The primary difference between interior and exterior paint lies in their formulations. Exterior paint is designed to withstand weathering, UV rays, and moisture, featuring additives that prevent mildew and fade resistance. It's tougher and more flexible to deal with outdoor conditions. On the other hand, interior paint is formulated to resist scrubbing, staining, and allow for easier cleaning, with additives to minimize odors and ensure a longer-lasting finish inside. Choosing the correct type of paint for your project ensures durability and the desired finish.
