Preparation of substrates

Old water-dissolvable paint, glue or limestone remnants have to be removed thoroughly. Non-solid paint-leftovers can be brushed off first. Strong absorbing, porous substrates must be prepared with Tierrafino contact fine. Smooth and non-absorbing surfaces, like a coat of varnish or a layer of oil, should be roughened up with sandpaper and/or treated with Tierrafino contact fine. Please also see the measurement of quantity chapter at the bottom of this page.


On a light, equal surface one layer can be sufficient. On strong absorbing surfaces (new stucco, lime-sandstone, etc.), it is advisable to first apply one layer of clay colors Tierrafino i-paint thinned with water. When this layer has completely dried up, the final layer can be applied, without thinning. Every layer of i-paint must be completely dry, before another layer is applied!

Finishing technique 1

Clay colors paints Tierrafino i-paint can be applied using a roller or a brush. When ipaint has somewhat dried up after a few minutes, it is possible to leave a very fine streak by again brushing the surface gently with your paint brush. Vertical or diagonal streaks will show "movements" on the wall, due to varying structures in the surface of clay colors Tierrafino i-paint.

Finishing technique 2

To simulate a coarse structure ipaint, it is possible to use Tierrafino Contact, a quartz sand primer which does not only leave a coarse clay finish, but it also fixes any loose remnants on the wall. Once Tierrafino Contact has fully dried out, paint the surface with clay colors Tierrafino i-paint.

Finishing technique 3

To create another coarse, textured ipaint it is possible to add Tierrafino clay plaster. This can be done by mixing a maximum of 5% clay plaster to a bucket of i-paint. The Tierrafino clayfinish plaster must be mixed in well.

If more than 8% clay plaster is mixed in with clay colors Tierrafino -ipaint, the surface should be treated with Tierrafino Fix. Note: Tierrafino Fix should be applied, after the last layer has completely dried up.

Finishing technique 4

When clay colors Tierrafino i-paint is applied onto an existing 4 mm layer of Tierrafino clay plaster, it is possible to polish a shiny finish by using a plastic trowel and a polishing stone (for information on polishing stones please read Tierrafino Stone page on this website).

To create a shiny finish on other substrates than clay plaster, much more i-paint should be applied to achieve a thick layer of paint onto which a shine can be polished.

Please note: this finish is not a waterproof finish like Tierrafino Stone.

Finishing technique 5

To Tierrafino i-paint pigments can be added. This gives the possibilty to create a semi- transparent veiled layer onto existing clay colors paints or clay plaster.

Leave the pigments to soak in enough water to make a paste, and leave to soak for at least a few hours. The mix should be stirred into Tierrafino i-paint in one go. For very color intensive pigments (ultra navy blue / purple, mahogany or Pompeî-red) it is very important to mix well. Note: For a durable and equal surface of Tierrafino i-paint, it is best to apply 5-8% pigment or Tierrafino Clay plaster. If more than 8% is mixed in with Tierrafino i-paint, the surface should be treated with Tierrafino Fix. Notice: Tierrafino Fix should be applied after the last layer has completely dried up.

Measurement of quantity

0.125 litres Tierrafino i-paint per square meter, about 8 square meters per litre per one layer applied.

On most substrates two coats of i-paint will cover well.

Substrates that have not been prepared, or have very contrasting colors with the color of the i-paint, may need to be painted for a third or fourth time, that is why we suggest to use Tierrafino Fix before application of Tierrafino i-paint. This will reduce the shining through of the substrate. However we also advise to prepare the substrate in such a way that it is uniform of colour.
