Adorn your ceiling with High Density Polyurethane (HDP) decorative ceiling domes, surface mounted ceiling domes (page 20), and/or medallions. With hundreds of style to choose from, they provide for a great alternative to wood products. They are lightweight, will not crack, rot, or split and can be easily installed using standard woodworking tools. The product comes primed white and is paint grade only. Due to the water resistant properties of HDP, the possibility of mildew / mold growth and product staining is virtually inexistent. HDP has an overall core density similar to that of white pine, somewhere between 14 and 24 lbs.
