A: Hello Cocoo,
Thanks for writing in. Exterior coatings are not suitable for interior applications and should not be used. Interior coatings typically dry to a harder finish making them easier to withstand routine cleaning and scrubbing. While an exterior product is a strong coating, it is not made to resist this type of washing and can lead to early discoloration. I hope this helps and good luck with your project. Best, Roxana N.
