Product Data Sheet
Safety Data Sheet
FEATURES AND BENEFITS
• Prepackaged for easy field use and control
• Optimizes bond to existing concrete substrates
• Improves resistance to abrasion and freeze/thaw cycles
• Non-redispersible

WHERE TO USE
• Use as an admixture for horizontal, vertical and overhead concrete repairs and concrete toppings in exterior and interior applications.
• Use as a slurry bondcoat when mixed with Portland cement to enhance adhesion of mortars and toppings to concrete substrates.
• Use with cement plaster and stucco to increase adhesion and to reduce cracking.
• Use Planicrete AC with specified MAPEI products to improve adhesion, product performance and curing. See applicable Technical Data Sheets (TDSs) for details.
• Use as an admixture for interior or exterior floating toppings where a minimum thickness of 1-3/8" (3.5 cm) or greater can be placed on top of a cleavage membrane and proper reinforcement.
• Use in repair mortars and toppings to improve resistance to freeze/thaw cycles and to reduce permeability to de-icing salts.
• Planicrete AC is ready to use, concentrated and non-redispersable, according to the American Concrete Institute (ACI).

SURFACE PREPARATION
• All substrates must be structurally sound, stable and solid, with all loose materials removed.
• Thoroughly clean the surface of any substance that could interfere with the bond of the installation material, including dirt, paint, tar, asphalt, wax, oil, grease, latex compounds, form release agents, laitance, loose toppings, foreign substances and any other residues.
• Concrete surfaces must be mechanically profiled and prepared in
accordance to the repair mortar or stucco that will be used in conjunction with Planicrete AC.
• Reference International Concrete Repair Institute (ICRI) concrete surface profiles #2 to #5 for plaster and stuccos, and greater than #5 for slurry bond coats for bonded repairs and toppings.
• Concrete substrate and ambient room temperatures must be between 45°F and 95°F (7°C and 35°C) before application. Temperatures must be maintained within this range for at least of 72 hours after the installation of repair mortars and toppings.

MIXING
Before product use, take appropriate safety precautions. Refer to the Safety Data Sheet for details suggested dilution ratios
• Standard ratio: 1 part Planicrete AC to 3 parts water (1:3) – used for standard mortars, pointing mortars, plaster and stucco.
• Improved performance ratio: 1 part Planicrete AC to 2 parts water (1:2) – used for repair mortars.
• Better performance ratio: 1 part Planicrete AC to 1 part water (1:1) – used for repair mortars.
• Best performance ratio for reduced shrinkage to wear surfaces: 2 parts Planicrete AC to 1 part water (2:1) – used for large overlays and toppings.
• Slurry bondcoat: Use undiluted Planicrete AC mixed with Portland cement. Periodically agitate the slurry bond coat as settling may occur in the mixing container over time.
Mixing in a pail
1. Into a clean mixing pail, pour 4/5 of the required amount of Planicrete AC.
2. Slowly add a cement/sand mix to the liquid while mixing, using a low-speed mixer. Next add the remaining 1/5 of mixed Planicrete AC to achieve the desired consistency. Mix for up to 4 minutes, to a smooth, homogenous consistency.
3. Do not overmix.
Mortar or concrete mixer
1. Stop mixing paddles when adding mixed Planicrete AC to the mixer.
2. Start the mixer at a slow speed and add cement, sand and aggregates per the mix design. During the mixing process, adjust the quantity of liquid to ensure a plastic consistency.
3. Do not overmix.
