Betonfix FB

Betonfix FB is CE marked as structural mortar R4 according to the EN 1504-3 and it is compliant to the UNI 8147 standard.

The substrate must be perfectly clean, compact, free from dust, grease, paint, etc. Carefully remove the deteriorated and flaky concrete using a hammer until the substrate is compact. The superficial tensile strength of “pull off” concrete must not be lower than 1,5 Mpa, as per procedure of quality control of substrate, according to EN 1504-10. If substrate has lower mechanical properties please contact our Technical Department. Where metal reinforcements are visible, remove any adjoining concrete with a needle gun, hydrosand the entire surface and protect the metal reinforcements with Betonfix KIMIFER, applied by brush. Soak the area to be treated eliminating any pools of water when casting. Soak the area to be treated, taking care to remove, when casting, any pools of water. Mixing must be carried out in a cement mixer or in the mixer of the spraying machine for at least 5 minutes until you get a proper plastic, homogeneous, lump-free mixture. A mortar mixer or a drill equipped with an agitator can be used, it depends on the quantity to be prepared. Mixing must take place at low speed to avoid entrapping air. Introduce 3/4 of water required and continuously both product and remaining water until you get the consistency desired. Apply with a trowel or spray with suitable plastering. It is advisable to perform a bush-hammer based treatment on the whole area in order to achieve the correct roughness, then place, if needed, a suitable electro-welded galvanized metal mesh to ensure a higher stability of the intervention, and apply the mortar in order to create a coverage of the steel reinforcement bars with at least 2 cm thickness. When applied in several layers (higher than 3 cm), between a coat and the other run the levelling, improve the roughness with a notched trowel and wet the surface before applying the next layer. Wait at least 12 hours before laying the next coat.The maximum applicable thicknesses per coat vary for different types of applications, contact Technical Department. In the case of continuous restorations in thick layers, to optimize times and costs of intervention, think about the use of Betonfix CR (pourable) using suitable formworks. The setting values related to mechanized application are the following: • machine type model PFT G5, • with lung type D7, • pipe parameters: - diameter d=30mm, - length L=30m
