Where To Find/Buy Mould-Resistant Non-Drip Ceiling Paint?

[JetsetBkk]

I'm looking for something like this:

 

or even a spray:

 

My bathroom ceiling looks disgusting.

 

Funny how the edges don't have any visible mould.

I would use TOA contact primer, and follow up with TOA SuperShield semi-gloss paint. Be advised, the contact primer is drippy...

Hard to tell from the photo but, if the mold has penetrated the gypsum, it may be just a matter of time before it breaks up and starts falling out.  If that is the case, painting will just be wasted.  Maybe time to replace and check for moisture ingress.

It does not look like mold to me.

???? Should I be worried?  I'll post a close-up picture later - on my way out now. Like the ceiling.  

But funny how the edges aren't affected - can still see the brush strokes from years ago (10 - 15?).

I think I'll  get someone to get into the roof space and have a look from that side.

 

- I can't get up the tiny hole in the breaker room cupboard.

I would not be worried, but I would knock around and check for soft or wet spots. 

 

The edges have heavier pant because they are cut-in with a brush and rolled over. The corners also likely have joint-compound which is easier to seal than the paper on gyp-board. You can probably see nice spots where the nail/screw-heads were filled also. 

 

If I had to guess, I would get it's discoloration bleeding through from the moisture in the bathroom. Do you take hot showers< Where the paint is thick, it does not bleed through.

 

A coat of that TOA  Contact Primer should seal it, I've used a good bit of it and it's great. Be advised, it is not water based so use a deposable brush. I do not roll it, I use a 4" brush. It's clear and thin and goes on fast and easy almost like water. It is also drippy so can be a little messy if you do not pay attention. It is pretty easy to clean up though,  wipes right off of tile and since it's clear, you do not really see it. It also covers great, so you only need about half as much sealer as finish paint. 

 

I would scrub it, seal it and paint it, then see what happens in the next few years.

If it's not soft, it is likely not being leaked on, but it may be, you'll know when the rainy season comes. If you paint it and it comes back, or if the roof is leaking onto it, you're probably going to have to tear it out and replace it anyway, and you will already have the paint...

I have used Dulux Weathershield Power+ primer in a very similar situation.

I wouldn't say it's non-drip, but it's very dense.

Covers stains very well.

Here are the pictures. They are now 700 pixels wide, rather than the original:

 

Above the window that has an extractor fan in it:

 

 

A close up of same:

 

 

Above the shower heater:

 

 

I then sprayed a little bit of bleach on a patch and gently rubbed it with kitchen paper:

 

 

It went white-ish. So I tried some hand soap with water on a sponge next to the bleached white spot:

 

 

Not as good as the bleach, but probably safer to preserve the paint.

So I reckon it is a kind of surface mould which comes off quite easily.

Looks like I need to get my step ladder out and a bowl of soapy water and a few cloths. ????

There are definitely no soft or wet spots. It feels quite hard and dry all over, but I'm sure Alexander Fleming would be interested in what I've got growing here.

 

Clearly I take showers in there, but the discolouration is everywhere - especially near the window with the extractor fan and above the shower unit. Everywhere, that is, except the edges of the ceiling which are still white - as if they've just been painted, but of course they haven't in at least 15 years.

I looked in HomePro Chalong (Phuket) but couldn't see any Dulux paint. And when I tried to describe "non-drip paint for ceiling" I could see they didn't understand. They only reacted positively when I said "Lazada", as if they would have some, which they don't.

I have bought it from Homepro, Pattaya and also Boonthavorn Pattaya.

Search for ICI Dulux gives just 1 result on Lazada - https://www.lazada.co.th/products/ici-dulux-powerplus-1-powerplus-1gl-multi-pp-primer-100-i1936824019-s6128926997.html?spm=a2o4m.searchlist.list.31.227a46b1ZaUv3Q&search=1

I had the same problem on a ceiling of a closed room after weeks of high humidity living on the coast in Phuket.

 

I sprayed the ceiling with a mixture of  50/50 vinegar (fermented) and water,  a square meter at a time, wiped it down, left it for 15 minutes then rinsed with clean  water.

 

Never had to paint it, never had a problem again though I did maintain  better ventilation.

 

Evidently bleach will not permanently kill mould on semi porous surfaces.
