Painting an outside rendered wall

[andemz]

Hope someone can help me. Can you advise what paint and how best to apply it to a large wall that has been rendered using red sand, cement and lime. The finish is good, but now i need advice on what paint and whether i need to put a base pva on it first.

Any suggestions are welcome

A simple masonry paint is fine. They usually last 15 years.

Thanks for the quick reply. So, no bonding agent or anything like that, just simply put the masonry paint on neat straight onto the wall.

Just follow the instructions on the back of the can. If the surface is really dusty then you'll need to seal it first.

Make sure its a good quality exterior brand (Dulux Weathershield/Crown Stronghold etc) - not something like B&Q's /Wickes/ Homebases own. ...Slightly thin the first coat -say 25-30% water- to new render if absorbant
