REPAIR MORTARS FIBROMIX 40 PRODUCT DESCRIPTION Fibre-reinforced thixotropic mortar with medium modulus of elasticity and controlled shrinkage, ideal for the structural repair of reinforced concrete. PRODUCT APPLICATION • To reinforce and repair reinforced concrete structures such as columns, beams and floors • To repair walls • To repair exposed and prefabricated concrete walls • To repair viaducts and dams • High impermeability • Good resistance against the aggression of atmospheric chemical agents • Excellent adhesion to concrete and reinforcement bars • Definitive intervention that guarantees long-lasting durability • Easy processing and quick spray application without formwork • Light colour Preparing the surfaces Perfect adhesion of the product to the surface, which is absolutely necessary to ensure repair resistance, depends on the quality of the surface preparation on which the mortar is to be applied. Therefore, the following steps must be carried out in advance: • Carefully remove all deteriorated parts by sand-blasting or bush-hammering • Roughen the surface, removing any film or cement latex • Clean each exposed reinforcement bar from rust and apply protective SANOFER on the cleaned bars • Thoroughly soak the surfaces with water, keeping them damp from when the application process begins Preparing the mixture FIBROMIX 40 is ready to use; mixing water must be added as follows: • Pour the mixing water into a mortar mixer (4÷4.5 l per bag equivalent to 17% in weight) • Slowly add the product while the mixer is on • Mix the mixture for approximately 3 minutes, then check its workability. If necessary, add a little water to adjust the workability (small variations in added water will not alter the characteristics of the product) • Continue mixing the mixture for another 3 minutes Application Apply FIBROMIX 40 with a trowel or a plastering machine in layers that do not exceed 3 cm.

REPAIR MORTARS FIBROMIX 40 Machine application is also possible using a continuous mixing plastering machine equipped with control flow meter. In this case cut the sacks along one side with a utility knife. Wait at least 60 minutes between one layer and another when thicker layers are applied and insert suitable reinforcement mesh on horizontal surfaces. Finishing A sponge float can be used for the FIBROMIX 40 finish, approx. 40-50 minutes (at +22°C) after product application. Following the float finish, and in any case not before a minimum of 24 hours after product application, FIBROMIX 40 can...
