Painting new build

893bet

I want to start painting the interior of my new build. My plan is to give it 2 white undercoats then employ a professional to apply two finish coats and sand and fill walls etc.

What type of paint should I use for the undercoat? Is cheap white Matt emulsion fine?

One tip from doing it myself a few years ago, is make sure there is some form of heat in house as the paint will run on very cold walls.

Don't go too cheap. Remember, it is going to be the foundation for whatever is going on top of it.
Firstly, ensure you scrape all walls thoroughly to remove any spatters of skimcoat etc. Then thin the paint with water before applying.

you should contact your local painter first.

you might more harm than good with poor application of first coat.

berger superflat white matt is reasonable cost & good quality paint.

Totally agree..Just spent a day and a half fixing up a botch job started by one of my customers.

I think I have decided against the DIY job inside. Will paint the outside myself instead!

If the first coat is not right, it will never be right.

Spray a new build every time. Fast, cost effective, great job.

I have priced spraying of interior as it stands.
I have one question still.

Am I ready for it?

The house is plastered inside probably 4 months so well dried out. Finished floor is down and 2 years +

Heating was only switched on last week and will be have been on roughly 2 weeks at my proposed painting start date. Am I good to go or should I be waiting for a few more weeks with the heating on before painting? Would like to get it down before the tiler starts.

Without seeing it I would say you are good to go. Any salts showing on the plaster? A white efflorescence/chalky dust on the surface?
If so, wash off now with a diluted vinegar solution or buy a treatment for it.

I would say its a little dusty looking? but not much. Does this need to be washed off?

I googled and it looks nothing like this below but...?

Sounds like the perfect time. Plaster is long dry, and before the 2nd fix and finishing begins, tiling, kitchen etc

Those are extreme cases.
What you are looking for is build up of salty/chalk like white powder (it's the salts coming out in inferior materials)
Usually I would use very worn or fine sandpaper and sand (just a very light rub, you don't want to scratch the plaster) the entire walls quickly, dealing with any plaster splatter and tidying up the edges where wall meets ceilings etc. (You could leave this until after mist coat as that will show up imperfections better)

If it is general all over dust just brush off and continue with watered down coat of emulsion (mist coat), thickening the mix with each coat (typically 3 on new plaster) until satisfied with finish.

There is no build up like that. At most just a white dust like flour if you rub a wall.

The painter has mentioned sanding as required between two coats.

Prices I have gotten range from 1k to 1.3k including materials for 3 coats to ceiling and two coats to walls. All white. 2200 sq feet.

Went with a painter from tradesmen.ie in the end. Very happy with the spray job! Fair glad I didn't attempt it myself now!
