SOLOCRET-50 is suitable for exterior and wet duty <br />areas when an appropriate SCHOMBURG bonded <br />waterproof membrane is installed. <br />Technical Data: <br />Basis: <br />Cement, aggregate, high <br /> quality additives <br />Colour: Grey <br />Bulk density: <br />approx. 1.2 kg/dm3 <br />Pot life: <br />approx. 30 mins 1) <br />Overcoat: <br />after approx. 3 – 4 hrs 1) <br />Flexural and compressive <br />strength: <br />approx. 4.0/25 N/mm² <br /> after 28 days <br />Application/substrate <br />temperature: <br />+5° C to +25° C <br />Cleaning tools: <br />in the fresh state with water <br />Consumption: <br />approx. 1.5 kg/m² at 1 mm <br /> thickness <br />Packaging: <br />25 kg bag</p> <p>Storage: <br />dry, min. 6 months in <br /> <br />the original unopened <br /> <br />packaging. Use opened <br /> packaging promptly. <br />* Values are valid at +23° C and 50% relative humidity</p> <p>Substrate preparation: <br />The mineral-based substrate must be load-bearing, <br />solid, have a good key and be free from materials <br />acting as separating layers. The load-bearing capacity <br />of the substrate must be appropriate to take loads <br />in accordance with DIN 1055. Separating layers, <br />laitance and similar must be mechanically removed <br />by suitable means e.g. surface abrasive blasting or <br />scabbling. Ensure there is no moisture pressure from the <br />negative side. Shrinkage processes must be largely at <br />an end. Remove hollow edges back to a sound core. <br />Pre-treat substrates by priming with ASO-Unigrund-GE. <br />Suitable floor substrates are concrete in accordance <br />with DIN 1045, heated and unheated cement-based <br />screeds in accordance with DIN 18560 and rapid <br />setting cement-based screeds (e.g. ASO-EZ6-Plus). <br />Before applying SOLOCRET-50, the readiness of a <br />floor substrate to receive finishes is to be determined by <br />moisture measurements with a carbide hygrometer. The <br />CM moisture content may not exceed: <br />• Cement-based screeds (CT) ≤ 2.0 CM% for screeds <br />on insulation or separating layers <br />• Calcium sulphate screeds (CA) without underfloor <br />heating ≤ 0.5 CM% <br />• Calcium sulphate screeds (CA) with underfloor <br />heating ≤ 0.3 CM% <br />The CM measurements are to be carried out following <br />the current FBH-AD work instructions taken from the <br />technical information “coordination of cut out points in <br />heated floor constructions”. <br />Product preparation: <br />1. P rime the substrate with ASO-Unigrund-GE. <br />Cement-based substrates can also be pre-wetted <br />until matt damp. <br />2. M <br /> ix SOLOCRET-50 with clean water in a clean <br />mixing bucket until homogenous. <br />Mixing ratio: <br />Approx. 4 – 4.5 litres water : 25 kg SOLOCRET-50</p> <p>1/3</p> <p>49/15</p> <p>Add the water to a clean mixing bucket and <br />mechanically mix in the dry powder whilst stirring <br />with a drill and paddle (approx. 300 – 700 rpm) <br />until a homogenous, thixotropic, smooth and pastelike smoothing compound is achieved. The mixing <br />time is approx. 3 – 5 minutes. Allow to stand for <br />approx. 3 minutes, then re-mix. SOLOCRET-50 must <br />be used within 30 minutes at +20° C. <br />3. Produce a scratch coat and then trowel apply <br />SOLOCRET-50 and evenly spread with a suitable <br />tool (plasterer’s darby) within the working time. <br />SOLOCRET-50 can be applied up to 50 mm thick <br />in one coat, with isolated voids up to a thickness <br />of 100 mm. If desired it can be smoothed off after <br />30 minutes. <br />4. After approx. 60 – 80 minutes. Dependent on the <br />substrate, ambient conditions and thickness, the <br />material can be smoothened with a grid float in <br />order to remove surface irregularities and to leave <br />a rough finish, which ensures a good bond for <br />subsequently applied tile adhesives. <br />5. Where it is necessary to apply another coat of <br />SOLOCRET-50, this is best carried out when the <br />first coat is hard but still damp as recognised by <br />the darker colour. Do not exceed a maximum <br />thickness of 50 mm. The air, material and substrate <br />temperature may not drop below +5° C during <br />application and within the next 24 hours. <br />Important advice: <br />• Do not use in areas with water under pressure! <br />• Instead of ASO-Unigrund-GE, ASO-Unigrund-K (diluted <br />1:3 to 1:4 with water) or ASO-Unigrund-S (neat up to <br />1:1 dependent on the substrate) can be used. <br />•C <br /> lean, abrade and prime old, well bonded ceramic <br />finishes with ASO-Unigrund-S and allow to harden. <br />Subsequently trowel over with a maximum of 20 mm <br />SOLOCRET-50. <br />•D <br /> irect contact between cement-based tile mortars <br />and magnesite screeds leads to the destruction of <br />the magnesite screed through a chemical reaction. <br />Moisture penetration from the rear must be eliminated <br />with appropriate measures. Mechanically roughen <br />the magnesite screed and prime with the epoxy</p> <p>•</p> <p>• <br />• <br />• <br />•</p> <p>• <br />• <br />•</p> <p>2/3</p> <p>resin ASODUR-V360W (approx. 250 g/m²) with a <br />maximum of 5% water as necessary. After waiting <br />from 12 - 24 hours at +20° C, apply a second <br />coat of ASODUR-V360W (approx. 300 - 350 g/ <br />m²). Blind the fresh second coat with 0.2 - 0.7 mm <br />quartz sand. After waiting for a further 12 - 16 hours <br />continue with the application of SOLOCRET-50 to a <br />maximum 50 mm thickness. <br />With calcium sulphate based screeds, at the time of <br />levelling with SOLOCRET-50 the CM moisture content <br />must not exceed 0.5% without underfloor heating <br />and 0.3% with underfloor heating. Thoroughly prime <br />with ASODUR-V360W and subsequently broadcast <br />with 0.5 - 1.0 mm quartz sand. After waiting for a <br />further 12 - 16 hours continue with the application <br />of SOLOCRET-50 to a maximum 50 mm thickness. <br />Prevent further moisture ingress. <br />Perimeter, bay, structural and general movement joints <br />are to be brought through or inserted as designed. <br />Stop with a suitable material e.g. edge strips. <br />Very porous substrates result in greater material <br />consumption. <br />High temperatures accelerate, lower temperatures <br />slow down the setting process. <br />Do not attempt to re-life SOLOCRET-50 that has <br />already started to stiffen, by adding more water or <br />fresh mortar as there is a risk of inadequate strength <br />development. <br />Protect areas not being treated with SOLOCRET-50 <br />from its effects. <br />Observe a valid EU Health & Safety data sheet. <br />Follow the relevant current regulations.
