Armawall Ultrafine top coat is a third step in the Armawall Texture Coating System with top coats that are designed to give excellent dirt shedding properties, substrate protection, and greater flexibility. Ultrafine is a durable exterior matt acrylic finish designed to give a cement render effect and bridge hairline cracks in masonry surfaces. Containing very fine silica, Ultrafine can be applied in various patterns and styles. It can left as a matt finish or it can be over coated with Armawall Armashield or Armawall Satin for extra durability and substrate protection. Armawall Ultrafine does not require primer except on Tilt Slab or CFC.
