Technical Characteristics

After mixing MapeWrap 11 component A or MapeWrap 12 component A with their relative hardener (component B), they become a thixotropic paste, easy to apply both on vertical surfaces and on soffits.

The two products differ from each other only for the workability time: MapeWrap 11 is suitable for applications at temperatures between +5°C and +23°C, while MapeWrap 12 is recommended in hot climates.

MapeWrap 11 and MapeWrap 12 harden without shrinkage, becoming extremely tacky and mechanically strong. MapeWrap 11 and MapeWrap 12 respond to the principles defined in EN 1504-9 (“Products and systems for protecting and repairing concrete structures: definitions, requirements, quality control and conformity evaluation. General principles for the use and application of systems”), and the minimum requirements for EN 1504-4 (“Structural bonding”).

Recommendations

• MapeWrap 11 and MapeWrap 12 must not be used on wet surfaces
• MapeWrap 11 and MapeWrap 12 must not be used on dirty or crumbling surfaces

Application Procedure

Preparing the substrate

Treat the substrate with MapeWrap Primer 1 before applying MapeWrap 11 or MapeWrap 12.

Preparing the mixes

The two components of MapeWrap 11 and MapeWrap 12 must be mixed together. Pour component B (white) into component A (grey) and mix with a slow speed drill fitted with a stirrer until the resin is completely homogeneous (completely grey). The products come already pre-dosed therefore do not use partial quantities to avoid the risk of accidental ratio errors that could prevent MapeWrap 11 and MapeWrap 12 from hardening. If only partial quantities an required, use a high-precision electronic scale.

Applying the mixes

MapeWrap 11 and MapeWrap 12 can be applied on concrete, stone, brick or metal with a flat trowel after the substrate has been primed with MapeWrap Primer 1.

In order to obtain good levelling, it is recommended to let the product penetrate well into particularly uneven areas.

Apply, with a notched trowel, approximately a 1 mm layer of MapeWrap 11 or MapeWrap 12, depending on the temperature, over the still fresh MapeWrap Primer 1. Use a flat trowel to completely level even the most uneven parts of the surface.

Use the same product to fill and round the corners in order to create a profile with a bending radius not less than 2 cm. MapeWrap 11 or MapeWrap 12 must be applied within their pot-life, therefore timing is vital in order to use the whole pack within the given time.

The MapeWrap fabrics must be applied over the still fresh MapeWrap 11 or MapeWrap 12.

Precautions To Be Taken During And After Application

No special precautions need to be taken at temperatures between 5°C and 30°C. In hot weather do not expose the material to direct sunlight. Levelling should be carried out during the cooler hours.

Cleaning

Due to the strong adhesion of MapeWrap 11 and MapeWrap 12 also on metal, it is recommended to wash the working tools with solvents (ethyl alcohol, toluol, etc.) before the product dries.

Consumption

1.55 kg/m² per mm of thickness.
