In this guide, discover how to create facade mouldings—from their components (copings, friezes, capitals, etc.) to their implementation—so as to achieve a decorative result that meets your expectations.

Decorative elements

Create the decorative elements progressively as the render is being applied.

Application

First solution: moulded profiles

Prepare the installation of the profiles
- Mark the positions on the architectural facade to achieve a uniform moulding layout.
- Cut each profile to the required dimensions.
- Apply an even layer of adhesive to the back of the profiles using a notched trowel.
Install the profiles
- Position each profile and press firmly.
- Unroll the reinforcing mesh and embed it into the selected render or into webertherm PPE
- Note that moulded profiles are available in 9 models for window surrounds and string courses.

Second solution: layout design using organic finishing renders

Apply the base coat and mark out the layout
- Apply a coat of weber régulateur
- Mark out the layout on the facades.
- Protect the joints with adhesive tape (this is an important step for decorative treatment).
Apply the finishing render
- Apply the selected organic finishing render, then remove the adhesive strips before the render has fully dried.

Third solution: decorative finish using thick mineral renders, such as recessed joints.

Apply the render and transfer the layout
- Apply the render and create a scraped or floated finish
- Transfer the joint layout using an ochre chalk line
Form the recessed joint
- Adjust the strip tools according to the desired joint width.
- Form the joint while respecting the minimum back-of-joint thickness:
  - 10 mm for waterproofing renders
  - 5 mm for decorative renders
- Ensure the maximum joint depth does not exceed 10 mm.
- Note that facade moulding must be carried out carefully, as it directly affects the final appearance and quality of your decorative features.
