Light grit blasting or acid etching should be carried out as for new concrete floors. Depending on the extent of the contamination, oil and grease penetration may be removed by hot compressed air treatment and primed with a primer coat of Nitoflor FC130. Adhesion tests must be carried out to confirm sufficient preparation. Asphalt surfaces Surfaces should not be coated if freshly laid since the asphalt will release volatile vapours which may blister the paint film. The asphalt should be 3 months old before coating and should be scrubbed with a detergent solution and allowed to dry before application. Note: Being a “flexible” material, asphalt may move more than can be accommodated by Nitoflor FC130 which could lead to cracks appearing in the coating. Mixing The individual components of Nitoflor FC130 should be thoroughly stirred before the two are mixed together. The entire contents of the base container should be poured into the hardener container and the two materials mixed thoroughly for at least 3 minutes. Using a heavy duty slow speed drill fitted with a suitable spiral mixing paddle. Coating The mixed Nitoflor FC130 should be applied to the prepared surface using a brush or lambswool roller. Ensure that the area is completely coated and that ‘ponding’ of the material does not occur since water may be trapped within the product, thus preventing complete cure. Airless spray application of Nitoflor FC130 is also acceptable however the first coat must be “back-rolled” with a roller immediately after application to assist the penetration of the coating into the concrete. The second coat may be applied as soon as the first coat has initially dried (typically 8 - 24 hours). The time will be dependent on the type of surface and the ambient conditions. Good drying conditions are required to allow complete evaporation of the water as the resin cures. Adequate ventilation and air movement is necessary. Cleaning Nitoflor FC130 should be removed from tools and equipment with clean water immediately after use. Hardened material can only be removed mechanically. Limitations Nitoflor FC130 should not be applied on to substrates known to suffer from rising damp or having a relative humidity reading greater than 80%. Refer to Parchem for further advice. Nitoflor FC130 should not be applied at temperatures below 10°C or where ambient relative humidity exceeds 85%. The life expectancy of Nitoflor FC130 will be reduced in areas of very heavy traffic such as around work benches, drinks machines etc. It is advisable to either:- a) specify additional coats in such areas or; b) specify a higher build system such as Durafloor HP or SL in such areas (see separate Technical Data Sheet). The low odour characteristics of Nitoflor FC130 is not necessarily an indication of non-tainting characteristics. Where tainting of food stuffs during application is possible we recommend separate tests are carried out in this instance. The Parchem range of flooring products includes specific grades for use in food processing areas. Being a semi-matt finish, Nitoflor FC130 may tend to scuff more than a gloss finish, however these marks can generally be removed with a detergent scrub.

Specification Clause Epoxy floor coating The floor coating shall be Nitoflor FC130, a two component water dispersed epoxy suitable for application by brush or lambswool roller. The coating shall be applied in two coats to achieve a total dry film thickness of approximately 100 microns.
