Painting Roughcast?

[ds1990]

Neighbour of mine is wanting me to paint the exterior of her house. It's wet dash which is already painted but it's been patched up everywhere and wants it painted over again. Can anyone recommend the best type of paint to do this?

Johnstone's Stormshield will do you ds, if there is water staining then touch up with anything oil based, pliolite masonry will dry quickly, then full coat stormshield or any trade masonry paint

Good man cheers! So just 2 coats of storm shield won't need a primer coat or anything like that?

No primer needed. If there's a lot of them, touch up the patches 1st with the masonry paint. Check the existing painted area for big blistered areas which look ok at 1st glance. Heavy coat for 1st coat which will make the second coat just a skite. Check for any staining burning through after 1st coat & seal up with any oil based paint then 2nd coat. Bucket trough style tray, not the flat diy things, big roller sleeve which you may have to change after 1st coating. Hope this helps
