External walls have to be bear many things like bad weather, stormy winds, temperature variations, etc., So they have to be very tough, impenetrable.

So the paint to be applied on that should help the wall do so.

For exterior walls paints must have these properties…..

1. UV resistance
2. Water resistancE
3. Dirt pickup resistance
4. Thermal insulation
5. Anti algae & anti fungal property
6. Wet scrub resistance

Apart from these many other properties like good sheen, highly elongation, etc must be in high extent in the paint for best performance.

Paints good to be applied on the outer walls are

• Latex based
• satin and eggshell

Now the brands

In the current scenario, given the R & D development most companies like Asian paints, Berger, Nerolac have similar quality paint. Slightly ahead would be Dulux.

The most important thing is not the paint but the painter

In the case of Exterior Paints Dulux Weathershield, Nerolac Excel, Asian Paints Ultima Protek, and Apex Ultima pitch in. It is good to choose products that suit your requirements rather than brands while choosing paints for interiors and exteriors of houses.
