5 Easy Steps To Plastering The Facade Of Your Home


What Is The Facade Of A Building?

The facade of a building is essentially its front or face, often referring to the exterior walls. This aspect of a building is not only crucial for aesthetic appeal but also plays a significant role in protecting the structure from various environmental factors.

Facade plaster serves as a protective coat for your home, safeguarding the exterior from moisture, driving rain, dirt, UV radiation, and frost damage. This protection is vital in preventing costly repairs down the line. Moreover, the vapor permeability of the exterior plaster is a key feature, allowing moisture from inside the building to escape to the outside, thus maintaining a healthy indoor environment.

So the facade of a building, enhanced with facade plaster, is not just about creating an attractive exterior but also about ensuring the longevity and durability of the structure by protecting it against environmental damages.

Why Plaster The Facade Of A Home?

Plastering the facade of a home offers numerous benefits that extend beyond mere aesthetics. While it undoubtedly enhances the visual appeal of a property, creating a uniform, smooth, and clean appearance, the advantages of facade plastering are far more comprehensive.

Firstly, applying plaster to the exterior walls serves as a protective shield against various environmental factors. It safeguards the underlying structure from moisture, driving rain, dirt, UV radiation, and frost damage[1][5]. This protective layer is crucial in preventing costly repairs that may arise from weathering and erosion over time. By investing in facade plastering, homeowners can significantly extend the longevity and durability of their property.

Moreover, the vapor permeability of exterior plaster is a key feature that contributes to a healthy indoor environment. It allows moisture from inside the building to escape to the outside, preventing dampness and mold growth within the walls[1]. This breathability is essential for maintaining a comfortable and hygienic living space.

In addition to its protective and moisture-regulating properties, facade plastering can also enhance the thermal insulation of a home. Modern plasters are designed to strengthen the thermal insulation, working in harmony with insulation materials to create an efficient building shell[5]. This improved insulation not only promotes a more stable indoor climate but also leads to potential energy savings by reducing the need for excessive heating or cooling.

The versatility of plaster as a facade material offers homeowners a wide range of design possibilities. With various textures, patterns, and color options available, plastering allows for creative freedom in customizing the exterior appearance of a home[5]. Whether aiming for a traditional or contemporary look, plaster can be tailored to suit individual preferences and architectural styles.

Lastly, investing in facade plastering can potentially increase the market value of a property[2]. A well-maintained and visually appealing exterior not only attracts potential buyers but also demonstrates the homeowner’s commitment to upkeep and quality. In a competitive real estate market, a meticulously plastered facade can set a property apart and contribute to its overall desirability.

So plastering the facade of a home goes beyond mere aesthetics. It offers a multitude of benefits, including protection from the elements, improved insulation, moisture regulation, design flexibility, and potential added value to the property. By recognizing the importance of a well-maintained facade and investing in quality plastering, homeowners can ensure the longevity, comfort, and appeal of their homes for years to come.

Context For The Five Steps

In these instructions, you will find out how you can plaster your home facade yourself – from the preparation to the correct way of working to the finishing coat.

When plastering, several layers of plaster are applied, whereby the following applies:

  • the more base plaster layers, the greater the strength. 
  • The final plaster gives the structure. 
  • The exact plaster system, i.e. the number and thickness of the layers or types of plaster, depends on the respective substrate or the type of brick. 

Our step-by-step instructions, therefore, refer to general brushing techniques. It is best to ask an employee in your local hardware store about the right plaster system for your specific facade.

Important: Make sure that the outside temperature is at least 5 °C during the entire work on the masonry

Step 1: Prepare The Substrate Of The Facade

At a glance

  • Brush the surface clean
  • Repair any cracks
  • Apply primer
  • Attach plaster profiles or rails

How To Do It

Stable plaster substrate must be clean, dry and free from loose parts and dust. Therefore, brush the free outer wall with a brush

In order to achieve an even surface, level out any imperfections with repair mortar if necessary. Pre-treat highly absorbent substrates such as aerated concrete or sand-lime brick with a primer by applying it generously with a painter‘s brush. It is important to repair cracks in the masonry before plastering.

When plastering an outside wall, it makes sense to use plaster profiles or plaster rails. These will help you to determine and maintain the plaster layer thickness, secure plaster edges and serve to complete the process smoothly. Fix the profiles to the wall with small amounts of setting mortar or plaster mortar at intervals of about 50 cm.

Step 2: Mix The Base Coat For The Facade

At a glance

  • Mix the base coat
  • Note the mixing ratio

How To Do It

Base plaster serves, among other things, as a primer on the masonry and as a plaster base for the topcoat. Mix the basecoat in a large mortar tub according to the manufacturer’s instructions. 

Ideally, you should use a drill with a whisk attachment for this. Mix the base coat until there are no more lumps.

Note: If the plaster does not stick to the facade later, either too much or too little water was added. Therefore, make sure that you comply with the specified mixing ratio.

Step 3: Apply And Smooth The First Layer Of Plaster To The Facade

At a glance

  • Apply plaster
  • If necessary, use the spray throwing technique
  • Smooth plaster layer
  • Working “wet on wet”.

How To Do It

Spread the plaster on the outside wall with a plastering trowel. Smooth it between two plaster rails to an even layer with a board or grapevine. Work “wet on wet”, i.e. always work on a wall without interruption and never mix more plaster than you can process in one session.

Advanced plasterers use what is known as the splatter technique when plastering: you throw the plaster at an angle from bottom to top against the wall with a quick, light twist of the wristIt is best to practice with smaller amounts beforehand.

Step 4: Let the facade plaster set and rub off

At a glance

  • Wait for dressing time
  • Rub off plaster layer
  • Let dry

How To Do It

Plan enough dressing time depending on the type of plaster. The dressing time is the time that the plaster takes to partially dry – i.e. it is a period of about 1.5 hours (depending on the type of plaster) that it should rest before the next stage. This is differentiated from the longer full drying time. 

Then rub the plaster with a trowel or sponge board. Then let the layer of plaster dry fully.

The rule of thumb for the base coat is: one day of drying time per 1 mm layer thickness. If the drying time is not observed, the plaster can become unstable or crack. Depending on the type of plaster, you may then process the second base plaster layer.

Step 5: Apply Finishing Plaster To The Facade

At a glance

  • Select finishing coat
  • Apply this thinly using the same technique

How To Do It

The finishing coat is thinner than the base coat but is applied using the same technique. You can choose the structure and color of the finishing plaster according to your taste: Different types of wall plaster are conceivable, including, for example, grooved plaster, felt plaster, scratched plaster, or decorative plaster such as disc plaster or rough plaster.
