    Our MC-4021 Corners is 4-3/4" wide and 4-3/4" tall with a White Primer finish.

    uDecor accent features are manufactured with a dense architectural polyurethane compound (not Styrofoam) that allows it to be very durable and 100% waterproof. This material is delivered pre-primed for paint. It is installed with architectural adhesive and/or finish nails. It can also be finished with caulk, spackle and your choice of paint, just like wood or MDF. A major advantage of polyurethane is that it is safe to install in rooms with the presence of moisture like bathrooms and kitchens. This product will not encourage the growth of mold or mildew.

    They look good

    These corners were larger than the crownmolding that covers the length of the wall. So we used them for a different purpose in the room. We used the long crownmoldings for the corners as well following the Udecor youtube videos and it worked out pretty well.
