Remove any loose areas and laitance. Evenly <br />pre-wet absorbent substrates until saturated (avoid <br />puddle formation). <br />Product preparation: <br />Only use clean washed aggregates with a good <br />particle size distribution for producing the polymer <br />mortar. <br />The grain size is to be adjusted to suit the thickness <br />of the surface finish e.g.: <br />Up to 2 mm <br />diameter 0 – 0.5 mm <br />2 – 5 mm <br />diameter 0 – 1.0 mm <br />5 – 15 mm <br />diameter 0 – 2.0 mm or <br /> <br />0 – 4.0 mm <br />Above 15 mm <br />diameter 0 – 8.0 mm <br />Firstly mix dry, then add the ASOPLAST-MZ and water <br />solution and thoroughly mix for 2 minutes. Apply more <br />layers the greater the final thickness. As a rule apply wet <br />mortar to wet mortar. Never use the ASOPLAST-MZ and <br />water solution neat as if it dries too quickly a separating <br />film can form.</p> <p>Bonding coat / bonding slurry: <br />Note the following when rendering over difficult <br />substrates, waterproofing renders, waterproofing slurries, <br />patch repairs, levelling mortars, floor toppings, between <br />old and new concrete: <br />Mix solution: <br />ASOPLAST-MZ with water 1:1 to 1:3 <br />Dry mix: <br />cement and sand 1:3 <br />Grain size: <br />0 – 4 mm dependent on coating <br /> thickness <br />Consumption: 2.3 – 3.0 kg/m² and cm thickness</p> <p>Dry mix: <br />cement with sand 1:2 to 1:3 <br />Grain size: <br />0 up to max 8 mm, dependent on <br /> <br />thickness of layer <br />Consumption: 0.4 – 0.9 kg/m² dependent on <br /> <br />thickness of layer <br />The semi-dry mortar is applied wet in wet in layers from <br />15 – 30 mm, well compacted and rubbed down in <br />accordance with usual application specifications. Note <br />the position of shrinkage control joints and movement <br />joints.</p> <p>a) Splatterdash bond coat: <br />Prepare the mortar and spray it to a thickness of <br />4 – 5 mm. <br />Build-up further layers using conventional rendering <br />techniques following the usual specifications and <br />with pre-blended mortars following the manufacturer’s <br />directions. <br />b) Bonding slurry for bonded cement-based screeds: <br />Dilute ASOPLAST-MZ 1:1 with water. Then mix this <br />solution with the screed mortar to a slurry consistency. <br />Using a paint brush, broom or roofers broom work the <br />bonding coat produced into the dampened substrate <br />and then install the cement-based screed whilst the slurry <br />is still wet.</p> <p>Renders: <br />a) Standard lime-cement renders <br />Mix solution: <br />ASOPLAST-MZ with water 1:2 to 1:4 <br />Dry mix: <br />binder with sand 1:2.5 to 1:4 <br />Grain size: <br />0 - 4 – 0 - 8 mm <br />Consumption: 0.3 – 1.1 kg/m² and cm thickness <br />b) Rendering insulation panels <br />Mix solution: <br />ASOPLAST-MZ with water 1:2 <br />Dry mix: <br />binder with sand 1:3 <br />Grain size: <br />0 - 4 mm <br />Consumption: 0.7 – 1.0 kg/m² and cm thickness <br />The splatterdash coat is applied in accordance with <br />the instructions under the splatterdash section. The base <br />coat is applied to the hardened splatterdash coat to <br />usual rendering regulations. ASOPLAST-MZ is added <br />to the base coat where better adhesion, increased <br />flexibility, reduced tendency for shrinkage cracks and <br />reduced permeability to water is required.</p> <p>Levelling, patch repair and packing mortar: <br />Mix solution: <br />ASOPLAST-MZ with water <br /> <br />For thicknesses below 10 mm 1:3 <br /> <br />For thicknesses above 10 mm 1:5 <br />Dry mix: <br />cement and sand 1:2 to 1:4 <br />Greater chemical resistance, especially against urea, <br />ammonia and dilute alkalis, is achieved with a fatter mix <br />solution e.g. ASOPLAST-MZ: water 1:2. <br />Grain size: <br />0 – 4 mm dependent on thickness <br /> of layer <br />Consumption: 0.7 – 1.5 kg/m² and cm thickness <br />Apply the stiff plastic mortar on to the well pre-wetted <br />substrate. A bonding coat is necessary (see above) on <br />heavy duty areas as well as on very smooth substrates. <br />Floor toppings, wear resistant toppings in hydraulic <br />engineering construction, sub-bases: <br />Mix solution: <br />ASOPLAST-MZ with water <br /> <br />For heavy duty use 1:1 to 1:2 <br /> <br />For normal use 1:2 to 1:4</p> <p>Smoothing coat and levelling exposed concrete: <br />Mix solution: <br />ASOPLAST-MZ with water 1:3 to 1:5 <br />Dry mix: <br />cement with sand 1:3 <br />Grain size: <br />0 – 1 mm <br />Consumption: 0.7 – 1.3 kg/m² and cm thickness <br />Thoroughly clean and pre-wet the substrate. Prepare the <br />mix previously described to a trowelable consistency. <br />Firstly prepare the bonding coat and thoroughly brush <br />in with a brush or broom. Then immediately apply the <br />mortar described above into the wet bonding coat using <br />a trowel or rubber float, rub up with a hand float and <br />smooth with a steel trowel.