Product Description 

Our smoothing boards are handmade and made of wood. They come with a natural sponge (viscose sponge) attached, which has a great absorbency and a coarse structure.

Field of Application 

Our smoothing boards are, among other things, suitable for applying sand lime and finishing coat.

Usually, smoothing is carried out using one of the following methods:

Method 1

Is typically chosen as a foundation for a subsequent whitewashing or coating with silicate paint (silicone free). The mortar is applied in the thinnest layer possible. Excess material is removed with the edge of a steel board or a trowel. Then the mortar is smoothed 32 with a smoothing board that is moistened with water. Smooth all the way to the base to achieve a thin layer and expose protruding bricks. If you choose to smooth with coloured mortar or glazers with coloured lime water, you should count on any repairs or uneven base to show.

Method 2

Is used if you want a completely covering surface treatment with coloured mortar or glazing with coloured lime water. To make the absorbency of the foundation even and to ensure a good adhesion and an even thickness of the layer, a two layer technique is used: The first layer is rough-casted or grounded with a mortar that is no stronger than the foundation but should be stronger than the finishing layer. When choosing the mortar type, you should consider the condition of the foundation. The finishing layer is applied with a steel board in an even, thin layer and smoothened after the foundation has hardened.

Method 3 

Is used if you want a completely covering surface treatment with coloured mortar as finishing plaster on a newly plastered base. The mortar is applied with a steel board in an even, thin base and smoothened. Coarse plastering can also be carried out with coloured mortar that is smoothened and raked up nicely. Alternatively, you can give a finishing treatment as described earlier. Before the coarse plastering, the walls must be rough-casted at least one week before.

Storage

After use, the sponge is rinsed and washed thoroughly and stored in a tightly closed plastic bag. Used viscose sponges should only be re-used for the same colour type as it was previously used for.
