Is within anything you can coat matt paint contained by to build it washable? I have a moment ago painted my walls in crown matt...

I have a moment ago painted my walls in crown matt and immediately everytime the kids touch the walls they leave greasy fingerprints on them that will not clear up off. I hold looked to see if they do the colour I have contained by easyclean but they don't. Is there any other opening round it.?
Every lacquer or varnish will leave your matt finish shiny. The one and only one worth considering is Polyvine, an acrylic varnish, but even that will put a sheen on your matt paint and it is expensive.

It would be cheaper for you to repaint with Vinyl Matt emulsion which should be wipable. Use Dulux.
Please dont paint your walls with grease based varnish ! It'll impose you problems in the long residence.
You can buy an emulsion glaze (clear) to protect your walls its acrlic base, and very tricky wearing, Johnstones sell it, I belive crown may own their own version too.
For adjectives referance, there's some great washable matt emulsions on the market in a minute, again there acrilic base, and well worth the money
Good luck
Answers:    I think the best piece to do is re-paint using a soft sheen or vinyl silk, it is a lot of work but will recover you time in the long run and it will be unproblematic to wash and the room will look nicer for longer. Using varnish will spoil the look of your paint work and accentuate the greasy marks that are already in that!
You could try using a Matt Vinyl.Its washable...Failing that.Have the colour you entail mixed is the store where you bought it.Most of the bigger stores will do it for you, also look at your local trade centre, they will do it for you..
