A) Oil-based paints have been phased out of the market for architectural applicants. This is because of the need to have less solvent and less volatile organic compounds. The advantages of oil paints are that they give a smooth finish, resistance to moisture and durability. The disadvantages include the fact that they become brittle as they age and crack and peel, they develop mildew on exteriors and moisture-prone surfaces. Water-based also known as latex and acrylic paints can resist moisture, mildew, colour fastness and block resistance (the ability to avoid sticking to objects kept on the surface).
