I have just had the outside of my new kitchen extension sand/cement

What is the process for painting new render.

Put brush in paint and move brush up and down on wall?

i.e. nothing special., HOWEVER if the wall is subject to driving
rain and heavy frost, consider using a waterproofer first. I got
SOME spalling on a new render wall where the rain was 'bouncing' off
some lead topped window frames, soaking into the render and freezing
- this on a dank north west facing wall.

Thanks


S/SW facing is the most vulnerable in the long term. A solvent based
pliolite paint from e.g. Johnstones would be a better bet than
ordinary masonry paint. Expensive, but well worth it IME

Only from UV degradation, but IME that is not an issue with modern
paints.


Looking at the houses round here, all S/SW facing windows are shot to
pieces, or have been replaced. Opposite side of the road, mostly
original woodwork.


Windows and wood, yes. Render, no.
