Painting is a common activity that everyone does at home. Easy efforts to keep the look of the house looking new and fresh.
However, you may have been confused about the difference between interior Vs exterior paint. Or even assume that interior and exterior paint are the same.
Though the two are very different. It has its own formula for use on the wall surfaces of houses and different environments.
There is no good reason to use interior paint for outdoor walls or exterior paint in the room.

At worst, using exterior paint products indoors can be hazardous to health. At the very least, the resin in the exterior paint makes it less suitable for indoor surfaces.
On the other hand, interior paint when applied to outdoor surfaces will have a short lifespan. It is not made to withstand changes in temperature and UV rays.
In addition, because it contains a stiff resin, interior paint will crack and peel in very hot or cold weather.
Before discussing the difference between interior and exterior paint, it’s good to know the composition of the formula.
Paint can have any number of ingredients, but there are four components in each type. Namely solvents (water or oil), resins, additives, and pigments.
Interior Vs Exterior Paint Differences
So what’s the difference? Interior Vs exterior paint? Here’s the review.
Interior Paint
Interior paint formulated to resist scratches and stains and is easier to clean.
Uses a stiffer resin that won’t scuff or scratch easily and can be cleaned with soap and water.
Interior paints generally also contain fungicides and low Volatile Organic Compound (VOC).
This type of paint also has a variety of finishing. Ranging from color options to include matte, eggshell, satin, semi-gloss and gloss, as well as various types of faux-finish effects.
Exterior Paint
Exterior paint made with resins that are more flexible and can handle changes in temperature that can cause the paint to expand or shrink.
Additives in exterior paints are formulated to resist fading and mildew, and help paint adhere to rough surfaces.
Additives and resins in exterior paints contain and emit higher amounts of VOCs (volatile organic compounds) than interior paints.
Exterior paint offers fewer options for finishing. Usually only available in flat, semi-gloss, or gloss enamel.
Some exterior paints are oil based, though they are becoming increasingly rare.
Oil-based paints emit significantly higher levels of ozone-depleting VOCs than water-based paints.
