The primer should be mixed in the proportions supplied, adding the entire contents of the ‘hardener’ tin to the ‘base’ tin. The two components should be thoroughly mixed together for 3 minutes. The mixed primer should be scrubbed well into the prepared substrate, taking care that all imperfections in the surface are properly coated and avoiding ‘puddling’ in depressions. If the primer is absorbed within 30 minutes, a second coat should be applied before continuing. Nitomortar 908 can be applied as soon as the primer has started to gel but still has surface ‘tack’. This is normally between 30 minutes and 4 hours dependent on the ambient and substrate temperatures. If primer cures hard, a second primer application must be made before application of Nitomortar 908. Mixing Thoroughly mix resin (white) and hardener (black) using a slow speed electric drill in a suitable container until an even grey colour is obtained. Do not attempt to mix part packs as incorrect proportioning can severely affect the cured properties of the product. Application Apply the mixed Nitomortar 908 to the prepared substrate by wood float, pressing firmly into place to ensure positive adhesion and full compaction, then finished with a steel trowel. Note: the minimum applied thickness of Nitomortar 908 is 5 mm. Cleaning Nitomortar 908 should be removed from tools, equipment and mixers with Solvent 10 immediately after use. Limitations Nitomortar 908 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. Estimating Supply Nitomortar 908: 10 litre pack Nitomortar 903: 1.5 and 6 litre packs Nitobond EP: 1.5 and 6 litre packs Solvent 10: 4 and 20 litre pails Coverage Nitomortar 908: 2 m2 at 5 mm thick Nitomortar 903: 5 m2 / litre (approx) Nitobond EP: 4 - 5 m2 / litre (approx) Note: The above coverage figures 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 908
