Clay finishing plaster

Description

Savivukumaja clay plasters are the only clay plasters manufactured in Estonia and the entire nearby region that have been tested on the basis of the German standard for clay plasters ( DIN 18947:2013 08 ). Based on the standard, the plasters belong to the higher strength class S II. Our fine finish clay plasters include clays of different colors and sands that have been carefully selected using a special gradation curve that gives them great workability and surface strength. Finishing clay plaster (granule size 0 2 mm, dry mix, tail fiber additive).

Colors

Dark red, red, brown, blue, gray.

Use

Suitable for plastering different surfaces in indoor conditions. Used to finish the base coat for clay cladding. Suitable for plastering various surfaces (wood, stone, bricks, clay, lime and other mineral plasters, reed board, straw walls,
concrete blocks, Aeroc, Fibo, etc.).

Property

Clay plaster regulates the humidity of the air in the rooms, accumulates heat, inhibits the formation of mold, neutralizes electromagnetic pollution, suppresses echoes and is suitable for people suffering from allergies. Savivukumaja clay plaster is 100% natural and reusable. It is possible to model round edges and different shapes.

Substrate

The base surface must be stable, weight-bearing, dry, absorbent, adhesive and certainly free of dust, paint and lubricants (oil, grease, etc.). We recommend using a thin reed mat when plastering wooden surfaces (panelling, chipboard and other wood-based boards with a smooth surface); use reed board, natural fiber board, cork board or other natural insulating material for insulation. We recommend using a full coverage jute fabric from the Savivukumaja selection for a harden the plaster in the second layer (with an overlap of 7 10 cm).

Conditions

The temperature of the base surface and the ambient air must be above 5°C. Tools Floats, trowels (rectangular modeling trowels, finishing trowels, Swiss trowels) and excitement. It is applied manually or with a plaster spray.

Mixing

Add 4-5 liters of clean water to a bag (25 kg) of dry mix and mix well. The best way is to prepare the mixture a day before plastering. The mixture should be left for at least half an hour. The plaster must be mixed after it has set.

Installation I

Structural finish

Clean and wet the base surfaces beforehand. Apply a layer of 4-6 mm. Smooth the surface with a long Swiss trowel or palette knife. Allow the plaster to solidify and level the surface with a rubber or plaster float using circular motions.

Installation II

Smooth finish

Clean and wet the base surfaces beforehand. Apply a layer of 4-6 mm. Smooth the surface with a long Swiss trowel or palette knife. Allow the plaster to solidify and level the surface with a sponge using circular motions. Before the surface is completely dry, smooth it again gently with a damp sponge to remove any loose grains from the surface. After the surface is completely dry, gently smooth it again with a damp sponge to remove any loose grains from the surface.

Drying

Clay plaster dries as the water inside it evaporates, so you need to properly ventilate the room during hot periods to dry the plastered surfaces. During the heating period, we recommend using fans, convectors and dehumidifiers for ideal drying. A prolonged drying period and excessive air humidity can lead to the formation of mold on the surface of the plaster, which does not harm your health. Once the surface is dry, you should wipe any mold off surface.

Finishing

If you use the Finish clay plaster as a final layer, we recommend that you apply the Savivukumaja finishing primer to the surface. Before applying the finishing primer, use a soft brush to remove any grit from the surface. To get textures of smoother surface or textures with a finer grain pattern, we recommend using Savivukumaja fine-finish clay plasters, which come in a range of different shades and can be enriched with different natural decorative additives.

Maintenance

Potential surface damage can be repaired. We recommend storing finishing materials from the same lot for this purpose. The plaster can be cleaned with a dry method (no water/chemicals/wet sponge) or covered again with the same finishing material. Clay plaster is antistatic and does not collect dust. Clay plaster absorbs oils and liquids.
