Slide 7 of 41
Classifying Paints
Curing Mechanisms
• Solvent Evaporation – evaporation of solvent allows paint to dry
• Coalescence – particles of pigment and binder fuse together to bind the pigment
• Oxidation – binder oxidizes as it reacts with the oxygen in the air

Slide 8 of 41
Classifying Paints
Drying vs. Curing
• Drying occurs when solvent evaporates from coating
• Curing occurs when coating has reached optimum hardness

Finish Coats
Sheen, Cont’d…
Appearance
Higher sheens accentuate surface defects, textures,
and imperfections
Flat hides surface defects and is the most forgiving
sheen
Lower sheens soften the appearance of a room and makes walls look smooth
Durability
Higher sheens are generally more durable due to their
higher resin content
Lower sheens are not as durable but are easily
cleaned
Glossy finishes provide a smooth luster and are
excellent for trim, doors, and furniture
