does emulsion paint cover vinyl silk paint?

Vinyl Silk is an emulsion paint. You get Matt or Vinyl silk finishes of emulsion

A couple of coats of white emulsion will take away the dark colour then you can paint it to your liking

Yes emulsion will cover silk paint as silk paint is an emulsion. But first I would cover the walls with a base of white Matt emulsion, this will give a better base for your light coloured emulsion paint. As this is a children's bedroom I would suggest that you get a vinyl silk emulsion (silk emulsion is wipe-able with a damp cloth) as the paint to go over the walls where you have painted them white.

I do hope that this is of help to you. If you use undercoat as someone has suggested it will take a while to dry and will make the room smell for a day at least as undercoat is an oil based paint, and this is totally unnecessary.

Yes but having two children of my own, I'd recommend sticking to a vinyl silk emulsion - it's much easier to wipe clean!

Unless you go over the walls with white emulsion first then the colour you paint on the wall will always come out as a darker shade.

Yes it does, but you will need 2, 3 or even more coats of emulsion and even then the darker colours will bleed through.

Yeah no problem wil just need 2 or 3 coats to cover it.

hi yes it will cover may need more than one coat ive done it many times

it will but you will have to put an undercoat on first
