Using Bathroom Paint but it Keeps Brushing off?

[stevem73]

We've been trying to decorate a bathroom using Dulux bathroom paint. Now we have found that as you paint (both with a roller and a brush) if you go over a bit that you have just painted it removes the paint off the wall. We have found that one roller with a thick pile didn't do this (but there are a lot of fiddly bits) and I am confident that the walls have been prepared properly but what would you suggest is the best way to do or does any one have any tips.

It sounds like the paint is drying to quick, open as many windows as you can to make it cooler in the bathroom as your painting, you could thin down the first coat a little with clean cold water.
