Yes, interior primer can be used with exterior paint in certain situations, but it's not generally recommended. Interior primers are formulated to work within the controlled environments of indoor spaces, lacking the necessary additives that protect against weather-related wear. For optimal results and durability, choose a primer specifically designed for exterior use. This ensures that your painted surfaces are better protected against moisture, temperature fluctuations, and UV rays.
