nzviking: Surfactant leeching. The nemisis of bathroom repaints.
 

At the risk of thread cr@ping (but will hopefully show others what not to do!), I wonder if this is the problem we have; we had a small bathroom built about two years ago as part of an external HT, and did the painting ourselves. I can't remember the type of paint we used, but clearly we did something wrong!

Whenever it gets steamed up from the shower colour runs from the paint, like the pigment is coming out. I had wondered if it was something wrong with the paint itself (like too much pigment in the wrong base), but now I wonder if this is this the "surfactant leeching" you mentioned?

If so, what is the easiest way of dealing with this? I know we used a pigmented sealent on the gib (aqualine), but I assume it's something to do with the top coat paint we used. Can we just give it a light sand and put on a coat or two of the more appropriate paint (whichever that may be)? I really don't want to have to take it all the way back!

Thanks for any advice...
