Water Stain in newly plastered ceiling - Best way to seal properly.

Anonymous user 23/02/2024 - 3.30 PM

We had our kitchen ceiling fixed and replastered due to a previous leak in the bathroom which had since been fixed. Around the same time, we got our bathroom refurbished but when the plumber installed the new bath the overflow pipe wasn't connected properly so the first time we had a shower the water leaked through the ceiling. This has now been fixed but there is now a large water stain on the ceiling but no cracks. I have left it for over a month now to make sure it has dried out. I will be painting this soon but should I apply a stain blocker before applying the mist coat or after? Any recommendations in which stain blocker to use and tips for using a mist coat on a ceiling would be greatly appreciated too! I’ve only used a mist coat on walls so far and have a feeling it could be quite messy given the watered down paint I will be using. Thanks, M Update: Thanks for the reply ID Decorators Limited, i'll give that a go, hopefully all works out.
