"Yes, it's fine, but if the channels are wide deep, get some carlite bonding to fill first as if you use plaster it will get airline cracks in it you can get both from any DIY store BQ I would recommend"

"No. Two coats is always required for plaster works. This gives the walls a longer lasting guarantee."

"If it’s for patching electrical chases then it’s ok but you’ll have to bond out the areas first as you shouldn’t be applying plaster thicker than 3mm really. I’m not a fan of one coating anything and would always try to apply two coats anywhere I can just as a rule of thumb! Good luck!

"You need to bond the chases first then you can ever do a one coat of plaster and sand it or use filler and sand it"

"It should be fine for a small repair job just as long as the entire wall doesn't need doing."
