Hi Kathleen,
Thank you for reviewing Marquee Paint. I'm very sorry to hear that you had to buy an extra gallon because one coat wasn't enough. I completely understand how frustrating this must've been!
Marquee has a One-Coat Color Collection that guarantees full coverage in a single coat when applied to a previously coated surface. As it turns out, Ultra Pure White is not a one-coat color. I’m sorry if this information wasn’t provided during your purchase.
Please contact Behr directly, as we'd love to turn this situation around for you.
Kindest regards,
Doris
