It depends on the circumstances, I think. We were told to leave it for a year, but this was after a total restoration which involved a completely new roof. Efflorescence is still an issue 14 months on. The interior finishing plaster (tonachino?) was applied to a rough lime cement render which covered stone walls which had been exposed to the elements when the roof was off- I think the rubble infill in the walls became saturated with rain water. We were also told that the tonachino (also lime based) did not need to be painted because it was already impregnated with colour. We will paint it eventually, though, because it has become discoloured by the egress of moisture from the walls.

It depends on what your plaster is made of, and what sort of pigment or paint you are going to use. The renaissance fresco painters didn't have the option of letting the plaster dry!

Would the inner wals be really soaked ? How long was the roof off? You need to give it at least 1 summer to dry out.Maybe 2 years?I would be slightly worried water was trapped inside the walls but you mention lime plaster which will let the water through to the outside.Cement traps water in leads to stone decay and wood too.
I've found the period property website (uk) very helpful as I don't know anyone in Italy using traditional methods/lime plaster etc and most of our builder friends have never seen it used!
I like the brand biocalce which has a huge range of lime based plasters We used a premixed mortar to repoint and it was lovely stuff with small quartz chips in.At 18 euros a bag its pricey but I found sand could be added at a 1:3 ratio.Now I by bags of lime hyradte at 2 euros and make up containers of lime putty which I mature for 3 -12 months before mixing with sand and this makes a lovely mortar for pennies.

You can get a liquid which you dilute 1plus5 to 10 which goes cloudy white and dries transparent (acrylic based I think) and you use before the paint proper, available at all self-respecting ferramente, worked for us.

This agony uncle guy is fantastic!!! He seems to have an answer to most questions so if you've got time you can browse thro.Its always tempting to try to get things finisfhed asap but sometimes its best to do things more slowly and carefully especailly if you don't want damp problems to continue into next year.
Good luck

Thanks everyone. It mainly appears that it depends on what plastering is being done and how it may take to dry out. However, there are some methods of speeding up the process!
If my geometra gives us any helpful information I shall let you all know.

This could be the same as a 3:1 water:PVA mix. Paint it on new plaster, wait until tacky and then paint on the undercoat. Works very well
This may help
