R159 Dirt Defence Optimum Surface Treatment

Dirt Defence Ultimate Surface Treatment has been developed using a short chain perfluorinated polymer technology and is a major step forward in stone and concrete sealers. Suitable for internal and external use.


Optimum Surface Treatment has been developed using short chain perfluorinated-polymer technology, a major step forward in stone and concrete sealers. This formulation is a technically advanced, dual hybrid perfluroinated impregnator, to provide excellent stain resistance with long lasting protection against weathering. Suitable for internal and external use. Provides a waterproof, breathable transparent, durable seal which can be used on natural stone (including honed and tumbled stone), concrete and block paving

How To Use

  • Ideal application temperature should be between 5ºc and 25ºc. Do not apply during rain, frost or when surface and air temperature is below 5ºc
  • Apply generous even coat with a brush, long pile roller or low pressure spray. (one generous coat is sufficient for surfaces with a low-medium porosity. For more porous surfaces apply a second coat whilst the surface remains damp from the first coat - must be wet on wet.)
  • Avoid pooling, by mopping up excess product.
  • Apply a further even, wet coat to the point of saturation, once the first coat has started to soak in. This method gives deeper penetration into the substrate. Allow the product to cure for 24 hours before subjecting to light use. For heavy use allow up to 7 days for the surface to reach optimum performance

Surface Preparation

Always test a small hidden portion of the substrate before use, to ensure the final result is satisfactory and to calculate consumption.

Surface should be clean, dry and free from dirt, soiling mould and algae before applying.



Keep in a dry place. Do not store below 5c. Keep out of direct sunlight and protect from frost.


The product is unable to work if applied over non-absorbent surfaces. Do not apply if rain is expected within 4 hours or before the surface is completely dry. Do not apply during rain or frost and when surface air temperature is <5c and > 30c


  • Penetrates and seals to give the highest levels of protection.
  • Allows stone to ‘breathe’.
  • Invisible when dry.
  • Excellent repellent of oil, grease and water.
  • Superb anti-stain properties with a strong resistance to dirt and grime.
  • Restricts moss growth, algae and other natural contaminates.
  • Water based - safer to use whilst being hard wearing and more durable
  • More environmentally friendly

Cleaning Of Equipment

Clean tools and equipment immediately after use with water.

Precautions For Use

For Health & Safety instructions, first aid measures, spillages and disposal instructions, see separate Health & Safety Data Sheet (MSDS).
