The paint dries to the touch in a couple of hours, with full curing, meaning maximum durability and hardness, in about 7 days.
We use low-VOC paints and properly vent the space, so the odor is low to moderate and usually dissipates within a few hours to a day.
Duration depends on the project. For smaller areas, you can expect one to three days. For larger areas, three days to one week.
