MasterEmaco S 488 PG | Warehouse floor refurbishment

Specifications

Surface preparation before laying the Emaco mortar

• It should be ensured that the surfaces to be repaired are sound, clean, and dry;

• The surface must not be weakened by excessive smoothing or insufficient moisture care;

• The surface must not be covered with frost, membrane-forming materials, waterproofing coatings , must not contain oil residues, cement laitance, crushed particles of the base, dust and other elements that can reduce adhesion;

• If there are leaks, they should be repaired with appropriate materials;

• The edges of the defective area should be contoured with a diamond tool, perpendicular to the surface to a depth of at least 10 mm;

• Remove broken concrete using a light hammer drill, needle gun or water sandblaster;

• It is necessary that the surface be rough, with grooves 5 mm high, to ensure good adhesion of the base and the Emako repair mortar;

• This operation is very important, because for the application of MasterEmaco S 488PG, a well- prepared rough surface is required;

• In addition, it is necessary to clean the fittings from rust, if necessary, install additional fittings;

• If the repaired structure is operated in environments aggressive to concrete and steel, it is recommended to treat the reinforcement with MasterEmaco P300 material; 

• The concrete surface should be thoroughly moistened, before applying the Emaco repair mixture , remove excess water.

Preparation of a solution of dry mix Emako

• Pour the required amount of water, using a measuring container, into a clean mixing container;

• Slowly add Emako dry mix;

• Mix with a low-speed mixer, at a speed of 300-600 rpm, for 4 minutes until a homogeneous repair mixture is obtained, without lumps;

• After 4 minutes, stir the prepared repair composition again for 30 seconds.

How to use EMACO pourable repair compound

• The prepared bulk solution is applied with a steel spatula;

• The thickness of applying the repair mixture Emako is 10-40 mm;

• If a thicker layer is required, we recommend applying the repair compound in several stages with an interval between layers of 24 hours;

• When applied with a layer of more than 40 mm, additional reinforcement is required;

• We also recommend introducing additional crushed stone of a fine fraction to obtain Emako microconcrete ;

• For detailed recommendations, please contact  FLOORTOP;

• You should wait until the repair compound begins to set;

• Then, water is sprayed onto the applied solution, and the surface is given its final look, using a steel or wooden float;

• Exposed surfaces should be protected for 24-48 hours from rain, wind, harsh weather, with a damp burlap or water, or a MasterKure membraine-forming spray membrane.

Consumption  of bulk mixture Emako

19.4 kg/m2 powder product, per 10 mm layer thickness.

Precautionary measures

• The repair mortar at +20°C must be used up within 30 minutes. At a temperature of +30°C, this period is reduced;

• For outdoor applications, surfaces should be protected from sun, wind, rain or frost for 24 hours after application;

• The terms of work and hardening of cement-based systems depend on the ambient and surface temperature, relative air humidity;

• At low temperatures, hydration slows down, which prolongs the working time with the mixture and the setting time;

• High temperatures accelerate hydration, resulting in reduced working time with the mixture and setting time;

• For complete curing of the material, the ambient and surface temperatures must not fall below the specified minimum limits;

• Do not use the mixture as a screed or surface hardener on a large surface.

Cleaning tools

• After use, used tools and equipment should be washed with water;

• MasterEmaco S 488 PG after hardening can be cleaned from the surface only mechanically.
