Features & Benefits

• When Planitop HPC Floor is mixed with water, it forms a fluid mortar suitable for casting into formwork in layers from 1 to 4 cm thick without segregating, and without the need for electro-welded reinforcing mesh
• To allow the product’s expansive properties to develop fully and correctly, Planitop HPC Floor must be mixed with water and cured in a damp environment. To allow expansion in the open air, Planitop HPC Floor may also include 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 mortar. When mixed with Planitop HPC Floor it may be considered a highly advanced technological system, in that the admixture has the capacity of stopping the water evaporating too quickly and encourages the development of the hydration reactions
• SRA acts basically as an internal curing agent and, thanks to its interaction with some of the main components in the cement, reduces final shrinkage by 20% to 50% compared with the same product without the admix, 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
• 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 reinforcement rods, especially if treated beforehand with Mapefer or Mapefer 1K
• High resistance to wear due to abrasion or impact
• 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 and EN 1504-6 (“Anchoring rebar”)
• Covered by the Certificate of Technical Assessment (CVT) n° 264/2020 released by 2^ Div. II of STC - CSLP

Recommendations & Limitations

• Do not use Planitop HPC Floor on smooth concrete substrates
• Do not use Planitop HPC Floor for anchoring elements accurately in place (use Mapefill or Mapefill R)
• Do not apply Planitop HPC Floor by spray or with a trowel (use Planitop HPC Tixo applied by trowel)
• Do not add cement or admixtures to Planitop HPC Floor
• Do not add water once the mix has started to set
• Do not use Planitop HPC Floor if the bag is damaged or if it has been opened previously
• Only use bags of Planitop HPC Floor 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 mortar
• After stripping the formwork, Mapei recommend curing Planitop HPC Floor carefully to prevent the mixing water evaporating off too quickly, especially in hot or windy weather, otherwise surface cracks may appear. While pouring the mix, spray water on the mortar and then repeat this operation at regular intervals (every 3-4 hours) for at least the first 48 hours. Then cover the surface with waterproof sheets and keep covered for at least 5 days
