TEC MORTAR X
TEC MORTAR X
FIBRE RE-INFORCED REPAIR MORTAR
KEY BENEFITS AND FEATURES
- Anovel blend of select graded minerals, performance polymers and secondary reinforcement fibers resulting in a high performance ready-to-use repair mortar.
- Premixed, Single component- only requires addition of water to obtain free workable consistency.
- Excellent compatibility with concrete and masonry surfaces.
- Bonds extremely well to the substrate.
- Virtually no plastic shrinkage.
- Optimum moisture retention property requiring minimum curing.
- Good workability ensuring neat finish of repair jobs.
- Very thin set applications possible.
- Thick set applications should be done in multiple layers.
- Results in a dense, homogenous, low- porosity mortar.
- Ensures long term durability in repair jobs.
USAGE
- Ideal repair system for extensively damaged concrete.
- Highly recommended for spalling rectification in multi location repair jobs like in townships since it does require gathering individual components.
- Uniformity of mix can be maintained since clean water is the only outside component.
- Suited for external repair jobs in warm weather, since the presence of secondary reinforcement fibers will prevent shrinkage cracks.
- Ideal for repairing concrete damage resulting from corrosion of reinforcement.
DIRECTIONS FOR USE
Surface Preparation
All surfaces coming in contact with TecR Mortar X must be free of dust, loose particles and other contaminants. Corroded reinforcement should be exposed and all rust and scales removed. Steel should be cleaned to a bright color before application. Ideally Grit Blasting would be advised. In case corrosion has occurred due to the presence of chlorides high pressure water washing is recommended immediately after grit blasting. One break-free coat of TecR Beat ZR should be applied to the reinforcement and if needed a second coat. Concrete surface should be roughened to improve bond. Surface should be saturated with water for several hours prior to application of TecR Mortar X repair mortar
Mixing
Always use potable water. TecR Mortar X should be mixed in a paddle blade mortar mixer. The dosage of water shall be 4-4.5 litres per 25Kg bag of TecR Mortar X. Always place water into the mixer before adding TecR Mortar X to the mix. Continue mixing until a smooth, homogenous mix results. Do not re-temper the mix.
Application
Surface should be saturated surface dry prior to application of the mortar. Instead, the prepared concrete substrate may be provided with a bonding coat of TecR Bond SBR- Styrene Butadiene rubber based bonding Agent. TecR Bond SBR must be applied on a pre-wetted substrate. For repair sections exceeding 12mm the application of TecR Mortar X may be carried out in layers 10-12mm. Each of the secondary layers may be applied when the preceding layer is impression- free dry. Although application of the bond coat between each layer is not essential, use of repeat bond coats will improve durability of the repair. The entire mix should be applied within 30 minutes of mix preparation.
Curing
Although TecR Mortar X has excellent moisture retention properties, curing by mild dampening is advised for interior applications. Exterior applications must be water cured for a minimum of three days. Application of curing compound TecR Cure WB will enhance the durability of the repair job.
