Painting sand and cement (internal)

How long after plastering should I wait before applying sealer and painting? Its inside a large garage and the plaster is sand & cement. Before painting do I use a sealer or primer? Thanks!

You need to apply a 'mist' coat first. Watered down emulsion or masonry paint (roughly 50/50 mix) should be fine as a 'primer', then paint as normal. Prepare for splatter, it is messy.
How long to wait depends on conditions, it should be fully dried out, no damp patches at all.
Personally I wouldn't go near it for 3 or 4 weeks, but I have seen painters paint it earlier.

Great thanks for that.

Now what about colour? one thought is green floor and beige walls, earthy tones.

Other option is this one, I found on a US website, its a long way from grey and white!
