Abstract
A method of coating a component part (10) with a protective coating having a rough surface appearance in which the surface is covered with a first layer (L1) of powder coating, a particulate material (26) is spread over the first layer (L1) whilst the layer is tacky, and a second layer (L2) of powder coating is applied over the particulate material (26) and first layer and caused to coalesce. The method is particularly suitable for coating roofing materials to give the appearance of slate, stone, terra-cotta.
Claims10
A method of manufacture of sheet building components having the appearance of a mineral, stone or ceramic material in which method the component is coated with a protective coating having a rough surface appearance caused by particulate material within the coating, said method comprising the steps of:
- applying a first layer of powder coating to the component, heating the component with the powder coating thereon to form a soft first layer, spreading particulate material onto said first layer while said first layer is in soft a condition, applying a second layer of powder coating over the particulate material and first layer, and causing the second layer of powder coating to coalesce.
A sheet building component which is decorated to give the appearance of a mineral, stone, or ceramic material with at least a portion of a surface of said component having a varied surface pattern of raised and depressed portions and being coated by layers of polymeric material having particlate material embedded therein, said poylmeric material layers comprising a first layer of powder coated polymeric material having the particulate material scattered thereon, and a second layer of powder coated polymeric material coating both the first layer and the particulate material all said layers being of substantially uniform thickness on the raised and depressed portions.
