AGS 3502 – Graffiti Protection for Exterior and interior

Art. No: 3502

A water-carried all-weather long-term protection, formulated for most types of surfaces. Provides extra strong protection against spray paint, marker/felt-tip pens and mechanical damage. Also provides protection against airborne pollution and moisture. Correctly applied, life expectancy against graffiti is approximately 7 years and can be increased up to 10 years.
Permeable and allows protected surface to breath. Prevents graffiti from penetrating into substrate. A so called sacrificial protection, which means that surface must be re protected, following graffiti removal. AGS 3502 is readily biodegradable according to OECD test 302 B.


Clean off both graffiti and other contamination, such as traffic dirt, wax, oil and paint residue etc. from substrate. Mask and protect windows in a suitable manner. Ideal temperature for external application should be between 10-35°C. Minimum temperature is +5°C. Relative humidity must not exceed 95%.

NB! Fresh concrete has to cure for at least 28 days before protection.

Exterior protection

Shake or stir product well prior to use. AGS 3502 can be applied with a low-pressure sprayer or airless spray gun. The protection is applied 2-3 times.

Note! Allow some intermediate drying.

AGS 3502 can be applied to a damp, not wet surface.
Runs and/or excessive application can easily be washed off with water, following completion of work.
NB! Minimum 3 applications of AGS 3502 when a 10 year protection is specified.

Interior protection:

Painted substrate can be protected using a squeegee brush, roller or with low-pressure spray in combination with a squeegee. The protection is applied three times.

Exterior Graffiti removal

Method 1 – Normal substrate:

Remove graffiti with hot water and high-pressure (90°C & 90-150 bar / 1300-2175 PSI). In difficult cases, AGS graffiti removers are used in conventional manner. Re-protect cleaned area.

Method 2 – Sensitive substrate:
Apply AGS 3505 with a low-pressure sprayer. Allow a few minutes for the solvent remover to act and then rinse off with hot water (60-90°C & 60-80 bar/870-1160 PSI). The method is most suitable when substrate is brittle. Any graffiti left on the surface can be removed with AGS 3505 on a cloth. The cleaned area should be wiped with a cloth and water. Re-protect cleaned area.

Interior Graffiti removal:

Painted substrate: Dampen the area with AGS 3505 and wipe off graffiti with white nylon clothe or rag. If possible, use high-pressure hot water and wet-vac machines.

Porous substrate:
Rinse off with hot water and wet-vac.

Re-protection of cleaned surface:

When removing graffiti, the protective coating is also normally removed. Re-protect 2-3 times with AGS 3502.

Use in concentrated form.

Varies dependent upon type of surface material. It’s porosity and capillary etc.

•Concrete, brick or similar 0,10-0,15 ltr/m²/ coat.
•Sandstone, plaster or other soft absorbent surfaces 0,15-0,20 ltr/m²/ coat.

Drying- period:
The protected surface will be water- and graffiti-resistant after 2 hours and dry after 4 hours. Ultimate protective effect will be achieved after 72 hours.

Appearance on surface:

Transparent, mostly invisible dependent on type of surface. UV-resistant. Weather-, water-, and graffiti -resistant.

Note! Some building materials can darken or become shiny.
