Features & Benefits

• When mixed with water it forms a fluid micro-concrete suitable for casting into formwork without segregating in layers from 2 to 8 cm thick, and without the need for electro-welded reinforcing mesh
• To allow the product’s expansive properties to develop fully and correctly, Planitop HPC Floor 46 must be mixed with water and cured in a damp environment
• To allow expansion in the open air, Planitop HPC Floor 46 may also be admixed with 0.25% of Mapecure SRA, a special admixture which has the capacity to reduce plastic and hydraulic shrinkage
• Mapecure SRA carries out an extremely important role and guarantees better curing of the micro-concrete
• When mixed with Planitop HPC Floor 46 it may be considered a technologically advanced system, in that the admixture has the capacity to stop the water evaporating too quickly from the micro-concrete and encourages the development of hydration reactions
• Mapecure SRA acts basically as an internal curing agent and, thanks to its interaction with some of the main components in the cement, it reduces final shrinkage by 20% to 50% compared with the same product without the admixture, which means there is also a lower risk of cracking
• The use of Mapecure SRA may reduce mechanical performance characteristics slightly by 5-6%
• The product may also be used without adding Mapecure SRA when climatic conditions allow a favourable curing cycle to be carried out
• Once hardened, Planitop HPC Floor 46 has the following characteristics:
• Very high flexural and compressive strength
• High ductility
• High resistance to cyclical loads
• Impermeable to water
• Excellent adhesion to old concrete, if dampened with water before application, and to rebar, especially if treated beforehand with Mapefer or Mapefer 1K
• High resistance to wear from abrasion or impact loads
• Complies with the principles defined in EN 1504-9 (“Products and systems for protecting and repairing concrete structures: definitions, requirements, quality control and conformity assessment. General principles for the use and application of systems”), and the minimum requirements of EN 1504-3 (“structural and non-structural repairs”) for R4-class structural mortars
• Planitop HPC Floor 46 is covered by the Certificate of Technical Assessment (CVT) n° 264/2020 released by 2^ Div. II of STC - CSLP.v

Recommendations & Limitations

• Do not use Planitop HPC Floor 46 for anchoring elements accurately in place (use Mapefill or Mapefill R)
• Do not use Planitop HPC Floor 46 on smooth concrete substrates
• Do not apply Planitop HPC Floor 46 by spray or with a trowel (use Planitop HPC Tixo applied by trowel.)
• Do not add cement or admixtures to Planitop HPC Floor 46
• Do not add water once the mix has started to set
• Do not use Planitop HPC Floor 46 if the bag is damaged or if it has been opened previously
• Only use bags of Planitop HPC Floor 46 which have been stored on their original, covered pallets
• In hot weather, store the product in a cool area and use cold water to prepare the mix
• In cold weather, store the product in a closed area at a temperature of +20°C and protect from frost. Use lukewarm water to prepare the micro-concrete
• Mapei recommend curing Planitop HPC Floor 46 carefully immediately after pouring to prevent the mixing water evaporating off too quickly, especially in hot or windy weather, otherwise surface cracks may appear. Protect Planitop HPC Floor 46 at all times by spraying the surface with a water mist while pouring operations are being carried out. Then immediately cover it with waterproof sheets and keep covered for at least 5 days
