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: Cement, aggregate, <br />high 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 <br />compressive strength: approx. 4.0/25 N/mm² <br />after 28 days 1) <br />Application/substrate <br />temperature: <br />+5° C to +25° C</p> <p>Cleaning tools: <br />in the fresh state with water <br />Consumption: approx. 1.5 kg/m² <br />at 1 mm thickness <br />Packaging: <br />25 kg bag <br />Storage: dry, min. 9 months in the original <br />unopened packaging. Use <br />opened packaging promptly. <br />1)</p> <p>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 in <br />accordance with DIN 1055. Separating layers, laitance <br />and similar must be mechanically removed by suitable <br />means e.g. surface abrasive blasting or scabbling. <br />Ensure there is no moisture pressure from the negative <br />side. Shrinkage processes must be largely at an end. <br />Remove hollow edges back to a sound core. Pre-treat <br />substrates by priming with ASO-Unigrund-GE. Suitable <br />floor substrates are concrete in accordance with <br />DIN 1045, heated and unheated cement-based screeds <br />in accordance with DIN 18560 and rapid setting <br />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”.</p> <p>1/3</p> <p>26/17</p> <p>Product preparation: <br />1. Prime the substrate with ASO-Unigrund-GE. <br />Cement-based substrates can also be pre-wetted <br />until matt damp. <br />2. Mix 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 <br />Add the water to a clean mixing bucket and <br />mechanically mix in the dry powder whilst stirring with <br />a drill and paddle (approx. 300 – 700 rpm) until <br />a homogenous, thixotropic, smooth and paste-like <br />smoothing compound is achieved. The mixing time <br />is approx. 3 – 5 minutes. Allow to stand for approx. <br />3 minutes, then re-mix. SOLOCRET-50 must be used <br />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 in <br />one coat, with isolated voids up to a thickness of <br />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 order <br />to remove surface irregularities and to leave a rough <br />finish, which ensures a good bond for subsequently <br />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 the <br />darker colour. Do not exceed a maximum thickness <br />of 50 mm. The air, material and substrate temperature <br />may not drop below +5° C during application and <br />within the next 24 hours.</p> <p>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 />• Clean, 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 />• Direct 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 <br />resin ASODUR-V360W (approx. 250 g/m²) with <br />a maximum of 5% water as necessary. After waiting <br />from 12 - 24 hours at +20° C, apply a second coat <br />of ASODUR-V360W (approx. 300 - 350 g/m²). <br />Blind the fresh second coat with 0.2 - 0.7 mm quartz <br />sand. After waiting for a further 12 - 16 hours continue <br />with the application of SOLOCRET-50 to a maximum <br />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.</p> <p>2/3</p> <p>26/17</p> <p>• 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.
