Tunto Stone

Genuine natural stone surface

Tunto Kivi (Stone) is a coating that contains natural Finnish stone, combining the inimitable beauty of nature and the value of a genuine material. It is suitable for coating interior walls and fireplaces, for instance.Tunto Stone can also be used to coat walls in humid spaces, but it is not suitable for direct contact with water.

Bring the Finnish bedrock into your home

Natural stone has the nature of rock, the firmness of mountains, and the warmth of the earth that can be felt up close. The delicate relationship between roughness and light form part of the natural vibrancy of Tunto Stone.

Spread stone with a steel trowel

Tunto Stone is a mass that is spread on the wall surface with a steel trowel. Although it is simple to apply, the result is stunning! Coat an entire wall or sections outlined with tape.

Standard colours directly from nature

Tunto Stone is manufactured from four different rock types: light-coloured limestone, gray and black granite, and black gabbro. Thanks to a patented tinting system, it is also available in 25 carefully formulated tintable colours that retain the feel of natural stone.

Mixing ratio
To be used unthinned
Application method
Application by steel trowel or spray. Rubbing  with a plastic  float, if necessary, in application of two coats.
CAUTION! Before spray application, remove the small metal piece which may have dropped into the paint can during tinting.
Drying time at 23°C and 50% relative air humidity
Recoatable after 24 hours in normal conditions.

Solids volume
approx. 1.5 - 1.7 kg/l, depending on stone, ISO 2811
Protect from frost.

Application conditions
The surface to be painted must be dry. The temperature of air, surface and coating must be at least +5°C and the relative humidity of air below 80 %.
Unpainted surfaces:
Clean the surfaces from dirt and dust. Level with a suitable Presto Light Filler. Prime all untreated surfaces with Varma Primer or Feelings Universal Primer. Paint the primed surface once with Harmony, Feelings Interior Paint or Joker. The paint should be tinted to the same color with the stone coating to be applied.

Previously painted surfaces:
Wash down previously painted surfaces with Maalipesu Cleaning Agent and rinse carefully with water. Fill possible holes with suitable Presto Filler. Paint once with Harmony, Feelings Interior Paint or Joker tinted to the same color with the stone coating, if the color difference between the substrate and the coating is significant.

Humid rooms:
Prime with Feelings Extra Durable tinted to the same color with the stone coating.

Application by steel trowel  (small areas)

Apply by steel trowel a smooth coat of approx. 2 mm at a time to an area of approx.1-2 m² . Smooth the coating by sloping the trowel lightly and gently over the surface. Check that the stones are spread abundantly and closely and  to the whole area. Adjust limits of pauses and borders of various cans to an unobtrusive spot.


Application by steel trowel and grinding (big areas)

On large uniform wall surfaces a jointless surface is easiest to make by applying the product twice. Apply by steel trowel a smooth coat to an area of approx.1-2 m² . Smooth the coating by sloping the trowel lightly and gently over the surface. After the first coat has dried, apply the second coat of Tunto Stone thinly.

Grind the surface immediately  (max.  after 15 min.) by pressing lightly with Tikkurila plastic float. If the float does not move lightly, there is too much of coating. Remove the excess coating with a steel trowel. Note! Too thick layer slows down the drying process and may cause the odor to stay longer.


Application by spraying e.g. with a plaster pump or a funnel sprayer

Apply by spraying with a low pressure from approx. 1 m distance in a circular motion along the surface. Smooth the coating by sloping the trowel lightly over the surface.  Uniform surfaces are sprayed  without interruption.

Note! Wet fillers like Presto Light Filler are suitable under Tunto Stone coating.  When using dry fillers, the filler has to be cement reinforced . Ventilate the area thoroughly prior to taking it in use.

Cleaning of tools
Remove excess coating from the tools back to the paint can to avoid clogging the drainpipe. Clean tools with water.
Maintenance instructions
The surfaces are cleaned with a damp brush or as dry cleaning using a vacuum cleaner.
Handle the surfaces gently during few days after the coating is applied as the product achieves its final hardness and durability after approx. one month in normal conditions.

Product consumption, when surface is...


Consumption varies depending on the surface to be treated and its condition. Absorption is affected e.g. by the surface roughness, moisture content level of timber and porosity. For example, log surface that has been untreated for a long time takes a lot more wood finish than a new surface to be treated.

When calculating the consumption, note that the consumption for round logs is 1.5 times higher than normal. Please also note the corner joints in the surface area.

Rounding up

As the filling rate is usually 90% (space for tinting), it is good to round up the liter amounts and reserve enough of the product so that the work is not interrupted unnecessarily, and colour will be even.
