POLYMER REINFORCED NON SHRINKING MORTAR
FIXOCRETE CR46 is polymer modified cementitious thixotropic repair mortar for hand application to improve physical and installation properties and eliminate the possibility of shrinkage cracks. When mixed with recommended amount of clean water, it forms a grey trowel able mortar, which is suitable for interior or exterior applications on to vertical and overhead repairs. Application thickness 5-55mm. Concrete repair product is specially formulated to produce a shrinkage free mortar giving a smooth finish with excellent adhesion and good water resistant properties.

Application
1. Surface Preparation
The surface of the concrete to be repaired should be sound, clean and uncontaminated. The decayed or damaged area should be saw cut, keeping the sides of the area as square as possible. Loose materials must be removed carefully using suitable means such as sharp tools or chipping hammer. If the reinforcement is corroded make sure that the back of the steel is completely exposed. Then clean the steel to bright metal condition.
2. Priming
A. Reinforcement steel: on completion of the cleaning, prime the clean reinforcement steel using Zinc rich primer
B. Concrete: In the event of severe concrete damage due to chloride attack, it is recommended to use a bonding coat before applying. To achieve optimum bond between fresh and cured section, FIXOCRETE should be applied when the bonding agent is tacky.
3. Mixing
FIXOCRETE can be mixed by hand or mechanical means. Quantities not greater than 10 Kg may be mixed at a time. Slowly add the FIXOCRETE powder to clean and gauged water, working well to produce a smooth mortar. The consistency of the mix can be adjusted by the addition of more powder or water as necessary.
4. Placing & finishing
Whilst the primer is still tacky, apply the mortar mix and compact well. Application an be with trowel or a rubber hand glove to paste the material in place.
FIXOCRETE can be applied to desired thickness in layers on vertical and overhead surfaces. High build application can be achieved by using a formwork. While applying multiple layers, the previous layer should be cross hatched and allowed to set before applying the next coat.
FIXOCRETE should be cured in accordance with good concrete practice by
applying a suitable curing membrane or by covering the work with properly
secured plastic sheeting. Protection against rapid drying from wind, sun or
excessive heat is necessary.
