Olympic Panel Products’s most popular MDO is B-Matte™ 333, a one-sided overlaid panel with a veneer back. MDO is commonly used on jobs where a uniform matte finish is required. MDO is frequently used for high rise buildings of six to twelve stories, parking ramps, bridges, support columns, or other applications where a matte finish and multiple reuses are required. Contractors can expect 10-25 reuses from MDO depending on the application, proper handling, care and treatment with an appropriate release agent. HDO (high density overlay) has a resin content of 52 to
