Lime paste or Marmorino, plaster and whitewash for walls or ceilings

Natural, breathable lime, available in 56 shades from the IRIS color chart

Marius Aurenti lime is a mineral material whose timeless nobility lies in its ability to breathe through walls and the depth of its mineral pigments.

It is available as fine paste lime for fine coatings, brushed lime, whitewash and as a coating with a thousand marble asperities, marmorino, for interior and exterior walls.

It is applied over an interior and exterior lime primer suitable for preparing substrates before applying lime paste or marmorino.

On older buildings or in HQE construction, lime coating lets walls breathe thanks to gas exchange. This natural ventilation regulates humidity and improves air quality.

Processing lime paste

  • Can be smoothed or stuccoed with a metal trowel
  • Can be strung with a spalter
  • Can be applied as a whitewash

Supports

Lime paste and marmorino primer can be applied to these substrates:

  • New and old hydraulic binder-based wall coatings
  • Concrete walls
  • Plasterboard walls
  • Old organic or mineral paints and coatings
  • Substrates must be clean, sound and dry (free of oil and grease stains).

Lime paste and marmorino are then applied over this primer.

FAQ all about lime

Lime whitewash is a decorative wall finish based on lime and water with a few additives, used for coloring walls and creating graphic effects.

To produce the material needed for a lime whitewash, simply mix these three ingredients:

  • air lime powder or paste
  • water
  • color pigment

Before applying lime whitewash, it’s important to check the quality of the substrate. There’s no question of painting over a friable, porous, water-repellent or deteriorating substrate. The substrate must be smooth and even.

If the substrate is plaster, plasterboard or drywall, you must first apply a coat of primer, which as its name suggests, will enable the whitewash to block the base and cling to the surface. Then allow to dry and dust off.

Next, dampen the substrate and apply layer after layer of lime whitewash with a wide brush, sponge or spalter, alternating horizontal and vertical coats.

Aesthetic, tone-on-tone cameo, cloudy or marbled effects can be achieved by applying a lighter coat after a darker one, or vice versa.

To whitewash a wall, use air or hydraulic lime, in powder or paste form.

Air lime, based on calcium oxide and hydroxide, differs from hydraulic lime, based on aluminates, silicates and calcium hydroxide.

Air lime dries slowly on contact with air and is subject to a carbonation process, whereas hydraulic lime sets rapidly.

Lime milk

Lime milk is made up of 1 part lime to 10 parts water. A certain percentage of pigment is added to the volume of lime, depending on the desired color. So, for 100 grams of lime and 10% pigment, we’d add 10 grams of pigment. We also add a few drops of black soap, which acts as a wetting agent. It can be further diluted to obtain a patina.

Simple whitewash

A simple whitewash is made up of 1 part lime to 2 parts water, with the addition of a percentage of pigments and a touch of black soap, and around 2% casein or vinyl binder by weight of lime.

Brush on material

Raw whitewash is composed of a volume of lime, plus 20% of its weight in blanc de Meudon, 10% talc, and around 20% pigment, depending on the desired color. 10% of the lime weight can be added as a fixative, casein or vinyl binder. This type of whitewash is mainly used outdoors.

Lime coating is a mixture of lime powder or paste and sand.

If hydraulic lime is used, the rendering will dry faster than with air lime.

Mix approximately 1 part lime to 3 to 5 parts sand.

It is then applied in 3 layers:

  • The first coat is applied directly to the substrate, covering any irregularities (brick, stone, etc.).
  • The second coat, also known as “roughing”, is applied over the first after a week’s drying, and results in a flat surface.
  • The third, much thinner coat is applied 3 weeks after the second. Pigments can be added (10 to 20% of the lime weight) to modify the color of the rendering, and a little black soap to help distribute the pigment.

A lime wall has many advantages:

  • it looks great and can be tinted to your taste – Marius Aurenti offers it in 56 shades
  • it lets the interior space “breathe” thanks to its micropores
  • it acts as a humidity regulator
  • it acts as a sanitizing agent, preventing micro-organisms from growing and eating away at the wall
  • it’s strong and durable
  • a lime wall is a good thermal and acoustic insulator
  • on the outside, a lime coating protects the wall from the elements
  • used since antiquity, it is a sure bet in the construction industry, steeped in tradition.

Marmorino is a plaster just a few millimeters thick, a mixture of lime, marble powder, pigments and water. It has a glossy, marbled and luxurious appearance.

It’s also known as stucco marmorino, literally marble stucco.

Its origins date back to antiquity – it was already found in Pompeii – but above all to the golden age of the Republic of Venice in the 17th century, when it was used to clad the facades of majestic palaces.

Marmorino is applied to a wall layer by layer, after thoroughly wetting the substrate, which must be homogeneous.

The craftsman uses a stainless steel smoother or, for a rubbed effect, a polystyrene or sponge rubbing pad.

Marmorino can be used as a wall covering both indoors and out.
