Choosing the right type of paint—oil-based or latex (water-based)—is one of the first steps in any painting project. Each type has its own advantages and ideal uses, and understanding the difference will help you get the best results. Here are answers to the most common questions homeowners ask about oil vs. latex paint.
1. What is the main difference between oil and latex paint?
-
Oil-based paint: Uses natural or synthetic oils as a base. Known for durability and smooth finishes.
- Latex paint: Water-based, dries quickly, and is easier to clean up with soap and water.
2. Where should I use oil-based paint?
Oil-based paint is best for:
- Trim, doors, and cabinets (durable, smooth finish)
- High-traffic areas prone to wear and tear
- Surfaces where you want a glossy, hard finish
3. Where should I use latex paint?
Latex paint is best for:
- Walls and ceilings
- Exterior siding (acrylic latex resists weathering)
- Rooms where quick drying and low odour matter (like bedrooms or living rooms)
