StoneFoam Stone Shield...
is a colourless and penetrating, high performance impregnator which protects honed and rough surfaces against oil, grease and water based pollution.

The product develops a strong oil and water protection and becomes fully effective approximately 24 hours after application (depending on temperature) without any visible change to surface colour or texture.

USES
Stone Shield has been specifically developed to protect mineral based outdoor walls and facades from water based pollution. Due to its outstanding 'steam diffusion' performance, this sealer is ideal for sandstone buildings (old and new) and any other type of stone/mineral based materials such as limestone and concrete.
The use of Stone Shield considerably reduces the amount of maintenance work required on stone buildings resulting in an unchanged look for many years. The shield reduces the amount of moisture on the surface & therefore the growth of mould & algae as well as discoloration due to air pollution.
It performs exceptionally well on honed to rough materials.
The effect on a polished surface is very limited and therefore not recommended.

PROPERTIES
Time saving one step application.
StoneFoam Stone Shield is based on the latest technology from Germany and consists of a mixture of organic and inorganic anti-adhesives in a water based solution.
This new 'smart' molecular technology reduces the 'specific surface' of the substrate which prevents water and oil based pollution from entering or attaching to the treated surface and allows easy removal and cleaning of such.
The surface treatment does not affect any steam diffusion of the treated materials and has the top rating in Europe for active moisture permeability ie being able to breathe so there is no build-up of subsurface moisture (EN ISO 7783-2, Classification I, Sp<0.14m).
The applied product is UV-resistant (California Test - 24,000 hours or 5 years of sunshine).
Stone Shield has perfect water repellence with no negative impact on the look or consistency of the stone.
The Stone Shield product is not affected by chlorine or salt water making it ideal for pool areas while ensuring that once treated, the surface remains unchanged.
Further test results (eg Salt Attack) are available at www.stonefoam.com.au

APPLICATION
Always test product on a small area first and wait 24 hours before treating a larger area.
Ensure surfaces to be treated are clean, dry and free of residues.
The product is to be applied undiluted and should be shaken or stirred before applying (depending on size of container).
To ensure maximum effect, generously saturate the surface with product using a clean brush or roller (depending on the size of the area to be covered). Saturation is reached when a thin wet film of sealer is visible on the surface.
If applying to vertical surfaces eg outdoor walls, ensure that product is applied from bottom to top in order to avoid 'pre-sealing' through spills.
The initial drying time of the product is 30 minutes - 4 hours. The full strength and protection is reached after 24 hours.
To maintain the treated surface, remove dirt & dust with water and neutral, non-aggressive cleaners. For large areas, a pressure washer or steam cleaner may be used.
For resealing, clean the surface well and re-apply a new coat.

PRECAUTIONS
Do not use cleaners containing solvents, methanol, Iso-propanol or those which are acid or alkaline based. Any abrasive cleaners or sponges will also damage the protection.
Only apply when the surface temperature is between 5º and 30ºC.
If applying by spray unit, ensure that appropriate protective gear is worn in order to avoid inhalation of spray or particles.
Resealing may be required after intensive cleaning or surface damage
