Features & Benefits

• Uses:
  • Repair and levelling of reinforced concrete bearings for crane and bridge crane runways
  • Wear-resistant beds for machinery, beams, etc.
  • Rebuilding the corners of expansion joints in industrial flooring damaged by impact from trucks and forklifts, etc.
  • Filling holes and levelling off surfaces before the application of resinous systems exposed to chemical and mechanical stresses on industrial floors
  • Protective wear-resistant layers on foundation pads for depuration plants and concrete drain pipes
  • Wear-resistant protection of reinforced concrete elements such as ramps, silo beds, and concrete floors subject to heavy traffic
• Three-component mortar manufactured from a formula developed in the MAPEI Research & Development laboratories
• Composed of a fluid epoxy resin, a special hardener, and graded silica sand mineral filler that is ideal for preparing highly compact mortar
• Hardens without remarkable shrinkage to form a very strong product with particularly high resistance to wear and good resistance to aggressive chemical agents if saturated with Mapecoat I 24 or Mapefloor I 300 SL
• At +23°C Mapefloor EP19 is set for light foot traffic 6 hours after application and ready for vehicle traffic after 12 hours. Final curing occurs after 7 days
• Complies with the principles defined in EN 13813 “Screeds and materials for screeds - Material for screeds - Properties and requirements”, which specifies the requirements of materials for screeds used in the construction of internal floors.

Preparation & Application

Preparation of the substrate:

• The surface of concrete floors must be dry, clean and sound and have no crumbling or detached areas
• The compressive strength of the concrete used for the substrate must be at least 25 N/mm² and its tensile strength must be at least 1.5 N/mm²
• The strength of the substrate must also be suitable for its final use and the types of load to which it will be subjected
• The surface of the floor to be treated must be prepared with a suitable mechanical process (e.g. shot-blasting or grinding with a diamond disk), to remove all traces of dirt and cement laitance and crumbling or detached portions, and to make the surface slightly rough and absorbent
• Before applying the product remove all dust from the surface with a vacuum cleaner
• Metal surfaces should be sanded to bare metal before applying the product

Application of Primer SN:

• Just before applying Mapefloor EP19, impregnate the dry surface with Primer SN two-component epoxy primer, supplied in two pre-dosed containers
• Carefully blend component A and component B of Primer SN until an homogeneous is mixture is achieved

Preparing Mapefloor EP19:

• Pour Mapefloor EP19 components A and B into a bucket and mix for several minutes. Then add component C (powder) while mixing with a drill at low-speed and keep mixing to form an even, screed-mortar consistency

Applying the product:

• Trowel the Mapefloor EP19 onto the primer while the latter is still fresh, then tamp it and float finish with a metal trowel

Finishing coat:

• To reduce the porosity and the settling of dirt on the Mapefloor EP19 surface, one of the two procedures may be followed:
  • Saturate the surface with several coats of Mapecoat I 24
  • Apply a protective smoothing layer of Mapefloor I 300 SL mixed with 20% by weight of Quartz 0.25
  • Tools and clothing must be cleaned with ethyl alcohol while the product is still fresh

Consumption:

• Mapefloor EP19: 20 kg/m² per 1 cm of thickness
• Primer SN: 0.3-0.7 kg/m² according to the absorption of the substrate

Cleaning:

• Tools and clothing must be cleaned with ethyl alcohol while the product is still fresh

Limitations

• Do not dilute Mapefloor EP19 with solvent
• Do not apply Mapefloor EP19 on dusty or crumbling substrates
• Do not apply Mapefloor EP19 on substrates with oil or grease stains or stains in general
• Only apply Mapefloor EP19 on substrates treated with Primer SN and which have been prepared as specified
• Do not mix partial quantities of the components to avoid mixing errors; the product may not harden correctly
• Do not expose the mixed product to sources of heat
• Coatings made from Mapefloor EP19 may change colour or fade if exposed to sunlight but this has no effect on its performance characteristics
• The coating may also change colour if it comes into contact with aggressive chemicals. A change in colour, however, does not mean that it has been damaged by the chemical
• If rooms where the product is being used need to be warmed up do not use heaters that burn fossil fuels; the carbon dioxide and water vapour given off into the air will affect the shine of the finish and affect its appearance. Use electric heaters only
• Remove aggressive chemicals as soon as possible after they come into contact with Mapefloor EP19
• Use suitable specific cleaning equipment and detergent to clean the product, depending on the type of dirt or stain to be removed
• Protect the product from water for at least 24 hours after application
• The temperature of the substrate must be at least 3°C above dew-point
