Plaster of Paris or POP is a quick plaster that is mixed with water to create a design as needed and left to dry. It is a short-lived atomizer in the world of home decor. Although it is primarily used to design false ceilings in bedrooms, it can be used for a number of design options: wall design pieces, feature walls, or unique detail panels. But you should use the services of design and decoration professionals if you intend to use POP on a large scale in your home.
