One Coat Stucco

One Coat Stucco is a proprietary, modified, traditional system. Introduced in the mid 1980’s The One coat stucco system base coat consists of a blend of Portland Cement, lime, fibers (sand) and proprietary chemicals. The individual products are pre-blended at the manufacturers facility which offers consistency and control of the material. The only materials that need to be added onsite are sand and water (although some One Coat Stucco come pre blended with Sand). Individual manufacturers have specific instructions for mixing and applying the basecoat that must be adhered to insure proper performance.

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 straighten uneven substrates by the nature of its 3/8″ – 1/2″ thickness.
