The substrate must be clean, dry and free of all contaminants such as dirt, oil, grease, coatings, surface treatments, etc. If in doubt, apply a test area first. 3 ® SikaCor VEMY 3/5 Substrate Preparation Concrete substrates must be prepared mechanically using abrasive blast cleaning or grinding equipment to remove cement laitance and achieve an open textured surface. Weak concrete must be removed and surface defects such as blowholes and voids must be fully exposed. Repairs to the substrate, filling of blowholes/voids and surface levelling must be ® ® ® carried out using appropriate products from the Sikafloor , Sikadur and Sikagard range of materials. The concrete or screed substrate has to be primed or levelled in order to achieve an even surface. High spots must be removed by e.g. grinding. All dust, loose and friable material must be completely removed from all surfaces before application of the product, preferably by brush and/or vacuum. Application Conditions / Limitations Substrate Temperature +5°C min. / +30°C max. Ambient Temperature +5°C min. / +30°C max. Substrate Moisture Content < 4% pbw moisture content. ® Test method: Sika Tramex meter, CM - measurement or Oven-dry-method. No rising moisture according to ASTM (Polyethylene-sheet). Relative Air Humidity 80% r.h. max. Dew Point Beware of condensation! The substrate and uncured floor must be at least +3°C above the dew point to reduce the risk of condensation or blooming on the floor finish. Application Instructions Mixing Laminate layer and top coat Part A : Part B = 100 : 1.5 – 2.0 (by weight) Mixing Time Prior to mixing, stir part A mechanically. When all of part B has been added to part A, mix continuously for 1 – 2 minutes until a uniform mix has been achieved. To ensure thorough mixing pour materials into another container and mix again to achieve a consistent mix. Over mixing must be avoided to minimise air entrainment. ® Mixing Tools SikaCor VEMY must be thoroughly mixed using a low speed electric stirrer (300 400 rpm) or other suitable equipment. Application Method / Tools Prior to application, confirm substrate moisture content, r.h. and dew point. ® ® If > 4% pbw moisture content, Sikafloor EpoCem may be applied as a T.M.B. (temporary moisture barrier) system. Laminate Layer ® SikaCor VEMY is applied as primer and let it cure. st Place a 1 layer of Sika Reemat CSM-300 onto the freshly applied coat and compact with roller to allow soaking. nd Place 2 layer of Sika Reemat CSM-300 in the same way. Place Sika Reemat SM-30 and compact it with laminate roller. Make sure that trapped air is released. All application is done wet in wet. Important: 5cm overlapping is required for both layers of Sika reemats. The nd st overlapping of 2 layer of glass matt should be positioned 30cm away from the 1 layer. Cleaning of Tools Clean all tools and application equipment with acetone immediately after use. Hardened and/or cured material can only be removed mechanically. Attention: Acetone is a flammable liquid, please handle with care, use all equipment for your personal protection required. 4 ® SikaCor VEMY 4/5 Notes on Application / Limitations ® Do not apply SikaCor VEMY on substrates with rising moisture. ® Freshly applied SikaCor VEMY should be protected from damp, condensation and water for at least 24 hours. During application in closed rooms, pits and shafts etc., sufficient ventilation must be provided. Keep away open light, including welding. In poorly lid rooms only electric safety lamps are permitted. The installed ventilation equipment must be spark-proof. Curing Details Curing and operation o time (+20 C): Overcoatable: after 2 hours (top coat) Foot traffic: after 4 hours Fully cured: after 2 days Construction Note: Times are approximate and will be effected by changing ambient conditions.
