This Activa smart interior paint seems to be a perfect paint for many reasons. It is self-cleaning, antimicrobial, low odor. It takes some elbow grease to use it though. After adding the cup of water, the mixing was very tedious. It was like mixing grout. It probably needed an power tool with a paddle. After giving up on mixing, scooped some out with the mixing stick into the tray. Using a roller, the paint rolled out clumpy like in the can, but going over it with the roller for a couple of extra strokes, it flattened out and looked good.
