painting exterior wall

[noddy]

hi there,
I am about to paint an exterior wall yet again.
I have no problems with 2 walls which are block but another dividing wall blisters and blows? for want of a better word. the one causing the problem is constructed in concrete sheets approx 6 foot x2 and placed between concrete posts. Do I need to use a stabilising solution or can I do anything else to stop this from happening

Yeah, stop using paint and try limewash. People just don't understand how good these "old " materials were (and still are).

Hi oilman,
thanks for replying. The only thing is I,ve just bought 3 large tins of paint and have repainted one wall and it looks lovely. I,m very pleased and so is my worse half. I,ll just have to scrape it off this problem wall when it happens [/url][/list][/list][/quote]
