The two main types of house paint are:

1. Interior paint: This is paint that is designed specifically for interior use and is commonly used on walls, ceilings, and trim. Interior paint can come in a variety of finishes, including flat, eggshell, satin, semi-gloss, and high-gloss.
2. Exterior paint: This is paint that is designed specifically for exterior use and is commonly used on the exterior walls, trim, and other outdoor surfaces of a house. Exterior paint is typically more durable than interior paint and is formulated to withstand weather and environmental conditions. It can also come in a variety of finishes, including flat, satin, semi-gloss, and high-gloss.
