SikaEmaco® S 488 (formerly known as MasterEmaco® S 488) - Shrinkage compensated, fiber reinforced, thixotropic repair mortar 

How does MasterEmaco S 488 work?

MasterEmaco S 488 is a cementitious prebagged ready-to-use structural repair mortar in powder form. When mixed with the correct amount of water, it produces a thixotropic, high strength repair mortar, reinforced with acrylic fibres. It possesses excellent bond characteristics to steel reinforcement and to concrete.

MasterEmaco S 488 mortar is shrinkage compensated. It has low permeability and is extremely durable. MasterEmaco S 488 contains no metallic aggregate and is chloride free.

MasterEmaco S 488 is formulated for sprayed or trowelled applications, in thicknesses up to 50mm in one layer by hand application.
