Instructions for use

Product preparation


Prepare a plastic consistency mortar by mixing a 25 kg bag of weber.rep 314 RD with 2.75 to 3.5 liters (2,5 to 3 liters for Lebanon) of clean water. Mixing must be done for at least 3 minutes until a homogeneous paste is obtained. Do not mix it with an other hydraulic binder (cement, lime or gypsum) or an admixture.


For a thickness of more than 30 mm, weber.rep 314 RD may be used as a micro-concrete. In this case, mix a 25 kg bag of weber.rep 314 RD with 3.5 liters (2,5 to 3,5 liters for Lebanon) of water and 15 kg of 3/8 aggregates.

Product application

Surface preparation

weber.rep 314 RD may be applied on sound concrete, masonry, rock or similar materials.Remove damaged concrete and laitance by chipping with a pick or cold-chiselling to get a rough surface. The surface must also be free from any trace of grease or oil. Saturate the surface with water by copiously spraying just before application, and if possible, 6 hours before application as well.

Product application

For a thickness of more than 30 mm, weber.rep 314 RD may be used as a micro-concrete. In this case, mix a 25 kg bag of weber.rep 314 RD with 5 liters of water and 15 kg of 3/8 aggregates. weber.rep 314 RD must be used within 10 minutes (at 30ºC) from mixing. Re-mixing with an extra amount of water is not recomended. After application, protect the surface by using a curing compound like cure WH or cure Y 40 or by covering with properly secured plastic sheeting. Ideal application temperature is between + 5ºC and + 35ºC. If the application temperature is higher than 35 ºC, make sure to use cool water to keep the mixed mortar temperature below 30 ºC.


Mortar: 13 liters per 25 kg bag.
Micro-concrete: 20 liters per 25 kg bag.
