This is for a recently skimmed, plasterboard wall and ceiling, in an Kit/Dining/Living, open plan extension.
So, from doing a bit of my own research I now know that Contract Matt is normally only used on fresh plaster, and is breathable so allows the plaster to continue to dry out, but is not breathable or wipeable so is not normally a finish coat.
I had originally planned on using the Cheap(er) Leyland Trade Contract Matt as a mist and base coat, then doing a final coat of Leyland Trade Hardwearing Matt or Acrylic after everything was fully dry. My reasoning was to reduce the amount of more expensive paint.
However, in a Q&A I read, Leyland seem to be effectively saying that there is no point in this because the substrate will still be absorbent and the first coat of the Matt/Acrylic or primer will still need to be thinned down and applied as a base coat, before another two full coats.
My cynical side wonders if this isn't a ploy to sell more of their expensive paint, but I wondered what those who actually do the job think about this?
