I recently had to ask a rep at Sherwin Williams about this as a home that was purchased a few months ago was painted with exterior latax paint. So although not ideal exterior paint could be used indoors but it is not reccomended. Here is the answer I received:
Hello,
The DURA WEATHER MAXBOND paint in the attic room would not be a health concern after 3 months as long as the attic room was ventilated after application to allow the volatile organic compounds the opportunity to escape into the atmosphere. If the attic room was not ventilated, you may experience acute symptoms from overexposure to the volatile organic compounds in the air. These acute symptoms would include headaches, nausea, and dizziness.
Often the same mildewcide which is used in interior paints is also used in exterior paints, but at a greater amount in exterior paints because mildew is more likely to grow outdoors in high humidity. The mildewcide that is used in the DURA WEATHER MAXBOND paint is commonly used in household plastic products like umbrellas and shower curtains, and it is used in many of our interior paints. It is an EPA approved broad spectrum fungicide which has been chosen because of its effectiveness against microorganisms and its low toxicity to mammals. This mildewcide is not volatile; consequently, it remains in the paint where it inhibits the growth of mildew on the surface of the paint.
As a rule we do not recommend the use of exterior paints for interior applications because exterior paints are formulated to chalk and regenerate the surface. In exterior paints the binder resins are softer and additional chemicals are not added to make the surface harder. Consequently, exterior paints do not possess the scrub resistance which is a desirable characteristic of interior paints. For this reason we do not recommend the use of exterior paints for interior applications.
