Interior Wall Paint (Coating) - Interior and Exterior Wall Coatings

Sichuan Chengdu/Yunnan Interior Wall Paint ~ Interior Wall Coating ~ Keshishi Interior & Exterior Wall Coatings [Paint Product Consultation - Manager Sun: 152_0825_6966] The differences between interior wall paint, interior wall coatings, and interior & exterior wall coatings are mainly reflected in their composition, performance, and applicable scenarios. Below is a detailed comparison:
1. Interior Wall Paint
Definition: Paint specifically designed for indoor walls, usually latex paint (water-based), with acrylic emulsion as the base material.
Features:
Environmental Friendliness: Low VOC (volatile organic compounds), non-toxic and odorless, suitable for enclosed spaces.
Weather Resistance: Only adapts to indoor temperature and humidity, not resistant to UV rays or rain.
Functionality: Easy to clean, mold-resistant (e.g., with added antibacterial agents), rich in color, diverse textures (matte, silk, etc.).
Application: No need for strong weather resistance, simple base layer treatment.
Applicable Scenarios: Bedrooms, living rooms, and other dry indoor environments; not suitable for outdoor or high-humidity areas (e.g., bathrooms).

2. Interior Wall Coatings
Definition: A broad concept covering all indoor wall decoration materials, including paint and non-paint types (e.g., diatom mud, artistic coatings).
Features:
Diversity:
Paint Types: Such as latex paint, with performance similar to interior wall paint.
Non-Paint Types: Diatom mud (adsorbs formaldehyde, regulates humidity but not scrub-resistant), artistic coatings (3D textures, higher cost).
Environmental and Functional Aspects: Some products emphasize special features (e.g., odor elimination, formaldehyde adsorption), but material limitations should be noted.
Applicable Scenarios: Choose based on needs, e.g., diatom mud for children's rooms, artistic coatings for accent walls.

3. Interior & Exterior Wall Coatings
Definition: Coatings suitable for both indoor and outdoor use, mostly solvent-based or high-performance latex paints.
Features:
Weather Resistance: Resistant to UV rays, temperature differences (-30°C to 50°C), and rain/snow erosion.
Adhesion: Stronger than interior wall paint, adaptable to various substrates like concrete and metal.
Environmental Friendliness: Outdoor types may contain more additives and slightly higher VOC; indoor-approved models must be selected.
Application: Requires a solid base layer and may need primer for enhanced bonding.
Applicable Scenarios: Building exteriors, balconies, etc., but ensure environmental standards are met before indoor use.
