What to put on newly-plastered walls? Help?

Mrs Smith

Just in need of any advice that anyone can offer. Our house build has gotten to the stage where the internal walls were all plastered nicely two weeks ago. Naturally we are wondering what is the best way to proceed- we are hoping to move in end of August.
I went into a paint shop and was told to leave the walls for six months before painting them!
I managed to get the man in the shop to tell me that there is a type of sealer that can be put on the new walls first, but unfortunately he couldn't really give me any more information.
Does anyone have any ideas or advice?
I would really appreciate it because I have no experience of this at all
Many thanks..

Six months????
I think you should ring up the technical department of a paint manufacturer.
I've often got great help from a paint company in Celbridge who make paints.....

If you want you can apply a watery coat of polybond first to seal the walls.

Just get a tin and literally dump it into a bucket of water. Mix ratio about 5/6 parts water to one part Polybond and lash it onto the walls.

I'd put a heavier coat on in kitchens and bathrooms to stop paint peeling in years to come.

Any reputable paint shop will supply you with sealer which can be brushed on liberally.

An old painter friend of mine once advised about putting on wallpaper paste which acted as a sealing coat. No idea how good it is but I did use it on my own walls many moons ago but I didnt paint them for about 4 months in any event so I cant really say if it worked or the walls just dried out naturally in any event.

Half a cup of polybond mixed with the paint

Once the plaster is defnitely dry you put on a coat of Polybond, it is just like painting with water. If this is not done the walls will absorb the paint and you'll end up having to put on about three coats on walls and it can still be patchy.

Check with your local DIY (eh not the one who said 6 months) and they should be able to advise you.

No no no......Polybond is to be used if you intend on papering the walls, or its main use is to seal old walls before any preparation work is to be carried out. but a coat of watery emulsion will do this also. As for sealing with wallpaper paste this was also to size up the walls years ago before wallpapering.

Wallpaper paste can actually eat/burn into emulsion, an example of this is, if someone is papering a room and the overlap hits the ceiling and wallpaper paste is left on ceiling and not washed off, over a time the white emulsion will crack and blister...

Those the above come to mind to anyone?

Best bet is to get a couple of buckets of white emulsion (Good brand) and mix it 50/50 with water and get a roller pole and sleeve and roll onto walls. Or better still get an airless spray gun from a hire shop and you will easily do whole house in a day. But this will use alot of paint, so be prepared.....Coating with white gives you a blank canvas to work off...

Many thanks to everyone to replied to my post re the newly plastered walls. We will check out the Polybond, especially as it was recommended by most of ye.
Thanks very much again

My house was plastered 6 weeks ago and there is no way that the skim is any where near dry enough to paint yet. It will need at least 2 more weeks.
I had a painter in yesterday to give me a price for spraypainting the undercoat on the whole interior and he advised me that to do it too soon, even if I do seal it, will mean that a lot of paint will flake off in the future.

He advised me to get the heat on and the sewerage hooked up and any other work that needs doing while I'm waiting for the plaster to dry.

Studded walls are fit to paint, but the block walls are not dry enough yet.

You will know by the colour of the skim. It needs to go grey / white. It will take at least 6 weeks drying no matter what you do.

Mrs Smith

Hi Rellig,
thanks v much for your info, will definitely make sure the walls get at least six weeks to dry- the weather has really been helping because almost every day we can see the plaster slowly turning paler and paler.
We can just crack on with all of the other bits and pieces that need to be done.
We heard of someone who painted too quickly and was looking at a huge bill to rectify the walls because they needed to be sanded down and sealed properly all because they were painted too soon.
Many thanks, and best of luck with your own house.

I was considering spray painting the interior of the house myself when the time comes. Why use a airless spray gun as advised above?

spot on mad m, 100% correct

i got my place sprayed - a great job - can't remember the cost exactly somewhere in the region of 750 to spray the interior twice - worth every penny!!!

My spraypainting cost €300 for a double coat on all walls and a treble coat on the ceilings which are now finished. The house is 2000 square ft. It took €200 of paint also. Great job. Agree, it was worth every penny.
