Best Answer

The only over-the-counter additive you could put into interior paint to make it more suitable for outside use is mildewcide. Interior paint doesn't really know that where it is going though. The reason a paint is classified as interior is because it is able to withstand cleaning. staining and scrubbing. Exterior paint, on the other hand, is formulated to withstand several freeze/thaw cycles and to hold up to UV rays, slowing the color fade.

Avoid fade prone colors and expect to repaint withing three to five years.

Can interior paint be used outdoors?

Yes, but it won't work as well as exterior paint. The difference may not be visible in the short run though. But interior paint formulations do not include such additive as moldicide/fungicide that help paint resist wet exterior conditions, or stronger elastomerics that help paint better expand and contract with the outside temperature fluctuations, or sun protectors and special pigments that resist fading. Outside paint also create stronger/more durable surface film for better surface protection.
