Hi all, a freind has got a newly plastered garage conversion. Ive offered to paint it for him?? I thought id try thinning the matt emulsion down and spraying it over the fresh plaster as a mist coat? walls & ceiling. then spray around the awkward bits and roller the main sections with a second coat. a freind told me Beaver emulsion is best quality /coverage. how long before recoating ? could I finish the whole job in a long day, glossing skirts&arch`s ,doors last?
