While you can technically use interior wall paint on doors, it's generally not recommended for long-term durability and performance.
Here's a breakdown of why:
-
Durability Differences: Interior wall paint is formulated primarily for walls, which experience less wear and tear. Doors, on the other hand, are high-touch surfaces that are constantly opened and closed, making them prone to scuffs, scratches, and dents. Interior wall paint is often less durable and less washable than paints designed for doors and trim.
-
Finish and Sheen: Wall paints often come in flatter sheens (like matte or eggshell) that hide imperfections. Doors benefit from higher sheens (like semi-gloss or gloss) because they offer better scrubbability and resistance to dirt and stains. Higher sheens are also more durable.
-
Adhesion Issues: Specialized door and trim paints often have better adhesion properties to withstand repeated contact and cleaning. Wall paints might not adhere as well to the smoother surfaces of doors, especially if they are previously painted with a different type of paint.
-
Long-Term Cost: Although using leftover wall paint on a door might seem economical initially, the increased likelihood of needing to repaint sooner due to wear and tear can actually make it a more expensive solution in the long run.
Why Specific Door and Trim Paints are Better:
- Formulated for Durability: Door and trim paints are designed to withstand daily use, cleaning, and impacts.
- Harder Finish: They create a harder, more resilient finish that resists scratches and scuffs.
- Easier to Clean: Higher sheen levels make them easier to wipe clean and maintain.
- Better Adhesion: They adhere better to various door materials, including wood and metal.
In conclusion, while using interior wall paint on doors might seem like a quick fix, it's best to invest in a dedicated door and trim paint for a more durable, long-lasting, and aesthetically pleasing result.
