Hydro-blasting, captive shot blasting or grit blasting equipment is necessary to ensure that adequate substrate preparation is achieved. Concrete substrates should be blasted with either high pressure water (<3000psi) or steel shot to remove the weak surface layer from the concrete and vacuum cleaned prior to the application of Durafloor N. In bund areas or where uneven substrates are being experienced, wet sand blasting and grinding followed by efficient vacuuming may be required. Steel surfaces Steel substrates to be blast cleaned (min Sa 21/2 standard of cleanliness). An angular profile amptitude of at least 75 microns is recommended for high-build applications (eg: Trowel or Self Smoothing applications over 2 mm). Application of Durafloor N should be applied as quickly as possible to prepared steel surface before corrosion occurs. Priming All substrates on completion of the preparation are to be primed with Durafloor N clear binder or Nitomortar 903 to provide a minimum wet film thickness of 150 microns. More than 1 coat may be required depending on the porosity of the substrate. When using the clear coating system, the first coat acts as a primer coat. When high build applications are required on vertical upturns or overhead, seeding the wet primer with a suitable clean grit will prevent the screed coat from sliding and provide an additional mechanical key.

Rc = Resistance to regular contact, but discolouration may occur. S = Resistance to short term immersion (24 hours). Sc = Resistance to short term immersion (24 hours), but discolouration may occur. Os = Resistance to occasional splashes. X = Not resistant. NB: The above resistance definitions are based on regular / sound housekeeping practices.
