Suitable for interior and exterior plastering. Basic tones are grey and greyish white, in addition we have 11 coloured mixes.

Plastered surfaces are weatherproof and without microcracks. They can be washed with a high-pressure cleaner. Applied by hand or sprayed. Plastered surfaces accept façade paints and other paints suitable for plastered surfaces. For use on concrete, lightweight concrete, stone and plastered surfaces. When applying the second coat, the first coat has to set for at least 6-8 hours.  It is recommended to sprinkle the plastered surface with water when applying in dry conditions. After the final setting, the plaster is heat- and cold-resistant.

Product coverage: 6-7 kg/m2 at 5 mm thickness by hand, 3-5 kg by machine.

For internal and external plastering works. For dry, damp and wet conditions.

For substrates made of concrete, lightweight concrete, masonry, already plastered surfaces and other mineral surfaces suitable for plastering.
Siler-3 is a spray plaster ideal to be used as a finishing plaster in the UniTherm insulating system.
The substrate shall be clean, strong enough and dust-free. Substances, such as loose paint, grease, dust and non-moisture resistant levelling courses reducing bondage with the substrate shall be removed.

Add clean lukewarm water as approx. 17-22% of the weight of the mixture (4.25-5.5 l per 25 kg package).
Add the necessary quantity of dry mix.
Mix carefully with a mixer until the mixture is completely wet.
Wait for a couple of minutes and mix moderately once again.
Ready-made plaster should be used within 4 hours.

Very dry and porous surfaces should be previously moistened.
Treat weak substrates with Uninaks DEEP IMPREGNATING PLASTER.
When using a plastering machine cover all door and window openings and other surfaces that should not get plastered with a suitable material. Use a plastering machine with appropriate power and a suitable nozzle. Conduct test plastering before starting to cover public surfaces.
Best results are achieved when applying two layers on surfaces. Before applying the second layer, let the first layer dry for at least one day.
When manually applying use steel trowels.
The thickness of one plaster layer should normally be 4-8 mm, in case of partial plastering up to 1 cm.

The curing time of one plaster layer depends on the layer thickness, moisture content and temperature of the environment.
Before applying the next plaster layer let the previously applied layer dry for at least one day.
In extremely dry conditions we recommend moistening already plastered surfaces before new plastering and within 2-3 days after plastering. Cured surfaces are excellent for covering with paints suitable for mineral surfaces.

Substrate, plaster and ambient temperature during application process and a day after it shall exceed +5° C.
Freshly plastered surfaces shall be protected from direct sun and rain exposure.
The product contains cement. Contact with water causes an alkaline reaction. Can cause skin irritation. Upon contact with eyes rinse immediately with plenty of water.
