Non durable paints for exteriors: I can explain whats wrong about using these kind of emulsions before applying in houses.
As the company and dealers give the confirmation about its long life rigidness on the walls but it does not work as they say all the time. they just spend lot of money on advertising and marketing. its works just like white wash that fade after some time. as it is costlier paint than the Nerolac paints which are of better use. so I recommend not to purchase such paints which are sold just to make money of water.
