It is a single <br />component powder that is water activated. KEMROK VR has 20 - 30 <br />minutes working time. <br />KEMROK VR can be applied in an ambient temperature range of 40° 120°F (4.4°C - 48.9°C). KEMROK VR can be trowel applied in multiple <br />lifts of 1/4” - 1/2” (6.35 mm - 12.7 mm) or spray applied (contact Field <br />Engineering for equipment recommendations) in lifts from 1/4” to 3” <br />(6.35 mm - 76.2 mm). KEMROK VR’s crystalline structure and unique <br />chemistry provides exceptional resistance to environments with exposure to <br />Chlorides, Sulfates, Sulfuric acids and more. <br />RECOMMENDED USES: KEMROK VR has been specifically <br />engineered for use in vertical industrial applications such as spall repair <br />and impact damage on beams, columns, pile and pile caps, pressure <br />bearing pre-cast pipe, curbs, steps, pre-stressed panels, tunnels, sewers, <br />loading docks, silos,retaining walls, culverts, catch basins, parapet <br />walls, septic tanks, chemical containments and pre-cast product repair <br />applications where the potential for sulfuric acid exposure is likely. <br />KEMROK VR has been designed to protect both new and existing <br />manholes, wet wells, lift stations and other waste water related structures. <br />KEMROK VR can be hand applied with trowel or used with spray gun <br />equipment. <br />Material Specification: <br />Results provided by licensed engineering test laboratory and represent <br />typical results from production materials. Actual results may vary from third <br />party testing results; however, Aquafin’s materials meet and/or exceed <br />ASTM C928, and exceed established internal quality control standards, <br />(available upon request). All samples were air cured. <br />Site Preparation: <br />• Substrates must be of load bearing capacity, and free from all potential <br />bond breakers such as dirt, dust, grease, oil, sealers, curing compounds, <br />laitance, loose or deteriorated concrete and any bond-inhibiting foreign <br />substances. <br />• Mechanically prepare surfaces to achieve a surface profile equal to CSP <br />5 – 7. Concrete Surface Profile as per ICRI Guideline No. 310.2-1997 <br />(Formerly Guideline No. 03732) <br />• All surfaces to be repaired should be saturated surface dry (SSD) but have</p> <p>Splitting Tensile Strength, psi (MPa) <br />> 400 psi (2.75 MPa) @ 24 hrs <br />ASTM C 496 <br />Bond Strength, psi (Mpa) <br />ASTM C 882</p> <p>> 1,100 psi (7.58 MPa) @ 24 hrs</p> <p>Results provided by licensed engineering test laboratory and represent typical <br />results from production materials.

Hot surfaces should be cooled and shaded while cold <br />surfaces should be heated and sheltered. Mechanically remove all loose <br />materials by suitable means such as chipping hammer, chisel, sandblast, <br />high pressure water blast (>5000 psi), or similar methods. <br />Mixing Instructions: <br />Standard Mixing Procedures (Heavy Duty Drill & Paddle) <br />1. Place KEMROK VR in a suitable, smooth bottom plastic mixing <br />container. <br />2. Dry mix material for 30 seconds. <br />3. Add in 2 qts (1.89 L) of water per 49.5 lb. (22.45 kg) bag of <br />KEMROK VR. <br />4. Mix for 3 1/2 minutes. <br />5. Place material. <br />Standard Mixing Procedures (Mechanical Mixers) <br />1. Pre-wet cement mixer with water then drain all water from mixer (away <br />from repair area). <br />2. Start mixer - KEMROK VR requires a total of 2 qts (1.89 L) of water per <br />49.5 lb. (22.45 kg) unit. Initially, add 50% of total mix water to concrete <br />mixer. <br />3. Add pre-determined units of KEMROK VR. <br />4. Add in remaining mix water. <br />5. Mix for 5 minutes total.</p> <p>Check our website for the latest version of the Technical Datasheet. <br />www.aquafin.net • www.pavemend.com</p> <p>Page 1of 2</p> <p>(04/03/19 SM)</p> <p>Pavemend KEMROK™ VR <br />6. Pour all contents into hod ( for hand trowelling ) or spray apparatus <br />hopper. <br />7. Clean mixer or repeat process for next batch. <br />Application & Finish: <br />Suggested Spray Gun and Hand Trowelled Application Procedures. <br />• Cementitious substrates must be dampened with clean potable water prior <br />to and during installation. Make sure there is no standing water. <br />• Mix KEMROK VR in accordance with the manufacturers <br />recommendations. <br />• For Trowel Applications, install a thin tight coat then immediately double <br />back to achieve a thickness of 0.5” to 1.0” (12.7 mm - 25.4 mm). <br />• For Spray Gun Applications, using low pressure spray equipment, apply <br />on vertical or horizontal surfaces up to 1.0” (12.7 mm) thick. (Contact <br />AQUAFIN Field Engineering for information on suitable pumps, nozzles <br />and applicators.) <br />• For thicker builds, allow initial lift to reach final set, then scarify in a <br />horizontal direction before placing next lift. (Repeat as necessary to reach <br />final profile thickness. <br />• KEMROK VR may be floated using a sponge, rubber, magnesium or <br />wood float designed for this purpose. Avoid placing water on the surface <br />of the KEMROK VR during the floating process as this could lead to <br />surface cracking. Dampen the float with water and not the surface of the <br />KEMROK VR. Finish texture and color can vary depending on the type of <br />float and method used. <br />• Avoid installations in the direct sun as this can decrease working time and <br />cause rapid drying and/or cracking. Plan the work so that a wet edge <br />can be maintained during installation. <br />• Follow Industry recommendations regarding the use of Joints and Sealants. <br />• Working times are influenced by ambient & surface temperatures. For <br />optimum performance, maintain mortar, host concrete to within a range <br />of 40ºF (4.4ºC) and 90ºF (32ºC) prior to, during and for 48 hours after <br />placement of mortar. Working times are influenced by surface temperature <br />and repair profile. Working time can be extended by adding Set Retarder <br />Admixture to mix water. (See Set Retardant TDS for more information). <br />• At low temperatures below 50ºF (10ºC) mortar setting time is extended. <br />• At high temperatures above 86ºF (30ºC) mortar setting time is <br />reduced, affecting placement. Aquafin recommends that repairs at high <br />temperatures be protected from direct sun and heat or be placed early in <br />the morning. Keep materials cool and use cold water for mixing. <br />• Self-curing. <br />• Clean all tools and equipment with water prior to the material reaching <br />final set.</p> <p>Limitations: <br />•D <br /> o not exceed 1.0” (25.4 mm) thickness per lift. <br />•N <br /> ot recommended for placement in temps below 40ºF (4.4ºC) and <br />above 120ºF (49ºC). <br />• Will not bond to polymers or resin coatings. <br />• Do not exceed maximum mix water requirement. <br />Packaging & Shelf Life: <br />• PACKAGING <br />49.5 lb.
