Is it safe to use outdoor paint inside?
Consequently, is it OK to use exterior paint inside?
Exterior paints should not be used inside as the mildecides used are not designed for interior use and can cause respiratory problems in some people. The higher volume of acrylics in the exterior paint could also be the cause of the lingering odor.
Similarly, it is asked, what is the difference between indoor and outdoor paint?
Different paints have different properties, and are formulated for different purposes. Interior paint is made to be scrubbed, resist staining, and allow cleaning. Exterior paints are made to combat against fading and mildew.
For regular paint, the smell could last for up to a month for poorly ventilated rooms. This is however on the extreme side with the average time for the smell to completely dissipate is about 14-24 weeks. To speed up the process, make sure that the room is well ventilated as the paint dries up.
