It <br />is designed for use as a concrete screed or repair mortar at depths of <br />3/8” – 6” (10 mm – 152 mm). This product offers normal set times and a <br />mid-range slump for easy workability. <br />Typical Applications: <br />• Interior and exterior horizontal concrete slabs <br />• Balconies, sidewalks, curbs, parking decks and ramps <br />• To level concrete surfaces <br />• Deteriorated joint edges <br />• Can be used as a separation screed <br />• For overlays up to 5” (127 mm) neat <br />• For screed repairs up to 6” (152 mm) neat w/min. #4 bar <br />Advantages: <br />• Fiber-reinforced and polymer-modified <br />• No shrinkage when properly cured <br />• Corrosion inhibitor and silica fume enhanced <br />• One-component - just add water <br />• Accelerated cure - allows for installation of moisture sensitive toppings <br />within 12 hours. <br />• Excellent bond to properly prepared concrete <br />Substrate Preparation: <br />• Concrete surfaces must be structurally sound, free of any loose or <br />deteriorated concrete, dirt, dust, grease, oil, sealers, curing compounds <br />and all other bond-inhibiting materials. <br />• Mechanically prepare surfaces to achieve a surface profile equal to <br />CSP 5 - 7 as per ICRI Guideline No. 310.2R-13. <br />• Properly clean profiled area by water-blasting. All surfaces must be <br />saturated surface dry (SSD) but with no standing water, immediately <br />prior to application. <br />• Repair areas must have saw cut straight edges with a minimum 3/8” (10 <br />mm) depth as per ICRI Guideline 310.1R – 2008. <br />Priming: <br />Steel: All exposed steel must be mechanically cleaned to a white metal <br />finish and primed with 2 coats (20 mils per coat) of Aquafin’s REBAR <br />PRIMER/BOND-CI. <br />Concrete: Must be primed with scrub coat of MORTAR-Screed CI.

Alternately, can be <br />primed with a spray or brush coat of REBAR PRIMER/BOND-CI <br />Mixing: <br />Mixing Ratio: 2.5 – 2.75 qts. (2.4 – 2.6 L) water per 50 lb. bag. <br />(yield is approx .40 cu.ft. at 2.5 qts water and 2.75 qts water) <br />• For best results, mechanically mix at slow speed with a 3/4” drill <br />and “eggbeater” style mixing paddle. Use a paddle type mortar <br />mixer for large jobs. <br />• Add the appropriate amount of potable water into a clean mixing <br />bucket. Gradually add powder while mixing continuously. <br />• Mix at slow speeds to prevent entraining air for a minimum of 3 <br />minutes until a lump-free consistency is achieved.</p> <p>Page 1 of 2</p> <p>(updated 02/23/21 - EKVB)</p> <p>MORTAR-Screed CI <br />• Only mix enough material that can be placed within 30 - 45 minutes. <br />DO NOT OVERWATER! If too much water is added, the mixture will <br />segregate resulting in uneven surface strengths. Surfaces with reduced <br />strength must be removed mechanically. <br />Application: <br />Read all instructions thoroughly prior to installation. <br />1. Only proceed with application when the temperatures remain between <br />40°F and 90°F (4°C and 32°C) and protect from freezing for <br />24 hours after application. For temperatures above 85°F (29°C), <br />follow ACI hot-weather application guidelines to ensure a successful <br />installation. <br />2. Immediately after mixing, place MORTAR-Screed CI onto the surface <br />area and work it into the substrate to obtain a mechanical bond. <br />Spread with a trowel, comealong concrete rake or screed to a <br />thickness that matches pre-set elevation points. On large areas, use <br />screed strips or forms. Screed to level with hand held straightedge or <br />vibratory screed. <br />3. Finish material to desired finish texture (can be power troweled). <br />4. MORTAR-Screed CI can be placed in lifts up to 6“ (152 mm) when <br />used in situations where rebar matting/rebar cage configurations meet <br />ASTM, ACI and ICRI Guidelines (Minimum #4 bar - upper and lower <br />mat). <br />5. Follow ACI guidelines for hot and cold weather concreting. <br />6. Protect from freezing for 24 hours after application. <br />7. Always re-establish expansion and control joints when using this product.</p> <p>Safety: <br />Refer to SDS. <br />LIMITED WARRANTY: AQUAFIN, INC. warrants this product for a period of one year from <br />the date of installation to be manufactured free of defects and to be consistent with its technical <br />properties as stated in our current Technical Data Sheet.
