USAGE
- Ideal choice for Heavy industrial production units, Automobile and auto- parts manufacturing units, Paper units, Storage areas, loading bays, etc.
- The topping when finished with TecR Nova FC range of floor coating systems is resistant to a wide range of chemicals making it a suitable flooring system for food processing zones and other chemical industries.
- The Screed mortar can also be used to repair spalled concrete columns, piers, bridge decks, etc.
DIRECTIONS FOR USE
Surface preparation
Proper surface preparation is the key to any successful Epoxy application. The surface to be coated should be free of dust, laitance, oils or other contaminants. Mechanical means like Grit Blasting or grinding should be adapted to remove surface contaminants. Mechanical means like Grit Blasting or grinding should be adapted to remove surface contaminants. The surface should be dry and should not suffer water ingress. Acid etching with diluted Hydrochloric acid followed by copious water washing will produce a surface similar in texture to fine/medium grit sand paper.
For old floors with heavy oil contamination, detergent washing with mechanical scrubbing should be followed by thorough water washing. For new concrete floors ample time should be allowed after completion of curing. The moisture content before application of the primer should not exceed 5%.
Apriming coat of TecR Nova Primer EP should be applied prior to application of TecR Nova SF. Mix the two primer components in one lot and apply immediately on to the surface. Work the Primer into the surface while ensuring that there are no puddles of excess material. A second coat should be applied if the first coat is fully absorbed into the substrate and the surface appears parched. Blow out any air bubbles in the primer coat. TecR Nova SF should be applied over the primer once the solvents in the primer have evaporated but while the coating is still in the tacky state. This may take between 1 to 3 Hours depending on ambient temperatures and substrate porosity.
Mixing
TecR Nova SF is a three component system. For consistent results mix the entire contents of Part-B Hardener to Part-A Base and mix gently for about 2 minutes preferably with a slow speed drill fitted with a stainless steel mixing paddle. The resulting homogenous mix must be of uniform shade. Care should be taken to maintain a clean environment in the mixing area to ensure that the mix is free of any contaminants. Part-C- Aggregates should be blended well before adding to the homogenous Resin-Hardener mix. Part-C- aggregates should be added to the Resin-Hardener mix slowly while continuing to mix. It is recommended that the blending of Parts-A, B&C be carried out in a forced action planetary type mixer. The entire content of Part-C should be added to the mix and mixing should continue for another three minutes. The blended mix should then be applied well within the pot life, after which the mix will not be workable.
Application
Sufficient material required for the planned floor area to be covered should be made available at site. Mixing and application should be proceed in a well coordinated manner. The homogenous mix should be applied over the tacky Primer coat quicky ensuring that the entire mix is used up well within the pot life. thickness and simultaneously ensuring that the required thickness is achieved. The spread screed should than be tamped with a box type stainless steel section to ensure uniform thickness. The leveled screed should than be finished with a stainless steel float to ensure maximum compaction and uniform surface finish. For further enhancing the finish the screed may finally be floated with a power trowel fitted with stainless steel blades. Workability time will depending on ambient temperatures and on Releative Humidity. In any case it is recommended that sufficent trained man power be made available at site to ensure that spreading and finising be complted within twenty minutes from mixing. Avoid application at temperaturs above 35°C or below 15°C.
Floor Expansion joints should continue through the TecR Nova SF topping R For areas with continuous wert operation and areas that require to clean top coats from the TecR Nova FC range may be applied.
Post Application
TecR Nova SF should be allowed to self cure at room temperature for a minimum period of 36 hours before being opened to pedestrian traffic. Vehicular traffic may be allowed after 7 days of curing at room temperature. Prior inspection by the applicator is advised before permitting traffic.

PRECAUTIONS
Prolonged inhalation of solvent vapors should be avoided. Direct contact with skin or eyes should be avoided. Use of gloves, goggles and other protective gear is mandatory. Enclosed spaces should have adequate ventilation. Where ventilation is inadequate use of suitable breathing apparatus is advised. In case of accidental eye contact thorough water washing is advised. This should be followed up with professional medical assistance. Neither the individual components nor the mix should be swallowed. The Primer and Tool cleaner are inflammable and should not be directly exposed to flame.
Storage and Shelf life
CLEANING
Tools and equipments should be cleaned with TecR Nova TC- Tool Cleaner when the mix is in uncured state. Cured mix can only be removed mechanically.
