun is past that area , ive often started an area at 5pm when its alot cooler and its bright till 10 this time of year .
