We chose to make our platforms from plaster because it is naturally occurring, environmentally friendly, cost-efficient, and easy to install material. Since SeeLess mounts are intended for the drywall application, plaster mounts fuse monolithically with the drywall due to the commonality of the ingredients. Plaster does not expand and is not susceptible to temperature and moisture influences. It can also be painted to match the color of your home and blends in nicely.
