@amduser - does it make sense to use a cheaper line of paints for ceilings?

Yes this is common practice. But I still use good ones. As it's within my budget.

Yes, very normal since we don't usually touch the ceiling and we rarely clean it so even cheap paint can last got a long time provide that you prepare the surface properly before painting

Finally got it painted with Pentalite since I don't deal with chalking in the future, the pollution from the haze is bad enough as it is. However I was told that the cheaper maxilite was better for plaster ceilings as a first coat without a primer to avoid bubbling and peeling which happened to my ceilings.

Are parquet floors over here normally finished with shellac or urethane/varnish?
I think the floor I'm looking at is shellac because a few spots which have been touched accidently with glue or cleaning alcohol has bubbled and turned yellowish.

there are few causes for peeling, some common one is dirty ceiling or leaking ceiling

parquet floor usually is varnish, the floor in my hometown use that and it last for more than 10 years already, but still depends on your usage i guess

i'm not so sure about floor coating though, newer laminate floor dont even need painting, epoxy PU usually for bathroom, yard, car porch and balcony

No the ceiling is fine, the problem is bubbling/peeling after painting.

Guy, have a question on external paint. Between Jotun and Nippon which is more suitable for seaside housing? & how to scrap off old paint with black spot (any particular chemical to use?)

Currently looking at these:-


Topcoat
1. Jotashield Colour Extreme

2. Jotashield AntiFade Colours


Primer
1. Jotun Ultra Primer

2. Jotashield Primer

3. Cito Primer 09

Mind to share what the current market average price for above paint in 20L??

Thanks.

Want to seek advice. I'd had leaking and termite issues previously which had damaged some of my internal paint. Its sorted now, and after a very long time finally decided to fix repaint walls and replace skirting to pvc.
Question, the leak had quite a damage as per pctures. It flake the paint and i had scrap whichever portion i managed to. Evwn the undercoat or sealer was also easily scrap out which leaves a thick layer between the ok portion and bad portion.
I will later try to sand the area between the ok and bad ones to leave as smooth as possible finish between those.
Question, to fill the gap between the ok part and bad part, what is best material? I experimented putty fill (liquid type) but its hard as it cant coat thick layer. Would a normal paste putty filler does the job or there are better options?
And assuming if i manage to fill with putty and sand it to level, would i need primer or sealer on the repair part? Iplan repaint the whole wall, would there be visible mark on the repaired portion?

I know this is an old post but just want to share my experience for those considering Jotashield. Late last year (around December), I repainted my house with Jotashield Colour Extreme. Over 13 years ago I had used Jotun Jotashield as well and was satisfied with it.

Thinking that Colour Extreme was an upgrade since it came with 12 years warranty, I was silly enough to spend extra money to buy and use it.

Two months later my exterior walls of my house was covered with water streaking marks. Complained to Jotun and they had the cheek to tell me to use soap and clean the walls. WTF.

After several complaints and follow-ups, they finally agreed to replace the paint with Jotashield Anti-Fade, which supposedly comes with anti-watermark technology (which surprisingly the more expensive Colour Extreme did not have). So now, I have to pay someone to repaint my house again and hope that the water marks don't come back.

In my opinion, Jotun shouldn't have put Colour Extreme in the market as it is so prone to water marks. As Malaysia is a temperate country with a lot of rainfall, the black water marks can appear very quickly, and looks very obvious especially if you are using a light coloured paint.

I hope Anti-Fade is better. Will update this thread 6 months down the road. I don't know why Jotun changed their Jotashield paint formula. The Jotashield I used 13 years ago had zero issues.

Use cement without mixing with sand.

Spray some water on the affected area b4 plastering. Just to make it wet for better plastering adhesion.

After plastering, use a palm sized wet sponge to lightly remove uneven/extra thickness. Dont use sand paper as it wont gives a smooth finishing.

Once dry, paint. Dont need sealer for the plastered area. Use your normal paint over the plastered area a few times first after each coat dry and then finished with the whole wall.

Filler dont work for large area like yours.

Buy normal cement and not those cement glue for tiles....1kg RM1 for loose packing.

