Chipperen is a distinctive facade finishing technique that involves applying a special mortar to a brick wall. Unlike traditional methods, which completely cover the brickwork, chipperen allows parts of the bricks and the masonry structure to remain visible through the mortar. This creates a unique, understated aesthetic that has gained popularity in recent years.
The term “chipperen” is derived from its association with renowned architect David Chipperfield, who employed this technique on two of his Berlin projects. Impressed by the results, the Dutch company Daas Baksteen (now Wienerberger) developed a specialized chipper mortar and popularized the method.
The Chipperen Process
Chippering is essentially a form of cementing, but with a much thinner and specialized mortar. This mortar is available in a wide range of colors and offers good water resistance and adhesion.
- Preparation: The wall must be clean and free from loose debris. In some cases, existing mortar may need to be removed.
- Application: The chipper mortar is applied to the wall using a trowel or other suitable tool. The thickness of the layer can vary depending on the desired effect.
- Finishing: The mortar is worked into the brickwork, ensuring that parts of the bricks and masonry remain visible. The final appearance can range from subtle to more pronounced, depending on the desired look.
Benefits of Chipperen
- Unique aesthetic: Chipperen offers a distinctive and modern appearance that can enhance the character of a building.
- Durability: The chipper mortar provides protection against weathering and improves the wall’s insulation properties.
- Versatility: It can be applied to both new and existing buildings, and the level of coverage can be adjusted to suit different styles.
- Maintenance: Chippered facades generally require less maintenance than traditional rendered walls.
Considerations and Challenges
While chipperen offers many advantages, it’s important to consider the following:
- Skill: Achieving the desired effect requires skill and experience. It’s essential to hire a qualified professional.
- Material quality: The choice of chipper mortar is crucial. Using a high-quality product is essential for long-term durability.
- Substrate compatibility: Chipperen may not be suitable for all types of brickwork. The substrate’s condition should be assessed before proceeding.
- Maintenance: Although generally low-maintenance, regular inspections are recommended to address any potential issues early on.
Chipperen vs. Other Facade Finishes
Chipperen is often compared to traditional techniques like rendering or cementing. However, it differs significantly in terms of appearance and process.
- Rendering: Involves applying a thick layer of mortar to completely cover the wall.
- Cementing: Similar to rendering but often used on internal walls.
- Chipperen: Offers a balance between the two, preserving the brickwork’s character while providing protection.
Conclusion
Chipperen has emerged as a popular and versatile facade finishing technique that can transform the appearance of a building. Its ability to create a unique and modern aesthetic, combined with its durability and low maintenance requirements, makes it an attractive option for both new construction and renovation projects. By understanding the process and considering the factors involved, homeowners and building owners can make informed decisions about whether chipperen is the right choice for their project.
