Cementitious Waterproofing Fosroc Nitoproof 600 Pf, Packaging Size: 25 kg

Product Details

Nitoproof 600PF is used to provide continuous, seamless, water and vapour proof membrane for concrete. Typical applications will include roofs, podiums, balconies, planters, floor slabs, suspended floors, patios, bathrooms, inspection pits, swimming pools, bridge decks, foundations, basements and tunnels. Advantages   Non-toxic formulation   One coat application for horizontal and inclined surfaces   Cures to form a permanently flexible, resilient barrier over a wide range of temperatures   Forms an impervious barrier which resists aggressive soil conditions   Excellent continuous adhesion to concrete prevents lateral water migration   Irreversible chemical cure does not permit melting or flow of film at elevated ambient temperatures   Capable of bridging substrate cracks up to 2mm   Easy to apply, requires no special equipment Description Nitoproof 600PF is single component liquid polyurethane. It cures by reaction with atmospheric moisture to form a tough, elastomeric, waterproof membrane. Nitoproof 600PF is designed for use on horizontal and vertical surfaces, covered by a protective screed or render. Typical results from membrane cured for 28 days: Typical properties Technical support Fosroc offers comprehensive technical support, including help at the design stage, application advice and on site problem solving.

Specification clauses Supplier specification Where shown on the drawings, the liquid applied, elastomeric polyurethane waterproof membrane shall be Nitoproof 600PF obtained from Fosroc. It shall be used in accordance with the manufacturer's current application instructions. Performance Specification The liquid applied, elastomeric waterproofing membrane, where shown on the drawings, shall be made of hydrocarbon free polyurethane. The membrane when cured shall be capable of an extension of not less than 600%. Its tensile strength shall exceed 1.9 N/mm² and the water vapour transmissions shall be less than 1g/m²/24 hour. It shall be used in accordance with the methods given in the manufacturer's data sheet. Application instructions Preparation All surfaces to be waterproofed should be clean, sound and dry. Priming of good quality, dense concrete is not necessary. For absorbent surfaces such as porous concrete a mixture of 1 part Nitoproof 600PF and 2-4 parts xylene, dependent on porosity of substrate, is used to seal the surface. Cracks Shrinkage and non-moving cracks should be pre-retreated with not less than 1.5 mm coating of Nitoproof 600PF extending 75mm either side of the crack. Allow to cure before general application. Right Angle Bends All critical right angle bends must have a minimum 25 x 25mm angle fillet installed prior to application of Nitoproof 600PF. All angle joints, protrusions and stress points should be pre-treated with heavy application of Nitoproof 600PF extending 50-100mm either side of the detail. Any pretreated areas must be cured overnight before general application of the membrane.
