Water-based paint

Water-based paint is a type of paint that uses water as the carrier liquid and is characterized by low environmental impact and non-toxic properties. Because water replaces organic solvents, these paints are considered safe for both applicators and users. Water-based paints stand out due to their ease of application, low odor, and fast drying time, and can be used on many surfaces including interior and exterior walls, wood, metal, plastic, and plaster.

Properties

• Carrier liquid: Water
• Low VOC content (volatile organic compounds)
• Odorless or very lightly scented
• Cleaning after application requires only water
• High color durability
• Presents no fire risk
• Easy to apply
• Environmentally and user-friendly

Application Surfaces

Water-based paints deliver high performance on porous surfaces and in interior spaces. Surfaces they can be applied to include:

• Plaster and stucco surfaces
• Concrete
• Brick
• Wood
• Previously painted surfaces
• Furniture surfaces (with primer applied)

Application Areas

• Interior and exterior walls
• Ceiling surfaces
• Wooden doors and frames
• Enclosed spaces such as schools, hospitals, homes, and offices

Application Techniques

Surface Preparation

• The surface must be dry, clean, and dust-free.
• If necessary, the surface should be filled and sanded.
• An appropriate primer should be applied before painting.

Application Method

• Can be applied using a roller, brush, or spray gun.
• Can be applied in one or two coats.
• Can be diluted with 5–10% water (according to product instructions).

Advantages

• Odorless and non-toxic to health
• Presents no fire risk
• Easy cleanup after application
• High color longevity
• Dries quickly
• Low risk of respiratory exposure

Limitations

• Adhesion may be weakened on excessively moist or highly glossy surfaces.
• Requires a special primer on oily or metal surfaces.
• Less durable than solvent-based paints under outdoor environmental conditions.
