Could this be used to protect a painted floor?

Yes. I have finished off three painted floors with this varnish. Great protection and ten months later they still look great with a good shine.

Can this be used over brillant white vinyl matt paint on a MDF door.

I cant see why not it's great stuff, I made table matts and used it on them, they have stood up to a lot of abuse with not a sign of scratches. If it were me I would give it a go

Can this be used on chalk painted air dry clay coaster? Will it offer some heat protection and not be tacky as I don’t want the mugs to stick to it.

Hi Nicola Haven't used on clay but have on decoupage coasters and tray , used 2 coats I waited 24hrs before 2nd coat , it has heat protection. Hope this helps, Patricia

Can i use this dead flat finish over existing polyvine satin finish without sanding down?

I think so - the application instructions don't mention denibbing between coats, however, I used 2 layers of satin on my kitchen worktop, then used the dead flat finish on top, but I did sand down using a high grit sandpaper between coats just to get a smoother finish.
