terribly patchy walls after several coats dulux matt - sol?

[muncierobson]

The walls in my newbuild flat (2009) have had several coats of dulux polished pebble matt paint, in some parts they are incredibly patchy - when looked at head on, the colour covers the wall but uneven texture means they look very patchy from even a slight angle in daylight.

I had painted them twice myself, and have just had another couple of coats from a painter (in autumn and i never have heating on, the flat is always well ventillated)

Would the best thing be to sand down the wall and repaint? The worst patch is a 1.5 x 1m area next to a sunny window, would i need to sand the entire wall or could I just sand the really bad area?

If I used a sanding block, should I use in circular motions?

I am so frustrated as have spens £££s on paint and now on labour and still have a patchy finish. I cannot stop looking at it!

Any suggestions?

Was the Dulux paint retail or trade??. Personally I don't use Dulux any more for the uneven coverage recently though the trade stuff is better than the retail. I would prep the walls as required and use Johnstone's cover plus vinyl matt. Just completed a similar job after they used dulux retail cr*p. 2 coats of the cover plus sorted it. I'm interested on what your decorator thought of this?
Also Gliddens paint is good which can be bought from your local dulux centre.
If your walls are smooth, use a short pile woven roller http://www.decoratingdirect.co.uk/viewprod/c/CDDSS12SP/

If the surface has any roughness use a medium pile roller http://www.decoratingdirect.co.uk/viewprod/c/CDDSS12MP/

Keep away from the miro pile rollers these tend to leave tiny air bubbles.

Many thanks for you comments and suggestions re my patchy paintwork. As its a large area - living room and kitchen off, I cannot have everything repainted with a different paint. Would you recommend sanding the wall and repainting? I am convinced the patchy effect is where the light is catching the uneven surface, even tho the wall is thoroughly covered in the dulux paint. yes it was retail, I'd assumed as the walls were new (and smooth lol) I could paint over the magnolia myself! Ive done minor plumbing and electrical jobs, im so MAD i've been beaten by some dodgy paint! I think I had made the uneven surface worse by attempting painting it with those ridiculous paint pads - I will NEVER use one of those again!

Ok if the walls are uneven then a matt finish is usually what I would go for as it won't reflect the light as much and show uneven blemishes. We also go for trade as this is usually a thicker paint and better opacity and can be thinned slightly. Anyhow give the wall a light sand with a fine paper and wash the wall with a mild detergent to get all the grease/dust off. Read this

Thank you so much - this sit/forum is helpful!

I cannot afford/time to repaint whole room, will consider trade paint next time!

The worst part is by a window where direct light falls - considering Venetian blinds to soften light. The fault is both uneven plastering and poor coverage the first time I painted.

Would it be worth a try to sand the affected area and repaint just this area? (Have sufficient paint left)

Many thanks for ur advice!

Please tell me, you did thoroughly mix the paint before use?

The pictures you posted are not very good, but a possible cause of patchiness would be paint that isn't mixed well. If the paint has stood around for a bit the colouring agent does separate and hence the need for a decent 5 minute stir before you apply.

Sadly batches do have slight difference and if you bought tins at different times that might explain the problem.

if the plastering is no good no matter how many coats of paint you put on it will never look good ,cross line it and repaint best way to go...
