What is the best brand for problematic roof
I saw China product... But not sure
Nippon although very famous, I don't think they are good specifically for roof issue. Most are acrylic baswd

I'm looking for certain criteria
Can reflect sunray
Allow water to flow nicely like flow on the mirroe
Long lasting

Mapei

Best is jangan cat

best is change roof tiles lol i use jotun. so far its ok. but still its water based xD

China brand ?
No thanks

Go for sika

Put solar panel,
Solve ur heat n tnb bill .

look quite promising

Serious .. I hv spoken to a lot of painters and their advise is dont paint the roof ..

replacing is too expensive lor

Don't paint. No joke. Bad experience after painting will hit you probably after 1.5-2 years.

sika

i use 25 litres of sika 500...

so far no leak yet. on its 3rd year running.

thats what i am looking at. but dunno what brand.

can i use pu paint polytrehtrane 1 layer, then another layer of nippon?

its arcylic based...i thought arcylic short term one?

use sikacoat as primer, then use other brand paint topcoat, possible?

Can share your Surface area applied?

concrete flat roof..

total about 1200 sq feet

u need a sealer + 2 coat nippon PU
without proper base, your paint will be flaking

Whats their reason?

I've experimented with Chinese products for roofing, but honestly, they're not worth the hassle. The guys at southport roofer near me suggested focusing on reliable brands like Nippon, which are renowned for their quality and durability.

The one with Dato LCY face on it ads

this one looks like suitable..comes with fibre too.,. anyone tried?

If root tiles, better don't paint. Roofers say very difficult to pinpoint leak after pain.

If flat roof concrete, ok to paint.

Can use sikaflex to seal pond fountain which constantly flowing water ?

Hi,I am planning to paint..Do I need to apply primer

How big is your house roof?
25 litres is enough?

obviously yes. primer act like an adherent, ensure that paint stick to the wall. without primer, the paint just touch so so to the wall, it never attacht to it

if done correctly, maybe can last 5 years and won't clot the roof tiles rain water grout.
End of the day, once the paint start to peel or lose the colour, it look much worse than before.

If done wrongly, leaking everywhere and there is no other solutions except need replace the whole tiles





Do remember all the original roof tiles colour are baked to withstand our crazy weather.
Do you think just cleaning and paint over like that will last longer than you think

ooh. but then why paint companies sell roof paints?

Ahhh... so means use the Sika 500 then only apply another layer of paint on top. Correct ar?
