When specifying colour matched fixings for façades and cladding systems, the type of finish applied to the fixing can be just as important as the colour itself. The finish affects how the fixing reflects light, how closely it blends with surrounding materials, and how consistent the façade appears once installed.

Architectural fixings such as colour matched screws and rivets are often repeated across the surface of a panel system. Even when the colour is correct, a difference in finish can make the fixing more noticeable than intended. Selecting the appropriate finish helps ensure the fixing integrates naturally with the surrounding material.

Mainline offers several coating options designed to match a wide range of façade systems and panel finishes. These include unpainted, standard, gloss, stone, metallic, and chameleon finishes. Each option serves a different purpose depending on the design requirements of the building.

Unpainted finish

Unpainted fixings are supplied without a colour coating. These are typically used where the fixing will not be visible, or where the natural metal finish is acceptable for the application.

In some façade systems, fixings may be concealed behind panels or architectural elements. In these cases, colour matching is not required, and an unpainted fixing provides a practical solution.

Unpainted finishes may be suitable for:

• Concealed fixings within façade systems
• Internal installations
• Applications where appearance is not critical
• Projects where the fixing will be covered by other materials

Although unpainted fixings can be appropriate in some situations, visible façade systems usually benefit from colour matched architectural fixings to maintain a consistent appearance.

Standard finish

The standard finish is the most commonly specified option for colour matched screws and rivets used in façade systems. It provides a balanced level of sheen designed to integrate with many factory finished cladding panels.

This finish works well for a wide range of architectural materials and is often selected when panels have a subtle surface reflectivity.

Standard finishes are typically chosen because they:

• Blend naturally with many façade panel finishes
• Provide consistent appearance across large surfaces
• Support accurate paint colour matching
• Work well for most architectural cladding systems

For many projects, the standard finish offers the most practical and visually consistent option for façade fixings.

Gloss finish

Gloss finishes provide a higher level of reflectivity and a smoother surface appearance. When façade panels or architectural materials have a noticeable sheen, gloss coatings can help maintain visual alignment between the fixing and the surrounding surface.

Because gloss coatings reflect more light, they can appear brighter under direct sunlight. For this reason, they are typically used when the panel system itself has a similar reflective quality.

Gloss finishes are commonly used when:

• Façade panels have a polished or reflective surface
• The architectural design requires a higher sheen finish
• Consistency with glossy panel coatings is important

Matching the reflectivity of the fixing to the panel surface helps maintain visual uniformity across the façade.

Metallic finish

Metallic finishes contain fine pigments that create a reflective or textured appearance similar to metallic architectural coatings. These finishes are often used when façade panels incorporate metallic pigments or specialised architectural coatings.

Matching metallic colours requires careful adjustment because metallic finishes can appear different depending on lighting conditions and viewing angles.

Metallic finishes are commonly used with:

• Metallic cladding panels
• Anodised style architectural finishes
• Aluminium composite materials with metallic coatings

Using metallic coated fixings helps ensure the fastening points integrate visually with the overall façade design.

Chameleon finish

Chameleon finishes create a colour shifting effect where the surface changes tone depending on lighting conditions and viewing angles. This type of finish is often used with specialist architectural panels designed to create dynamic visual effects.

Because chameleon coatings respond to light and movement, matching the fixing to the panel requires a carefully controlled coating process.

Chameleon finishes are typically used when:

• Façade panels have colour shifting coatings
• Architectural designs incorporate iridescent surfaces
• The appearance of the façade changes depending on viewing angle

By applying a similar finish to the fixing, the visual effect of the façade can remain consistent across the surface.

Stone finish

Stone finishes are designed to replicate the appearance of natural stone materials commonly used in façade systems. These finishes are typically specified when cladding panels feature stone-effect coatings, textured surfaces, or mineral-based finishes.

Unlike smoother coatings, stone finishes often have a more matte or lightly textured appearance. This helps reduce reflectivity and allows the fixing to blend more naturally with stone-effect panels.

Stone finishes are commonly used for:
• Stone-effect cladding panels
• Fibre cement boards with mineral finishes
• Façade systems designed to replicate natural stone
• Textured architectural surfaces

By matching both the colour and surface appearance, stone finish fixings help maintain a consistent and understated look across the façade.

Why finish selection matters for façade fixings

When hundreds of fixings are installed across a façade, even small differences in finish can affect the visual outcome of the building. A fixing with the correct colour but the wrong finish may appear darker, lighter, or more reflective than the surrounding panel.

By matching both colour and finish, colour matched architectural fixings can support the design intent of the façade and help maintain consistent visual lines across the building envelope.
