Application thickness will vary with profile and alignment of substrate. When fairing a blow holed surface that is exposed to direct sun, it is important to use the full filler loading (2 parts base, 1 part hardener, 6 parts filler by volume). Using a lower filler loading may lead to the Nitomortar BH bubbling. If sagging occurs during application, the Nitomortar BH should be completely removed and re-applied at a reduced thickness on to the substrate. Finishing Any ridges left by the trowel can be brushed out while the material is still wet or ground down with a carborundum stone before overcoating. Important note: do not use solvent to thin component as this will prevent proper cure. High temperature working At ambient temperatures above 35°C, Nitomortar BH will have shorter pot life and working life. The materials should be stored in the shade or in air conditioned environments and should not be applied in direct sunlight. Curing Curing protection is not necessary for Nitomortar BH. Overcoating Nitomortar BH will generally be overcoated. As such overcoating operations can take place as soon as the Nitomortar BH has hardened. If the Nitomortar BH is not exposed to moisture (water, flow, condensation etc), the overcoating window at 23°C will be 48 hours. Otherwise the Nitomortar BH should be lightly abraded, followed by dust removal, in order to provide a suitable surface for subsequent layers. For further advice, consult your local Parchem sales office. Estimating Supply Nitomortar BH: 8 litre pack (base, hardener, fillers) Solvent 10: 4 and 20 litre pails Coverage Nitomortar BH: 4 m² @ 2 mm thickness 8 m² @ 1 mm thickness Storage Shelf life Nitomortar BH and Solvent 10 have a shelf life of 12 months at 20°C if kept in a dry store in the original, unopened containers. Storage conditions Store in dry conditions in the original, unopened containers. If stored at high temperatures the shelf life may be reduced to 4 to 6 months. Fosroc® Nitomortar BH
