TMPlanitop ® 18Fast-Setting, FlowableOne-Component RepairMortarCORROSIONINHIBITORE N H A N C E DDESCRIPTIONPlanitop 18 is a one-component, shrinkage-compensated, fast-setting,cementitious repair mortar with corrosion inhibitor. It is suited for all interior/exterior horizontal concrete repairs, including bridge-deck overlays, parkinggaragefloor repairs and various horizontal DOT concrete repairs.USES• Use for horizontal structural concrete repairs and restoration from 1/2"to 2" (12 mm to 5 cm) in thickness. Planitop 18 can be placed in largequantities in horizontal applications and is suited for precast, cast-in-place,post-tensioned or prestressed concrete repair.• Use for the renovation and resurfacing of concrete structures such as airportrunways, balconies, bridge decks, concrete pavement, manufacturing floors,parking decks, tunnels and warehouse floors.• Use for the renovation of concrete surfaces subject to extreme exposureand heavy vehicular traffic, including roads, ramps, industrial floors, piers,sidewalks and canals.• Use where turnaround time is at a premium, as Planitop 18 is open tovehicular traffic within 1 hour of application.RECOMMENDED SUBSTRATES• Properly prepared masonry and concrete at least 28 days old, stable andfree of hydrostatic pressureContact MAPEI’s Technical Services Department for installation recommendationsregarding substrates and conditions not listed.TECHNICAL NOTES• Planitop 18 is rapid-setting, providing excellent compressive and flexuralstrength. Planitop 18 also provides higher resistance to abrasion thanordinary repair mortars.• Planitop 18 requires only the addition of water, and is premeasured for easyfield use and control.• Planitop 18 can be placed easily using either a screed or trowel and thencan be finished easily.• Planitop 18 adheres well to old concrete surfaces and has good resistanceto freeze/thaw conditions and de-icing salts. Before application of Planitop18, mechanically roughen, saturate surface-dry (SSD) and scrub-coat theconcrete surface to ensure a secure bond. Use reinforcement bars for addedstrength as needed.• Planitop 18 is a flowable mortar that can be extended up to 80% by weightwith selected aggregate for deeper applications.• Planitop 18 has low chloride permeability, which helps to protect embeddedsteel against corrosion.• Planitop 18 can only be used between 45°F and 95°F (7°C and 35°C).• Do not use as an anchoring material.

Planitop 18®INSTRUCTIONS1. Surface Preparation1.1 All substrates must be structurally sound, stable andsolid.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 and any other residues.1.3 Concrete surfaces must be mechanically profiled andprepared by shotblasting, sandblasting, waterjetting,scarifying or other engineer-approved methods toachieve a profile of +/- 1/8" (3 mm). Reference ICRI CSPStandards 7 to 9 for acceptable profile height.1.4 Concrete substrate and ambient room temperaturesmust be between 45°F and 95°F (7°C and 35°C) beforeapplication. Maintain temperatures within this range forat least 12 hours after the installation of Planitop 18.1.5 Do not apply over standing water or wet surfaces.2. Mixing2.1 Into a clean mixing container, pour the required amountof cool, clean potable water for the desired applicationcharacteristics, from 3 to 3.23 U.S. qts. (2,84 to 3,06 L)per 50-lb. (22,7-kg) bag.2.2 Slowly add Planitop 18 to water while mixing, using alow-speed mixer. Mix for 2 to 3 minutes, removing anyunmixed powder, and remix for another 1 to 2 minutes toa smooth, homogenous consistency.2.3 For extended mix, add up to 80% by weight (40 lbs.[18,1 kg]) of washed, clean, saturated surface-dry (SSD)3/8" (10 mm) graded aggregate per 50-lb. (22,7-kg) bag.2.4 Do not overmix. Overmixing or moving the mixer upand down during the mixing process could cause airentrapment, which could shorten pot life.2.5 Do not mix more material than can be applied within 15minutes.3.3 For large repair areas, use Mapecem ® 102 or Mapecem202 (see respective Technical Data Sheet for details).For application thicknesses less than 1/2" (12 mm), useMapecem 101 (see Technical Data Sheet for details).3.4 Planitop 18 has a pot life of about 15 minutes at 73°F(23°C). Place material within its pot life. Applicationtimes will vary depending on climatic conditions.4. Curing4.1 During curing, protect Planitop 18 from excessive heator draft conditions, which could cause cracking.4.2 Mist-spray the surface with water as soon as possibleduring the first 24 hours of damp curing. Alternatively,use damp burlap, a white polyethylene sheet or MAPEI’sPlanicure ® 65 white liquid curing compound (seeTechnical Data Sheet for details). Do not use a solventbasedcuring compound.5. CleaningWash hands and tools promptly with water before materialhardens. Cured material must be mechanically removed.3. Application3.1 Planitop 18 is applied with a trowel, without formwork,on horizontal surfaces. The maximum thickness per coatis 2" (5 cm).3.2 When encountering exposed reinforcing steel bars, cleanbars and coat with Mapefer 1K or Planibond ® 3C toprotect against corrosion and to improve adhesion (seethe respective Technical Data Sheet for details).
