Hi really hoping somebody can help me. Our house is to be smooth render finish as per the planning permission, i just noticed last night that the plasterer has done a finish that looks like something on an old house, it looks like stipple, he does this with a sponge. He said we should have said at the beginning we wanted smooth finish. Luckily only one side is done. He said there is something you can get that can go over the gritty finish, granular (?) comes in a tub, he couldnt remember name of it. Would anybody know.....
