Painting after plastering

Code117

After a bad disaster with tiles attached with cement mortor, I have just had my bathroom fully plastered. Now I'm not sure of the best plan of action as I have never painted a bathroom before. I have painted over wallpaper, but that is the extent of my decorating.

I have some dulux bathroom+ paint in the colour I want. I have a man coming in a couple of weeks to tile the bath\shower area.

Now believe I made a mistake of listening to my plasterer when he said I could directly paint right away, so now I have painted my ceiling. As I said, bit clueless.

Now, when sanding the wall, as it is a bit coarse and not smooth, I saw I should have used a primer. People are talking about mist coats and watering of my paint, but I'd rather be sure and get the primer, especially when I'm not even sure what it all means.

Problem is, what about the none primered ceiling? Also, can someone do a quick step by step of what to do right up to the point my roller hits the wall.

Be honest, and while I would like to get some experience, if it is really needed then tell me if I should go with a professional.

Hope someone can help this improperly raised man who knows less about handyman things than most should.

All you need is a watered down mist coat of contract matt emulsion to prime the plaster and stop it sucking up too much moisture from your top coat, which will leave it sitting on top of the plaster and it will just peel off. Maybe a second coat of less diluted emulsion, then two top coats in your chosen paint.

I have also used Screwfix's bare plaster paint with some success but would recommend diluting the first coat a bit anyway just to stop it drying so quickly.

Please ignore anyone who suggests putting PVA on your new walls and ceiling.

When we had the house plastered we just did a first coat of watered down white paint - probably about 50/50 or 60/40 and then we could paint straight over this.

I would agree with post 2. Get some new plaster paint from Screwfix, it's not expensive. Water down the first coat with 30% water then second coat as normal. Finish with your preferred top coat. Done 5 rooms this way without any problem. Do not scrimp on the quality paint especially in the bathroom.
