A good paint should possess high spreading power and should be durable, tough and resistant to wear on drying. It should work smoothly and freely and should not crack, fade or change colour. Its surface should become dry in 9 hours and hard enough to take another coat in 24 hours. We should be able to spread it into a very thin layer and it should provide a smooth and pleasing appearance.
