I would like to repaint my hall completely white with emulsion. If cost is no issue what is the very best paint that I can use to get the very best finish?. From looking at previos posts I think Dulux trade diamond white has been recommended at around £40 per tin, or read that Little Green Paint is also very good. Any other views?. In addition, from reading the previous opinions , the very best finish is to first mix the paint 50/50 with water for the first coat, 80/20 with the second then a final top coat with the emulsion. If I'm using expensive paint I trust my first coat of 50/50 is the same expensive emulsion I'm buying and not any cheap rubbish from the local superstore?.
