TM<strong>Mapecem</strong> ®<strong>202</strong>Medium-build,two-component,fast-setting mortarCORROSIONINHIBITORE N H A N C E DDESCRIPTION<strong>Mapecem</strong> <strong>202</strong> is a two-component, shrinkage-compensated, polymer-modified,fast-setting cementitious mortar with a corrosion inhibitor. <strong>Mapecem</strong> <strong>202</strong> isintended for the renovation <strong>and</strong> topping of interior/exterior horizontal concretesurfaces. <strong>Mapecem</strong> <strong>202</strong> is excellent for heavy-duty industrial applications thatinclude manufacturing floors, loading docks <strong>and</strong> tipping floors for smeltingmetals, where fast drying is required to allow traffic within 3 to 4 hours. <strong>Mapecem</strong><strong>202</strong> achieves an impressive compressive strength of 6,700 psi (46,2 MPa) in 28days.When properly mixed, <strong>Mapecem</strong> <strong>202</strong> has a residual moisture content of less than2.5% within 24 hours. It applies easily onto horizontal surfaces in thicknessesof 1/4" to 2" (6 mm to 5 cm) maximum per placement. For filling deeper spaces(up to 8" [20 cm]), add up to 20% by weight of 1/4" to 3/8" (6 to 10 mm) washed,nonreactive aggregate SSD (saturated surface-dry) aggregate to the <strong>Mapecem</strong> <strong>202</strong>.traffic. <strong>Mapecem</strong> <strong>202</strong> achieves an impressive compressive strengthgreater than 2,200 psi (15,2 MPa) in 4 hours, 3,100 psi (21,4 MPa) in24 hours <strong>and</strong> 6,500 psi (44,8 MPa) in 28 days.• Use as a monolithic topping where fast drying is required. <strong>Mapecem</strong> <strong>202</strong>can be opened up to traffic within 3 to 4 hours. When properly mixed<strong>and</strong> installed, <strong>Mapecem</strong> <strong>202</strong> has a residual moisture content of less than2.5% at 24 hours.RECOMMENDED SUBSTRATESProperly prepared masonry <strong>and</strong> concrete at least 28 days old, stable <strong>and</strong> freeof hydrostatic pressureContact MAPEI’s Technical Services Department for installation recommendationsregarding substrates <strong>and</strong> conditions not listed.USES• Use for horizontal exterior <strong>and</strong> interior structural concrete repairs <strong>and</strong>concrete topping from 1/4" (6 mm) up to thickness of 2" (5 cm).<strong>Mapecem</strong> <strong>202</strong> can be placed in large quantities on horizontal applications<strong>and</strong> is suitable for precast, cast-in-place, post-tensioned or prestressedconcrete repair.• Use for renovating <strong>and</strong> resurfacing interior horizontal concrete substratesfound in residential, commercial <strong>and</strong> institutional structures.• Use for renovating concrete surfaces of residential, commercial <strong>and</strong>institutional structures that are subject to foot traffic <strong>and</strong> rubber-wheelTECHNICAL NOTES• <strong>Mapecem</strong> <strong>202</strong> provides excellent compressive <strong>and</strong> flexural strength forapplications 1/4" (6 mm) to 2" (5 cm) for concrete repairs <strong>and</strong> topping.<strong>Mapecem</strong> <strong>202</strong> also has higher resistance to abrasion than ordinary cement<strong>and</strong> s<strong>and</strong> repair screeds.• <strong>Mapecem</strong> <strong>202</strong> requires only the addition of its liquid (Part B) <strong>and</strong> isprepackaged for easy field use <strong>and</strong> control. Do not add other additives,water or cementsto <strong>Mapecem</strong> <strong>202</strong>.• <strong>Mapecem</strong> <strong>202</strong> can be applied using a trowel or screed. Approved substratesmust meet L/360 deflection requirements.
