3. PRODUCT DESCRIPTION
ProSpec
®
Surface Bonding Cement CR is a versatile fiber-
reinforced, Portland cement-based product used to build and
restore retaining walls or block walls, patch large vertical holes
where non-sagging cement is a must, repair deteriorated
stucco, and in the construction of concrete block walls that are
dry stacked (without mortar) above the first course. Special
fibers control shrinkage, cracking, and sagging on vertical
applications and provides additional overall strength when
compared with conventional concrete.
Features and Benefits
• Portland cement-based
 Applications from ⅜ in. (9.5 mm) to ½ in. (13 mm) per layer
 Moisture resistant when mixed with ProSpec
®
Mighty Bond
 Glass fiber reinforced for durability
 High strength
 Controls shrinkage, cracking, and sagging on vertical repairs
Uses
• Interior or exterior
• Repair, strengthen, and decorate deteriorated concrete walls
 Patch deep vertical holes
 Restore damaged concrete, masonry, and stucco
 Bonds dry-stacked cement block walls
