Parents have been advised to wait 7 days before painting re-rendered wall ?

My parents have just had someone in, who has re-rendered part of one of their external bungalow walls. Taken him 2 days to do the re-rendering; one layer each day.

He has advised my parents to wait at least 7 days before painting the wall and to use a 50:50 water & paint mix for the 1st paint coat.

Is this correct and, if so, why ?

You need paint watered down so it soaks and seals and allows any further coats to then adhere. Not sure on the ratio of the mix

This time of year a week is just about long enough to dry out, thin about 20% as 50/50 will splash every where,but wont do any harm if you do use 50/50 for the 1 st coat.

you should be able to see if the render has dried out , obviously don't paint if it still has damp patches
thin first coat 50/50 and then add a bit of water to 2nd coat , 80/20 and then add a splash of water to any further coats - 90/10

System

depends on the type of rendering, seven days really is a minimum, people supplying exterior paint should be able to tell you which products are suitable, but i'd be surprised if any render has fully dried/set in that time frame

one week is the absolute minimum. 2 weeks would be a lot better.
even is this dry warm period.

Thanks for the advice. I will wait a couple of weeks as I'm going on holiday next week and will then paint it upon my return as advised above.

Really impressed with the young guys that did this. One was a labourer (he admitted that himself) and the other the qualified plasterer. Just started out in business, took cash in hand, got a really good deal (cheaper than anyone else) and have done a really good job.

Got a busniess card and will be providing feedback to describe the work just to ensure that I am covered in case of any probs; although I am not envisaging anything. Very impressed with them ! It makes a refreshing change to see genuine workmen that go the extra mile to deliver a service.

Plasterers are always cheap. I had my house replastered for less than half the cost of a decorator putting up lining paper.
