First coat of paint

Tmurf

Just finished plastering the internal walls of our new build.
How long should we wait to let the plaster dry out before we paint it.

Until the plaster is white all over.

We're at the first paint stage on our renovation. Some walls dried much quicker than others, depending on where they were. The last couple of weeks were very speedy.

Don't use dehumidifiers to try to dry things out too quickly or you will start getting cracks.

At the stage just ahead of you Tmurf plaster has all dried out, what's you plan cover all the walls with white emulsion paint?, will ya use a primer?, will ya use a sprayer or brush and roller job?.

I rented out a moisture metre for 15 euro for the day. Worth it i think. It had a different readings for what u were testing, wood, cement, plastered walls etc. Well known hire company so shouldnt be a problem to get one.

Mixed reviews on priming. some go for it, some dont. Ceilings or any dryling dont need priming. The sealer would be for any unslabbed blocks walls. Most recommened a light watered down coat first, let that dry and then follow with a normal coat.

There is no need to prime plastered walls these days,everything you need is in the paint. Also there is no need to thin the paint for first coat,you will get a much better finish if you use the paint straight out of the can.


I wouldnt advise a D.I.Yer to attempt spraying there house,you will end up doing serious damage to your lovely new plastered walls and new windows if you dont know how to spray! Stick with a roller.

Thanks for the advise. I havn't made up my mind yet on what we will do.
All comes down to the €€€

Don't agree with this statement, I would thin out your first coat 50/50, firstly this will speed up your application and it will save you on paint. Your arms will be pulled out of you if you put emulsion start on out of the bucket.

I'd buy a few buckets of white emulsion, while doing your ceilings do the walls in white also to give you a blank canvas.....Finish the ceilings in a slightly watered down second coat, watch for drips and snots,roller tracks when rolling and you'll be fine....

Look on the side of the bucket of paint and it will tell you to thin out for first coat...

Im painting with 15 years, no professional painter thins out the paint. You thin out paint 50/50 as you say and you may aswell just roll water on to the walls. You will also have to give it 4-5 coats.

Use the paint straight out of the can and you will get the job done in 2 coats,and the colour wont look transparent.

Michael, my brothers went this route with 3 houses, NO problems afterwards, so based on what I saw you are correct. Was there a concern one time that new walls might dry the paint too fast, therefore flaking might occur, or have manufacturers put this on the bucket to cover themselves ??(water first coat)

I'm a professional painter also with many more years experience, how big is my D**k etc....Anyway as I said if using a roller your arms will be pulled out of you using it straight out of bucket, thining the paint will make it easier to apply, plus you will get better coverage, its a first coat and not a finish.......If you would of read between the lines, coating the ceilings with white and you may as well coat the walls white also because it will make easier for walls to be finished in the desired finish/colour...

Thats what i am doing. Will the finish coat then need 2 coats over the white? or might one do it?

Basically what I used to do in lets say apartment blocks was, do ceilings and coat walls in white, cut in and finish ceilings then roll walls in wall colour, just roll. You should be able to cut in once (depending on wall colour,creams etc).

After ceilings were finished, the norm was to roll wall colour in lets say a matt emulsion, polyfill walls if any defects, bumps, holes etc. Touch up filler with matt colour, then cut it all in and finish in the same colour but in soft sheen.

Now I willl admit that watering down the first coat 50/50 can be messy and paint will be like piss, so I'd suggest thining it out just enough so it will be easy for you to apply. Skimmed walls soak up alot of paint and painting them in a neutral colour before a finished colour will help you and your pocket.

If you intend on painting some rooms in one colour then get a bucket of paint (10 litres) mixed up instead of 5 litre cans. Also a little tip, when your finished for the day, wrap up your roller sleeve in a plastic bag as it can keep moist for weeks, saves you washing out, works with paint brush also....

The only places you will see paint peeling these days are in kitchens or bathrooms that arent vented,or some people would keep a clothes dryer in a spare room and the paint would literally fall off the walls after a few months if you touch it.

The paint you buy now is light years ahead of the crap they had years ago. there has been some great advancements,there is virtually a paint for any kind of enviroment you can think of.

Just keep the job easy for yourself,2 coats on the ceiling and 2 on the walls,paint straight out of the bucket and its job done.

go for colortrend if you can afford it, or dulux or crown if not. cover any stains first with BIN primer.

you do realise applying the white paint is the same as applying the finish colour.so your just giving the walls an extra coat for no reason.its no wonder you have sore arms!

We don't know what colour the OP is going to use, but lets say Michael he was doing a H/S/L, he coats walls and ceilings in white, finishes ceilings, fills walls, touches up with white. Then OP has a lovely cream or neutral colour. Would he be able to cut in colour once and roll once over the white? In my experience he would. Well expecially if Colour Trend was used.

The original question was "First coat of Paint". Emulsion if used straight out of can will just sit on newly plastered walls, a bit of water in emulsion will let it soak in better. And people who use it straight out of can will sometimes put on a heavy coat and leave a heavy orange peel effect from roller...

Anyway goodluck OP.....

Cheers guys for the replys interesting stuff....I think just white walls all round so we can get into the place asap. I will put my feet up then and let herself colour in the canvas.

There you go, better to see a video than explaining it.. Cutting In

Btw you can't beat Purdy brushes, a good investment when doing your house, they are expensive but when taken care of last years. Actually MRCB in Thomas st/Cornmakret are doing a special, for €45 you get a double set, couple of 3" brushes, couple of 2" brushes and couple of 1" brushes...They are selling one Purdy for around €30 you can't go wrong with the set...
