1 Nitoflor SL1000constructive solutionsNitoflor SL1000 UsesNitoflor SL1000 is designed for use in wide range of industrialenvironments where a lasting solution to floor maintenanceproblems is required. It provides a dense, impervious,coloured and chemically resistant floor surface which ishygienic and easy to clean. Typical applications include: Clean rooms Kitchens Plant rooms Light industrial plantsAdvantages Fast application - minimises downtime Chemically resistant - good resistance to a wide rangeof chemicals Durable - good abrasion resistance Hygienic - provides a dense, impervious, seamless floorsurface which is easily cleaned Attractive - available in a wide range of colours to enhancethe working SL1000 consists of graded aggregates bound in apigmented epoxy resin binder.

2 It is supplied as a four-component system, pre-weighed for on-site laid, it provides a smooth, light-reflective surface. It isavailable in a range of standard epoxy floor toppingThe designated floor areas shall be surfaced with NitoflorSL1000, a - mm thick floor-applied epoxy resinfloor topping. The topping shall achieve a compressivestrength of 85 N/mm2 and a flexural strength of 40 N/mm2 at 7days when tested to BS6319. At 35 C, it shall be capable ofaccepting foot traffic at 24 hours and vehicular traffic at values given below are average figures achieved inlaboratory tests.

If necessary, suitable damp-proofmembranes should be installed to prevent this.

6 Substratesshould not have a relative humidity greater than 75% at thetime of for useNitoflor SL1000 should be applied by specialist contractorswho must follow the procedures laid down in the ProductMethod Statement. Fosroc works with a network of suchapplicators who have been trained in the correct installationprocedures. The following steps are involved in the applicationwhich would normally take place over a 2 to 3 day PreparationIt is essential that Nitoflor SL1000 is applied to sound, cleanand dry surfaces in order that maximum bond strength isachieved between the substrate and the flooring system.

7 Alldust and debris should be removed prior to application of theproduct or its concrete floorsNew concrete, or cementitious substrates, should be at least28 days old and have a moisture content not exceeding 5%.Laitance deposits on new concrete are best removed by lightgrit blasting, mechanical scabbling or concrete floorsExisting concrete floors which require refurbishment must beprepared to ensure a strong adhesive bond between theflooring system and the existing floor. Mechanical cleaningmethods are strongly recommended particularly where heavycontamination by oil and grease has occurred or existingcoatings are present.

8 To ensure adhesion, all contaminationshould be removed. Proprietary chemical degreaser may beused on small areas of light contamination surfacesSteel surfaces should be degreased and grit blasted to SA2 immediately prior to application. The prepared surface shouldthan be treated with one coat of Nitoprime surfaces treated with Nitoflor SL1000 should be primedwith Nitoprime 25 designed for maximum absorption andadhesion to concrete the entire contents of the hardener tin to the base tinand mix the two primer components thoroughly for at least2 minutes - under no circumstances should part mixing mixed.

9 The primer should be applied immediately tothe prepared substrate using stiff brushes and/or primer should be well scrubbed into the substrate toensure full coverage, but care should be taken to avoid overapplication or ponding .Allow the primer to dry (see table below) before proceedingto the next stage, do not proceed whilst the primer is tacky as this will lead to unsightly marks in the finished substrates may require a second primer coat - whenthe first coat is directly absorbed into the substrate - butminimum overcoating times must still be observed (seetable below).

10 The overcoating times will vary slightly according to theporosity of the substrate. However, they should be inaccordance with the following ambient C:6-24 hours30 C:3-16 hours40 C:2-10 hoursMixingNitoflor SL 1000 flooring is supplied in four pre-weighedpacks (base, hardener, aggregate and colour pack) whichare ready for immediate on-site use. Part mixing of thesecomponents is not acceptable and will affect bothperformance and appearance of the finished should be carried out using either a forced actionmixer; or a heavy duty, slow-speed drill fitted withmixingpaddle.
