Application:
Preparation:
It is essential that adequate preparation is carried out prior to the application of SpECbuild S10. This preparation should ensure the removal of all grease, oil, and loose material. The area to be reinstated using SpECbuild S10 should be cut back to a depth of at least 10mm. To avoid “feather edging,” it is advisable to neatly delineate the repair boundary by saw cutting to a depth of 10mm.
All corroded steel should be completely exposed, including the rear of the bar, to enable thorough cleaning. It is recommended that grit blasting be used to clean the reinforcing steel, and particular attention should be paid to the rear of the bar to ensure all corrosion products have been removed.
Substrate Priming:
Normally, it will only be necessary to pre-soak the substrate with clean water for a period of at least one hour prior to the application of the repair compound. Obviously, all water should be drained from the formwork prior to commencing with the application of the repair material.
Mixing:
The mixing water used must be in the range of 3.0 litres to 3.5 litres. The quantity used will depend on the type of application and the skill of the applicator.
Exposed steel reinforcing bars should be firmly secured to avoid movement during the application process, as this will affect mortar compaction, build, and bond.
Finishing:
SpECbuild S10 is finished by striking off with a straight edge and closing with a steel float. Wooden or plastic floats, or damp sponges, may be used to achieve the desired surface texture. The completed surface should not be overworked.
Curing:
SpECbuild S10 must be cured immediately after finishing in accordance with good concrete practices using wet hessian or polyethylene sheet.
Equipment Cleaning:
SpECbuild S10 should be cleaned from equipment using water immediately after application. Cured material can only be removed mechanically.

Packaging:
SpECbuild S10 is available in the following packaging:

SpECbuild S10: 25 kg bag
SpECcoat Zn25: 1 litre & 5 litre tins

The yield for SpECbuild S10 is approximately 12.5 litres (0.0125 m³) of mixed product, depending on added water at the nozzle, covering around 7-8 m² per litre.
