1 Rapid Application, Ultra Levelling, Cracking Free Screeding Method

2 Self-Levelling Screed vs Conventional Screed Feature and benefit of Self Levelling Screed Materials and Application Project Reference 2

3 Long setting time Site mixing, not constant quality High degree of shrinkage and high risk of crack High viscosity, not easy to flow, reduce application speed High alkalinity and decompose the vinyl sheet adhesive

4 vs Quality not consistent High shrinkage, high degree of cracks Slow application Slow drying, low curing time Low abrasion resistance High Quality Low shrinkage, no crack Fast application, up to 300 m 2 per hour Fast drying, foot traffic in 2 hrs High abrasion resistance, can be used for overlayment Low Volatile Organic Compound ( VOC ) 4

5 Underlayment i) Thick Layer To comply with specification Big hole repairing Leveling floor large variation ii) Thin Layer For vinyl sheet underlayment For epoxy coating underlayment For wood flooring underlayment Overlayment For human and light traffic: shopping mall, school, office, hospital Medium abrasion resistance For epoxy coating For heavy traffic : warehouse, car park For High abrasion resistance For epoxy coating, painting

14 低收缩率 Low shrinkage Complied with EN : 欧洲标准 : Within range 范围值 : 0.02% % (ie. 1m : 0.2mm to 0.7mm) 低收缩率能减少裂痕和剥落 Low shrinkage can reduce the chance of crack and debond 14

15 耐磨性能 欧洲标准 :EN (Rolling Wheel Abrasion) Complied with European Norm: EN (Rolling Wheel Abrasion) 高耐磨性能够提高地坪的使用年限 Abrasion resistance Higher abrasion resistance can provide a more durable floor. 高粘结强度 High adhesive strength Complied with European Norm: EN , SS HKHA Standard: HKHA MTS(2002/2004) Spec. Part D, Cl ) PH /PVC Lower ph reduce the chance of decomposition of carpet / PVC sheet adhesive 高粘结强度能够减少基面的剥离 Higher adhesive strength can reduce the change of debonding from substrate. 15

16 低碱性 Low alkalinity 自流平酸碱度 ph of self leveling compound: ph 10 一般水泥沙酸碱度 ph of cement-sand screed: ph14 自流平比一般水泥沙碱度少一千倍可减少乙烯基薄板地板粘结剂老化的机会从而减少基面的剥离 Alkalinity of self leveling compound 1000 times lower than that of cementsand. This remarkably lowers the chance of decay of vinyl sheet adhesive, thus, chance of delamination is greatly reduced. 16

32 When the concrete has high tolerance, should use E.MIX Easi Screed to level the floor. Reserve the concrete joint as a joint of the screed and SLC 32

33 First layer of E.MIX Primer should be diluted 1 5 with water and allow the primer to diffuse into the substrate When the first layer is dried, apply another layer of E.MIX Primer with 1 3 diluted, a film formed after drying 33

34 According to the concrete joint, use wood strips to separate the floor into different session Each session width is 5-8m, and leave as expansion joints X 34

35 According Pumping machine should be adjusted to right amount of water. It will vary with different type of machine and the age of the screw Pumping faster, the thinner the self-levelling screed Use the pumping speed to control the thickness. 35

Also avoid direct sunshine. During high wind The surface of Self-levelling screed is easy to set first and make the Selflevelling uneven 46

47 Before When the crack is not deep, can use V cut to remove it When it is deep use steel mesh to fix it and prevent the crack affect the SLC No treatment will allow the substrate crack continue on the surface E.MIX Rapifast Thin Thickness: 0-10mm Filling cavities and unevenness Extremely smoothening E.MIX Rapifast Thin After 47
