Description

Flexiguard™ stone and paving sealant establishes a nanoscale breathable 3D coating on absorbent surfaces such as concrete, brick, stone and terracotta. Surfaces permanently repel water ingress, up to 95% of dirt and 98% of moss, lichen and fungus for a functional lifespan of over ten years. Once coated, the materials exhibit three-fold freeze and thaw resistance (EN 1338).


Flexiguard™ stone and paving sealant's adhesion to the OH surface guarantees permanence against weathering and mechanical and chemical abrasion, making it suitable for use on monuments, steps, war memorials and statues, as well as garden ornaments and fountains.


Flexiguard™ can be used as a secondary oil-repellent treatment in conjunction with TPM Concentrate impregnation on surfaces subjected to persistent wet weathering where appearance retention, as well as waterproofing, is required.


Features and benefits:

  • The existing surface quality is preserved, becoming highly water and grease repellent, and resistant to ingrained soiling, mould and fungal growth.
  • Contaminates are unable to adhere to the surface.
  • Cleaning becomes much easier and less frequent – typically required 50–70% less often – and the coating withstands high pressure (up to 50–60 bar).
  • The lifespan of the substrate is extended because of reduced cleaning cycles.
  • The surface remains clean and will not discolour.
