OK, I've had new plaster done, 50/50 mist coat of Dulux Supermatt and then straight on with F&B Modern Emulsion. The result is great, but I'm not entirely keen on the slight 7% sheen of Modern Emulsion. I have the same colour in 2% sheen Estate Emulsion and was wondering if I can go straight over it in that. I intend to rub back a tiny bit with fine sandpaper, but other than that are there any likely issues doing this? Is Modern Emulsion like a vinyl silk in terms of its components?
