Ideal for warehouses, car parks, light industrial buildings, etc. Advantages „ Simple brush, roller or spray application „ Efficient curing media for where compatibility is required between an efficient curing compound and a final seal coat „ Good resistance to abrasion „ Totally seals the concrete surface preventing dusting „ Available in clear, grey and special colours on approval „ Single component - no mixing „ Easily applied by maintenance personnel „ UV Resistant - non yellowing Description Nitoflor FC100 is a one component, penetrating, synthetic acrylic coating. It has excellent adhesion to cementitious surfaces and when cured forms a semi-gloss, flexible film. It penetrates the surface to bind together the particles to produce a harder wearing surface. When used as a floor coating, a minimum of two coats are recommended. One coat may be suitable when applied over approved and tested curing compound such as Concure CR. Technical Support Parchem offers a technical support package to specifiers, end-users and contractors, as well as on-site technical assistance Design Criteria Nitoflor FC100 is designed for application in two coats to achieve an approximate total dry film thickness of between 50 and 60 microns. Substrates must not suffer from rising damp. “Slab on ground” concrete floors should have a damp-proof membrane under the slab to prevent moisture transmission from the ground. Properties The values given below are average figures achieved in laboratory tests. Actual values obtained on-site may show minor variations from those quoted.

Good housekeeping is essential in areas where chemical spillage is likely to occur. It is especially important that such spillage should not be allowed to dry since much higher concentrations of chemicals will then result. Maintenance The service life of a floor can be considerably extended by good housekeeping practices. Regular cleaning of Nitoflor FC100 may be carried out using a rotary scrubbing machine with a water miscible cleaning agent or by hot water washing at temperatures up to 50°C. Refer to the Parchem “Floor Maintenance Guide”. Application Instructions Surface preparation It is essential that Nitoflor FC100, as a sealer, is applied to sound, clean, dry substrates in order to achieve maximum adhesion between the floor coating and substrate. Because Nitoflor FC100 is a relatively thin coating, the substrate must be fine textured. Any surface irregularities may show through causing excessive wear on high spots and changing the perceived colour of the coating. New concrete floors Dry removal of laitance by light grit-blasting or diamond grinding is preferable but, where this is not feasible, treat with an acid wash, followed by a neutralising solution then thorough rinsing with water and complete drying. Dust and other debris should then be removed by vacuum brush. Old concrete floors A sound, clean substrate is essential to achieve maximum adhesion when using Nitoflor FC100 as a sealer. Pressure washing should be carried out as for new concrete floors. Oil and grease penetration should be removed by hot compressed air treatment or with a chemical degreaser. A test area should be done to check sufficient preparation. January 2014
