Do you ponder whether outside paint would be a wise choice for your bathroom’s excessive humidity? Or perhaps you have leftover outside paint that would be the ideal shade for your living room.

You shouldn’t apply outside paint inside the house in either circumstance.

Even after the paint has dried, the volatile organic compounds (VOCs) in outdoor paint are substantially harsher than those in interior paint. These VOCs emit a gas that is dangerous to breathe.

Additionally, exterior paint contains resins and mildewcide chemicals that make it dangerous to use indoors.
Further information is provided below.

INSIDE PAINT APPLICATION VS. EXTERIOR PAINT Although the four major components of paint—base, pigment, additives, and binder—are the same for all paints, the actual composition of interior versus exterior paint is very different.

Paint the interior

Today’s interior paint is primarily latex or acrylic with a water base. This paint is much thinner than exterior paint, but it has the ideal consistency for painting drywall.

Low or no VOCs are present in interior paint. Volatile organic compounds (VOCs) are solvents that assist in getting paint from the can to the wall.

VOCs release gas into the atmosphere as they dry. Interior paint generally poses no health risks because of its low VOC content.

In addition to having fewer chemicals, interior paint is more durable indoors than exterior paint. Compared to exterior choices, it resists furniture and everyday wear far better.

Paint the outside

VOC levels in exterior paint are substantially higher. This is why you can occasionally see home painters donning respirator masks, particularly if they’re applying paint with a sprayer.

Outside, the greater VOCs in exterior paint often don’t provide a health danger. But depending on the paint, it can continue to emit VOCs even after it has dried, which is a compelling argument against using it indoors.

Additionally, the ingredients used in interior and exterior paint are different. For instance, it contains additional resin, UV blockers, fungicides, and mildewcides.

The end result is paint that can bend in extremely hot or cold weather, tolerate extreme weather, and resist mildew. But due of the makeup, the chemical vapors might result in health issues including asthma, sinusitis, and more when applied to interiors.

CAN EXTERIOR PAINT BE USED IN THE BATHROOM?

It makes reasonable that bathroom paint would function similarly to outdoor paint. After all, it can survive rain and drastic temperature changes and is weather-resistant.
However, contrary to what might seem obvious, bathroom paint shouldn’t be exterior paint.

Exterior paint should not be used inside your home due to its chemical makeup, especially if you have family members who have weak immune systems or respiratory conditions.

Using interior latex paint with a satin or semigloss finish and moisture-resistant drywall is a preferable option for a bathroom.
CAN EXTERIOR PAINT BE USED IN THE GARAGE?

The garage is the finest place for interior latex paint. It won’t release hazardous chemicals into the air and will be more stain- and scratch-resistant.
Interior paint is always preferable even if your garage has good ventilation.
LAST THOUGHTS Although you might want to, you shouldn’t use exterior paint indoors. Interior paint has a very different recipe than outside paint.
It not only gives off harmful gases, but it also isn’t scratch-resistant.
Always use interior paint when painting interior walls.
