Sika Sikagard 850 Clear is ideal for use within the Sikagard Anti-Graffiti System as a permanent anti-graffiti and anti-fly poster coating. It is suitable for use on the following substrates:
Sikagard 850 Clear is sold ready to use with no dilution with solvent at job site. This anti-graffiti coating provides a permanent finish - graffiti can be typically removed more than 20 times without damaging the protection, or requiring a refresher coat, when using non-aggressive cleaning techniques.
This clear topcoat also is ideal for protecting walls against fly posters. Posters will not bond onto the protected substrate or can be easily removed, even after many cleaning cycles.
To remove graffiti or fly posters, no chemical agents required for cleaning. Cleaning requires only cold-water pressure (80 to 100 bar) or cold-water low pressure washing and rubbing down with a clean cloth or scrubbing brush.
Strictly follow installation procedures as defined within the product and application data sheets. They must always be adjusted to the actual site conditions. Existing coatings must be tested to confirm their compatibility with Sika Sikagard 850 Activator and Sika Sikagard 850 Clear.
PRIMER
IMPORTANT - On rough substrates, use a brush to apply primer and make sure the primer covers all the surface, including voids. Allow the primer surface to dry and become tack-free before applying the top coat (~2–3 hours, depending on weather conditions). Allow Sika MonoTop mortars to cure for 3–5 days before applying primer.
Substrate (mineral) without existing coating or hydrophobic impregnation (including Sika MonoTop® products)
Apply Sika Sikagard 850 Primer evenly over the prepared substrate at the required consumption rate. Refer to Product Data Sheet. The primer must be continuous and pore free. Substrate (mineral or wood) with existing coating / lasure. Apply Sikagard 850 Activator evenly over the prepared substrate at the required consumption rate. Refer to Product Data Sheet.
The primer must be continuous and pore free. Substrate with hydrophobic impregnation. Prime with Sikagard 850 Primer evenly over the prepared substrate at the required consumption rate. Refer to Product Data Sheet. The primer must be continuous and pore free. For wood (uncoated) no priming is required.
TOP COAT
If applied over a primer or activator, refer to appropriate drying time / waiting time to overcoating. Application by brush or medium to long hair roller If required, mix the coloured pigment into the product until fully dispersed and a uniform colour is achieved.
Apply the Product evenly over the surface. The coating must be continuous, pore free to the required surface finish. Protect the freshly applied coating from heavy rain or rain showers until dry to prevent surface damage. Apply by airless spray. It may be necessary to back-roll the coating with a roller to ensure a suitable finish and film build-up.
