Fosroc Nitoproof 100, Packaging Size: 20 L

Product Details

Nitoproof 100 is designed to provide a continuous barrier to the passage of water and water vapour and can be used to produce vapour barriers, damp proof courses, linings to potable water tanks and pipes, below ground concrete protection, concrete curing by water retention, and corrosion protection to metal surfaces. Advantages ! Single component ! Easily and inexpensively applied; high coverage rate ! Tough and resistant to most naturally occurring chemicals ! Does not taint water ! Can be applied to damp concrete substrates ! Quick drying ! Excellent adhesion to most common building substrates ! Excellent water retention for use as a curing compound ! Successfully used for over 30 years in a wide range of environments Standards compliance Nitoproof 100 complies with BS3416:1975 Type 1A General purpose bituminous coating, BS3416:1975 Type II Bituminous coating for drinking water tanks and ASTM C309 water retention requirements for curing membranes. Description Nitoproof 100 low viscosity blend of selected bitumens in solvent dries to form a high quality tough bitumen film. Nitoproof 100 can be applied by brush, roller or spray equipment to prepared surfaces for a variety of purposes. Properties Test method Typical result Drying time : BS3900:C2:1972 21/2 hours Flexibility : BS3416:1975 Pass Chloride protection : BS3416:1975 Pass Effect on water : BS3416:1975 Pass Appendix B Overcoating time : 3 hours (min) Instructions for use Preparation Surfaces must be clean, dry, free from oil, grease and all loosely adhering particles such as rust, mill scale, mortar and cement laitence. These should be carefully removed by wire or stiff brushing and finally soft brushing or filtered compressed air to remove dust. Oil and grease should be removed by the use of a proprietary degreasing agent. For optimum adhesion to steel, grit blasting to SA21/2 is recommended. Nitoproof 100 can be applied to damp concrete, brick and plaster surfaces provided there is no free surface water or bleed. A test patch is recommend where there is doubt. Application Stir thoroughly prior to use. Damp-proof membranes, vertical vapour barriers Apply a full coat of Nitoproof 100 and allow to dry. Coverage rate should be approximately 3m2 per litre. Apply a second coat of Nitoproof 100 at right angles to the first coat. Water tank and pipe line protection Two coats of Nitoproof 100 should be applied as detailed above. Where necessary the coating can be thickened at floor/wall corners by forming a 20x20mm fillet onto the first coat of Nitoproof 100 and liberally coating with a second coat of Nitoproof 100. Concrete screeds or render Where it is necessary to cover the membrane with a screed or render, clean grit 2mm nominal size should be broadcast into the wet second coat to provide a mechanical key. All loose grit should be removed prior to placing the screed/ render. (Care should be taken to ensure that the membrane is not damaged during placing of the screed). Curing compound Apply two coats of Nitoproof 100 as for damp proof membranes. This will give a curing efficiency in excess of 80% and comply with ASTM C309. Nitoproof 100 can be applied to damp concrete.
