Painting & Decorating Question

New plaster walls & ceiling

I have just had my ceiling and walls freshly plastered, as I had an artex ceiling and had electrical work that reuired the walls to be skimmed. It has been a week since the job was done and the plaster has turned a light pink which I assume means that it is now ready to paint. I have some left over paint from another room that was done by a builder - Leyland Trade Super Latex Matt Emulsion and Leyland Trade Contract Matt High Capacity Emulsion. I need to know:

1) Should I wipe my plastered walls with a damp cloth before painting
2) Should I dilute the paint before using, if so, by how much. The builder did not dilute when he did my previous room but I experienced problem when painting the room with the final coat of paint.
3) Do I need to sand the walls after the base coat or can I go ahead and paint the final colour.

use the trade contract matt thinned down first coat 50/50 with water, then a further two coats should do the job. Contract matt has almost no vinyl content which allows plaster to dry out through the paint. A common mistake made is when people put a vinyl matt or silk on plaster that looks dry but has still got moisture that needs to escape the vinyl creates a seal and the moisture makes the paint fail when trying to escape.

if its good plasterwork you should never have to sand or wipe down prior to painting ,dilute 50/50 emulsion/water and apply a mist coat which will sink in quickly and show up any blemishes that may need slight filling ,then apply a further 2-3 coats colour of your choice to cover
