SIKA SikaTop-111 self-levelling mortar - 37.5 kg - Grey, is used as a waterproofing coating to waterproof concrete floors in structures such as: underground premises, tanks, basins and even cold rooms. Advantages : Can be put in contact with water intended for human consumption Impermeable to water under pressure or counter-pressure Easy and quick to apply Hardens quickly Excellent mechanical resistance Excellent adhesion to most substrates (concrete, mortar, stone, brick, etc.). Insensitive to freeze/thaw cycles and de-icing salts Features : Packaging : Kit of 37,5 Kg including : Component A (emulsion resin) : 5 liters can. Component B (cement in special fillers): 32.5 kg bag. Inspection/Colour: Dark Grey Storage condition : Component A fears freezing Component B fears moisture Shelf life: An unopened kit stored between +10C and +30C will keep for 1 year. Density: approx. 2.2 kg/l Packaging : x1 Hydraulic Mortar Delivered in its original packaging Tips : QUALITY OF THE SUPPORT / PRE-TREATMENT The substrates must have the following minimum mechanical strengths : Cohesion of at least 1 MPa in direct traction Compressive strength of at least 25 MPa The surface must be clean, sound and have undergone a suitable preparation of its surface to remove any loose or poorly adherent parts. In particular, it must be free of traces of oil, grease, laitance, curing products and any substance that may impair adhesion. During application, the substrate must be saturated with water. To do this, water it abundantly the day before and moisten it again just before application. Make sure, however, that no puddles remain on the surface that could impair the adhesion or aesthetics of the coating.
