Interior and Exterior Paints: What’s the Difference?
People often use the terms interior and exterior paints interchangeably, but this is not correct. Yes, they are both ultimately types of paints that serve the purpose of enhancing the health and appearance of your property, but they still differ in a lot of other aspects. Let’s review the main points of distinction between the two.
Understanding Paint
To be able to make a distinction between the different types of paint, we first need to learn some basics. Experts say there are four main elements in paint. These are:
Pigment: As the name suggests, pigment is the substance that gives paint its color. It can be derived from natural sources like plants, minerals, or animals, or can be artificially created.
Additives: We can customize the look of the paint by altering the consistency, texture, and finish. That is where additives come in. Additives help enhance the overall look and efficiency of a given paint.
Solvents: Solvents are substances used to dissolve and combine the paint ingredients into the liquid. After serving this purpose, they evaporate in the air as the paint dries. The most commonly used solvent is water.
Resins: Resins have a sticking property and are used to hold the pigments together in the paint. They also help in fixing the paint on the walls properly.
Distinguishing Between Interior and Exterior Paint?
The needs of your house’s interior and exterior are different. Therefore, the paints and products used for interior and exterior painting services are also different. Since the exterior of your house faces constant exposure to changing weather conditions, harsh UV rays, pollution, and more, it is more likely to sustain damage. To provide extra protection against this damage, professionals use paints containing more flexible resins and stronger additives for exterior painting. Exterior paints are also known for emitting higher amounts of VOCs or volatile organic compounds. On the contrary, interior paints contain more rigid resins and have very low levels of VOCs.
Another difference between the two is the number of color options available in each type of paint. While you can choose from a wide variety of colors for interior painting, you will seldom enjoy the same range of choices for exterior painting products.
