CONTENTS CONCRETE REPAIR CORROSION CONTROL GROUTS & ANCHORS PROTECTIVE COATINGS INDUSTRIAL FLOORING SURFACE TREATMENTS JOINT SEALANTS CONCRETE JOINTING JOINT FILLERS WATERPROOFING WATERSTOPS ROOFING TIMBER FLOORING ALPHABETICAL INDEX 63 Application Instructions Preparation All grease, oil, chemical contamination, dust, laitance and loose concrete must be removed by scabbling or light bush hammering to provide a sound substrate. Under normal circumstances an acid etch can be suitable. Steel surfaces should be grit blasted to white metal. Surfaces which show any traces of oil must be degreased with a chemical degreaser prior to grit blasting. Priming For maximum adhesion of heavily filled mortars, etc., the surfaces to be treated should be primed by applying a coat of unfilled Nitomortar 903 before placing the mortar. Mixing By volume – 2 volumes of resin to 1 volume of hardener By weight – 100 parts of resin to 45 parts of hardener Cleaning Nitomortar 903 should be removed from tools, equipment and mixers with Solvent 10 immediately after use. Estimating Supply Nitomortar 903: 1.5, 6 and 30 litre packs (200 litre drums of resin and hardener also available) Solvent 10: 4 and 20 litre can Coverage Nitomortar 903: 5 m²/litre (as primer) Litres of mixed 903 binder Litres of F4 fillers Kg of F4 fillers Yield Litres Consistency 7 day compressive strength 1 2 2.95 2.4 Fluid paste 76 MPa 1 3 4.42 3.2 Stiff paste 56 MPa 1 4 5.90 4.0 Trowellable 50 MPa 1 5 7.37 5.0 Dry mortar 45 MPa Note: the coverage figures for Nitomortar 903 are theoretical - due to wastage factors and the variety and nature of possible substrates, practical coverage figures will be reduced. Storage Shelf life All products have a shelf life of 12 months at 20°C if kept in a dry store in the original, unopened bags or packs. Storage conditions Store in dry conditions in the original, unopened packs. If stored at high temperatures, the shelf life may be reduced to 4 - 6 months. Fosroc® Nitomortar 903
