What is the difference between interior wall paint and exterior wall paint?

Type of adhesive resin

The adhesive resin will determine the degree of adhesion of the paint to the surface. The exterior wall paint uses acrylic as the binding resin, which has extremely strong adhesion and provides maximum durability. But acrylic resin may have a pungent odor, so interior wall paint will stick to epoxy and silicone.

pigment

As mentioned earlier, pigments give your paint color. In order to avoid adding additional chemicals to the mixture, organic pigments are used in interior coatings. These have no pungent odor and are completely safe to breathe. But the durability required for exterior wall coatings is more important than protection from harsh chemicals, so you will find that the non-organic pigments in exterior wall coatings help aggravate strong odors and smoke, but they will not fade quickly.

 

 

Different Additives

Because interior paints don’t have to deal with as many potentially harmful situations, they don’t have many additives. But exterior paints need to handle all sorts of different weather, debris, temperatures, and more. To help with this, additional additives are used that can help the paint to resist fading, handle changing temperatures, and even prevent cracking.

 

Weather-Resistance

Interior paints are not expected to deal with harsh or changing weather conditions. Because of this, they have low temperature-resistance, low water-resistance, and they fade quickly in sunlight. But exterior paints are made to withstand all of these, so they have superior weather-resistance.

 

Durability

Exterior paint is built to withstand years of torment from the weather. It’s also made tough enough to not chip off from contact, such as twigs being thrown against your house by the wind or bugs flying into the wall. As such, it’s much more durable than interior paint. But interior paint is pretty durable as well; able to withstand occasional scrubbing and cleaning.