This is actually depends on the formulation of the paint, nowadays a lot of paints have gone for the development of Low VOC and elastomeric route, which the formulation actually results in lower dirt pick-up resistance. But on the other hand, it solves other common problems in our humid weather such as efflorescence. There really isn't any perfect formulation yet in the market, it really depends on how the paint manufacturer take the balance between these properties. There is not much we can do with the choices in the market except to look for hydrophobic coating to protect the paint films. In my opinion I would rather use the most common exterior product (Jotashield in your case) and do regular maintenance for decorative purpose.

Thanks for the advice. The cement to water portion use 1 cement :0.5 water ? In event i didnt do a good job on plastering the cement, can the cement be sanded via sanding machine probably with mid grit paper? Since i not very confident on my plastering skill with cement

I wont know the ratio as i dont measure it when i use. As long is paste form, then is should be ok. Add little water at a time. Initially it will be lumpy. Once sufficient water, it becomes paste form. If you have added too much water, just add some cement. So play around cement with water.

Yes you can sand it using machine and grit paper but it will be dusty. Wear mask. Using sponge is better as your palm can feel the evenness of the plaster with the other area.

Mind to share the photo of the water streaking mark?

I did use the same Jotunshield Extreme and painted my front perimeter wall during the same period of time like yours, up until now still clean and without any black water mark. What I did was apply a primer first before applying the Extreme coat (both is in pure white colour). And my location is just beside the sea.

Then my neighbour that use the Jotunshield Anti-fade which only lasted for 6 month and the colour started to faded, I suspect the paint issue is due to the workmanship of the painter and also the timing of the painting. Cause rain came pouring 1 or 2 day right after the paint job completed.

I will try to post a photo of the actual wall later but it looks something like this.

water marks from rain

At first, I thought it may have been workmanship problem or maybe that particular paint I used had problem, so I bought a smaller 1 liter tin of the same paint (Colour Extreme), and paint it again myself on one wall to see if it made a difference. Two to three months later, same issue recurred on the wall I painted. Both times, Jotashield Primer was used first, and the surface was properly prepped.

The area I live at is rather hilly, and has some amount of rain almost every day, so maybe that was the issue. It just couldn't deal with excessive rainy weather, resulting in the water marks.

When I filed my complaint with Jotun, they sent someone over to inspect. After checking, he said it was not incorrectly painted and also, it wasn't a primer / surface prep issue. I was told that apparently, this problem is not uncommon (WTF?), and after consulting his technical team, I was advised to wash my walls with soap and a pressure cleaner (which by the way, doesn't work). Also, not sure how Jotun was expecting house owners to be "cleaning" the entire exterior of the house every 2-3 months. Also, I pointed out that my neighbors which uses the same Jotun paint (not Colour Extreme) and in the same colour, does not suffer from the same issue. In fact, before I repainted my house, there weren't any water marks on it either.

The person from Jotun then suggested I use Anti-Fade which has anti-water mark technology. I was a bit flabbergasted because I thought Colour Extreme being the more expensive paint would be the same, if not better, in this respect.

Long story short, after several complaints, they replaced the paint for me with Anti-Fade so hopefully it works better for me. Will report in 6 months with my observations.

I think there is some form of condesation on your wall as well.
You will need to solve that problem first before patching it up, cuz the condensation will come back again and you will have to re-do again and again..endless.

He got mention he sorted it already

Yup, the water seeping is sorted as i did foam injection and t200 on outer layer a while back. Speaking of patching the wall, i went to those local hw shop, they advised to use stopping compound vs cement as it will be easier and smoother, i bought both to test on different areas see which will be easier to work with.

On a side note i havt started though coz i have another problem to solve before working on this, have yet to sand it as well. Figuring a way to airtight my wardrobe sliding doors so no dust can go in when i do sanding.

So i patched my wall using stopping compound as cement is a bit hard to work with, actually both also hard to work with, stopping compound in my bucket dries and hardened before i complete.
Now that i patched, put on a layer of undercoat paint, only to noticed there is hollow sound when knock on patch area, is this normal? It happends to the bigger patch area the hollownsound is like a very hard layer not sticking, the smallet one near the window doesn't have a less audible hollow sound.
Is this normal for a patched wall, or i need redo the patching? Before i eventually paint it
