These days there are two options for paint surfaces - water based or oil based paint.
Most of the technology these days is all about making water based paints better and more durable, and the world is slowly phasing out oil based paints due to the harm they can cause the environment.
Water based paints are always best for ceilings, walls, weatherboards and even woodwork, like doors, door frames, windows and skirting boards. The technology on water based enamels is fantastic, and these products often have the hard wearing benefits of traditional oil based paints, with the added convenience of being quicker drying, having less odour, and being able to apply two coats in one day.
There are still situations where some people (particularly older traditional builders or painters), prefer to use oil based paint on doors, windows and trims as they believe it is the toughest, hardest wearing product of all. In exterior situations, it is very well known now that water based paints are much better because they can expand and contract in the harsh hot and cold weather extremes we experience in Australia.
