Paint Techniques

Different types and grades of paint provide different application and resistance properties, depending upon the kinds and levels of ingredients used to create the paint. In turn, the properties of a paint determine the general quality of the coating.

Some of the many paint properties affected by the ingredients in the paint are:

Application and Appearance Properties	Interior Paint Properties	Exterior Paint Properties
Color	Stain Resistance	Color Retention
Hiding	Scrub Resistance	Mildew Resistance
Flow and Leveling	Lack of Yellowing	Blister Resistance
Level of Sheen Gloss	Resistance to Alkaline Clean	Dirt Resistance
Spattering Tendency	Burnish Resistance	Resistance to Peeling
Foaming Tendency	Block Resistance	Alkali Resistance

In general terms, all paints have four basic components which impact these properties. These components are:

What’s In Your Paint – Pigments

Provide color and hiding; some are used to impart bulk at relatively low cost

What’s In Your Paint – Binder

'Binds' the pigment together, and provides film integrity and adhesion

What’s In Your Paint – Liquid
Provides desired consistency and makes it possible to apply the pigment and binder to the surface being painted

What’s In Your Paint – Additives

Low-level ingredients that provide specific paint properties such as mildew resistance, defoaming and good flow and leveling
