The fibres must be premixed simultaneously with sand + cement.

Mix dry for 1 to 2 minutes. Then add water and mix again for another minute, or 2.

To improve the processing and homogeneity of the mixture, we recommend to add our liquefying agent (1 dose per bag of cement).

If a professional concrete mixer is used at high speed, we recommend the following: Knead fibres, sand and cement for 5 minutes at high speed. Again, to improve the processing and homogeneity of the mixture, we recommend to add our liquefying agent (120/150 ml per 100 kg of cement).
