How to treat the walls after stripping the wallpaper off?

[z3usx]

I've just stripped one of my rooms of its wallpaper and washed off hopefully all the wallpaper paste, however is there any thing else i need to do i.e. seal the wall up as i used a steamer.

The wall was painted before wallpaper was put on and there was some damp stains from when the roof was leaking. At the moment the wall after being washed is a bit powdery when dry but i assume this is the emulsion on the wall.

Is there anything i can do to stop the emulsion on the walls being chaulky and stop the stains coming through the new coat of paint and seal any pourous plaster as well all in one go?

Thanks

Diluted PVA is the standard way to seal up the porous and chalky stuff.
You can get 5l from a builders merchants for less than 1l in B&Q.
Do one coat of 1 part PVA to 5 parts water, then one coat of 1 part PVA to 3 parts water. Leave to dry between coats, it only takes an hour or so.

Diluted PVA is excellent for chalky, flaky paint, it stops it from flaking.

As to your water stain, whack some oilbased undercoat on the stain, let it dry, then carry on with your emulsioning.

What do you intend to put on the walls now they are stripped?

In that case once the walls are nicely bonded down then id reccommend you line them beforehand
