Opti-Rite® dry erase wall coverings and flexible dry erase materials for the professional installer. These materials require an adhesive for installation. Unlike our peel and stick, self-adhesive dry erase Opti-Rite® materials, these high quality dry erase wall coverings need an adhesive for installation. These Opti-Rite® brands may require an adhesive but they offer a few options that our current line of Opti-Rite® Peel and Stick brands don't. Opti-Rite® Mag™ has a light magnetic receptive dry erase surface. The magnetism is strong enough for light magnetic accessories but not as strong as a porcelain steel whiteboard. Opti-Rite® One is a heavy duty, bright white dry erase wall covering with a cloth backing. Compare Opti-Rite® 1 to Marsh Poly-Rite 1 or Walltalkers Just-Rite. Opti-Rite® Matte™ offers a more muted or less glossy finish which allows you to use the materials not only as a dry erase surface but also as a projection medium as wellOpti-Rite® Grid™ comes both magnetic receptive and regular and has a light ghost image which is approximately 2"" x 2"". All of these Opti-Rite® materials require an adhesive for installation. For the best results and to make removing your Opti-Rite® materials easier when the time comes the wall or surface should be primed with an acrylic primer. For the best results we also suggest that you hire a professional installer who is familiar with installing a heavy weight vinyl wall covering material.
