Different Types of Paint

Requirement 2b: Explain the differences between oil-based paints, acrylic-based paints, and water-based paints.

Acrylic paint is fast-drying paint containing pigment suspension in acrylic polymer emulsion. Acrylic paints can be diluted with water, but become water-resistant when dry. Depending on how much the paint is diluted (with water) or modified with acrylic gels, media, or pastes, the finished acrylic painting can resemble a watercolor or an oil painting, or have its own unique characteristics not attainable with other media.

Water-based paints are made of pigments suspended in a water-soluble vehicle. Watercolors are usually transparent, and appear luminous because the pigments are laid down in a relatively pure form with few fillers obscuring the pigment colors.

Oil paint is a type of slow-drying paint that consists of particles of pigment suspended in a drying oil, commonly linseed oil. The viscosity of the paint may be modified by the addition of a solvent such as turpentine or white spirit, and varnish may be added to increase the glossiness of the dried oil paint film.
