DESCRIPTION: BVS VERTI-PATCH is a polymer modified, non-sag, two component, fast setting cementitious gel mortar. BVS VERTI-PATCH is formulated specifically for trowel applications on vertical and overhead surfaces.

• Filling form tie holes, honeycombs and other voids in concrete and masonry
• Patching concrete and masonry on vertical and over head surfaces, interior and exterior, above and below grade
• Structurally repairing concrete on parking facilities, ramps, bridges, tunnels and balconies

• High early compressive, tensile and flexural strengths
• Very low shrinkage
• Compatible with the thermal movement of concrete
• Excellent freeze/thaw/resistance
• Excellent bond strength
• Increased abrasion resistance
• Resistant to dilute acids and mild chemicals
• Fast-setting and self-curing
• Pre-proportioned units to insure consistency and facilitate mixing

BVS VERTI-PATCH is supplied in 50 lb. Pails

BVS POLY-BINDER is supplied in 1-gallon containers

COLOR: When mixed, BVS VERTI-PATCH is concrete gray

YIELD: BVS VERTI-PATCH will yield approximately 0.5 ft. per unit

STORAGE CONDITIONS: Both components of BVS VERTI-PATCH must be stored at or above 45ºF (7ºC) in a dry area. Avoid high humidity and temperatures above 95ºF (35ºC). The shelf life is one year in the original unopened containers.

SURFACE PREPARATION: The existing concrete must be clean and sound. For patching applications, saw cut a vertical edge of at least 1/8 inch around the perimeter with a masonry saw. Remove all laitance, grease, dust, curing compounds, bond inhibiting materials, spalled and unsound concrete from the patch area. If rein- forcing steel is exposed, follow ACI standards. All rust must be removed and rebar primed. If reinforcing steel must be replaced, follow ACI standards for the removal and installation of reinforcing steel. For patching above the first elevation, it is recommended that steel pins be secured in the parent concrete. This will insure the integrity of the patch.

PRIMING: The use of a primer is usually not necessary. However, when porous concrete is encountered, the use of slurry coat is recommended. This use of a slurry coat (one part latex, two parts powder) should be thoroughly brushed into the substrate. Once the slurry coat becomes tacky, BVS VERTI-PATCH can be applied.

MIXING: BVS VERTI-PATCH may be mixed by manual or mechanical means. Manually mix in a pail, wheelbarrow or mortar box. Mechanically mix using a heavy-duty, slow speed drill with a mixing paddle or mix using a mortar mixer. By either means, add 1 gallon of BVS POLY-BINDER into a mixing compound. Add BVS VERTI-PATCH while continuing to mix. Mix to a uniform consistency. Depending on the consistency desired, 8 ounces of additional water may be added. Mix for no more than 5 minutes.

WORKING TIME: BVS VERTI-PATCH has a working time of 10-15 minutes at 70ºF (21ºC). BVS VERTI-PATCH may finish 15-20 minutes after the material has been placed. The working and finishing times are dependent on ambient and surface conditions.

APPLICATION: BVS VERTI-PATCH should be placed immediately after mixing. The surface of the concrete should be saturated surface dry (SSD) at the time of the application. First force the BVS VERTI-PATCH into the surface voids of the patch area with a trowel to ensure mechanical bonding. Next, continue to fill the patch area then bring the mortar above the level of the existing concrete surface. Allow the mortar to set up to the desired stiffness, shave flush with the side of a trowel to the surrounding surface and then apply the finish. For a smooth finish, use a trowel, sponge float or wood float. For a rough finish, use a broom or a tine.

CURING: Patching applications do not need special curing. However, when premature drying conditions exist (high temperature, direct sunlight, low humidity, strong winds), a water based curing compound can be used.

• The minimum ambient and surface temperatures must be 45º and rising at application time
• Apply only on a clean, sound and properly prepared substrate
• The maximum application thickness is 1/8 inch
• Do not mix over 5 minutes
• Do not apply solvent based curing compounds on BVS VERTI-PATCH
• Protect product from freezing

• Dispose of waste materials in accordance with Federal, State and local regulations
• Component B contains Portland cement and free silica. Avoid breathing dust, use with adequate ventilation. The use of a NIOSH/MSHA approved respirator is recommended.
• Both components are skin and eye irritants, avoid prolonged contact. The use of NIOSH/MSHA approved safety goggles and rubber gloves is recommended.
• In case of contact, flush eyes with water. Wash skin with soap and water. Contact a physician
• For industrial use only
• Keep out of the reach of children
