Remove all items from the bathroom (towels, bathrobes, personal care products) into a closet and vacuum thoroughly the walls, ceiling, shelves and other places where the dust could be. This will help to avoid dust getting into the coating. Close the window so that insects would not fall on the coating as well. Prevent animals from entering into bathroom during work and after, while the material is getting dry. Maintain the temperature in the bathroom no less then + 22ºС for one day before the work, at the time of the work, and within 2 days after applying the material.
