Machine application ASOCRET-HFF can be mechanically applied. For precise information, see the additional Technical Information No. 43. The discharge dimension must be continuously checked with mechanical application. This is done using a PFT consistency test socket. The discharge dimension must be determined on a moistened glass plate and should be approx. 60 cm.
Suitable substrate Concrete substates in accordance with DIN 1045 Heated and unheated cement-based screeds in accordance with DIN EN 13813 Rapid cement screeds
Preparing the substrate Requirement for substrate 1. Dry 2. Firm 3. Free of adhesion inhibiting substances 4. The substrate must correspond to the load-bearing capacities in accordance with DIN 1055. 5. The tear-off strength of concrete substrates must not exceed an average of 1.5 N/mm² (lowest individual value 1.0 N/mm²).
Preparing the surface 1. Remove oil wax residues using ASO-R008. 2. Prime cementitious substrates with a moisture content of < 4% and water vapour resistance factor of < 0.6 g/m² h with AQUAFIN-PRIMER. 3. In substrates with rear-sides or increased moisture load in exterior areas, with old, firmly adhering epoxy resin coatings or increased mechanical loads, prime with ASODUR-SG2 or ASODUR-SG3-thix and then sprinkle with plenty of quartz sand with an aggregate grain of 0.5–1.0 mm. After the reaction has taken place (approx. 16 hrs), brush off any excess quartz sand. 4. Old, firmly adhered, load-bearing reaction resin coatings must be ground before coating with ASOCRET-HFF and primed with ASODUR-SG2 or ASODUR-SG3-thix. 5. The temperature of the air, material and substrate may not fall below +5°C during application, and during the following week. 6. In the case of substrates damaged by de-icing salt, the substrate must be removed down to the neutral area using suitable measures. 7. Fill deeper damaged areas and holes using ASOCRET BIS system, cracks must be filled with ASODUR-GH-S. 8. In the vicinity of adjacent walls and other ascending building components, a self-adhesive edge strip, e.g. RD-SK50, must be provided in order to prevent straining of the material. Existing joints in the substrate must be brought through, the flow of material in these joints must be prevented using suitable measures.
Application Mixing 1. Fill the water into a clean mixing bucket and mix with the powder component with a stirrer to produce a homogeneous, lump-free mass. 2. In between, scrape the unmixed material from the side walls with a trowel and feed it to the mixing process. 3. The mixing time is ca. 3 - 5 minutes. 4. After a settling period of ca. 2 minutes, thoroughly homogenise the compound again.

Technical data sheet ASOCRET-HFF Application 1. Pour ASOCRET-HFF onto the primed substrate, and use a suitable tool (surface rake, long-handled rake) to distribute it evenly during the pot life up to the desired height level. Apply the required layer thickness in one application step and deaerate the still liquid layer with a spiked roller or encourage it to flow. 2. Coloured seals can be created with ASODUR-V360W. The surface coated with ASOCRET-HFF must be checked beforehand to ascertain whether it needs to be prepared by grinding, etc. 3. Applications in exterior areas or surfaces with increased moisture pressure, coating with ASODUR-B351 is required. 4. After removing the protruding edging strips, connecting joints must be sealed with INDUFLEX-PU. 5. The coating must be protected against weathering influences, e.g. strong solar radiation, wind loads etc., and against mechanical damage or loads using suitable measures in the first 24 hours. 6. ASOCRET-HFF can be driven on by vehicles that have soft tyres after approx. 24 hours. After 48 hours, the surface can be driven on by forklift vehicles. With vehicles fitted with polyamide tyres, there is a risk of surface damage and they should therefore be ruled out.
Cleaning tools Clean tools thoroughly with water after use.
Storage conditions Storage Store in a cool and dry place. Min. 12 months in the original canister. Promptly use opened container.
Notes Protect surfaces that are not to be treated from the effects of ASOCRET-HFF! When it comes to a cement-based screed, the carbide method moisture content may not exceed 2.0 CM%. The CM measurement must be completed in accordance with the current working instructions FBH-AD from the technical information "Interface coordination with heated floor constructions". Border, field, building separation and movement joints should be carried over to or installed at the designated location; suitable means (e.g. edge strips) should be used to detach them! Please observe BEB datasheet 5.2 "Information for joints in screeds". Due to the different absorption behaviours of the substrate, increased humidity, premature water loading and natural variations of raw materials, slight clouding (white colouring) may occur on the hardening surface. The coating must not be affected by water while it is binding. The effect of water from behind can lead to spalling in case of frost. The setting ASOCRET-HFF should be protected against rapid water removal (e.g. due to a high room temperature), direct solar radiation and draughts! Ideally, any potential skimming operation involving the use of ASOCRET-HFF should be carried out when the first layer is walkable, but still visibly damp (this can be discerned on the basis of the darker colour). If the first layer is dry, intermediate priming with epoxy resin primer, e. g. ASODUR®-SG3-superfast, is required. Exceeding the water quantity specified leads to lower strength and increased shrinkage. In addition, shrinkage cracks may occur, but these do not have a significant effect on the function of the product if the substrate adheres well Direct contact with metals such as copper, zinc, and aluminium must be avoided by means of a pore sealed primer. Pore-sealed priming is produced via 2 application steps using ASODUR®-GBM or ASODUR®-SG3-thix. The first application step is generously applied to the degreased and cleaned substrate. After a waiting time of approx. 3–6 hours, the second application step takes place and sprinkling with quartz sand with an aggregate of 0.2–0.7 mm. Consumption approx. 800–1000 g/m². If a mixing pump (e.g. PFT G4 or G5 or the like) is used, the mixing pump and hoses must be rinsed in case of interruptions of work! Note on choosing the right spiked roller: The length of the spikes must be as least 3 times the thickness of the layer applied. Supplier examples: www.polyplan-hamburg.de or www.maxinox.de. The temperature of the air, material and substrate may not fall below +5°C during application, and during the following week. Depending on the substrate, installation and ambient conditions, hairline cracks in the filler layer cannot be ruled out but do not reduce the functionality.
