Description
Application instructions
Preparation
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%..
Note! Fresh concrete has to cure for at least 28 days before protection.
Exterior protection
Shake or stir product well prior to use. AGS 3500 can be applied with a low-pressure sprayer or airless spray gun. The protection is applied 2-3 times. Note! Allow some drying between applications. AGS 3500 can be applied to a damp, but not wet surface. Runs and/or excessive application can easily be washed off with water, following completion of work.
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 neutralised with water. Re-protect cleaned area.
Re-protection of cleaned surface
When removing graffiti, the protective coating is also normally removed. Re-protect 2-3 times with AGS 3500.
Dosage
Use in concentrated form.
Consumption
Varies depending upon type of surface material. Its porosity and capillary ability etc.
Guidelines
- Concrete, brick or similar, a total for 3 layers will be 0,25-0,3 ltr/m².
- Sandstone, plaster or other soft absorbent surfaces, a total for 3-4 layers will be 0,3-0,4 ltr/m².
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.
Storage
Store frost-free in closed original container.
Shelf life
Approximately 12 months in unopened container.
Precautions
