Why the need?

Natural Stone (limestone; sandstone; granite; slate; marble)

Concrete (cladding; cast structures; power floated floors)

Brick (walls & landscaping ground structures)

Clay & Terracotta (roof tile and floor structures)

  • Where a coating is not an option RapidGuard provides a solution.
  • There is no conflict of interest between coatings & RapidGuard just a synergy
  • Surfaces where a client does not require a change in colour or aesthetics, typically
  • The porosity of all these surfaces vary, but each one is vulnerable to water ingress, air pollutants, staining and the associated problems:
  • Duty of care requires these surfaces are given ‘a helping hand’ or else their life cycle is significantly reduced

How it works

How Rapid Guard works

  • Rapidguard modifies the surface energy of a substrate.
  • Liquids penetrate a substrate when:
  • The solution is to modify the superficial tension of a substrate, taking it below that of liquids.
  • Surface tension – mN/square metre

Material                                             Superficial Tension         

Limestone                                         -95

Concrete                                           -80

Brick                                                   -75

Granite                                               -60

Water                                                -72

Oil                                                       -30

Solvent                                               -20

RapidGuard treated surface         - 5 to 10





  • RapidGuard is a suitable surface treatment for protecting porous building surfaces
  • 100% invisible when dry – not a coating
  • Surface impregnation product
  • Even works when micro cracks are present in a surface
  • Long lasting (>10 years)
  • Prevents ingress of most types of surface contaminants, including water, oil dirt etc
  • Reduces chewing gu adhesion allowing easy removal
  • Limits moss and lichen growth by keeping a surface dry
  • Keeps extreme soiling (eg. Graffiti) at the surface enabling easy removal
  • Stops the ‘freeze-thaw’ cycle and a resulting deterioration of surface
  • Prevents re-appearance of efflorescence salts caused by the ‘wetting-drying’ cycle
  • Is non-film forming, thus allows a treated surface to remain breathable
  • Resists mild acids, alkalis and fuel
  • A surface treated with RapidGuard will benefit from an increased life-span and will be easier to maintain
