Product Description

Fixativ Easy 2K is a two-component, thixotropic mortar with very low emission of volatile organic compounds made from special hydraulic binders, fine selected aggregates, synthetic poly acrylonitrile fibers, synthetic polymers and special admixtures. After mixing with component B, the product forms a mortar with good workability. It is applied by trowel in a single layer from 3 to 30 mm thick to repair and smooth over concrete. Fixativ Easy 2K hardens without shrinking and is characterized by its excellent adhesion to concrete substrates. After hardening, Fixativ Easy 2K has the following characteristics:
• Low modulus of elasticity
• High ratio of flexural strength to compressive strength
• High adhesion to the concrete surface
• Little size variation with respect to hygrometric variation
• Excellent performance in adverse weather conditions;
• Resistance to aggressive chemicals.

Field of Application

• Repair of degraded concrete sections, corners of pillars and beams, balconies damaged by rusting of reinforcing bars.

• Filling of rigid joints.

• Repair of precast concrete sections.

• Canals and hydraulic projects where waterproof concrete is required.

• Repair of concrete subject to small deformations under loads.

Application Procedure

Preparation of the substrate

• Remove all deteriorated and loose concrete to form a solid, rough and strong substrate. Any areas previously repaired and which are not perfectly bonded must also be removed.
• Remove all dust, rust, cement laitance, grease, oil and paint from the concrete and reinforcement rods by sandblasting or hydro-sandblasting.
• Treat reinforcement rods with Ferroprimer 1K or 2K, according to the procedure given in the Technical Data Sheet of product.
• Saturate the substrate with water.
• Before carrying out repairs, wait until excess water has evaporated.

Preparing the product

Pour 6 liters of component B into a container and slowly add a 25 kg bag of Fixativ Easy 2K while mixing. Carefully mix the blend for several minutes then remove any powder which has stuck to the sides and bottom of the container. Mix again for several minutes to form a well-blended, plastic consistency, lump-free mixture. Fixativ Easy 2K remains workable for around 60 minutes at +10°C to +25°C.

Applying the product

Apply a layer of mortar from 3 to 30 m thick with a trowel or putty knife; no formwork is required. As soon as the mortar starts to set, tamp the surface with a sponge float. The waiting time required before carrying out this operation depends on surrounding weather conditions. To paint and protect the surface, apply a coat of an elastomeric product or an acrylic product.
