Mapecem 202 (Two-Part)

SKU: 182328
Regular price $45.49
Material
DESCRIPTION
Mapecem 202 is a two-component, shrinkage-compensated, polymer-modified, fast-setting cementitious mortar with a corrosion inhibitor.
Part A & B Sold Seperately

FEATURES AND BENEFITS
For concrete repair and topping applications from 1/4" to 2" (6 mm to 5 cm), or extended up to 20% by weight for thicknesses from 2" to 6" (5 to 15 cm) with 3/8" (10 mm) thoroughly washed, sound, saturated surface-dry (SSD) pea gravel
Requires only the addition of its liquid (Part B), and is prepackaged with both components for easy field use and control
Can be applied using a trowel or screed
Mapecem 202 can be opened to foot and rubber-wheel traffic within 4 hours.
WHERE TO USE
For horizontal, exterior/interior structural concrete repairs and toppings at thicknesses from 1/4" to 2" (6 mm to 5 cm)
For use as a monolithic topping where fast drying is required
When properly mixed and installed, Mapecem 202 has a residual moisture content of less than 2.5% at 24 hours, making it ideal for floor-covering applications in residential, commercial, institutional and industrial structures.
SURFACE PREPARATION
Concrete surface must be clean and free of loose particles, efflorescence, paint, tars, grease, asphaltic materials, bond breakers, curing compounds, wax and any foreign substance.
Mechanically profile clean, sound and stable concrete surfaces to obtain a concrete surface profile (CSP) equal to or greater than #5 per ICRI Guideline #310.2R-2013.
Clean any exposed steel reinforcement and coat with Mapefer 1K or Planibond ® 3C (see the respective Technical Data Sheet for details) to protect against corrosion.
MIXING
Before product use, take appropriate safety precautions. Refer to the Safety Data Sheet for details.
1. Into a clean mixing pail, pour 4/5 of the required amount of latex liquid (Part B).
2. Slowly add the Part A powder to the liquid while mixing, using a low-speed mixer (at 300 to 500 rpm).
3. Add as much of the remaining 1/5 of liquid as needed to achieve the desired consistency. Mix for up to 4 minutes, removing any unmixed powder and remix to a smooth, homogenous consistency.

PRODUCT APPLICATION
Read all installation instructions thoroughly before installation.
1. Before application, ensure that prepared concrete is SSD.
2. Apply with a trowel or a screed, with or without formwork (screed rail), on a horizontal surface.
CURING
Cure with wet burlap or polyethylene sheet during the first 4 hours of curing. Alternately, apply a water-based curing compound conforming to ASTM C309.
CLEANUP
Wash hands and tools promptly with water before the material hardens. Cured material must be mechanically removed.
LIMITATIONS
Do not add other additives, water or cements to Mapecem 202.
Do not use solvent-based curing compounds.
Only use between 45°F and 95°F (7°C and 35°C). Note that cool, damp and humid conditions will slow the rate of hydration and will cause the mortar to retain a higher moisture content for a longer period of time.
