[rocketmanbkk]

Hi Friends

Got to paint a ceiling after water leak, usual brown stain.

Anyone know the best stain block the actually works?

It's in a kitchen so white emulsion.

Cheers

just keep slapping on the emulsion is my method

Really? How many coats? It's a bad stain. I don't wanna keep going back.

I'm no decorator! I've heard you need an oil based product then slap on the emulsion.

2 coats of Oil based undercoat first I believe.

Ok, Thx.

Nah, use a proper stain blocker every time.

Ronseal? Paint on or spray can? I'll give it a go

 

[tamz]

Pay a painter to do it. Much easier and its his problem if the stain comes back.

The spray tuff is rubbish. This works but usually needs two coats. Doesn't quite do what it says on tin.

Don't waste your money. I'm with RPM, oil based undercoat is quite sufficient.

 

[Mike Jackson]

I normally use the aerosol stain block. few coats and it's done. Quite often blends in with white emulsion as well.

toooooorisky oil base undercoat with emulsion on top, for the sake of a few quid....nah LOL.

No risk at all, recommended method by Dulux. Or at least is was once before stain stoppers were invented.

have just finished a mega job I have been on with all summer, when the decorators came in (professional lads, 4 off them )
Dave the owner had marked all the emulsioned walls with a blue permanent marker, there were water leak stains on both the kitchen and lounge ceilings. No under coat, just stain blocker .......................... I rest my case LOL

 

[lame plumber]

used to be aq bit of eggshell to do the job

 

[rpm]

I`m fast coming to the conclusion that Stain blockers are the old oil based undercoats but cost more. lol

Coat of eggshell and then emulsion over. Never had any problem at home. If its at a custs then its a decorators job.

I would cover the stain with some oil based gloss paint
then go over it with the correct finish paint. This will work
until 'the cheque clears' its a short term fix CHK

Thanks for all replies & opinions.

Almost a "What boiler is best Q" wasn`t it rocket? lol
Be sure to come back and tell us what you did and the result mate.

 

[rocketmanbkk]

Will do, may need a variety of them all!!

it is ok to use undercoat as it blocs it coming back, however it gives a shiny finnish, that means you have to repaint whole ceiling at 3 coats of touching up, looks odd, stain blocker as above pic is much quicker, dries in half hour and can paint straight onto it, 2 coats and your off!!

All depends on customer though as most will want whole ceiling repainted as it will look different otherwise

Stain block aerosol for me. 2-3 coats and 2 cotes of emulsion on top. I use aerosol because it drys very quickly and I dont have to wait around to top coat.

As in update on this one friends-

Spray stain block - tried 2 £8 & £13 per can. Didn't work.

Crown stain block - rubbish

Oil based undercoat - seems to have worked. Put a coat on, left it to dry, emulsion x2 coats & fingers crossed the ceiling looks good.

I'll update with any change.
