Oil Based Paint vs Water Based Paint for Interior House Painting
If you are planning to paint your interior walls, you might be wondering whether to use oil based paint or water based paint. Both types of paint have their advantages and disadvantages, depending on your needs and preferences. In this blog post, we will compare the main features of oil based paint and water based paint, and help you decide which one is best for your project.
What is Oil Based Paint?
Oil based paint is a type of paint that uses a solvent, such as mineral spirits or turpentine, to dissolve the pigment and binder. Oil based paint dries by evaporation of the solvent and oxidation of the oil, forming a hard and glossy film. Oil based paint is more durable and resistant to stains, scratches, and moisture than water based paint. It also has better adhesion and leveling properties, meaning it can cover imperfections and create a smooth finish. Oil based paint is ideal for surfaces that need more protection and shine, such as trim, doors, cabinets, and furniture.
What is Water Based Paint?
Water based paint is a type of paint that uses water as the main solvent to dissolve the pigment and binder. Water based paint dries by evaporation of the water, forming a flexible and matte film. Water based paint is more eco-friendly and safer than oil based paint, as it emits fewer volatile organic compounds (VOCs) and has less odor. It also dries faster and cleans up easier than oil based paint. Water based paint is ideal for surfaces that need less durability and gloss, such as walls, ceilings, and drywall.
How to Choose Between Oil Based Paint and Water Based Paint?
When choosing between oil based paint and water based paint for interior house painting, there are several factors to consider:
- The current type of paint on the surface: If you are repainting an existing surface, you need to know what type of paint was used before. You can test this by wiping the surface with denatured alcohol. If the rag picks up the paint, it is water based. If no paint rubs off on the rag, it is oil based. You should never apply water based paint over oil based paint without proper preparation, as it will not bond well and will peel off or crack. You can apply oil based paint over water based paint, but you need to sand and prime the surface first.
- The level of durability you need: If you are painting a surface that will be exposed to frequent contact, abrasion, or moisture, such as trim, doors, cabinets, or furniture, you should use oil based paint for more durability and protection. If you are painting a surface that will not be subjected to much wear and tear, such as walls or ceilings, you can use water based paint for more flexibility and breathability.
- The frequency of repainting: If you are painting a surface that you plan to change the color of often, such as walls or ceilings, you should use water based paint for easier application and removal. If you are painting a surface that you want to keep the same color for a long time, such as trim or furniture, you should use oil based paint for longer lasting results.
- The desired sheen level: If you are painting a surface that you want to have a glossy or shiny finish, such as trim or furniture, you should use oil based paint for higher sheen levels. If you are painting a surface that you want to have a matte or flat finish, such as walls or ceilings, you should use water based paint for lower sheen levels.
Oil based paint and water based paint have different characteristics that make them suitable for different purposes. Oil based paint is more durable, resistant, glossy, and adherent than water based paint. Water based paint is more eco-friendly, safe, fast-drying, easy-cleaning, matte, and flexible than oil based paint. Depending on your needs and preferences, you can choose the right type of paint for your interior house painting project.
