Edges and corners are not secondary details. They are part of the wall’s visual field. That is why it is important to decide early whether the design calls for wrapped corners, crisp reveals, accurate frames, or shadow gaps, then choose a system that can support that geometry without forcing finishing solutions that break the reading of the surface.

Some systems can support both interior and exterior conditions, but the decision should be based on exposure, detailing, protection, and the planned maintenance logic. The same material direction may work indoors and outdoors, but not necessarily through the same system or the same level of sealing.

In most interior applications, routine maintenance is relatively simple: gentle cleaning with a soft damp cloth and avoidance of strong or abrasive cleaners. On more sensitive surfaces, in wet areas, or in projects with defined maintenance requirements, both the cleaning routine and the protective system should be set in advance.

That depends on the finish direction, sheen level, protective system, and site conditions. For that reason, it is worth considering future repairs already during coordination, keeping the approved reference sample, and documenting the approved system. Where perfect continuity is especially critical, spare panels or an approved mockup may also be worth considering.

The timeline varies according to area, complexity, substrate condition, the number of aligned elements, and the duration of the sampling and approvals stage. For walls of this kind, the programme should always include time for samples, substrate preparation, and coordination between production and site phases.
