What are the general rules of thumb for painting the exterior of a house? The surface is currently unpainted dry dash rendering. Do I need a sealing compound on it first? Also how many coats is the norm? What square metreage / ltr can I expect to get from masonry paint? Brush or roller? I realise each situation is probably different but just some general thoughts would be appreciated. Thanks. Cheers
Roland I would aply 2 coats by roller with the first thinned 10% water in order to make it easyer to apply the second coat should be full strength and will be Quicker. I would estimate that coverage would be 5/6 meters square a coverage (just my opinion) I normally use stabilizing solution if the surface is powdery and or leaves powdery deposits on the hand if rubbed over. Also use quality paint Dulux trade or leyland. Regards Paul