</p> <p>Special mortar: <br />Mix solution: <br />ASOPLAST-MZ with water 1:3 to 1:5 <br />Dry mix: <br />cement with sand 1:2 to 1:3 <br />Grain size: <br />0 – 8 mm <br />Consumption: 0.6 – 1.1 kg/m² and cm thickness <br />For bridging over construction joints between concrete <br />sections prepare the above mix to a stiff consistency and <br />apply to the clean, pre-wetted substrate at a thickness <br />up to 5 mm immediately before installing concrete. <br />When using shuttering, this must be sealed. The <br />construction joint so produced is to be carefully covered <br />in concrete and compacted as usual. <br />Adhesive, grout and coved fillet mortar: <br />a) For rigid joints in concrete and masonry construction. <br />Mix solution: <br />ASOPLAST-MZ with water 1:2 to 1:4 <br />Dry mix: <br />cement with sand 1:2 to 1:3 <br />Grain size: <br />0 – 2 with increased fines up to <br /> 0.2 mm <br />Consumption: 0.7 – 1.9 kg/m² and cm thickness <br />Prepare the mortar to a paste consistency and push <br />into the joints with a trowel, gauging trowel or pointing <br />trowel. <br />b) Bonding insulation panels and lightweight <br />construction boards <br />Mix solution: <br />ASOPLAST-MZ with water 1:1 <br />Dry mix: <br />cement with sand 1:3 <br />Grain size: <br />0 – 2 mm <br />Consumption: 1.4 – 1.9 kg/m² and cm thickness <br />Apply ‘blobs’ of the plastic mortar or a full bed with <br />a trowel or notched trowel and push in the boards/ <br />panels. <br />Addition to coloured lime and cement coatings: <br />Mix solution: <br />ASOPLAST-MZ with water 1:1 <br />Consumption: approx. 0.1 to 0.2 kg/m² <br />Use the above mix solution as a replacement for water. <br />This imparts increased adhesion and resistance to <br />wiping as well as improved weathering to the coating. <br />Finishing for all types of application: <br />During the first 5 days, protect renders, floor toppings, <br />patching and levelling mortars etc from drying out too <br />quickly, due to wind and sunshine, by covering with <br />polythene or repeatedly wetting. Also protect from frost.</p> <p>Evaporation protection for concrete: <br />After diluting (1 part ASOPLAST-MZ – 2 parts water) <br />apply by spray or brush. Application should take place <br />as soon as the setting process has commenced but the <br />surface is free from water. <br />Material consumption: 50 – 70 g/m² undiluted <br /> ASOPLAST-MZ <br />Advice: <br />• Always mechanically mix ASOPLAST-MZ (not longer <br />than 2 minutes). <br />• Neat ASOPLAST-MZ without cement and sand is not <br />suitable as a bonding coat as a separating layer can <br />form due to premature film formation. <br />• ASOPLAST-MZ solutions diluted at a ratio greater <br />than 1:5 (MZ:water) provide the mortar with too little <br />polymer so that the mortar properties are scarcely <br />improved. <br />•ASOPLAST-MZ is not resistant to continuous contact <br />with petrol and organic solvents (use ASODUR <br />mortars). <br />• When using ASOPLAST-MZ, trade application <br />regulations must be followed the same as if <br />conventional mortars were being applied. <br />•Use clean sand with a suitable particle size <br />distribution (grading). <br />• Always use the least amount of mix water possible. <br />• When applying multi-layers, always apply wet in wet. <br />• Mortar that has already started to stiffen should not be <br />re-lifed by adding more water or fresh mortar as there <br />is a risk of inadequate strength development. <br />•Protect areas to which ASOPLAST-MZ will not be <br />applied. <br />• Wash off splashes immediately. <br />• Protect from rapid drying. <br />• Protect from wind and extremes of temperature. <br />Please observe a current valid EU Health & <br />Safety Data Sheet <br />GISCODE: D1</p> <p>This technical data sheet is a translation from the German language version and does not consider local building codes or legal requirements.
