damp patch on cieling


Postby jollygilly » Mon May 28, 2007 6:48 pm

HELp. we had a burst pipe in bathroom over a year ago. damp came through the lounge cieling. We repainted this year and now the pait has started to flake off. At first it was about the size of a saucer but now it's got quitee big - about one foot in diametre and spreading. Can anyone tell me why this is happening and how can I stop it

Thank you :?

Flaking paint is usually a sign of poor adhesion to the surface which can be a result of painting while the surface is still damp or the surface being greasy through natural dirt in the air. Clean the area off, removing all loose material, rub down with sugar soap (see our project re preparing timber for painting) leave to dry and then apply a coat of stain sealer. See our project re blocking water stains for this. Then paint. Double check that the leak is fixed first though.
