Application

• Partial depth rehabilitation of concrete beams, columns, and / or soffits in bridges, Parking garages, balconies or other concrete structures.
• Vertical and over head concrete and masonry repairs.
• Repairs in marine environments.
• Repairs reinforced concretes in industrial areas.
• Repairs precast concrete defects

Advantages

• One component, just add water, easy to apply
• Non- sag, can be applied in layers of 3 to 6 cm
• Shrinkage compensated, No cracks after hardening
• Superior bond to concrete and rebar surfaces
• Contains no added chlorides
• Water resistant
• Fiber modified mortar

Method of use Surface preparation

• Concrete surfaces: must be sound, free of loose or deteriorated concrete and free of dust, dirt, paint, efflorescence, oil and other contaminants.
• Mechanically abrade the surface substrate.
• Around of repair area should be saw-cut a minimum 10mm. leaving the concrete saturated but free of standing water (SSD).
• Remove the back of exposed and corroded rebar’s and clean the surface by wire brushing or abrasive blasting.

Priming

• Clean and prime exposed steel with: Cement (1): SA46 (1): water (1), Volumetric, one day prior to repair.
• Extra protection to the reinforcement in corrosive areas can be gained by use of FARCOTEK ZR.
• Concrete surface is primed with diluted SA46 with the ratio of SA46 (1): water (3). (Volumetric) the mortar should be applied while the primer is still tacky.

Mixing

In a clean container, add 2.5 to 2.8 kg water, using a slow speed drill and a jiffy mixer, gradually add the 20kg powder (bag) to produce a mortar with a smooth consistency and without lumps.

Placing

• While the primer is still tacky, apply the prepared mortar with either a gloved hand or trowel.
• Carefully compact the material tightly in to the substrate and at the back of the rebars to ensure optimum bonding.
• Maximum thickness per layer for vertical and horizontal substrates are 50mm and over head is 40mm and minimum 10mm.
• Apply the consequent layers when the previous achieved the initial setting. The setting depends on ambient and material temperatures usually 2 to 4 hours.

Protect the surface of newly applied material from direct sunlight and wind; cover the surface by wet burlap or plastic.

• Protect the newly applied mortar from freezing
• Apply FARTEX V554 at temperatures from 5 to 35°c

Consumption

20kg of V554 will cover 1 to 1.2m2 at 1 cm thickness.
