Anti moss and stain protection for stone and paving

Signo Flexiguard is a stain-resistant formula specifically designed to coat porous silicate substrates, such as stone, concrete, terracotta and clay. Once applied, a protective layer less than 1-nm thick (80,000 times thinner than a human hair) bonds with inner pores of the substrate to leave a smooth, anti-stain, non-discolouring surface layer.

The coating is optically clear, UV stable, chemically inert and extremely durable, having both hydrophobic and oleophobic capabilities. It will not peel or flake and is unaffected by extremes of temperatures from minus 350 up to 45°C.

Signo Flexiguard offers protection against:

• Embedded and ingrained soiling, mould or fungal growth
• Abrasion and frost damage
• Chemical attack including, oxide corrosion by acid rainwater, damage by alkaline runoff from construction materials such as cement, concrete and plaster, and from fat, grease and oil products
• Corrosion by salt and other climatic coastal and marine conditions

Structure

Solvent-free Signo Flexiguard is made up of silicon dioxide molecules whose surface energy is modified by anti-bonding molecules. On application to the porous substrate, silicon dioxide molecules from the coating and the substrate start to bond together releasing the anti-bonding molecules. These molecules migrate to the surface creating an ultra-smooth, protective outer layer, and changing the status of the porous substrate from high to low energy. This low energy status is fundamental to the repellent qualities offered by treated surfaces.

As the silicon molecules in Signo Flexiguard bond seamlessly with those lining the inner pores of the substrate, the anti-bonding molecules form a highly protective surface breathable layer. By preventing a build-up of water, dirt or oil, the growth of mould, fungi, moss and bacteria is inhibited.

Benefits

• The surface quality is restored to its original state, becoming highly water and grease repellent, and resistant to abrasion
• Contaminates are unable to adhere to the surface
• Cleaning becomes much easier and less frequent – required 50–70% less often and withstands high-pressure cleaning (up to 50–60 Bar)
• The lifespan of the substrate is extended because of reduced cleaning cycles
• The surface remains clean and will not discolourTreatment methods
  Applied by surface spraying onto deep-cleaned surfaces, Signo Flexiguard can be applied almost anywhere: on site, at manufacturing premises or in a dedicated application centre.

Treatment methods

Signo Flexiguard can be applied on new surfaces during manufacture or installation, or to restore existing surfaces to their original quality [true?]. Hardening at 20°C, the treatment requires no additional energy or UV-light during application.

Applications

• Sandstone
• Precast concrete blocks
• Terracotta
• Brick or clay
• Stone panel floor and wall coverings
