Natural stones: Determination of sensitivity to accidental staining (NT BUILD 514)

NT BUILD 514

  • This Nordtest method describes a laboratory procedure for determining the sensitivity of natural stones when exposed to accidental staining. It contains a standardised procedure for the application of the stains, the cleaning and the assessment of the surface appearance after cleaning. It also covers the possibility to assess the efficiency of a surface treatment. Note that the method does not intend to present any de-staining technique!
