I have painted a wall using Dulux 'Once' emulsion and it has gone all patchy - any advice please?

I painted a wall using Dulux 'once' emulsion but it went all patchy. I repainted using a base coat to eliminate the patchiness an again applied another coat of the emulsion. I came down this morning to find that the paint had dried ok except for a bit towards the top of the wall which I rollered over again. Unfortunate whilst I was doing this a splash of emulsion landing on the wall and where I rollered over it it has gone patchy again! it is only a small patch and so I am reluctant to repaint the whole wall yet again. I have painted a little polycell base coat over it with the intention of going over it with emulsion but will this work? I don't understand why this has happened as I have used this type of emulsion many times before. Any advice would be much appreciated!I have painted a wall using Dulux 'Once' emulsion and it has gone all patchy - any advice please?
once is a funny paint!


when you put it on you need to leave it alone.


if you try to roll over it straight away it will pull off


just lay it on and leave to fully dry it will even pull off at the tops if you try to cut it in too soon.


apply a second coat on the second day if possible and it will go on and cover great.


once is not once at all it will need 2 coatsI have painted a wall using Dulux 'Once' emulsion and it has gone all patchy - any advice please?
When you say you splashed the wall and that went patchy, it would have just needed longer to dry out. On that basis perhaps the patches are areas of wall that make the paint take longer to dry out. If not, contact Dulux.
This is a long question for an strait forward answerer, make sure it's fully dry before you go over as it will dry at different shade to when you put it on. It's not as ';once'; as they claim.
hiya caz, sounds like you did not stir it up enough,that is why it went patchy.
do it again
first off avoid any ';gimmick paint'; all the 1 coat non drip etc are rubbish. What was the substrate you painted like, i wonder if you have a lot of filler as this can effect the even porosity of a wall and leave the paint patchy. If this is the case another coat will do it and in the future apply a mist coat (water down paint 50/50)


or could just be did you give the paint a really good stir right to the bottom of the tin before use and again when you thined it?


hope this helps
