What are the differences between water-based paint and oil-based paint?

Water-based paint uses clean water as its diluent. It offers excellent environmental performance, is harmless to human health, and has no pungent odor, allowing immediate occupancy after painting.

Oil-based paint is easy to produce, low in cost, with good application and penetration properties, and forms a flexible paint film. However, it has a strong irritating odor and generally takes about 2 months to volatilize until it is almost odorless.Water-based paint is generally used for residential interiors, as it not only provides a smoother finish but also has a longer service life and is environmentally friendly.

1.Different Irritating OdorsSince oil-based paint contains a large amount of volatile organic compounds (VOCs), it has a strong irritating smell. Staying in an area with a strong paint smell for a long time may cause adverse reactions such as chest tightness, breathing difficulties, and watery eyes.Only water vapor is released during the application of water-based paint. It features low odor and allows occupancy right after painting.

2.Different Feel of the Paint FilmOil-based paint delivers bright colors and good fullness, but a very clean construction environment is required to achieve a better gloss finish.Water-based paint mainly adopts thin coating, open, and semi-open construction methods, resulting in a smoother and finer touch.

3.Different Environmental PerformanceWater-based paint uses clean water as its diluent during construction, with low VOC content and generally no strong irritating odor.Most oil-based paints use thinners such as banana water, with VOC content more than twice as high as that of water-based paint.In terms of environmental performance, water-based paint is more eco-friendly than oil-based paint.

4.Different FlammabilityOil-based paint contains many flammable organic compounds and solvents, making it a highly flammable material. Fire prevention must be taken into account during transportation and construction.Water-based paint is non-flammable.

5.Different DurabilityAfter a period of use, oil-based paint tends to turn yellow, crack, or peel off.The durability of water-based paint varies by specific type. Due to the breathability and water permeability of its paint film, water-based paint may also turn yellow over time.
