Hi AmyTheArtist, thank you for your review. I'm sorry you did not get the expected coverage. Our i300 usually covers in 2 coats over an already primed surface, while darker colors and porous surfaces may require additional coats for full coverage. When applying multiple coats, we recommend waiting the recoat time of 2 hrs or more to avoid issues. Customer satisfaction is very important to us, and we want to help. Please feel free to reach out to us directly so we can assist you further. Our customer Care Team is ready to help!
