Mist Coat - Possibly gone wrong

chelt_Robin

I had a new bathroom fitted with all the walls and ceilings being re plastered. I am painting it myself to save on cost,

I purchased some cheap white paint and watered it doen to create a mist coat. When I started to apply it was dripping everywhere down my nice new tiles etc when doing the ceiling and onto the bath etc. I paniced and added more paint to about single to double cream consitancey, definitly thinner than normal. It went on better, but I am now worried it was too thick what can I do? 

Also how long should a mist coat like that take to dry.

Don't worry - it's a loose figure for diluting.

I doubt you can have it too thin - it'll just have less coverage. Too thick does run the risk of it not binding to the plaster as well as it could, but it's usually fine too.

How long to take to dry? Depends on how warm and ventilated the room is - with ventilation being the key. So, crack open the windows in there, and shut the door... Should be dry in a few hours, certainly overnight.

I'd seriously consider using 'bathroom' paint for the subsequent coats.

Yes, I think it could have been a too tick mist coast. It was too watery to start with it was dripping like rain when I painted the ceiling with it so added more paint back think almost too thick. Yes, I will be using bathroom paint

What's the difference between bathroom paint and matt or silk emulsion please ?

Guessing it has some kind of polyurethane content that handles a moist air ??

That's, er, a very good question. I understand just more resilient to being dampened and wetted. Possibly anti-mould too. 
And without needing to have a 'silk' finish.

Years ago, one of my friend's sons did some work experience at ICI in the summer. He spent the whole time working in the development of Dulux paints, and was surprised how much effort went in to new types of paint. Bathroom and kitchen paints were constantly being worked on. He also said that there was quite a difference between paints for trade centres and B&Q. 
A mate of mine who's a really good pro painter uses Dulux for kitchens and bathrooms. He did my daughter's house a few years ago, and it's still mould free.

Normal matt paint will absorb water, and stain more easily. Silk emulsion is more durable, but most people prefer a matt finish ( especially on the ceiling as a glossier paint highlights any small imperfections).
So with bathroom paint you get a compromise of a mid sheen finish, that is very durable/water resistant.
However it costs a bit more.
I found that Homebase do a 'Tough and Durable' matt paint . It is not promoted specifically as bathroom paint, but is claimed to be hard wearing, washable and stain resistant. So as I wanted a matt finish when I painted a bathroom, I used this and seemed OK.

In our previous house we just used ordinary white emulsion on the ceiling in the shower room, and it definitely wasn't the right sort of paint. After a couple of years it seemed like the steam was getting into the paint surface, and you'd see drips hanging off the ceiling when it was a bit steamy in there.

When painting our newly plastered bathroom ceilings in our new (to us) house we went with the proper bathroom paint on the ceiling so hopefully won't get a recurrance. We have used an ordinary silk paint in the main bathroom on the walls, but there's no shower in there and the bath is only used very occasionally, with the fan running, so we decided to risk it, given we couldn't find a bathroom paint we liked the colour of, and didn't want the expense of made to order. The shower rooms have bathroom paint on the walls.

Did you use a mist coat first in your newly plastered bathroom?
