The minimum temperature for applying Tierrafino Finish clay plaster is 5 degrees Celsius.
A bag of Tierrafino Finish clay plaster finishes (25 kg) should be mixed with 4-6 liters of water. Mix until a smooth paste is achieved. Tierrafino Finish can be applied straight after mixing, but after having left the clay wet in a bucket for a day, the plaster will be a little easier to apply. After having mixed clay finishes with straw and water, apply the mixture within a week.
Treat smooth substrates with Tierrafino Contact and highly absorbing substrates with Tierrafino Fix. Moisten absorbing substrates with water before applying clay plaster to give yourself enough time to finish Tierrafino Finish clay plaster in a good tempo. Only when the wall has been treated with Tierrrafino Contact should you not moisten the wall before applying clay plaster.
reinforce external corners jute or glass fibre mesh can be held onto
the corner onto which clay plaster is applied. Avoid plastering thick on
Tierrafino Finish should be applied with a laying on trowel or a machine-sprayer at a thickness of 2-4 mm.
After Tierrafino Finish clay plaster has set somewhat, when only the outer 1 mm is still workable, the wall should be shaped with a moist sponge. By rubbing the wall in circular motions material is taken away where there is too much and left behind where there is less than in direct surrounding areas. Rub along with the wall with not too much force, pushing too hard will create dents in the surface.
repeating rubbing with a sponge the wall will become finer in texture,
more and more small holes will be closed. However, because the wall is
not trowelled down anymore there will remain a more or less coarse
Now let the wall/object dry.
After Tierrafino Finish clay plaster has stiffened up a bit, when only the outer 1 mm is still workable, the wall should be shaped with a moist sponge. By rubbing the wall in circular motions material is taken away where there is too much and left behind where there is less than in direct surrounding areas. Rub along with the wall with not too much force, pushing too hard will create dents in the surface.
After the shine of water has dissappeared from the surface, Tierrrafino Finish clay finishes should be trowelled, polished with a plastic trowel. A metal trowel will leave stains from oxidation. When you press too hard with the plastic trowel onto a still too wet plaster, small or larger air bubbles will appear behind the plaster. Puncture this bubble with, preferably, a needle, and press the plaster back onto the substrate from all angles in the direction of the puncture. Now fill the puncture itself, if necessary.
Now let the wall/object dry.
the wall has dried but not fully, when it is still overall equally
moist, the wall must be gently wiped once more with a damp sponge and
then brushed with a horse hair- or coconut-brush. When brushing to soon,
stripe-marks will be left in the, still soft, Tierrafino Finish.
When brushing too late, the surface will be damaged by the brush, only
clay and sand will be rubbed from the wall. When you are too late, you
can solve the problem by wetting the wall with a plant spray prior to
brushing the wall.
Because of brushing the wall with a coconut-brush,
the real shine of Tierrafino Finish reveals itself. The
surface will be hard and wipe proof after brushing when it is done
intensively, by brushing too soft the wall will not be wipe proof.
Another way of finishing Tierrafino Finish is to rub the wall in circles with your handpalm, before Finish stiffened up. This doesn’t bring any harm to your handpalm.
Mix 1 liter Tierrafino Fix with 4 liters water, stir it well. Now add 25 kg Tierrafino Finish to the mixture and stir well until a spreadable paste is achieved. Apply this mixture to the wall or ceiling as described on the clay plaster application page of this web site.
After laying on
Mix 1 part Tierrafino Fix with 4 parts water, stir well into a bucket. Apply Tierrafino Finish as described, after stiffening of the plaster, sponge the clay plaster with the mixture of Fix and water. After this treatment, follow the Tierrafino Finish application as mentioned.
At a later stage
After Tierrafino Finish has been applied and succesfully finished, Tierrafino Fix may be applied in the following manner: Mix 1 part Tierrafino Fix with 4 parts warm water, spray regular water onto the finished clay plaster to make it overall equally moist, e.g. the colour of the clay plaster must be dark. Do not saturate the plaster, apply only just enough water to have the colour change. When the plaster is moist, apply the mixture of water and Fix with a sponge by way of very light circular movements onto Tierrafino clay finishes. Now brush Tierrafino Finish plaster as described on the Tierrafino clay plaster application page.
Note: the second way of applying Tierrafino Fix (after laying on) is regarded the most efficient and easy way of application.
Tierrafino Finish is suitable for veiled techniques. A veiled technique is a technique where more colours are used.
