This is Method Statement for Work using Sika Monotop System. Scope: A simple step by step guide to preparing and applying Sika Concrete Repair Systems. Advantages: • Easy to use (only to be mixed with water) • Can be applied from different thickness • Good adhesion • Very smooth surface finish • The finished mortar is ready to be painted if required Substrate preparation: Mark out all of the defective areas of concrete to be removed. The concrete surfaces to be repaired must be free from dust, loose or friable materials, surface contaminants and any other materials which could reduce the bond of the repair materials.

In order to achieve these requirements, all delaminated, weak, damaged and deteriorated concrete and where necessary sound concrete, shall be removed by suitable mechanical tools. Polaris booster pump pb4-60 wiring diagram. Remove concrete minimum 15 mm behind main bars. Bonding agent and anti corrosive layer: Sika Monotop 610 will be applied as treatment for preventing corrosion and as a bonding bridge for concrete repair Sika Monotop products. Repair application by hand: Sika Monotop R: from 5 to 30 mm application on vertical layer.

* Concrete treatment according to method statement of Sikadur® Combiflex SG system. * * The bonding surface of the SikaProof® A membrane has to be. Fully bonded to the precast concrete element.

Sika Monotop 615 HB: from 5 to 60 mm application on vertical layer. (20 mm overhead) • Wet the substrate • Wipe away excess water • Mixing of Sika Monotop repair mortar • Press firmly the repair mortar into the repair area using a trowel • Profile surface and finish with trowel • Finish surface with wooden or PVC trowel for best results.

• Do not spray additional water over the surface! • Protect / Cure application from wind, rain, sun by using a plastic sheet or wet jute/hessian.
