Remove oil wax residues using ASO-R008. <br />2. Prime cementitious substrates with a moisture content of < 4% and water vapour resistance of < 0.6 g/m² h with ASO-Unigrund. <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-superfast and then sprinkle with plenty of quartz sand with an aggregate grain of 0.5–1.0 <br />mm. 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-superfast. <br />5. The temperature of the air, material and substrate may not fall short of +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>Usage <br />Mixing <br />1. Put 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.</p> <p>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 relevant layer thickness in an application step, whereby the still liquid layer is de-aerated or stimulated to <br />flow with a spiked roller, buffing rod or another suitable tool. <br />2. For transparent protection of the surface against dirt and liquids, the dried surface can be impregnated with REMISIL-SI after a waiting time of ≥ 6 <br />hours. <br />3. 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 />4. Applications in exterrior areas or surfaces with increased moisture pressure, coating with ASODUR-B351 is required. <br />5. After removing the protruding edging strips, connecting joints must be sealed with INDUFLEX-PU. <br />6. 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 />7. 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 canister.</p> <p>SCHOMBURG GmbH & Co.

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-superfast. 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 short of +5°C during application, and during the following week.</p> <p>Observe applicable safety data sheet!</p> <p>The rights of the buyer with regard to the quality of our materials are based on our terms and conditions of sale and delivery.
