Clay Finishing

Description

Substrate

The substrate must be uniform, dry, absorbent and free of dust, paints and lubricants (oils, greases, etc.). Substrates must be moistened beforehand to improve adhesion and to protect the plaster from drying too quickly. Absorbent substrates must be wetted to saturation (water sprayed on the substrate will remain on the surface for at least 5 seconds before being absorbed). For smooth concrete, drywall and other smooth surfaces with poor adhesion, we recommend using a quartz adhesive primer beforehand to improve adhesion. When plastering wooden surfaces (logs, boards, chipboard with a smooth face, plywood, etc.), we recommend using a thin layer. Reed mat or reed board, wood fiber, cork board or other natural insulating material for insulation.

Conditions

The temperature of the substrate and the ambient air must be higher than 5 ° C. Clay plaster dries by evaporation of water. The room must be properly ventilated to dry plastered surfaces during hot weather. During plaster drying, it is recommended to use fans, blowers and dehumidifiers for ideal drying. Excessive extension and excessive humidity can lead to the formation of molds on the surface of the plaster, which is not dangerous to health. Once the surface is dry, the mold must be wiped off the surface. Finishing plaster with clay can be used as a base layer.

Preparation

Add 4-5 liters of clean water to a 25 kg bag and mix well for 5-10 minutes to make the mixture a porous and uniform mass. Preparing the mixture a day before plastering is best, at least 30 minutes before use. After it has sat, mix the plaster mix well again.

Installation l

(Final result – structural surface) Clean and wet the substrates. Apply a layer 4-6 mm thick. Level the surface with a long trowel or a long putty knife. Enable the plaster to harden and level the surface with a rubber float

Installation ll

(Final result – smooth surface) Clean and wet the substrates. Apply a layer 4-6 mm thick. Level the surface with a long trowel or a long putty knife. Allow the plaster to harden and level the surface with a damp sponge. Before it dries completely, gently smooth again with a damp sponge to remove the grain from the surface. Repeat the smoothing with a damp sponge when the surface is completely dry to remove any remaining sand grains.

Finishing

If the finishing plaster remains as the last layer, we recommend priming the surface with UKU primer. Before priming, wipe loose sand with a brush or sponge. To achieve a smoother finish, with a finer grain or a smoother surface structure, we recommend the use of decorative UKU clay plasters with a wide range of shades, which can be enhanced with various natural decorative additives. Finishing clay plaster can be painted with UKU clay paint.

Maintenance

On-site repairs can be made for any surface damage. For this it is recommended to keep the same batch of storage powder. For a chip or blemish, dissolve a small amount of the mixture in a jar and dab the area with a fine brush. The plaster can be cleaned dry or re-coated with the same finishing material. Clay plaster is antistatic and does not collect dust. Oils and liquids are absorbed by the clay plaster.

Consumption

Depending on the uniformity of the substrate 7-10 kg/m² at a layer thickness of 4-6 mm.

Safety

Avoid inhalation of dust and contact with eyes. In case of contact with eyes, rinse immediately with saline solution.

Preservation

In dry conditions, clay plaster keeps forever. A bag that has moisture or water and has solidified can be reused by proper mixing. The date of manufacture for lot identification is on the packaging. There may be slight color differences between batches.

The application of the materials must be carried out according to the technical sheet and all drying times must be observed.
