Emulsion vs. Paint: What's the Difference?
Edited by Aimie Carlson || By Harlon Moss || Published on December 9, 2023
Emulsion is a water-based mixture of polymers used mainly for walls and ceilings, whereas paint is a broad term for liquid substances applied to surfaces for color or protection.
Key Differences
Emulsion, typically water-based, is used for its quick-drying and low odor properties. Paint, in contrast, can be either water-based or oil-based, offering a wider range of finishes and uses.
Emulsion paints are known for their durability and washability, making them ideal for interior walls and ceilings. Traditional paints vary in durability and are used on diverse surfaces, including wood and metal.
Emulsions often provide a matte or low sheen finish, preferred for hiding imperfections on walls. While, paints come in various finishes, from matte to high gloss, suitable for different aesthetic and functional needs.
The composition of emulsion is such that it allows for more breathability of surfaces, reducing moisture problems. Paints, especially oil-based ones, can be less breathable but offer stronger waterproofing.
Emulsion typically has lower VOC (Volatile Organic Compounds) levels, making it more environmentally friendly. Paints, depending on their base, can have higher VOC levels, requiring more ventilation during application.

FAQs
Is emulsion only used for walls?
Primarily, but it can also be used on ceilings and other suitable surfaces.
Can paint be used outdoors?
Yes, certain paints are formulated specifically for outdoor use.
Can oil-based paint be used over water-based paint?
Generally, it's not recommended without proper surface preparation.
Is emulsion environmentally friendly?
Emulsions typically have lower VOC levels, making them more eco-friendly.
How to dispose of leftover paint?
Check local regulations for proper disposal or recycling options.
Does emulsion paint need a primer?
It depends on the surface; some surfaces may require priming first.
How long does paint take to dry?
Drying times vary, with water-based paints usually drying faster than oil-based.
Can emulsion be used in bathrooms?
Yes, specially formulated emulsions are available for high moisture areas.
Is emulsion suitable for wood surfaces?
It's not ideal; wood surfaces usually require specific types of paint.
Does paint color fade over time?
Some paints, especially in direct sunlight, can fade over time.
Is emulsion waterproof?
Not entirely, but it is more resistant to moisture than some paints.
Can emulsion be used on metal surfaces?
Generally, no. Metal surfaces require specially formulated paints.
Can paint be applied over wallpaper?
It's possible, but the results and durability can vary.
Do all paints contain lead?
No, lead in paint has been largely phased out due to health concerns.
Is emulsion paint washable?
Yes, many emulsion paints are designed to be washable.
Does emulsion emit a strong odor?
Emulsion generally has a lower odor compared to some oil-based paints.
Can paint be used as a primer?
Some paints have primer included, but a separate primer is often recommended for best results.
Can you mix different paint types?
Mixing different types of paint is generally not advisable.
How many coats of emulsion are needed?
Typically, two coats are recommended for even coverage.