<strong>Mapecem</strong> ®<strong>202</strong>2 • <strong>Mapecem</strong> <strong>202</strong> adheres well to existing properly preparedconcrete surfaces. Before application of <strong>Mapecem</strong> <strong>202</strong>,mechanically roughen concrete surface, saturatesurface-dry (SSD) <strong>and</strong> scrubcoat to ensure a securebond. Apply a bonding agent (Planibond ® 3C orPlanibond EBA [see respective Technical Data Sheets fordetails]) or <strong>Mapecem</strong> <strong>202</strong> as a scrubcoat to the properlyprepared surface. Quickly apply the <strong>Mapecem</strong> <strong>202</strong> mixwhile the scrubcoat is still wet. If scrubcoat dries beforeto placement of the mortar, it will become a bond breaker<strong>and</strong> the application will fail.• <strong>Mapecem</strong> <strong>202</strong> is not a construction grout, so itcannot be used for anchoring purposes or pouringinto formwork. Instead, use MAPEI's Planigrout ®740, Planigrout 750 or Planigrout 780 (see respectiveTechnical Data Sheets for details) for anchoring <strong>and</strong>Planitop ® 15 (see Technical Data Sheet for details) forpouring into formwork.• A waterproofing membrane, such as Mapelastic HPG(see Technical Data Sheet for details), can be appliedon top of <strong>Mapecem</strong> <strong>202</strong> in as few as 3 hours afterplacement.• <strong>Mapecem</strong> <strong>202</strong> can only be used between 45°F <strong>and</strong> 95°F(7°C <strong>and</strong> 35°C).Note: Cool, damp <strong>and</strong> humid conditions will slow therate of hydration <strong>and</strong> will cause the topping to retain ahigher moisture content for a longer period of time.INSTRUCTIONS1. Surface Preparation1.1 All substrates must be structurally sound, stable <strong>and</strong>solid, with all loose materials removed.1.2 Thoroughly clean the surface of any substance thatcould interfere with the bond of the installation material,including dirt, paint, tar, asphalt, wax, oil, grease,latex compounds, form release agents, laitance, loosetoppings, foreign substances <strong>and</strong> any other residues.1.3 Concrete surfaces must be mechanically profiled <strong>and</strong>prepared by shotblasting, s<strong>and</strong>blasting, waterjetting,scarifying or other engineer-approved methods to obtaina +/- 1/8" (3 mm) profile. Reference ICRI CSP St<strong>and</strong>ards7 to 9 for acceptable profile height.1.4 Concrete substrate <strong>and</strong> ambient room temperaturesmust be at least 45°F (7°C) <strong>and</strong> must not exceed95°F (35°C) before application. Temperatures must bemaintained within this range for at least 72 hours afterthe installation of <strong>Mapecem</strong> <strong>202</strong>.1.5 Do not apply over st<strong>and</strong>ing water or wet surfaces.2. Mixing2.1 Into a clean mixing pail, pour 4/5 of the required amountof cool liquid (Part B).2.2 Slowly add <strong>Mapecem</strong> <strong>202</strong> to the liquid while mixing,using a low-speed mixer. Next add the remaining 1/5 ofliquid to achieve the desired consistency. Mix for up to 4minutes, removing any unmixed powder <strong>and</strong> remix to asmooth, homogenous consistency.2.3 For extended mix, add 20% by weight (11 lbs. [4,99 kg])of washed, clean, SSD 3/8" (10 mm) pea gravel.2.4 Do not overmix. Overmixing can cause air entrapment,which could shorten pot life.2.5 Do not add water to material, or <strong>Mapecem</strong> <strong>202</strong> will notperform as specified.2.6 Do not mix more material than can be applied within a30-minute period.3. Application3.1 <strong>Mapecem</strong> <strong>202</strong> can be applied with a trowel or a screed,with or without formwork (screed rail), on a horizontalsurface. The maximum thickness neat is 2" (5 cm). Useextended mix for deeper repair patching up to 8" (20 cm)thick.3.2 When encountering exposed reinforcing steel bars, cleanbars <strong>and</strong> coat with Planibond 3C (see Technical DataSheet for details) to protect against corrosion <strong>and</strong> toimprove adhesion.3.3 Complete renovation by applying <strong>Mapecem</strong> 101 (seeTechnical Data Sheet for details) to the repair <strong>and</strong>adjoining area to provide a durable uniform appearance.4. CuringDo not wet-cure; however, protect the placed material fromexcessively hot or drafty conditions with wet burlap during thefirst 4 hours of curing. Excessive heat <strong>and</strong>/or wind could causepremature surface drying <strong>and</strong> result in cracking.5. CleaningWash h<strong>and</strong>s <strong>and</strong> tools promptly with water before materialhardens. Cured material must be mechanically removed.
