I've never had a problem with undiluted Crown emulsion on newly
plastered ceilings. I have had trouble with Dulux though.

What sort of trouble Stuart? Did it fall off?


Yes, the roller was pulling it off as fast as it was putting it on. It was
just too thick basically, and it seems the viscosity was created by
entraining cheap (i.e. heavy) minerals. It certainly was non-drip but at
the cost of not performing well on porous surfaces.
OTOH the last lot of Crown I used was thinner and went on like a dream
straight from the can. The own brand B&Q was much the same IIRC.
The practice of thinning emulsions is not a good idea IMO, despite what
the manufacturers say, because the added water isn't truly incorporated.
Think diluting custard :-)


Hi again folks! I'm in the process of painting my son's replastered
ceilings (all artex'd and he couldn't stand it!). I'm doing it for an Xmas
pressy, 'cos I've got plenty of time and no cash!! ;-))

I tried various ways, brushes, pads, etc. The plasterers suggested diluting
the first coat of emulsion and then a couple of coats of "normal".

I found, after experimenting, a good roller with a *foam*-sponge
roller-thing (whatever it's called!) - foam-sponge works the best, trust me.
Extended handle, standing on the floor. First coat diluted about 30% or
more with water, mixed well in a paint-pot (with a stick, that's all...and
don't need to be exact, just water it down some) first, followed by 2 normal
coats. Cover everything with sheets, etc. and wear a hat. I'm managing to
do it making very little mess, using Crown non-drip b/white. Don't overload
the roller, not much spray, and only got one huge gob on my nose!!

All the coats going on a treat, and cover when dry is very good.
Good luck!!!
