Surface bonding cements were introduced in the mid 1970's. They were designed as a component of a masonry wall system that eliminate the mortar joint in concrete masonry construction. Applied at 1/8" to both sides of the wall the result was a significant labor savings, and a stronger wall that was waterproof and semi-finished. Structural Skin when applied to both sides of CMU's will structurally bond the dry laid block eliminating the need for traditional mortar joints. Because eliminating the bed joint changes coursing it may be more efficient to lay the block in the bed joint but eliminate the head joints.
Maintaining existing concrete block, brick, stucco and concrete surfaces that are structurally sound but may need repair, repoint, or simply an updated appearance can be resurfaced. A value engineered solution is to apply a monolithic cementitious coating to protect the surface from further degradation and improve physical appearance. Structural Skin is a fiber reinforced surface bonding cement which can be applied directly to the substrate or in combination with metal lath to a thickness of 1/8" to 1/4". The new surface is waterproof and is engineered to last the life of the structure. Structural Skin, when applied to both sides of CMU's, will structurally bond the dry laid block eliminating the need for traditional mortar joints.
Structural Skin can be troweled or machine applied. Most carousel and rotor stator pumps are capable of spraying Structural Skin.
