| Anti
Graffiti Paint is suitable for use on most common building substrates.
However, there are some substrates where Anti Graffiti Paint is not
recommended: refer to the table below for suitability on a range of
common building substrates.
MATERIAL |
SUITABILITY |
COMMENTS |
|
Brickwork |
Suitable |
Ideally
suited. Depending on the porosity of the brick, substrate may
darken on application of Anti Graffiti Paint. To prevent darkening
and retain the original colour of the brick, seal with one coat
of Non Darkening Sealer prior to application of Anti Graffiti
Paint. |
|
Concrete
/ Render Fibro Cement |
Suitable |
Ideally
suited. Concrete, render, fibro-cement are porous substrates
that will darken on application of Anti Graffiti Paint. To prevent
darkening seal with one coat of Non Darkening Sealer prior to
application of Anti Graffiti Paint. |
|
Sandstone |
Suitable
over appropriate sealer |
Suitable,
however it is recommended that surface is sealed with one coat
of Anti Graffiti Paint to retain the original natural features
and to avoid darkening of the substrate. |
|
Textured
Finishes |
Suitable
over appropriate basecoat/sealer |
Suitable
for textured finishes when applied over the appropriate base coat
or sealer. Anti Graffiti Paint allows graffiti to be removed
using non-aggressive cleaning agents / methods that will not damage
the original textured surface. |
|
Painted
Surfaces
(other
than timber) |
Always
consult the manufacturer before application of Anti Graffiti Paint
to any painted surface |
Anti
Graffiti Paint should NOT be used on painted surfaces unless approved
by the manufacturer. Many decorative paints will soften and stain
when aggressive cleaning agents are used to remove graffiti.
Anti Graffiti Paint will NOT protect against staining and may
lose adhesion to some paints if inappropriate cleaning agents
are used. |
|
Signage
and Murals |
Test
for adhesion to assess for suitability |
Anti
Graffiti Paint does not adhere well to some plastics and painted
surfaces. Adhesion should be checked on all signage or mural
surfaces. Refer to Adhesion Test - Method Anti Graffiti Paint
to assess suitability before application. |
|
Metals |
Test
for adhesion |
Generally
recommended for most metals including Galvanised Steel, Aluminium,
Bronze, etc. However adhesion tests should always be carried
out prior to application of Anti Graffiti Paint to determine suitability.
Refer to Adhesion Test Method – Anti Graffiti Paint. |
|
Timber
(CCA treated) |
Suitable |
Suitable,
i.e. sound attenuation barriers. Timber will darken slightly
on application of Anti Graffiti Paint. |
|
Timber
(untreated or painted) |
Not
suitable |
Not
recommended on untreated or pre-painted timber surfaces as timber
is an unstable substrate and generally requires repainting more
frequently than stable substrates.
Anti
Graffiti Paint is a clear coating and does not protect untreated
timber against the effects of ultra violet (UV) sunlight. |
Application
Guide
Anti
Graffiti Paint is a unique protective coating system that must be applied
strictly in accordance with the manufacturer’s guidelines and directions.
Please
ensure that all directions are read and understood prior to application
of the product. Failure to observe these guidelines and directions
may downgrade performance and appearance of the substrate.
Suitable
Substrates & System Recommendations
Porous
surfaces such as concrete, render and textured finishes, etc.
Surfaces
should be sealed with Anti Graffiti Paint Non Darkening Sealer. Allow
24 hours for basecoat to dry thoroughly, then apply two coats of Anti
Graffiti Paint at 8-10mt 2
/ litre per coat allowing a minimum of four hours between coats.
Natural
Surfaces such as Sandstone, etc.
Surface
should be sealed with one coat of Anti Graffiti Paint Non Darkening
Sealer to retain original colour features and to avoid darkening of
the substrate. Allow 24 hours to dry thoroughly; then apply two coats
of Anti Graffiti Paint at 8-1010mt2
/
litre per coat allowing a minimum of four hours between coats.
Non-Porous
Surfaces such as Brickwork, etc.
Apply
two coats of Anti Graffiti Paint at 8-10mt 2
/ litre per coat allowing a minimum of four hours between coats. If
bricks are porous, apply one coat of Anti Graffiti Paint Non Darkening
Sealer prior to application of Anti Graffiti Paint to reduce darkening
and retain the original colour of the bricks.
Pre-painted
and Untreated Timber
Application
of Anti Graffiti Paint to pre-painted and untreated timber is NOT
recommended.
Most
untreated timber substrates are subject to grain cracking and generally
require repainting more frequently than stable substrates, such as concrete,
masonry, etc.
Anti
Graffiti Paint is a clear coating and therefore does not protect untreated
timber against grain cracking and the effects of ultra violet (UV) sunlight.
CCA
Treated Timber
For
smooth, non-porous surfaces, apply two coats of Anti Graffiti Paint
at 8-10mt 2
/ litre per coat allowing a minimum of four hours between coats. For
profiled or rough surfaces, refer to the manufacturer’s specification
for coverage rates.
Pre-painted
surfaces other than Timber
Not
generally recommended – see table above or refer to the manufacturer
for advice.
