The Premium X board is made up by bonding a 0.8mm thick sheet of acrylic onto a double-faced white melamine board with MDF substrate. Finished thickness is 19mm. The color of the finished board is determined by the color of the Acrylic. The color range includes plain colors as well as metallic. The back of the board will always be white unless it is requested to finish both sides. The Premium X acrylics are durable and resistant to UV fading and water damage.
