One of the most difficult substrates to paint is bare block wall (breeze-block) its a nightmare.we have started using our own method, if your on on a commercial job where there is lots of block wall to paint you can use spray skim fillers or even ready mixed joint compound as the perfect block filler. thin it down 15%-20% and spray it on, get a 24 inch floor roller with a short nap so that you don't make it too textured and back roll it forcing all the compound into the holes in the block, it fills it in one go, then just let it go off and either spray or roll an emulsion over the top. so you do it in two relatively cheap applications rather than four or five applications of emulsion, or spending a fortune on a block filler. it looks perfect you cant see any holes or strange absorbing patterns. if you don't like taking work away from the decorator then work with him split the costs and profit.

what sort of spray gun would you need for this? is it more of a airless sprayer thing?

If it's just a small amount of breeze block ( don't have a spraying system ), would just rolling on the wet gear be ok or does it have to be sprayed and rolled?

i was thinking that but i doubt it would be the same as the sprayer would get it in every hole nuke and cranny think if its brushed or rollerd on itl be a hell of a mess if not alot of sanding needed could probably skim the wall with fast set if you dont have a sprayer?

well thats my oppinion but rob probably knows better. =]
