< 340 g/L

4.5 - 6.5 mils (refer to Yield section for consumption)

+8 °C min. / +35 °C max.

≤ 80 %

Substrate and ambient temperature must be at least +3 °C above dew point.

No special curing requirements, but must be protected immediately from rain for at least 4 to 5 hours at +20 °C (+ 68 °F).

4 - 6h when cured at +23° C and 50% H.R.

~3.94 to 5.62 m²/L to achieve a 7 - 10 mils w.f.t (4.5 - 6.5 mils d.f.t) per coat.

Note: Generally, 1 coat is sufficient on a suitably prepared, uniform substrate.

This consumption is theoretical and do not allow for any additional material due to surface porosity, surface profile, variations in level, wastage or any other variations. Apply product to a test area to calculate the exact consumption for the specific substrate conditions and proposed application equipment.

• For concrete surface preparation, refer to the ICRI No. 310.2R guideline and provide a CSP 1-2.
• Substrate must be clean, dry, sound and free of all contaminants such as dirt, oil, grease and loose friable material which can reduce the adhesion of the coating.
• On substrates with a rough surface profile, it will be difficult to produce an even coating thickness. This may result in reduced protection and cleanability. Prelevelling or smoothing the surface is recommended before coating application.

Always perform an application test in an inconspicuous area to confirm appearance before applying to the designated area where the application will take place.

Application by brush or fleece roller:

• Apply the Sikagard®-5850 evenly over the surface.
• The coating must be continuous, pore free and to the required surface finish.
• Protect Sikagard®-5850t from heavy rain or rain showers until dry to prevent surface damage.

Application by airless spray:

IMPORTANT: Do not use aerosol car body type spraying equipment.
Note: The airless spray may not give a smooth or acceptable finish. It may be necessary to back-roll the coating with a roller to ensure a suitable finish and film build-up.

• Spray apply the Sikagard®-5850 in a continuous operation and at a speed to achieve a consistent thickness.
• The coating must be continuous, pore free and to the required surface finish.
• Protect Sikagard®-5850 from heavy rain or rain showers until dry to prevent surface damage.

• Clean all tools and application equipment with white spirit immediately after use. Hardened material can only be mechanically removed.
• Clean airless spray equipment at regular intervals to prevent harden silicon particles blocking the spraying tip.

Graffiti removal
IMPORTANT: Do not use rotating nozzle on high-pressure cleaning equipment.
As a general rule, always remove graffiti as soon as possible using either of the 2 options:

• Cold-water high-pressure jetting / cleaning equipment from 1200 to 1500 psi (80 to 100 bar) from a distance of approx. 4" (100 mm) from the substrate.
• Cold-water low pressure washing and rubbing down with a suitable absorbent clean cloth or a soft scrubbing brush.

Poster removal
Posters applied with water-based paste glues do not bond on substrates treated with Sikagard®-5850.

They will either fall off under their own weight or can easily be removed with minimal effort.
