PLASTER MIX
FOR CONSTRUCTION AND REPAIR WORK MULTIPURPOSE FINE-GRAIN

USAGE
For interior and exterior application in dry, humid and wet conditions.
To be applied manually or with a mortar gun.

SUBSTRATE
May be applied on concrete, light concrete, stone surfaces, plaster surfaces, moisture-resistant putty surfaces. Treated surfaces and other surfaces suitable for plastering.
The substrate shall be clean, hard and dust-free. Substances that can weaken bonding to the substrate such as loose paint, grease, dust and previously applied not moisture-resistant levelling substances shall be removed.

PREPARATIONS
Pour the required quantity of the dry mix in the mixing bowl.
Add water 15-17% (3.75-4.25 l per 25 kg bag or 1.1-1.3 l per 7.5 kg box).
Stir mechanically or manually until completely wet.
Let the mix stand for a while.
The ready mix is usable for 6 hours.

APPLYING
Very dry and porous surfaces should be previously moistened.
The mix is thrown on the wall with a trowel or pumped with a mortar gun.
Mixture applied on the wall has to be left to dry and thereafter smoothened with a float made of cork, wood or other material.
The layer thickness for covering larger areas is 4-12 mm.
For partial plastering the layer thickness may be up to 30 mm.

CURING
The curing time of a plaster layer depends on the thickness of the layer, humidity of the environment, temperature and ventilation conditions.
Before applying the next plaster layer it is recommended to let the first coat dry for
24 hours.
In case of very dry conditions it is recommended to moisten the plastered wall.
Cured surfaces are excellent to be treated with putty and painted.

LIMITATIONS
For plastering the temperature of the substrate, plaster and room must be over +5 0C.
This plaster is not suitable to be applied on greasy or oily surfaces and substrates that are not moisture-resistant.

STORAGE
Mix powder packed in bags shall be stored in a dry room.
Storage time of mix powder is 1 year.

CONSUMPTION
For covering 1 m2 with 5 mm plaster layer
6-7 kg of mix powder is needed.
