Betonfix TX

Betonfix TX è marcato CE come malta strutturale R3 sulla base della UNI EN 1504-3.

Carefully remove degraded and inconsistent concrete by hammering until you find a compact support. The "Pull off" concrete surface traction strength must not be less than 1.5 MPa, as indicated by the quality control procedures of the substrate according to EN 1504-10. If the substrate has lower mechanical characteristics, the designer will evaluate the measures to be taken (contact the Technical Department). If steel reinforcement rebars are exposed, remove the concrete in contact with them by using a needle gun; hydrosand the entire surface and protect steel reinforcement rebars with Betonfix KIMIFER applied to brush. The product is ready-to-use with just the addition of potable water per pack according to the amount indicated in the table above. Prepare the amount of Betonfix TX that you plan to use within next 15 minutes starting from mixing phase. 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. The substrate must be wet until SSD conditions are achieved, eliminating any exceeding water stagnation. Saturate the substrate with a Betonfix KIMIFER coat by brush and, on fresh, apply mortar with trowel. Once finished the work keep the surface with an adequate level of humidity. It is important not to mix the product once it has begun to set: it would lose all the chemical-physical properties. Do not use Betonfix TX to create continuous coatings such as plasters or skim coatings. In particular we suggest to use a plastering machine with the following characteristics: • Hose diameter: 30 mm • Hose length: 30 m • D7-pumps • All remaining characteristics corresponding to a plastering machine PFT G5
