For precise information, see the additional Technical Information No. 43. <br />The discharge dimension must be continuously checked with mechanical application. This is done using a PFT consistency test socket. The <br />discharge dimension must be determined on a moistened glass plate and should be approx. 60 cm.</p> <p>Suitable substrate <br />Concrete substates in accordance with DIN 1045 <br />Heated and unheated cement-based screeds in accordance with DIN EN 13813 <br />Rapid cement screeds</p> <p>Preparing the substrate <br />Requirement for substrate <br />1. Dry <br />2. Firm <br />3. Free of adhesion inhibiting substances <br />4. The substrate must correspond to the load-bearing capacities in accordance with DIN 1055. <br />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).</p> <p>Preparing the surface <br />1. Remove oil wax residues using ASO-R008. <br />2. Prime cementitious substrates with a moisture content of < 4% and water vapour resistance factor of < 0.6 g/m² h with AQUAFIN-PRIMER. <br />3. In substrates with rear-sides or increased moisture load in exterior areas, with old, firmly adhering epoxy resin coatings or increased mechanical <br />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. <br />After the reaction has taken place (approx. 16 hrs), brush off any excess quartz sand. <br />4. Old, firmly adhered, load-bearing reaction resin coatings must be ground before coating with ASOCRET-HFF and primed with ASODUR-SG2 or <br />ASODUR-SG3-thix. <br />5. The temperature of the air, material and substrate may not fall below +5°C during application, and during the following week. <br />6. In the case of substrates damaged by de-icing salt, the substrate must be removed down to the neutral area using suitable measures. <br />7. Fill deeper damaged areas and holes using ASOCRET BIS system, cracks must be filled with ASODUR-GH-S. <br />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 <br />prevent straining of the material. Existing joints in the substrate must be brought through, the flow of material in these joints must be prevented <br />using suitable measures.</p> <p>Application <br />Mixing <br />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. <br />2. In between, scrape the unmixed material from the side walls with a trowel and feed it to the mixing process. <br />3. The mixing time is ca. 3 - 5 minutes. <br />4. After a settling period of ca. 2 minutes, thoroughly homogenise the compound again.</p> <p>SCHOMBURG GmbH & Co. KG · Aquafinstr. 2–8 · D-32760 Detmold (Germany) · Tel. +49-5231-953-00 · Fax +49-5231- 953-333 · schomburg.com <br />3/5</p> <p>01/04/2025</p> <p>Technical data sheet <br />ASOCRET-HFF <br />Application <br />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 <br />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 <br />encourage it to flow. <br />2. Coloured seals can be created with ASODUR-V360W. The surface coated with ASOCRET-HFF must be checked beforehand to ascertain <br />whether it needs to be prepared by grinding, etc. <br />3. Applications in exterior areas or surfaces with increased moisture pressure, coating with ASODUR-B351 is required. <br />4. After removing the protruding edging strips, connecting joints must be sealed with INDUFLEX-PU. <br />5. The coating must be protected against weathering influences, e.g. strong solar radiation, wind loads etc., and against mechanical damage or <br />loads using suitable measures in the first 24 hours. <br />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 <br />vehicles. With vehicles fitted with polyamide tyres, there is a risk of surface damage and they should therefore be ruled out.</p> <p>Cleaning tools <br />Clean tools thoroughly with water after use.</p> <p>Storage conditions <br />Storage <br />Store in a cool and dry place. Min. 12 months in the original canister. Promptly use opened container.</p> <p>Notes <br />Protect surfaces that are not to be treated from the effects of ASOCRET-HFF! <br />When it comes to a cement-based screed, the carbide method moisture content may not exceed 2.0 CM%. The CM measurement must be <br />completed in accordance with the current working instructions FBH-AD from the technical information "Interface coordination with heated <br />floor constructions". <br />Border, field, building separation and movement joints should be carried over to or installed at the designated location; suitable means (e.g. <br />edge strips) should be used to detach them! Please observe BEB datasheet 5.2 "Information for joints in screeds". <br />Due to the different absorption behaviours of the substrate, increased humidity, premature water loading and natural variations of raw <br />materials, slight clouding (white colouring) may occur on the hardening surface. <br />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. <br />The setting ASOCRET-HFF should be protected against rapid water removal (e.g. due to a high room temperature), direct solar radiation <br />and draughts! <br />Ideally, any potential skimming operation involving the use of ASOCRET-HFF should be carried out when the first layer is walkable, but still <br />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. <br />g. ASODUR®-SG3-superfast, is required. <br />Exceeding the water quantity specified leads to lower strength and increased shrinkage. In addition, shrinkage cracks may occur, but these <br />do not have a significant effect on the function of the product if the substrate adheres well <br />Direct contact with metals such as copper, zinc, and aluminium must be avoided by means of a pore sealed primer. Pore-sealed priming is <br />produced via 2 application steps using ASODUR®-GBM or ASODUR®-SG3-thix. The first application step is generously applied to the <br />degreased and cleaned substrate. After a waiting time of approx. 3–6 hours, the second application step takes place and sprinkling with <br />quartz sand with an aggregate of 0.2–0.7 mm. Consumption approx. 800–1000 g/m². <br />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! <br />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 <br />examples: www.polyplan-hamburg.de or www.maxinox.de. <br />The temperature of the air, material and substrate may not fall below +5°C during application, and during the following week. <br />Depending on the substrate, installation and ambient conditions, hairline cracks in the filler layer cannot be ruled out but do not reduce the <br />functionality.</p> <p>Observe applicable safety data sheet!</p> <p>SCHOMBURG GmbH & Co.
