New Plaster and Matt Emulsion

Is it a disaster using matt emulsion on new plaster?

Just water the emulsion down. It will probably say this on the tin..

When I worked in B n Q years ago the paint department was run by a guy who worked for ICI years ago

Anyway I digress - he said to buy the cheap white paint, water it down (3 parts water to 1 part paint) and put 2 - 3 coats on :beer:

I think that would be too thin to stay on the brush. I would vote to swap the proportions round and do 2 coats

These were the proportions I used and all has been fine except in the shower room ehere it has all peeled. So be extra careful if a bathroom and water down more.

The recommended emulsion would be "contract matt" or "obliterating emulsion". There are various names but the product is the same. For example Leyland make both Leytex and Contract Matt - the same products for the same use.

To answer your post, the contract matts have both a lower vinyl content and a higher filler content. This means they fill imperfections in new plaster (less need for filling and sanding down) and also allow the plaster to dry out. If your plaster is well finished, and your walls have dried out, it is not a disaster if you used vinyl matt instead or obliterating/contract emulsion.

we have done 1:1 ratio then a top coat and it looks great.

Wickes Trade Paint for New Plaster, breatheable, comes in 10L tubs Brilliant White or Magnolia - fantastic stuff.

depends on the paint, but that is too thin. we made this exact error (too thin) and the result was that the finish paint didn't take at all. ended up having to strip it all off and start again.

in the end, we bought contract matt emulsion, and watered it down 10% as per the instructions on the tin. went on great and the finish cost(s) adhered properly.

basically, get a decent trade white emulsion and water it down according to the instruction on the tin (probably 10%).

Trade emulsion comes in two colours, white or magnolia. It is aimed at new plaster in new houses and helps explain why these are always white ceilings and magnolia walls!

There was a time when Crown Trade Centres did Covermatt - their contract emulsion- in other colours. I can recall buying pink, light green, and pale blue and some other colours were available. These were great for giving a new home a wow factor compared with a standard mass built new home. OP, or other forum users, may wish to explore this - I do not know if they are still available.
