DIRECTIONS FOR USE
Surface preparation
Proper surface preparation is the key to any successful Epoxy application. The surface to be topped should be free of dust, laitance, oils or other 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 oicontamination, detergent washing with mechanical scrubbing should be followed by thorough water washing is recommended. 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 SL. 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. TecR Nova SL should be applied over the primer only after the primer coat has attained tack free dryness. This may take between 4 to 12 Hours depending on ambient temperatures and substrate porosity.
Mixing
TecR Nova SL is a three component system. For consistent results mix the entire contents of Part-B Hardener to Part-A Pigmented 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. To this homogenous mix slowly add Part-C aggregate while continuing to mix. The entire content of Part-C should be added to the mix and mixing should continue for another three minutes.
Application
Sufficient material required for the planned floor area to be covered should be made available at site. Mixing and application should proceed in a well coordinated manner.The homogenous mix should be applied over the tack free Primer coat quickly ensuring that the entire mix is used up well within the pot life. The poured Mix should be spread using a serrated trowel ensuring uniform thickness and simultaneously ensuring that the required thickness is achieved. The wet mix should then be spike rolled thoroughly before the material loses its workability. Trowel marks and overlaps should be neatly Spike rolled ensuring removal of entrapped air. Workability time will vary depending on ambient temperatures and on Relative Humidity. In any case it is recommended that sufficient trained manpower be made available at site to ensure that spike rolling is completed within ten minutes from pouring the mix. Avoid application at temperatures above 35°C or below 15°C.Floor Expansion joints should continue through the TecR Nova SLtopping.
Post Application
TecR Nova SLshould 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.
Storage and Shelf life
TecR Nova SL must be stored where temperatures do not drop below +8°C.Store in cool, dry location. Shelf life is maximum of 1 year from date of manufacture in unopened package. Failure to comply with there commended storage conditions may result in premature deterioration of the product or packaging.
CLEANING
