I recently moved into a house that had magnolia matt emulsion on its
plaster walls, and I painted over it with Dulux Once single-coat matt
emulsion. I used a fleece roller.

The result is very patchy: looked at head-on it's OK, but in glancing
light, there are patches of a rougher texture which appear darker than
the rest of the wall. I didn't realise it was the texture that was
making the difference at first - I thought it was uneven paint
coverage - so I tried going over these patches with another coat,
using a brush, and this made things even worse.

I since found that there have been a lot of complaints about Once, so
I'm going to decorate again, this time with two coats of ordinary
emulsion.

The thing is, being an asthma sufferer, I'd rather not sand if I can
help it (I notice that even sanders with good filtration systems only
claim to catch about 85% of the dust). Just sanding the rough, darker
bits might not cause my health much of a problem, but I think that if
I did that, the finish wouldn't match the surrounding area. so I'm
afraid I might have to sand the entire wall if I sand at all.

So I'm wondering if there's anything I can do to disguise the uneven
texture prior to repainting without having to sand. Thanks.

I have a feeling the dust from sanding won't aggravate your asthma. My mum is severely asthmatic and the slightest bit of domestic dust has her choking. But building dust is very different. I sand and drill and cause clouds of masonry dust around her and she's happy as larry.

From what you have said (not looking head on etc) this problem is
perhaps not as evident as you seem to think. However I feel you will
not be happy until you do sand these walls .
To protect you from the dust (due to your asthma) I think you need

or similar. I do not feel you have to go much more technical than this
as it is only to protect against dust not fumes


Why not use a good filtration system sander (85%) and a nuisance /dust
mask this should give you no problems (remember googles and possibly ear
defenders and gloves for prolonged use).

If you are deadset against sanding perhaps lining paper then paint on
top of that.
