Emulsion ceiling after burst pipe

tommie1shunt

We had a burst pipe in September, the front room ceiling took the brunt of it and has light brown patches all over it (Artex ceiling) We have a dehumidifier running 24/7 since the burst and we want to emulsion the ceiling now. Looking for recommendations for a 1 coat solution and preferably something that does not drip. Any info appreciated

There's a sealant aerosol spray you can buy to stop the brown stain coming through into the new paint.

Can't remember what it's called, but all DIY sheds will sell it.

You will never cover it using emulsion paints.

No matter how many coats you put on the stains will come through unless they are sealed.
There is loads of products on the market, but the cheapest and the best option IMO and you will probably have some lurking in your shed, is to use oil base undercoat.
Pour a little undercoat into a utensial or old container, add a capful of white spirit, give it a good stir and brush that on the stains.
When UC completely dry, then go over the stains first with your slightly diluted emulsion, do this twice, then do your emulsion coats as normal, the stains wont bleed through.

Remember, it has to be oilbased UC, or eggshell, dont use gloss.

The product you need is called Zinsser bin its an undercoat/stainblocker about £13 B&Q sell it .
Its what the pro's use even used on smoke damged surfaces to seal in the soot/odour

I've heard from several friends that polycell "stain dtop" or stain guard" I think is the best thing to use. I know alot of professional contractors for insurance companies also use this. It is in an aerosol spray and is like a white paint. I know a few peope who did get away with 1 coat but it does purely depend on the level of staining.
