Heavy Duty Graffiti Remover

Sealer

•

BTech Graffiti Barrier was applied to one half of each of the materials one day prior to graffiti being applied (except the painted sample which was given two weeks to cure). Graffiti was then removed day after the graffiti application.

•

Graffiti materials consisted of automotive quick drying aerosol paints (red, yellow, black and silver), Texta inks (black and blue) and jumbo-sized permanent markers.

•

Removal was made using a hot water pressure system.

BTech Graffiti Barrier has been applied to the top right hand diagonal side. Bottom left hand diagonal side is untreated.

After cleaning with hot water (700C) delivered at 1000 psi, graffiti has disappeared from the area protected with BTech Graffiti Barrier. The remaining graffiti on the unprotected area was then treated with BTech Graffiti Heavy Duty Remover and washed away with high-pressure hot water (70¾C) at 1000 psi.

Right hand side is left untreated. BTech Graffiti Barrier has been applied to left hand side.

All graffiti disappears from treated side using high-pressure hot water (70¾C at 1000 psi). Even further pressure at 3000 psi (only advisable on very hard surfaces such as brick) applied to the untreated side does not remove Texta marks. Texta marks were easily removed after treatment with BTech Graffiti Remover.)

Top block is left untreated. The two blocks below are first sealed with BTech Graffiti Sealer (required treatment for any highly porous surface such as Besser block, sandstone, Heber brick, etc.) BTech Graffiti Barrier is then applied.

All graffiti disappears from the two treated bricks at the bottom, using high-pressure hot water (70¾C at 1000 psi). Remaining graffiti can only removed after applying BTech Graffiti Remover.

The three pickets on the right were left untreated. The five pickets on the left were treated with BTech Graffiti Barrier.

The treated pickets are restored to their original state with the use of high-pressure hot water (70¾C at 1000 psi). The untreated pickets on the right required treatment with BTech Graffiti Remover before graffiti would wash off.

The left hand side of this laminated timber was painted with satin gloss acrylic water-based paint. The right hand side was painted with exterior enamel. The panels were left to dry and cure outside, under cover for two weeks.

The treated panels were effectively cleaned with hot water at 70¾C at a pressure of 800 psi (lower than for other surfaces to avoid damage to paint surface).

The untreated panels required treatment with BTech Graffiti Remover before graffiti would wash off.

It was observed that the water based acrylic paint adsorbed more graffiti than the enamel and was therefore more resistant to removal.
