Very Rapid-Hardening, Trowel-Grade, High-Early-Strength Repair Mortar

Planitop 18 TG is a one-component, shrinkage-compensated, very rapid-hardening, trowel-grade, cementitious repair mortar with a corrosion inhibitor. Planitop 18 TG gains strength rapidly and is particularly suited for all horizontal concrete repairs from 1/2" to 2" (12 mm to 5 cm) thickness when applied neat and up to 8" (20 cm) when extended with aggregate.

FEATURES AND BENEFITS
• Very rapid-hardening with more than 15 minutes of working time
• Easy to use, requiring only the addition of potable mixing water
• Easily placed and finished by screed or float
• If applied at 73°F (23°C), Planitop 18 TG can be opened to vehicular traffic within 2 hours of application.
• Can be extended up to 80% by weight with 3/8" (10 mm) pea gravel for thicknesses up to 8" (20 cm)

INDUSTRY STANDARDS AND APPROVALS
• Meets or exceeds requirements for ASTM C928 R3 mortar

WHERE TO USE
• For interior and exterior, horizontal concrete repairs
• For traffic-bearing surfaces
Consult MAPEI's Technical Services Department for installation recommendations regarding uses not listed.

LIMITATIONS
• Use at ambient temperatures at between 32°F and 95°F (0°C and 35°C). For temperatures above 85°F (29°C), use hot-weather guidelines from the American Concrete Institute (ACI). For temperatures below 40°F (4°C), use the ACI’s guidelines for cold-weather applications.
• For applications over 8" (20 cm) thickness, contact MAPEI’s Technical Services Department.
• Do not use Planibond ® 3C as a bonding agent for Planitop 18 TG.

SUITABLE SUBSTRATES
• Properly prepared, structurally sound, fully cured concrete substrates (at least 28 days old)

SURFACE PREPARATION
• Concrete surface must be clean, sound and free of loose particles, efflorescence, paints, tars, grease, asphaltic materials, bond breakers, curing compounds, wax, and any foreign substance or any conditions
that may affect proper bonding of the product and result in cracking, discoloration or changes in overall product performance. Mechanically profile and prepare concrete surfaces by engineer-approved methods, allowing a minimum clearance of 3/4" (19 mm) behind reinforcing steel. For acceptable profile height, reference International Concrete Repair Institute (ICRI) Technical Guideline #310.2R concrete surface profile (CSP) #5 and greater.
• Ensure that the concrete substrate is saturated surface-dry (SSD) before installation of Planitop 18 TG. The concrete surface should be free of any standing water.
• Reference ICRI Technical Guideline #310.1R-2013 and ACI RAP Bulletin 7 for repair geometry, surface
preparation and material application details.

MIXING
Before product use, take appropriate safety precautions. Refer to the Safety Data Sheet for details.
1. Into a clean mixing container, pour 3/4 of the quantity of 2.8 U.S. qts. (2.65 L) of cool, clean potable water per 50-lb. (22.7-kg) bag. Add the remaining water as needed to achieve the desired consistency.
2. For best results, mix Planitop 18 TG by drill mixing or in a mortar mixer. Slowly add Planitop 18 TG to water while mixing. For drill mixing, use a low-speed drill and a Jiffy mixer. Mix for 2 to 3 minutes to a smooth, homogenous consistency.
3. For an extended mix, add up to 80% by weight (40 lbs. [18.1 kg]) of clean, washed, SSD 3/8"
(10 mm) pea gravel per 50-lb. (22.7-kg) bag.

PRODUCT APPLICATION
Read all installation instructions thoroughly before installation.
1. Apply a scrubcoat of Planitop 18 TG directly over the SSD prepared surface.
2. Place Planitop 18 TG immediately over the scrubcoat and finish it to the surrounding concrete texture by float or screed. Application times will vary depending on climatic conditions.

CLEANUP
• Wash hands and tools promptly with water before material hardens. Cured material must be mechanically removed. 

CURING AND PROTECTION
• During curing, protect Planitop 18 TG from high wind conditions and keep ambient temperatures at between 45°F and 85°F (7°C and 29°C).
• An ASTM C309 curing compound or an ASTM C1315 cure and seal can be utilized.
• Protect from freezing for 12 hours after application.
