2 Technical Data Requirements Requirements on the substrate: The concrete substrate must be load-bearing and free from characteristic or dissimilar separating substances as well as from corrosion-promoting components (e.g. chloride). Less solid layers and slurry accumulations must be removed. Damp the substrate in accordance with definition of the restoration guidelines Any exposed reinforcement steel must be prepared to SA 2 ½ in accordance with EN ISO Average tensile strength 1.5 N/mm² Smallest individual tensile strength value 1.0 N/mm 2 Preparations The substrate must be prepared by a suitable mechanical process such as blasting with solid abrasives, or high-pressure water jets (> 800 bar). Pores and shrinkage holes must be opened sufficiently. The edges of the spalling area must be bevelled under approx. 45 o. Temperature Material Preparation Minimum application temperature + 5 o C Maximum application temperature + 40 o C With approved dry spray machine The mixing procedure occurs in the spray nozzle. Consumption Type of application Approx. consumption Per mm of layer thickness (without rebound) 2.1 kg/m 2 Material consumption depends on the application, substrate and consistency, amongst other factors. The specified consumption values are only to be used as a guide. If required, precise consumption values should be determined on the actual site. Coating Procedure 1. Surface preparation 2. Corrosion protection with StoCrete CNP / StoDivers RustPruf (in case of exposed reinforcement) 3. Concrete substitute with Layer thickness : 6 50 mm Higher layer thickness is possible thanks to multi-layer work. Dry spraying, machine application with the dry spraying method Container: bagged and silo product 1. Surface preparation De-rust the exposed reinforcement steel up to purity grade SA 2 1/2 or 2. The de-rusted reinforcement steel must be free from dust and grease. The purity degree of the exposed reinforcement steel following substrate preparation: SA 2 in accordance with DIN EN ISO for restoration principle R SA 2½ in accordance with DIN EN ISO for restoration principle C Rev. no. 06 / SE / / 2/5

3 2. Corrosion protection Immediately after de-rusting the reinforcement steel, coat with StoCrete CNP / StoDivers RustPruf. Coat the reinforcement steels without gaps and uniformly using a coating brush. The concrete base must be sufficiently wetted before applying the product (first time about 24 hours beforehand). At the time of application, however, it must be dry to the point it only just appears slightly damp. 3. Concrete substitute with SMF technology (silo) Using the transfer hood, transfer the dry mortar to the dry spraying machine. Transfer hood available for : Mader Dry Spraying Machine WM 14, Control the material flow or the amount of material between the silo and the dry spray equipment via filling level sensor. When using for pre-moistening: Mixing shaft for pre-moistening as well as flow meter for controlling the quantity of water. Spraying procedure: Convey the dry mortar using a dry spraying machine with rotor or feed chamber and pocket wheel. Add water to the spraying nozzle for spraying. Compressor used should be capable of reaching at least 7 m³/min. output at 3 bar pressure. Spraying must be carried out by a tested nozzle guide. Normal nozzle distance: m 4. Surface finishing Double layer spraying of the SPCC is necessary for surface processing to avoid bonding flaws to the substrate. When spraying the second layer, the first layer should still be slightly damp. Contaminants such as dust, which impairs adhesive bonding, should be removed by taking suitable measures (e.g. oil-free compressed air). Particularly for spraying work in interior areas and where there is a risk of the remaining concrete surfaces in exterior areas being contaminated, which are to be reworked later by spraying, these surfaces must be covered with e.g sheets which are fixed on setting jigs. Care should be taken to ensure that any contaminant which impairs the adhesion bond arising from rebound or spray mist does not stick to the coated surfaces, or ensure that it is removed using suitable measures, such as sandblasting. The surface of the second layer must be troweled off over the setting jigs. Ensure that structural disorders and detachments from the substrate are avoided. If setting jigs have been anchored into the application areas to adhere to the layer thicknesses, they must be removed after completion of the spraying work. Parts remaining must end at least 5 cm below the sprayed concrete surface. The holes and recesses which arise should be closed as far as possible fresh on fresh with the same dry spray mortar. Rev. no. 06 / SE / / 3/5

4 Any construction joints that arise are to be reworked in accordance with DIN 1045, section (Issue July 88), if necessary with sandblasting using oil-free compressed air for soiling and wetting to produce a homogenous mortar layer on completion of the spray application. In general, leave with a rough spray surface (see DIN 18551), unless otherwise required. Rebound must be disposed of! After a certain curing time (depending on temperature, humidity, mortar thickness and substrate), the surface can be trowelled over setting jigs and rubbed off while ensuring that flaws in the joints and stripping of the substrate are avoided. Re-spray any gaps. Do not use any rebound for re-profiling! If a float-finished surface finish is required, can be reworked manually or by wet spray application with StoCrete TF 200 or StoCrete TF 204. Clean surface with a high-pressure cleaner (removal of fine spray dust). 5. Subsequent treatment Subsequent treatment procedure: a) cover with sheets or mats b) spray with water c) subsequent chemical treatment Under normal conditions, the time for subsequent treatment to be observed is at least 5 days. The corresponding standard DIN : , the B8 data sheet published by the Bauberatung Zement (cement construction advice) "Subsequent treatment of concrete" ( ) and ZTV-ING ( ) should be correspondingly observed. Note: Chemical treatment must only be carried out if subsequent work is compatible with this. Uniform colour shading of the mortar surface is not possible due to the application method. The film must not touch the surface of the mortar. A key part of subsequent treatment is to ensure adequate wetting of the concrete substrate prior to applying the mortar so that the substrate is water-saturated and the fresh mortar does not extract mixing water. The substrate must be "damp", as described in the section on substrate preparation, in accordance with the restoration guidelines.
