I recently had some walls plaster skimmed. I allowed the plaster to dry for
1 week. I noticed then that I could see an outline of the corner beads
(galvanized thin coat type) but assumed that was due to the thinness of the
plaster.

I have sealed the walls with a 1:5 water/Gripfill PVA solution and applied 2
coats of B&Q "Colours" vinyl matt emulsion paint, allowing each to dry
thoroughly. I am disappointed to find that all of the beading shows through
as a lighter colour than the rest of the paint.

I reckon that I need to somehow seal the beading again, but what should I
use?

Thanks.

The plaster should not cover the rounded corner of the strip -- it
is there to give you a nice consistant rounded corner.

Are you sure it's not just the change in angle?
Or maybe the paint coverage is inadiquate?

The corner edge was not plastered and it was the whole 1" wide bead which
showed through the paint. I emailed the "Brewers" (trade decorating
supplies) website and received a very helpful reply.......

Never seal a newly plastered wall with PVA as is prevents the vinyl emulsion
from curing properly. The best thing to use is watered down emulsion paint -
which is what I always used previously.

Brewers recommended that I use a stain block ("Zinsser BullsEye 1-2-3") over
the affected area. One coat of that followed by a further 2 coats of
emulsion has solved the problem. Phew!

Paint the beading with a near matching oil paint first.
