Pour approximately half into a clean mixing container, then add part B slowly while mixing. Add the remainder of part A and mechanically mix for approximately 3 minutes until uniform and lump-free. Use a forced-action mixer or suitable drill mixing equipment.\u003c\/li\u003e\n\u003cli\u003eFor standard slurry application, mix A:B at 1:4 by weight without added water. Apply by stiff brush or suitable spray equipment, working the first coat in one direction.\u003c\/li\u003e\n\u003cli\u003eOnce the first coat has hardened, apply the second brush coat crosswise to the first. Keep within the specified layer thickness of 0.75–2mm.\u003c\/li\u003e\n\u003cli\u003eFor trowel-applied mortar, Sika specifies a 10% reduction in part A, approximately A:B 1:4.5 by weight. Apply the second coat once the first has hardened. For pores and blowholes, trowel tightly into the defects.\u003c\/li\u003e\n\u003cli\u003eApply at air and substrate temperatures of +8°C to +35°C.
