Flexible Polyurethane Profile Application Guide
Flexible polyurethane profiles are decorative solutions for cornice, moulding and border applications on curved and round surfaces. The right model, surface form and installation method support a consistent finish.
What is a flexible profile and how does it differ from a rigid profile?
A flexible polyurethane profile is a decorative moulding produced with flexibility for curved surfaces.
The same design and cross-section may be considered in flexible or rigid versions; the main difference is the profile's ability to follow the surface form. Rigid profiles are used on straight surfaces, while flexible profiles can be installed along curved and circular lines.
Where are flexible profiles used?
Flexible profiles are used where cornice, moulding or border details are needed on curved and round surfaces.
- Decorative moulding and border applications on curved walls
- Cornice or moulding applications around round column shafts
- Oval and circular ceiling transitions
- Arch interiors and curved transitions
- Bay window surrounds and architectural surfaces with rounded lines
A flexible profile may also be considered for finishing details around curved wall panelling.
Which models can be made in a flexible version?
Flexible production is assessed according to the product model and cross-section.
The flexible version is made to order, and its suitability is stated in the proposal. A single design may be available in both rigid and flexible options; the final assessment considers the intended surface, model and cross-section together.
How far can a flexible profile bend?
The bending radius of a flexible profile varies according to its model and cross-section.
The radius of the installation surface should be provided during the proposal stage. This information helps assess whether the selected profile is suitable for flexible production and compatible with the surface.
How is a flexible profile installed?
A flexible profile is fixed to the surface by pressing it into place with PU-based mounting adhesive.
The profile should be pressed during installation to follow the surface form, and temporary support may be required where needed. The adhesive curing period should be considered according to 60–90 min clamping in the adhesive, full strength after 2–3 days.
Joints are finished with paintable acrylic filler. Silicone is not used when installing flexible profiles.
How is a flexible profile painted?
A flexible profile is painted with a suitable primer and water-based paint.
After surface preparation, primer is applied and allowed to dry. Water-based paint is used for the finish, with the profile surface and the characteristics of the installation space considered when selecting the paint.
