Painting over water damage

Hey all,

Heading up to brisbane Friday to do a small Reno on an IP. It has had a leak in the past and thus water stains in numerous areas of the ceiling.

Just wondering what sort of prep I need to do so it won't bleed through the new paint job? Searched it but got conflicting views.

Stains are that dirty brown colour.

Cheers

Dan

 

Zinsser cover stain is good. In general There are water, oil, and spirit based paints depending on type of stain choose the right type and you should be fine.

 

Thanks heaps!

 

Prolly look at using a bleed sealer to stop the stain reappearing.

 

Hey Scott Is that just a special undercoat or something? Similar to 3 in 1?

 

3 in 1 is just a primer, sealer, undercoat. A specific stain/bleed sealer is what you need.

How long are you in Brissy for?

 

@dan2101 Specially designed undercoat: Looky here

 

Zinnser oil based stain block undercoat then ceiling white over the top

 

Awesome super helpful as always guys, thanks.

@SK Investments I arrive Thursday night and hoping to paint, carpet, blinds, fix roof leak, tidy yard in about 10 days. Should be right hopefully!

 

Sounds like my property, I'm heading up to Brissy next week sometime to do some work.

 

Nice where's your property at?

Any idea where you're getting your carpet/blinds from? Solomons seem really cheap but haven't checked the quality yet.

 

Fixing the leak and getting it gyprocked would be the way to go long term. Might be able to find a reasonable quote - although my last quote was too high so I just painted. No leak though, just really flaked. Once the moisture gets in, really needs to get replaced.

 

Yeah azazel definitely going to fix the leak. You don't reckon it will come up ok with a stain blocker and coat of paint?

 

Give it a sand, and if not a nice smooth finish then skim it with topping compound, sand and feather edges, then undercoat and paint. No need to re-gyprock it.

 

Cheers Dave great advice. I've got some leftover topping compound so should be right hopefully.

 

It could, if it's just discolouration on the surface, but maybe not if the water has been in and it's swelled.

 

Is this for your Runcorn property?

 

I've got a similar problem at my PPOR. The leak in the roof was fixed a while ago. I have to do something with the brownish mark on my ceiling. I assume I'd have to undercoat and paint the whole ceiling, not just the affected area.

 

Depending on the ceiling damage you can brush on a sealer undercoat then roll the affected area and run the roller dry to blend it with existing.

Best to roll the whole ceiling of course but an ok solution if you need to otherwise roll a huge area for a small area of damage

 

Hey Quop nah my Keperra property. Runcorn next time got great tenants there so no rush.

In the end one small section had to be cut out and re sheeted. The rest I skimmed with top coat (had to sand back flaking paint) then 3-4 coats of zinser then painted. Came up a treat.
