Mounting Methods & Fixings for Signage

Common Mounting Methods for Signage in New Zealand

3M VHB Tape (Very High Bond)

VHB tape is a strong, double-sided adhesive used widely for indoor signage. It bonds extremely well to smooth, clean surfaces such as ACM, acrylic, PVC, and painted walls. For smaller indoor panels, it offers a clean, hardware-free installation.

Best uses:

• Indoor acrylic panels

• PVC signs

• Light ACM panels

• Smooth interior walls

Important note:

For larger panels or any signage exposed to heat, sun, or weather, VHB must be paired with mechanical fixings (such as screws or rails). Thermal expansion and weight can cause adhesive-only installs to fail over time.

Mechanical Fixings (Screws, Caps & Plugs)

Mechanical fixings are the most reliable mounting method, especially outdoors. They’re suitable for ACM, timber, PVC, polycarbonate, and aluminium. Options include exposed screws, screw caps, colour-matched caps, or concealed fixings depending on the look you want.

Best uses:

• Exterior signage

• Shopfront panels

• ACM sheets

• Timber panels

• High-wind areas

Mechanical fixings provide structural strength where adhesives and tapes are not enough.

Standoffs (Spacers)

Standoffs create a premium look by lifting the sign off the wall by 12–25mm. They’re commonly used with acrylic signage and are ideal for reception areas, offices, and interior branding.

Best uses:

• Acrylic logo panels

• Reception signs

• Directional signs

• Feature wall signage

Standoffs require holes drilled through the sign panel, so they’re typically used only on rigid materials like acrylic or aluminium.

Rail Systems & French Cleats

Rail systems (or cleats) allow large panels to be mounted securely while keeping fixings hidden. They’re ideal for oversized ACM panels or signage that needs to be removable for maintenance.

Best uses:

• Large exterior panels

• Removable wall panels

• Multi-tenant building signage

• Heavy indoor feature panels

Rails provide excellent weight distribution and are mechanically reliable in NZ’s weather.

Silicone & Construction Adhesives

Silicone and hybrid construction adhesives are useful for bonding signs to less-than-perfect surfaces such as brick, concrete, or uneven paint. They’re often used together with screws to provide full support.

Best uses:

• Timber surfaces

• Masonry walls

• Uneven surfaces

Acrylic should be bonded carefully, as some adhesives can cause tension cracks. Silicone is also weather-sensitive and requires proper curing time before a sign can be loaded with weight.

Cable & Rod Suspension Systems

These systems are used for hanging signage from ceilings or mezzanines. They create a floating, architectural look and allow adjustable height.

Best uses:

• Retail hanging signs

• Menu boards

• Directional signs

• Acrylic or aluminium panels

Works beautifully in modern interiors where a suspended aesthetic fits the style.

Post & Panel Systems

Used primarily outdoors, post and panel systems anchor a sign into the ground. Posts can be steel, aluminium, or timber, with ACM or aluminium panels mounted between or onto the posts.

Best uses:

• Property signage

• Directional signs

• Parking signs

• Roadside signage

Post and panel mounting must account for wind load and soil conditions.

Choosing the Right Mounting for Each Material

Here’s a quick reference list:

• ACM: screws, rails, VHB (indoors or supported)

• Acrylic: standoffs, VHB (indoors only), hidden cleats

• PVC: VHB indoors, screws for stability

• Corflute: zip ties, frames, stakes

• Foamboard: temporary adhesive, removable fixings

• Polycarbonate: screws, rails

• Timber: screws + adhesive

For detailed material information, see our ACM Panel Signs and Acrylic Signage Guide.

Indoor vs Outdoor Fixing Considerations

Heat Expansion & Movement

• Acrylic expands significantly in heat

• PVC warps outdoors

• VHB tape softens in high heat

• ACM stays the most dimensionally stable

Mounting must account for material movement over time.

Surface Type

• Smooth walls → tape-friendly

• Brick or concrete → mechanical fixings

• Textured paint → mixed performance; usually requires screws

• Glass → VHB with primer or standoffs

Weight & Panel Size

• Large ACM panels need rails or screws

• Acrylic thicker than 10mm requires standoffs

• PVC is lightweight but can sag at large sizes

• Heavy timber panels need more fixings

Cost Differences (Simple Overview)

• VHB tape: low hardware cost, fast installs

• Screws/caps: low hardware cost, higher labour

• Standoffs: premium hardware

• Rails: mid–premium mounting system

• Suspension systems: premium aesthetic

What We Recommend for Common Projects

Reception & Office Signs

Acrylic with standoffs or PVC with VHB tape gives a modern, clean finish.

Exterior Shopfront Signage

ACM panels fixed with screws or rail systems for long-term durability.

Temporary or Event Signage

Promotional Corflute with zip ties or foamboard with temporary adhesive is quick and cost-effective.

Hanging Signs

Cable or rod systems for a floating installation that works well in retail or commercial spaces.

Summary: Choosing the Right Mounting Method

• Tape for small indoor signs

• Screws for exterior or heavy panels

• Standoffs for premium acrylic

• Rails for large or removable panels

• Hanging systems for suspended displays
