the difference between different type of paints

Indoor / outdoor coating

There are only two types of paint, but using it for different projects inside and outside the house can still be a hassle. do not be afraid! There is a good way to simplify the whole problem.

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.

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.

Resistance to Physical Damage

If it takes a direct hit, your interior paint will likely chip off, exposing the old paint or bare wall beneath. Exterior paint can also be chipped, but it’s much harder because of how much stronger the resins bond the pigment to the surface.

Levels of VOCs

VOCs are volatile organic chemicals, and they release fumes that can be hazardous if you breathe them in. Luckily, interior paints are very low in VOCs, and often devoid of them entirely. But exterior paints are not. Since they’re not intended for use inside, exterior paints are often full of VOCs that will outgas into the open air outside. But if this happens inside, it could be a health risk.

Mildew Prevention

Interior paints do not generally have any mildewcides added. But on the outside of your home, algae, mold, and mildew are all real threats. To deal with them, mildewcides are added to exterior paints. These aren’t great to breathe in, but they’re very effective at stopping mold, mildew, and algae in their tracks.
