A method for forming a sheet material suitable for use in manufacturing gliding board bases includes placing a first group of materials including plastic particles on a continuously moving surface in a first pattern, and placing a second group of materials including plastic particles on the continuously moving surface in a second pattern. Heat and pressure are applied to sinter the plastic particles together to form the sheet material having a first area with a first set of characteristics formed mainly of particles from the first group adjacent a second area with a second set of characteristics different from the first set of characteristics formed mainly from particles from the second group. The first and second sets of characteristics may include only one characteristic, such as color, hardness, wear-resistance, etc., or a plurality of different characteristics. A sheet material and gliding board having a base made with such sheet material also include first and second areas having at least one different property.
