Wall Coatings

Wall coatings are one of the most demanded services we offer, thanks to our long experience and specialization.

Masonry coatings are an essential part of a building. They refer to the coating of the frame and walls with one or more layers of mortar. The main advantages of coating are improving the aesthetics of the exterior (or interior) of a building, reinforcing the thermal insulation and sound insulation, and they also ensuring maximum wall protection from severe weather conditions and the passage of time.

In a few words, the coating is essential for any construction for three main reasons:

  • Aesthetics: With the right craftsmanship, they offer a beautiful and smooth surface with the use of plaster.
  • Insulation: Plaster offers an additional, though small, protection against temperature changes and moisture.
  • Protection: Plaster prevents direct exposure of the concrete to severe weather conditions, offering significant protection.

At Smart Building our goal is to offer innovative solutions to homes and all kinds of buildings, ensuring unique results in every job we undertake.

The time needed to complete our coating work depends on the needs of each space. However, it usually takes 10 working days for a house of approximately 100m². It can even take longer under adverse weather conditions, such as very high or low temperatures.

What are coatings?

Coatings are the layers used as a coating of the cement, with the use of various protective materials such as plaster. The coating procedure protects the cement from the damage of time and intense conditions, thus increasing its life span. It also serves as an overall aesthetic intervention in the masonry of a building.

Wall coatings usually include one or more layers of plaster. The greater the thickness of a coating, the more protection it provides to the masonry of the building. It is therefore easy to understand why these tasks are a key part of home construction.

In metal/steel constructions, lime is not used in the coating mortar due to its corrosive effect. In these cases, a suitable bentonite admixture (sealagon type) is used, which has the properties of lime without, however, causing corrosion to the steel.

Wall coatings - phases

The phases involved in the manufacture of coatings include the addition of three layers, namely the preparation layer, the mud layer, and the marble layer. These layers must be applied in turns, allowing each layer to dry completely. If not, then the next layer will crack.

A basic rule we apply to coatings is that each successive layer should be stronger than the previous one in order to provide optimal results. More detailed information about each phase and how each layer is applied can be found below.

Surface Preparation - Casting the First Coating Layer

The first layer of coating consists of sand, water, grey cement, and lime. An alternative to lime, as mentioned above, is bentonite which ensures even better results. Casting the first layer acts as a “guide” that determines the thickness of the next layer. The aim of this phase is to provide a strong grip before the mud phase follows. In addition, the glass mesh will strengthen the plaster against cracks from material discontinuities, contractions and expansions due to changes in temperature and possible small seismic vibrations.

Mud Coating

In the second phase of coating, we use a mortar consisting of sand, water, grey cement, lime, or bentonite as well as a sealing compound to ensure greater protection against moisture. This is a thicker layer than plaster and marble.

Finally, glass mesh is placed on the surface of the mud coating layer, offering significant protection against plaster cracks, as mentioned before. In order to create adhesion for the next layer, we make wavy lines at the end of the mud layering.

Marble Coating

The last phase of plastering is marble, a mortar of marble dust, water, white cement, and lime or bentonite. We smooth the final surface of the marble coating to offer the desired flat and smooth texture.

Interior Coating

Interior coatings are applied to the interior spaces of buildings. A key procedure here is choosing the plaster. To choose the ideal plaster we take into consideration three main factors:

  • The type of substrate to be covered (concrete, brick, old masonry, etc.).
  • The environmental conditions (spaces with high humidity, strong temperature differences, etc.)
  • The kind of effect we are looking for on the surface (smooth, grainy, graded, etc.).

Evaluating all the above, and thanks to the year-long experience of our staff, we offer the best coating in all our projects. It is actually the very choice of plaster that affects aesthetics, strength and durability of the final result and minimises future defects. We guarantee excellent, lasting results in every coating job we undertake.
