Composition of Home Paints

Basic Components of Paints

1. Vehicle

Solvent/Thinner: Water in water-based paints, or organic solvents in oil-based paints.
Binder: The material that binds pigment particles together and adheres to the surface (such as acrylic, polyurethane, alkyd).

2. Pigments

Primary Pigments: Give the paint its basic color and coverage ability.
Secondary Pigments: Enhance certain properties such as UV resistance.

3. Additives

Anti-foaming agents: Prevent bubble formation during application.
Stabilizers: Improve stability and long-term storage.
Anti-freeze agents: Prevent freezing of water-based paints.
Driers: Speed up the drying process.
Anti-mold and fungus agents: Prevent mold growth.
Anti-settling agents: Prevent pigment settling.

Chemical Composition and Its Effect on Performance

Effect of Solid-to-Liquid Ratio

High solid ratio: Better coverage, greater durability, higher price.
Low solid ratio: Less coverage, ease of application, lower price.

Effect of Binder (Polymer) Type

Acrylic: Good flexibility, UV resistance, color stability.
Alkyd: High hardness, excellent gloss, but tends to yellow.
Polyurethane: Excellent chemical resistance, exceptional durability.
Epoxy: Corrosion and chemical resistance, high hardness.

Process of Selecting Appropriate Paints for Home

Determining Project Needs

1. Room and Usage Assessment

Traffic Level: High-traffic rooms require more durable paints.
Humidity Level: Humid rooms require moisture and mold-resistant paints.
Lighting: Low-light rooms benefit from light colors and reflective paints.
Function: Determining the primary use of the room to choose the appropriate type.

2. Surface Assessment

Material Type: Wood, gypsum, concrete, metal, plastic.
Surface Condition: New, previously painted, damaged, contaminated.
Surface Porosity: Determines the appropriate primer and paint.

Choosing the Right Color

1. Color Psychology and Its Effect on Mood

Warm Colors (red, orange, yellow): Create warm and intimate atmospheres.
Cool Colors (blue, green, purple): Evoke calm and relaxation.
Neutral Colors (white, gray, beige): Create a calm and elegant background.

2. Color Effect on Space Perception

Light Colors: Make spaces appear larger and brighter.
Dark Colors: Make spaces appear smaller and warmer.
Vibrant Colors: Attract attention and create focal points.

3. Testing Samples and Colors

Using Small Samples: Apply paint on a small area to test the color.
Viewing Color in Different Lighting Conditions: Daylight, evening, artificial lighting.
Using Color Palettes and Applications: Utilizing digital tools to visualize colors.

Calculating Required Quantity

1. Measuring the Area to be Painted

Walls: Length × Height (for each wall)
Ceilings: Length × Width
Subtracting Areas: Windows, doors, areas that won’t be painted

2. Calculating Paint Quantity

Coverage Rate: Varies by paint type (usually 10-12 square meters/liter)
Calculation Formula: Total Area ÷ Coverage Rate = Paint Quantity in Liters
Adding Margin: Adding 10-15% for emergencies and adjustments
