Mixed paint - a question for the professionals.

Yes, if you wanted a specific colour. Dulux color on shelf is maybe 45 but if you pick plain white and they mix to colour spec think it's 7/8 euro cheaper.

I used to get ccolortrend colors mixed in Dulux matt.

They put a stop to it as colortrend reps realised the colours in machine were emptying faster that their white paint was being bought.

It's probably a Dulux paint machine.

Dulux have an app with 1200 colours and you can get any colour mixed up in a shop that has their paint machine.

They also have that colour match scanner that will give you paint the same shade as whatever you scan.

You can add stainers to a finished paint.
The only issue is that there is a % you cannot cross as it affects the durability of the paint. There is a balance of driers, extender and stainers to be aware of.

A lot of paints will separate after lying around for long periods but I just bend a metal coat hanger into the shape of a W and fit both loose ends into a power drill and just mix it back and most of the time it's as good as new. I know certain paints once gone bad there is no coming back though.

Are you saying that you painted it on Thursday and your wife wiped it on Sunday?.

If that is the case ,then the paint should have been well dry.

What brand of paint and what finish did you use. Was it a Matt finish by any chance

Is that area under an extractor fan?.

It can be hard to see, but make sure the wall area is scrubbed clean of any grease and fully dry before you repaint, otherwise the new paint simply won't adhere well as has happened here. I use warm water with sugar soap for preping kitchen surfaces, rinse afterwards with cold water and allow to dry. Once you've repainted, avoid using the cooker for 24 hours to give the paint a chance to cure.

Having painted wall areas in close proximity to hobs or ovens is always going to be problematic because of the constant steam and grease. Thats why I think most folk tend to opt for an easy to wipe backsplash of some discription . . be it marble, mirror or tiles in these locations.

Basically Dulux have so many colours in their range a shop can't stock them all. It would take up too much space.

It's far easier to stock a selection of the most popular ones and then to mix up the rest using one of their machines on site.

Scrape it first (there may be an invisible layer of crud), then sandpaper then brush down. Wipe with a damp (clean 😀 lint-free) cloth and let it dry well.

Just a DIYer here.

A splashback is a good idea. It will cover the blemish, and be much easier to keep clean.
