Choosing the right paint type is one of the most important steps in achieving a durable, beautiful finish. The two main options—latex (water-based) and oil-based paints—offer different advantages depending on your project. Understanding their differences will help you select the best product for your surfaces, environment, and long-term maintenance goals.
What is latex paint?
Latex paint, also known as water-based paint, is made using water as the primary solvent. It’s popular for its easy cleanup, quick drying time, and low odour, making it ideal for most residential interiors and exteriors.
Key benefits of latex paint:
- Dries quickly (within hours)
- Easy to clean up with soap and water
- Low odour and VOC emissions
- Flexible and less prone to cracking over time
- Resists yellowing and fading
Latex paints from Randall’s Paint Collectionsare available in a range of sheens and finishes for both walls and trim, offering excellent coverage and colour retention.
What is oil-based paint?
Oil-based paint uses natural oils (like linseed) or synthetic alkyds as its base. It’s known for its smooth, durable finish and strong adhesion, making it an excellent choice for high-traffic or high-moisture areas.
Key benefits of oil-based paint:
- Extremely durable and resistant to wear
- Creates a smooth, hard finish ideal for trim, doors, and cabinetry
- Excellent for sealing stains and blocking moisture
- Provides superior coverage on rough or aged surfaces
However, oil-based paints have a stronger odour, take longer to dry, and require mineral spirits or turpentine for cleanup.
How can I tell which paint type I currently have on my walls?
If you’re repainting, it’s important to know whether your old paint is latex or oil-based before applying a new coat. Here’s an easy test:
- Soak a cloth in rubbing alcohol or acetone.
- Rub it over a small area of the painted surface.
- If the paint softens or comes off, it’s latex paint.
- If it doesn’t, it’s likely oil-based.
If you’re switching from oil to latex, be sure to sand and prime the surface first to ensure proper adhesion.
Where should you use latex paint?
Latex paint is perfect for most interior walls, ceilings, and exteriors where flexibility, low odour, and easy maintenance are priorities. It performs well in:
- Bedrooms and living areas
- Hallways and dining rooms
- Exterior siding, stucco, or brick
- Ceilings and low-traffic surfaces
Where should you use oil-based paint?
Oil-based paint works best on surfaces that need extra durability or a glossy, smooth finish, such as:
- Baseboards and crown moulding
- Interior and exterior doors
- Cabinets and trim
- Furniture and metal surfaces
Can latex and oil-based paints be mixed or applied over one another?
You should never mix latex and oil-based paints directly. However, you can apply one over the other if the surface is properly prepared:
- Applying latex over oil-based paint requires light sanding and a bonding primer.
- Applying oil-based over latex paint requires a clean, lightly sanded surface for adhesion.
For best results, use compatible primers and paints from trusted brands available at Randall’s Paint Collections
Which paint type is more eco-friendly?
Latex paint is the more environmentally friendly option. It has lower volatile organic compounds (VOCs), less odour, and simpler cleanup—making it safer for both your home and the planet.
What about drying and recoating times?
-
Latex paint: Touch dry in 1–2 hours, ready for a second coat in 3–4 hours.
- Oil-based paint: Takes 6–8 hours to dry and up to 24 hours before recoating.
When painting large projects or working with limited ventilation, latex paint offers a faster, more convenient workflow.
