Product Options


- Preparation:

  • StoPrim Fungal: Fungicidal wash used where algae or fungus are present.
  • StoPrim Micro: Deeply penetrating, siloxane based primer supplied as a concentrate for dilution with clean water, which forms a water-repellent layer in the substrate and reduces the absorbency of porous surfaces and aids surface consolidation.
  • StoPlex W: Siloxane modified all-purpose primer on an acrylate base used to promote adhesion and regulate absorbency of porous surfaces.
  • StoPrep Contact: Acrylic based adhesion intermediary for siliconized bricks, ceramic tiles or other smooth or low absorbency backgrounds.

Levelling coat:

- Overall thickness:

Minimum thickness: 4 mm. Thicknesses greater than 12 mm to be a multi-coat application. Can be applied up to 20 mm for localized repairs.
