I've recently had a room skimmed, and will mistcoat with Supermatt when it is dry. Although the plasterer has done a nice job, there are slight blemishes here and there which I will fill with easyfill probably. Can anyone tell me if I should mistcoat first, then fill, or fill then mistcoat? Will it be ok to very lightly sand too? Also, while I'm on the subject, someone told me that a pva and vinyl matt mix would be just as good for my primer. Is this true, or should I just stick with the normal watered down supermatt to be sure of a good primed surface? I think of myself as pretty competent in most things diy, but just want to be sure that's all as I want to do things the right way for the best results. Any advise will be appreciated. Thanks
