Using exterior paint for interior spaces can cause issues. Exterior paint contains additives for weather resistance, which might release VOCs (volatile organic compounds) in enclosed spaces and can be harmful. Additionally, it generally lacks the smoother finish required for indoor aesthetics and may not adhere well to interior surfaces, leading to peeling and cracking. It's best to use paint specifically formulated for interiors to ensure safety and durability.
