I need to repaint an area of exterior wall under some ground floor windows which is badly flaking - probably no more than a square yard
- and have found a small can of dulux 'feature wall'. I quaked at the prospect of buying the minimum quantity of masonry paint which would of course have been more durable but horrendously expensive for the area needed.
There is the added concern that the dulux is intended for interior walls but my question is: Can I reasonably expect this paint to last for a year or so by which time a more comprehensive decoration scheme is likely to be undertaken?
The guy at B&Q said he thought the paint would run in the event of rain. Is that really likely?
