Roughen the surface and remove any laitance by light scabbling or grit-blasting. Saw cut or cut back the extremities of the repair locations to a depth of at least 5 mm to avoid feather-edging and to provide a square edge. Break out the complete repair area to a minimum depth of 5 mm up to the sawn edge. Prior to application of Nitomortar EL-HB all active hydrostatic leaks must be stopped by the use of Vandex Plug, a rapid setting mortar. Mixing Care should be taken to ensure that Nitobond EP primer is thoroughly mixed. The ‘hardener’ and ‘base’ components should be stirred separately before mixing to disperse any settlement. The entire contents of the ‘hardener’ tin should then be poured into the ‘base’ tin and the two materials thoroughly mixed using a suitable slow-speed drill and mixing paddle for 2 minutes until a fully uniform colour is obtained. The sides of the tin should then be scraped and mixing should continue for a further 2 minutes. Nitomortar EL-HB is supplied in the correct proportions to facilitate easy on site mixing. A slow speed electric drill with a suitable paddle can be used for efficient mixing. Satisfactory mixing can be achieved by removing the filler component bag and then thoroughly mixing all contents of the resin (part A) and hardener (part B) in the original container. Mix continuously for approximately 5 minutes until a uniform colour and gel-like consistency has been reached. The filler aggregate should then be added and mixing continued, ensuring that the aggregate is thoroughly wetted out with resin. Application Nitobond EP primer should be applied as soon as the mixing process has been completed. It should be brush or spray- applied to the prepared surfaces. Note: Primer can be applied on dry or damp substrates. The Nitomortar EL-HB should be applied to the primer coated substrate within 90 minutes at 20°C, ie. while the Nitobond EP is still tacky. If the Nitobond EP primer is allowed to dry, a second coat will be required. Apply the Nitomortar EL-HB with gloved hand and work the material firmly into the substrate surface. Build up to the desired substrate level and finish off with a steel trowel. To close the surface to a smooth finish lubricate the trowel with water. Note: DO NOT thin components as solvents will prevent proper cure. Nitomortar EL-HB should be applied only when the substrate temperature and the ambient temperature is above 5°C. Do not attempt to mix part packs as incorrect proportioning can severely affect the cured properties of the product. Cleaning Nitomortar EL-HB and Nitobond EP should be removed from tools, equipment and mixers with water or Solvent 10 immediately after use. Limitations Nitomortar EL-HB should not be used when the temperature is below 5°C and falling. Do not mix part packs under any circumstances. If any doubts arise concerning temperature or substrate conditions, consult your local Parchem sales office. Nitomortar EL-HB is designed for small pocket type repairs only. The total build and volume of material that can be applied in one application will depend on the size and geometry of the repair. Estimating Supply Nitomortar EL-HB: 9 litre pack Nitobond EP: 1.5 and 6.0 litre packs Solvent 10: 4 and 20 litre pails Product Code 342250 Nitomortar EL-HB Base 9L Pack 342255 Nitomortar EL-HB Hardener 9L Pack 342260 Nitomortar EL-HB Fillers 9L Pack Coverage Nitobond EP: 4 - 5 m²/litre Notes: the coverage figures for Nitomortar EL-HB and Nitobond EP 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 below 35°C in dry conditions in the original, unopened packs. Page 2 69
