The term One Coat Stucco refers to a blend of Portland cement, sand, fibers, special proprietary chemicals and water. One Coat Stucco combines the scratch and brown coat into a single application of 3/8″ to 1/2″ thick.

One Coat Stucco assemblies are code-approved proprietary systems that must be specified and installed per the manufacturer’s approved specifications and details. The information contained herein is to be considered for information only and does not supercede the manufacturer’s recommendations.

There are many reasons for the use of One Coat Stucco, which include:

  • One Coat application for reduced labor costs
  • Fiber reinforced which resists cracking and provides high flexural strength
  • Versatility of design and aesthetic appeal
  • Variety of finish styles and color
  • Water resistance
  • Performance in a variety of climates
  • Enduring of wet-dry and freeze/thaw cycles
  • Fire-resistive Properties
  • Low maintenance and life-cycle cost ratio
  • Speed of application
  • High abuse and impact resistance

Note: One Coat Stucco cannot achieve the finish tolerances achieved with traditional three-coat stucco due to the limitations on rodding the basecoat and the inability to staighten uneven substrates by the nature of its 3/8″ – 1/2″ thickness.
