Which is better for walls: water-based or oil-based paint?
June 3, 2021
What are Water-based paints?
Water-based paint is similar to oil-based paint in that it uses water instead of oil. This signifies that in this form of paint, the water is evaporating.
Water-based paints contain a pigment and a binder, as well as water as a carrier. They are the most popular and ecologically friendly paint choice. They have better colour retention over time, dry faster, and have less scents than alternatives. Finally, water-based paints may often be applied over existing oil-based paints, but not the other way around.
What are Oil-based paints?
Oil-based paint, as the name implies, contains oil, either synthetic or natural. While the paint dries, the oil is the real element that evaporates.
Oil-based paints are exceptionally long-lasting and can survive repeated contact, making them perfect for moldings and trimmings. This approach also resists stains and rust over time since the resin in an oil-based paint develops a hard, non-breathable layer. Keep in mind that oil-based paints have a stronger odor and take longer to dry than water-based paints. They’re also more difficult to clean.
Advantages of Water-based Paints & Oil-based Paints
Water-based paint does not have a lustrous finish. A level finish may need numerous coats of paint. The matte surface, on the other hand, effectively conceals flaws. Oil paint has a high sheen. Oil-based paint, sometimes known as “high gloss,” does not disguise flaws very well.
Oil-based paints often dry faster, providing greater resilience to wear and strain. However, when the paint dries harder, it loses flexibility, making oil-based paints more prone to cracking, drying out, brittleness, and chalkiness over time. Oil-based paints have a reputation for yellowing with time. There have been several advancements in recent years that allow water-based paints to dry fairly hard and resist damage and wear and tear. Water-based paints’ elasticity allows them to expand and contract in response to changing weather conditions, making them less prone to cracking.
Time to dry
For water-based paints, 4-6 hours of drying time is generally sufficient. Water-based paint dries significantly more quickly than oil-based paint. It may take 6-8 hours for the paint to dry to the touch, and you may need to wait up to 24 hours before applying a second layer.
External wall Solutions
Exterior applications benefit greatly from water-based paints. This is due to the fact that water-based paints are far more resistant to UV radiation, allowing them to keep their shine and colour for longer lengths of time. Because of the paint’s flexibility, it can move with the substrate as it expands and contracts under varied weather conditions, making it ideal for external applications. Oil-based paint does not work well outdoors since it degrades in the sun and forms a powdery surface. Because the paint has little to no flexibility, it cannot expand and contract with the substrate under different weather conditions, increasing the likelihood of breaking.
Water-based paint is simple to clean up with soap and water. Cleaning off oil-based paint will necessitate the use of harsh chemicals such as Mineral Spirits.
Volatile Organic Compounds (VOCs) are substantially lower in water-based paint. People with sensitive sinuses should avoid it. Oil-based paint contains far more volatile organic compounds (VOCs), resulting in harsh chemical-like scents that need much more ventilation.
Finally, water-based paints release far fewer fumes and are better suited for interior application. Although Oil Based Paint is still often used as an accent where a glossy finish is desired, most people prefer the matte texture of flat paint since it hides flaws better.
