Decorative plaster is becoming a popular option for homeowners who want to give their walls some character and texture. "Lamb" is one of the most popular techniques. This technique gives any interior space a distinctive, rustic finish that resembles the fuzzy feel of a sheep’s fleece and adds coziness and warmth.

The simplicity of the "Lamb" plastering technique is what draws people in. It’s not necessary to be an expert to produce stunning outcomes. Anyone can create a work of art on their walls with a few simple tools and supplies.

This post will walk you through the "Lamb" plaster application process and provide helpful hints and tips to make sure your project turns out exactly as you had envisioned. Plastering is a rewarding and enjoyable way to improve the interior of your home, regardless of your level of experience.

Application

This kind of ornamental plaster is more commonly used to complete a building’s exterior walls. The facades of multi-story private homes, office buildings, schools, and hospitals are frequently adorned with its pebble structure. For "wet facades," plaster mixtures work well on expanded polystyrene and mineral wool.

"Lamb" is also utilized as an interior decoration in hallways, stairwells, and areas with significant cross-country traffic. If you want to give your interior walls this kind of texture, it is definitely appropriate for any wall in the house.

Plaster can be made from surfaces that come from:

• concrete and brick;
• cement and gypsum plaster;
• polystyrene;
• drywall;
• Plywood and OSB slabs, chipboard;

We will next examine the characteristics of the mixtures that can be chosen for plastering.

A quick and easy way to give your walls a distinctive textured finish that resembles the fleece of a woolly lamb is to apply decorative plaster called "lamb" plaster. Without the need for costly materials or specialized skills, homeowners can easily add character and depth to their interior spaces by turning plain walls into striking focal points.

Which composition to choose?

One type of environmentally friendly material is decorative plaster. One of the constituents—cement, acrylic, or silicone—is the linking element in its composition. The second ingredient gives the "lamb" its texture: stone granules, such as marble crumbs.

The amount of marble grain in the plaster composition influences the texture’s expressiveness, the layer’s thickness, the mixture’s consumption, and the application technique.

• 1 mm — suitable for machine application on large areas;
• 1.5 mm, 2 mm, 2.5, mm — the most common grain sizes, mainly used on facades for manual plastering;
• 3 mm, 4 mm — mixtures with this fraction size exist, but are rarely used.

Plaster of acrylic

The primary component, acrylic resin, provides the finished material’s layer with strength. It doesn’t mind the rain, sunshine, dirt, or extreme heat or cold.

Available for immediate use, packaged in 25–30 kg buckets.

Well-known brands include Prorab "Optima" and Bayramix "Palta."

If the plaster isn’t painted, you’ll need to either order color from a specialist or add it yourself before applying it. You can use antifungal and antiseptic additives.

The composition of acrylic plaster is very flexible. It can cover a variety of the building’s projecting ornamental features.

One distinguishing characteristic is the hardening rate. In order to avoid visible seams, you must work without taking extended breaks. Stir the remaining material in the bucket continuously until a uniform mass is achieved.

The finish is easy to maintain and long-lasting. This is a good choice for exterior work when installing a "wet facade" on polystyrene foam insulation, as well as for decorative plastering "under the lamb" inside the house.

Silicone concoction

Better performance is provided by silicone resin, the main component. This plaster is applied to mineral wool (basalt) facades.

Although the material costs more than acrylic plaster, it performs better.

Benefits of this kind

• durability, resistance to abrasion, frequent rains, service life up to 20 years;
• vapor permeability, tolerates moisture and high temperatures, does not form mold, fungus;
• the flexibility of the material does not allow the coating to change when damaged.

Combination of minerals

This kind of mixture is the least expensive for "lamb." Mineral chips are bonded together using cement as a base. granule size between 1.5 and 2.5 mm. Before being used, plaster is diluted with water and sold dry in 25 kg bags.

This type’s benefit is that the mixture can be stored in a dry room for a longer period of time. There is no difference in temperature.

Bolars "Optima" and Ceresit CT 137 are two manufacturers as examples.

Kindly take note! Dry mineral mixtures need to be painted again with facade paints because they turn white or gray after application. That is to say, plasterers and painters will need to be involved in order to finish the walls. This will lessen the benefit of the material’s low price and raise the cost of the work.

Preparation for plastering

The foundation for "lamb" plaster must meet the same specifications as any other kind of ornamental coating:

• the walls must be smooth, strong enough;
• cleaned from dust, efflorescence and other contaminants;
• unevenness and defects on the wall no larger than the grain size of the decorative plaster are allowed;
• porous, absorbent bases must be impregnated with a deep penetration primer, for example, Ceresit CT 17;
• then, under decorative plaster, the walls are primed with compounds such as Ceresit CT 16;

Application technology

The material can be applied in two ways: using a trowel or a cartouche gun for spraying. Let’s examine each plastering technique in more detail to see how the "lamb" texture is created.

Trowel

1. I apply the finished or mixed plaster with a spatula from the container onto a metal trowel.
2. Holding the tool at an angle to the wall of approximately 45°, apply the mixture in an even layer. Its thickness must be brought to grain size t.e. 1.5-2.5 mm. Align the applied layer until there is no more plaster on the trowel.
3. It is better to work in squares with an area of ​​1 – 1.5 m2, because the material sets in 15 – 20 minutes. During this time, it is necessary to level the “lamb” and do the grouting.
4. After application, the entire plastered surface must be rubbed with a plastic trowel – smoother to highlight the pebble texture. The tool is pressed against the wall with its entire plane and processed with a little pressure in a circular motion.
5. Then proceed to decorating the next section of the wall, repeating the entire technology.

Machine application

You can use a cartridge gun that is connected to a compressor to apply the "lamb" mechanically. This is the primary way that large-area building facades and stairwells at entrances are decorated.

1. The finished solution is placed in the gun tank.
2. Turn on the compressor and spray an even layer onto the wall surface.
3. There is no need to rub in the decorative material with this method of application, because.. for machine application, use plaster with a fine fraction of crumbs, and from the rubbing the texture obtained by spraying will be smoothed out, will become less expressive.

Consumption of plaster per 1 m2

One layer of plaster, the thickness of which corresponds to the grain size, is applied beneath the "lamb." The decorative mixture’s consumption will thus be directly influenced by this parameter.

• With a granule size of 1.5 mm, the consumption will be 2.5 kg / m2.
• With a size of 2 mm – the consumption will be 3 kg / m2.

The air temperature and the base’s moisture-absorbing capacity affect drying time. After 12 to 24 hours, the decor finally solidifies. The finish becomes impervious to precipitation after 24 hours.

"Lamb" decorative plaster is a great, simple way to add texture and individuality to your walls. Because of its simple application, it can be used by both professionals and do-it-yourselfers.

This plaster is a useful choice for a variety of interior spaces because it not only adds visual interest but also durability. Any room gains warmth and character from the "Lamb" technique’s natural patterns.

For those seeking a creative update to their home, "Lamb" plaster provides an easy-to-use yet highly efficient option. You can turn your walls into a work of art with the correct supplies and a little perseverance.
