<strong>Planitop</strong> <strong>18</strong>®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 <strong>Planitop</strong> <strong>18</strong>.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 <strong>Planitop</strong> <strong>18</strong> 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.[<strong>18</strong>,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 <strong>Planitop</strong> <strong>18</strong> 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 <strong>Planitop</strong> <strong>18</strong> 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 <strong>Planitop</strong> <strong>18</strong> 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).
