Vantek - V-Krete Repair Mortar Information Sheet

VANTEK Concrete Restoration and Protection V-KRETE is excellent for all types of concrete repair applications: bridge decks, concrete pavements, concrete joints, airport runways, livestock building floors and walls, industrial floors, loading docks, general concrete, dowel bar retrofit, pre-stressed and precast. V-KRETE is specifically designed for those applications requiring very rapid strength gain. Benefits & Features • Made in USA • High early strength – open to traffic in 3 hours • Extremely dense; Low permeability • Non-corrosive • Increased durability and freeze-thaw resistance; excellent adhesion; improves flexural strength • Aggregate extension: Up to 60 % on repairs greater than 2”/5.1 cm (use clean dry pea gravel or small rock) • Shrinkage compensation minimizes cracking from drying shrinkage • Ready to use; easily mixed with water on the jobsite • Use with Polymer V Epoxy Emulsion or Vantek Acrylic Resin for added bond strength (primer) and to minimize absorption (admix).

Shelf Life: 1 year in original unopened container Storage Conditions: Store in unopened container in a dry and cool area Apply only when the surface and ambient temperature are 45-50°F (7-10°C) and rising. Applications made during temperatures greater than 85°F (29°C) should follow Hot Weather Application guidelines, per ACI. The minimum required thickness is 1/2 inch (12.6mm) for best results. Do not add more water than specified. Do not add additional powder from other units. Do not over mix or retemper. Do not apply to a dry substrate. Applying less than 1/2 inch reduces the ultimate strength of the mortar. V-KRETE is a pure cement-based blend of specialty aggregates and admixtures providing a rapid setting, high strength, durable concrete repair. Unique non-slump formula. Excellent resistance to salts, mild chemicals and livestock traffic. V-KRETE is pre-mixed, requiring only the addition of potable water. This unique mortar provides outstanding results and enables the project to be completed more rapidly than with conventional patching & repair materials. It can be used with Polymer V Epoxy Emulsion or Vantek Acrylic Resin for added bonding strength (primer) and resistance to absorption (admix). Production Description Industry Uses V-Krete Repair Mortar Limitations/Warnings

Use V-KRETE at a preconditioned temperature of 71 ± 5° F (22 ± 3° C). Use 5.25 – 5.75 (2.5 – 2.7L) pints of water or mixing liquids per 50lb (27.2kg) bag. Small Batch: Mix 1-part liquids with 4 to 5 parts mortar. Mixing must be achieved mechanically using a slow speed, 1/2 inch (12.7mm) drill and mixing paddle. Mix while slowly adding the powder to the water or mixing liquids. Mix smaller batches for small repairs or repairs in tight areas. Mix up to 4 minutes to a uniform lump-free consistency. Avoid over mixing which could entrap air. Note: In Hot Weather, add 1 pouch of SLOW SET Additive per gallon (3.8L) of mixing liquids to extend the working time 15-20 minutes. Just dissolve the SLOW SET into the mixing liquids. USING WITH POLYMER V or ACRYLIC RESIN as ADMIX AND BONDING AGENT General Repairs: Mix 1 part POLYMER V or ACRYLIC RESIN with 3 parts water for ADMIX & PRIMING. Thin and Performance Overlays: Increase the concentration of polymer or resin to enhance the properties. Typically 1-gallon of POLYMER V or ACRYLIC RESIN is needed for 3 bags MORTAR for General Repairs. Vantek warrants for a period of one (1) year that its products will be free of manufacturing defects and will be in conformity with published specifications when handled, stored, mixed, and applied in accordance with recommendations of Vantek. If any product fails to meet this warranty, the liability of Vantek will be limited to replacement of any non-conforming material if notice of such nonconformity is given to Vantek within (1) one year of delivery of materials. Vantek may in its discretion refund the price received by Vantek in lieu of replacing the material. No customer, distributor, or representative of Vantek is authorized to change or modify the published specifications of this warranty in any way. No one is authorized to make oral warranties on behalf of Vantek. In order to obtain replacement or refund the customer must provide written notice containing full details of the non-conformity.

Limited Warranty Safety Considerations • Use adequate ventilation. • Use of NIOSH/MSHA approved dust vapor respirator, safety goggles and protective gloves are recommended. First Aid • EYE CONTACT: Flush immediately with water for at least 15 minutes. Contact physician immediately. • RESPIRATORY CONTACT: Remove person to fresh air. If the discomfort persists, breathing difficulty occurs, or if swallowed seek medical attention. • SKIN CONTACT: Remove any contaminated clothing. Wash skin thoroughly with soap and water. If irritation persists, seek medical attention. KEEP CONTAINER TIGHTLY CLOSED – KEEP OUT OF REACH OF CHILDREN – NOT FOR INTERNAL CONSUMPTION – FOR INDUSTRIAL USE ONLY Surface Preparation (See ICRI guidelines) 1. Concrete must be sound and fully cured (28 days). 2. Saw cut the perimeter of the area being patched into a square with a minimum depth of 1/2" (12.5 mm) for a uniform repair zone over a floor. 3. Remove all unsound concrete and roughen the surface to min. 1/4" (6.35mm) profile for overlayments. 4. Remove all laitance, oil, grease, curing compounds, and other contaminants that could prevent adequate bond. 5. If acid etching, follow guidelines. A visual etch should be present. 6. The concrete substrate should be saturated surface dry (SSD), without standing water, before application. Prime the substrate with a wet solution of mortar and water or resin/water mix to enhance the bond. 7. Apply the mixed material onto the prepared saturated surface dry (SSD) substrate by trowel or screed. Ensure proper consolidation of the mortar and compaction around reinforcing steel. Minimum application thickness is 1/2” (12.5 mm) based on a 3/8” (9.5 mm) diameter max. coarse aggregate. Straight mortar may be applied at 1/4” (6.35 mm) thickness. Finish the completed repair, as required, taking care not to overwork the surface. 8. For repairs over 2” (50.8 mm) deep the material should be extended 50% by weight with clean, SSD, 3/8” (9.5 mm) pea gravel or rock conforming to ASTM C 33. 9. For enhanced bond and to minimize absorption, use POLYMER V or ACRYLIC RESIN mixed with water as a primer. 10. Top Coating with 440LV EPOXY or V-GARD: During initial set apply a light broom or textured finish to the V-KRETE surface. A light broadcast of 440LV Broadcast Aggregate can also be uniformly spread on the wet mortar surface. Apply the coating or overlay after full mortar cure. Do not use POLYMER V or ACRYLIC RESIN as admix if using epoxy over the top. Reinforcing Steel Remove all oxidation and scale from the exposed reinforcing steel. Prime the exposed steel with RUST STOPPER or VANTEK 803 Epoxy Gel for optimum seal.
