Graffiti Magic™ Anti Graffiti Paint - Surface Suitability Guide Download Guide as PDF document

Graffiti Magic is suitable for use on most common building substrates.
The table below is a general guide to suitability and surface preparation requirements.

 

Material

Suitability

Comments

Brickwork

OK

Suitable

 

Graffiti Magic plus Non Darkening Sealer

Ideally suited.

Depending on the porosity of the brick, substrate may darken on application of Graffiti Magic.

To prevent darkening and retain the original colour of the brick, seal with one coat of Non Darkening Sealer prior to application of Graffiti Magic.

 

Concrete / Render Fibro Cement

OK

Suitable

Graffiti Magic plus Non Darkening Sealer

Ideally suited.

Concrete, render, fibro-cement are porous substrates that will darken on application of Graffiti Magic.

To prevent darkening seal with one coat of Non Darkening Sealer prior to application of Graffiti Magic.

Treated Timber
(CCA treated)

OK

Suitable

Graffiti Magic

Suitable, i.e. sound attenuation barriers.

Timber will darken slightly on application of Graffiti Magic.

 

 

Sandstone

OK

Suitable over appropriate sealer

Graffiti Magic plus Non Darkening Sealer

Suitable, however it is recommended that surface is sealed with one coat of Non Darkening Sealer to retain the original natural features and to avoid darkening of the substrate.

 

Textured Finishes

OK

Suitable over appropriate basecoat/sealer

Graffiti Magic

Suitable for textured finishes when applied over the appropriate base coat or sealer.

 

 

 

 

Signage and Murals

Caution - get advice and/or test

Test for adhesion to assess for suitability

Graffiti Magic

Graffiti Magic does not adhere well to some plastics and painted surfaces.

Adhesion should be checked on all signage or mural surfaces.

Paint Adhesion TestRefer to Adhesion Test - Method Graffiti Magic to assess suitability before application.

 

Metals

Caution - get advice and/or test

Test for adhesion

Graffiti Magic

Generally recommended for most metals including Galvanised Steel, Aluminium, Bronze, etc.

However adhesion tests should always be carried out prior to application of Graffiti Magic to metal surfaces to determine suitability.

Paint Adhesion TestRefer to Adhesion Test Method - Graffiti Magic.

 

 

Painted Surfaces
(other than timber)

Caution - get advice and/or test

Always consult the paint manufacturer before application of Graffiti Magic to any painted surface.

Graffiti Magic should NOT be used over painted surfaces unless approved by the manufacturer.

Many decorative paints will soften and stain when aggressive cleaning agents are used to remove graffiti.

Graffiti Magic will NOT protect against staining and may lose adhesion if inappropriate graffiti cleaning agents have been used.

Untreated or Painted Timber

Not recommended

Not suitable

Not recommended on untreated or pre-painted timber surfaces.

Timber is an unstable substrate and generally requires repainting more frequently than stable substrates.

Graffiti Magic is a clear coating and does not protect untreated timber against the effects of ultra violet (UV) sunlight.

Adhesion Test Method

When Graffiti Magic is to be employed over existing paint work, signage or murals, etc. adhesion
should be checked over all surfaces as follows to ensure suitability:-

Finger dab Graffiti Magic to a small area of substrate (5-10 cm2 is sufficient) and allow to dry overnight.

For signage and murals, after sufficient dry time has elapsed, rub firmly across the test area with a finger to check for loss of adhesion.

For other painted surfaces, rub firmly with a rag soaked with White Spirit then finger rub across the test area as for signage and murals.

If there is no evidence of adhesion loss Graffiti Magic can be applied to a surface.
