Furthermore, ASODUR-SG3-superfast can also be used on the following substrates: • Concrete and cement-based screeds subjected to moisture from the rear. • Concrete and cement-based screeds with increased residual moisture*.
Decant the material into a clean mixing bucket and mix through thoroughly once again. Notes: When using the product ensure that it is applied by flooding evenly over the prepared substrate. Irregularities lead to capillary active pores in the cured priming coat and promote the formation of bubbles especially osmosis bubbles. To ensure the priming coat has blocked the pores, apply a second coat. Pore blocking can also be ensured through the application of a second layer of a dense smoothing mortar. This smoothing mortar is produced from the priming resin with the addition of quartz sand. When adding aggregates (e.g. quartz sand) ensure that the aggregate is dry and is also at a temperature of approx. +15° C.
* Guidelines for the protection and repair of concrete constructions, part 2, paragraph 2.3.5 “concrete dampness”, 07.2002.
Substrate preparation is to be carried out with reference to DIN EN 14879-1:2005, 4.2 following. Dependent on the condition of the substrate to be treated, use suitable mechanical preparation methods, e.g. high pressure water blasting, scabbling, shot blasting, planing etc, with which a textured, open surface is achieved. (Repair large voids and cracks beforehand with a suitable product from the SCHOMBURG range).
Production of levelling / scratch coats: ASODUR-SG3-superfast: 1.0 part by weight Quartz sand: 1.0 part by weight (grade: e.g. 0.1–0.6 mm) ASO-FF approx. 2 % by weight to the mixed material
Appropriate to each particular substrate, the following criteria are also to be fulfilled: • Concrete quality: min. C 20/25 • Screed quality: min. EN 13813 CT-C25-F4 • Tensile adhesion strength: = 1.5 N/mm2
The quartz sand is mixed with the already mixed and decanted resin and hardener components. Ensure that the liquid and solid components are evenly blended together. Before application on vertical or steeply sloping surfaces it is recommended that with levelling/scratch coats ASO-FF is added.
Product preparation: Components A (resin) and B (hardener) are delivered at a pre-determined mixing ratio. Tip component B into component A. Ensure that the hardener drains completely from its container. Blending of both components together is to be carried out with a suitable mixer at approx. 300 rpm (e.g. drill with paddle). It is important to also stir from the sides and the bottom to ensure that the hardener is evenly dispersed. Stir until the mix is homogenous (free from streaks); mixing time approx. 3 minutes. The material temperature during mixing should be approx. +15° C. Do not use mixed material directly from the packaging!
Production of epoxy resin screeds: a.) T hickness: approx. 5–15 mm ASODUR-SG3-superfast: 3.0 part by weight Quartz sand: 25 parts by weight Grading: 0.06–1.5 mm ø Compressive strength: approx. 85 N/mm² Flexural strength: approx. 25 N/mm²

b.) Thickness: 9–40 mm ASODUR-SG3-superfast: 3.0 part by weight Quartz sand: 25 parts by weight Grading: 0.06–3.5 mm ø Compressive strength: approx. 85 N/mm² Flexural strength: approx. 25 N/mm² Place the predetermined quantity of quartz sand in a forced action mixer (e.g. type Zyklos or UEZ). Subsequently add the previously homogenously mixed resin and hardener components. Ensure that the liquid and solid components are evenly mixed together.
Consumption of fine smoothing compound: approx. 1.9 kg/m2/mm per thickness Epoxy resin screed: Firstly prime the floor with ASODUR-SG3-superfast. Consumption: approx. 450–700 g/m2 Apply the mixed screed to the freshly primed area at a minimum thickness of approx. 5mm, strike off with a lath and finish off mechanically smoothen (use a blade or plate power float). Consumption of prepared screed mix: approx. 2.0 kg/m2/mm per thickness
Production of the drainage mortar: ASODUR-SG3-superfast: 1.0 part by weight Quartz sand*: 25.0 parts by weight Grading: 1.0–4.0 mm ø Compressive strength: aprox. 20 N/mm² Flexural strength: approx. 5 N/mm²
Important advice: • As a rule SCHOMBURG products are supplied in working packs i.e. at a predetermined mixing ratio. With deliveries in large containers, part quantities will need to be weighed using scales. Always thoroughly stir the filled components and only then blend with the second component. This is to be carried out with a suitable rotary mixer e.g. Polyplan/Ronden mixing paddle or similar. In order to exclude mixing errors, decant into a clean mixing bucket and remix. The mixing speed should be 300 – 400 rpm. Ensure that no air is entrained. Higher speeds drag unnecessary air quantities into the product whilst lower speeds do not result in a good blend or require too long a mix time (pot life). The temperature of the components should be at a minimum of +15° C. This is also applicable to any fillers, e.g. sand, to be mixed in. The addition of any fillers is carried out after both liquids have been blended. Afterwards tip the completely mixed material immediately onto the prepared substrate and promptly thoroughly spread in accordance with the instructions in the technical data sheet. Always stir one component products before using. • Higher temperatures shorten the pot life. Lower temperatures increase the pot life and curing time. Material consumption is also increased at lower temperatures.

Method of application / consumption: Priming: Apply ASODUR-SG3-superfast in two coats. Consumption: approx. 300–500 g/m2 per coat. Priming for mineral-based levelling and smoothing mortars, e.g. for SOLOPLAN-30-PLUS: Apply ASODUR-SG3-superfast in two coats. Consumption: approx. 300–500 g/m² /coat Once the first application coat has dried, broadcast the fresh primer of the second application coat with quartz sand (particle size: 0.1–0.6 mm or 0.5–1.0 mm). Consumption: 1.0–1.5 kg/m² Levelling / scratch coat: Firstly prime the floor with ASODUR-SG3-superfast. Consumption: approx. 300–500 g/m2. The mixed smoothing compound is skim applied in one coat.

• Consumption quantities given are values determined by calculation without additions for surface roughness or absorption, levelling or residues in the containers. We recommend adding a calculated safety factor of 10% to the computed consumption quantities. • Applications that are not clearly explained in this technical data sheet may only be carried out after consultation with and written confirmation from the Technical Services Department of SCHOMBURG. • Cured product residues are to be disposed of under waste disposal classification AVV 150106.
• Colour: Minor colour variations due to different production plants and raw material fluctuations are unavoidable. This should be considered when applying coatings. Neighbouring sections should be completed with the same production units (see batch number on the packaging).The bond between the individual coats can be heavily impeded by the influence of moisture or contamination between successive applications. • The bond between the individual coats can be heavily impeded through the influence of moisture or contamination between successive applications. The substrate temperature must be a min. of <3° C above the dew point. • If there is a long time period between coatings or if areas need to be re-coated after a long time period, then the old surface must be well cleaned and thoroughly abraded, after which a completely new pore free sealing coat should be applied. It is not sufficient to simply overcoat. • Protect surface protective systems from moisture (e.g. rain) for approx. 4 – 6 hours after application. Dampness produces a white discolouration and/ or stickiness on the surface and can impede the cure. Discoloured and/or sticky surfaces should be taken off e.g. by abrading and renewed.
