Types of house rendering

Rendering systems are the most popular way to finish external walls stylishly and inexpensively. When choosing the right exterior render finish, it is necessary to adjust it to the surface and pay attention to a given solution. It so happens that not every render can be used in the same place. What is worth knowing about rendering projects? What properties do they have? We suggest everything worth knowing about types of render.

Types of rendering

We can paint the exterior walls of the facade with paint, clad them with clinker, choose “bare” brick or just bet on an elegant exterior monocouche render. Which one you decide on when rendering a house is also influenced by many other factors, such as:

  • Home environment (you use different render in a coastal area with high humidity, and other renders, for example, in a building next to a busy road);
  • Exposure to sunlight or wall shading;
  • Type of external wall insulation used.

Traditional renders

They are usually applied to one- and three-layer walls or used for the so-called renovation of old render. In addition, as for the properties of this type of render – it is characterized by excellent vapor permeability but requires painting. In the case of thick-coat rendering system, we distinguish:

Cement rendering

Cement render is difficult to work with, but is characterized by high strength and weather resistant – therefore cement renders are recommended for use in areas exposed to mechanical damage and moisture;

Cement-lime render

They are easier to apply, and characterized by greater vapor permeability, but are less durable and resistant to moisture than cement plasters;

Lime rendering

Nowadays they are used very rarely – they are not very resistant to damage, for that they are suitable for application on old render.

Thin-coat renders

They are one of the most popular ways to finish a building. Although it serves mainly an aesthetic function, many thin-layer renders also work well as wall protection. Their advantage is their versatility – they can be used on two-layer walls, as well as on finishing masonry surfaces.

You can find several types of thin-layer renders on the market, including:

  • mineral render – that is, extremely resistant, durable and coloured render, which is used especially in harsh conditions; its composition includes cement and polymer render, which positively affect the adhesion of the render;
  • acrylic render – acrylic rendering is a very durable thin-layer render that is flexible and resistant to any cracks; acrylic modern renders are easy to apply, plus they are available in many different colors; their undoubted advantage is the richness of their structures;
  • acrylic-silicone render – these are acrylic renders that have been enriched with silicone; they are vapor-permeable, and resistant to atmospheric agents;
  • silicone renders – they are characterized by excellent quality and all the advantages of mineral, acrylic, and silicate renders; they excel at excellent resistance to dirt and the possibility of installation even at very low temperatures. What’s more, such renders are also excel at self cleaning properties.
  • silicate rendering – they are the lowest water vapor permeability, and are not susceptible to moisture and destructive atmospheric conditions, such as heavy rains; they are resistant to attack by mold or other microorganisms; they are flexible, so it is worth using them where small cracks appear, which we can observe in traditional cement render;
  • silicate-silicone house rendering – this is a more refined version of silicate plasters. They are produced based on silicone resins and silicate binders; they are very resistant to adverse weather conditions and the mold or algae growth.
