Matt or Vinyl Matt for mist coat

Using vinyl Matt can be a problem when applied as mist coat and never use vinyl silk. Matt emulsion is best as long as you thin it out to 20% clean water 80% paint. Some of the cheaper priced Matt emulsion paints are very chalky and will rub of when sanding between coats. Trade paints ( Trade Matt Emulsion) have stronger bonding properties and are a far better material The word trade is usually on the tin and they are more expensive, but trade paints are better in almost every respect. They cover better , go on easier, go further and are more hardwareing

matt is much better to use for a mist coat as vinyl matt has vinyl in it which gives it a bit of a shine and will result it the paint drying with a skin that can peel off bare plaster.

Matt is the better option as it has more chance of penetrating the plaster, mixed 50/50 with water to apply (can be a bit messy). I'd usually sand down the plaster work before hand, brush off dust, then wipe with damp cloth, and apply mist coat. Allow as long as you can for mist coat to dry before applying first paint coat. Paint for mist coat can be any sort of budget matt emulsion. Hope that helps.

Always use contract matt on new plastered walls. Thinned down as per instructions on tin.this allows crystalline salts that's in plaster to dry out, then wiped off with a damp rag prior to applying finishing coats.vynil Matt, and silk contain p.v.a.polyvinyl acetate which is a form of plastic which stops the salts drying out of the plaster and and impeding the adhesion of paint to the surface. I hope this has been helpful for you.
