Which paint to buy? (Painting 3bed house)

[WeAreGoingOnABearHunt]

We are just going to start to paint the walls and ceiling of our 3 bedroom house. It was last painted when it was brand new (before we bought it) 7 years ago - magnolia walls and white ceilings. The decorators have said to me to just buy the wall and ceiling paint (not to worry about primers, etc).

With good intentions and figuring this would be the easiest purchase ever!, i wandered on to the dulux website to buy it and got gobsmacked by the amount of choice (ignoring the fact that I am not changing colour of anything!)...

So... Advice please!! For a novice :) we have a dulux decorator centre literally 5mins down the road from us.

Which paint to buy?
Dulux trade or retail? (I read somewhere that some dulux trade paint is meant to be thinner as new plaster needed several coats or somethings like that... But in other forums, they say dulux trade paint is fine? Given we are just repainting the wall and ceiling the same magnolia colour with no primer- does it matter dulux trade or retail are used?) Sheen, eggshell, silk, Matt? Will I need to use special kitchen paint and bathroom paint? I assume so as both our bathrooms have no windows and one of them has mildew (I think) which will need treating...

Thank you for any advice!

Yes, bathroom paint for sure. Damp seal needs to be applied first tho

Dulux trade is thicker. Decorators tend to water it down as they go. If it's walls you'll prob be best off with Matt finish. But why are you sticking to magnolia??

Damp seal? Never, ever heard of that. Your bathroom is already painted and you are just re-painting what is already there all round the house from your other thread?

It's more expensive, but trade paint ime gives better coverage. There is no need for thinner paint as the plaster has already been painted. Yes, bathroom paint does the job and withstands the moisture, but it does have a sheen rather than being matt.

I would just buy large tubs of pure brilliant white and magnolia matt emulsion in your position.

Damp seal by rob seal, very popular, does what it says on the tin!! As there is an existing problem you need to remedy that and then apply damp seal to prevent further Mould growth. It dries white but you can then paint over it

For the mildew, it would be more beneficial to sort out ventilation in the room - so fitting an extractor if there isn't one or making sure you use it if there is one. Just painting over mould and mildew is a recipe for disaster. Make sure it is removed before any decorating starts OP.

That's what I said.... Remedy the problem. But damp seal is specially formulated to prevent the spores growing back. Then you paint over it. ( I work in this area) bathroom paint alone won't be strong enough for established mould

Good luck, will all be worth it once finished!
