Suitability depends on mineral surface chemistry and how the emulsion breaks and bonds. Some aggregates and soils carry surface characteristics that reduce adhesion with anionic droplets, leading to slow break, stripping, or weak bond under water. Fine clays and dusty soils can also destabilize the emulsion or prevent proper wetting, causing uneven coating and performance variability. The correct approach is to run coating and breaking compatibility tests with the actual local materials and to adjust grade selection, emulsifier chemistry, or additives accordingly rather than relying on generic assumptions.
