Double-Sided Mounting Tape for Aluminium

Need to bond aluminium without drilling holes or leaving visible screws and rivets? StickyLab offers high-performance double-sided mounting tape for aluminium for signs, trims, panels, fabricated components and a wide range of professional, trade and DIY applications.

Aluminium comes in many different forms and finishes, including bare, anodised, painted and powder-coated surfaces. Choosing the right mounting tape therefore depends on both the aluminium itself and the way the finished component will be used.

Which Double-Sided Tape Should I Choose for Aluminium?

The best mounting tape for aluminium depends on the surface finish, available bonding area, environment, load and whether the adhesive will remain visible after installation.

At StickyLab, our Heavy Duty Black and Crystal Clear mounting tapes provide options for different aluminium bonding requirements.

Our Crystal Clear Mounting Tape is particularly useful when the appearance of the finished aluminium component is important and the bonding area may remain visible.

The transparent construction helps create a more discreet fixing and can be useful for decorative aluminium, display systems and installations combining aluminium with transparent materials such as glass or acrylic.

Ideal for many applications including:

Decorative aluminium
Aluminium trims
Display components
Interior installations
Aluminium combined with glass or acrylic
Appearance-critical projects
Applications where a discreet fixing is preferred

The correct choice between black and clear tape should ultimately be based on the aluminium finish, the second bonded surface and the requirements of the installation.

Understanding Different Aluminium Surfaces

Not all aluminium surfaces are identical.

This is particularly important when choosing double-sided adhesive tape for aluminium, because the adhesive is bonding to the surface finish rather than simply to the material underneath.

Bare Aluminium

Bare aluminium can provide a suitable bonding surface when correctly prepared, but the surface should be clean, dry and free from oils, oxidation and contamination.

Anodised Aluminium

Anodising creates a controlled oxide layer on the aluminium surface. Because anodised finishes can vary, the actual surface should be assessed and prepared before adhesive bonding.

Painted Aluminium

When applying mounting tape to painted aluminium, the adhesive is effectively bonding to the paint coating.

The overall installation therefore depends not only on the tape but also on how securely the coating itself is attached to the aluminium underneath.

Powder-Coated Aluminium

Powder-coated aluminium is widely used for architectural components, signs, frames and fabricated products.

Different powder coatings can have different surface characteristics, so compatibility should be considered rather than assuming every powder-coated surface will behave identically.

For unfamiliar or critical surfaces, testing before the final installation is good practice.

Suitable Aluminium Mounting Tape Applications

High-performance double-sided tape for aluminium can be useful across many professional, commercial and DIY applications.

Common examples include:

Aluminium signs
Aluminium house numbers
Aluminium trims
Aluminium sheets
Display panels
Architectural aluminium
Fabricated components
Access panels
Exhibition displays
Aluminium kick plates
Decorative aluminium features
Retail displays
Information panels
Aluminium composite panels
Window and door trims

From sign making and fabrication to interior finishing and home improvement, mounting tape provides a convenient way to create a clean fixing without necessarily introducing visible mechanical fasteners.

Double-Sided Tape for Aluminium Signs

Aluminium is widely used for signs because it is lightweight, durable and provides a professional appearance.

Mounting tape can be particularly useful for aluminium signage because it allows the fixing to remain hidden behind the sign.

Potential applications include:

House numbers
Information signs
Directional signage
Office signs
Retail signs
Nameplates
Display panels
Exhibition signage

Where the tape is completely concealed behind the sign, Heavy Duty Black Mounting Tape will often be the natural choice.

Where the installation involves transparent components or the bonding area may remain visible, Crystal Clear Mounting Tape may provide a more discreet alternative.

Double-Sided Tape for Aluminium Trims

Narrow aluminium trims are another application where adhesive mounting can be particularly useful.

Drilling a slim trim can introduce visible fixing points and may be impractical where there is limited space for screws.

A suitably sized mounting tape can create adhesive contact along the length of the trim while keeping the fixing hidden.

Applications can include:

Decorative trims
Door trims
Interior finishing strips
Display trims
Architectural detailing
Aluminium edging

Choosing a tape width that fits comfortably behind the trim is important so that the adhesive does not remain visible around its edges.

Why Use Mounting Tape Instead of Screws on Aluminium?

Traditional aluminium installation often relies on screws, rivets, bolts or other mechanical fasteners.

For many compatible non-structural mounting applications, double-sided mounting tape for aluminium provides an alternative.

Clean Appearance

The tape remains between the bonded surfaces, helping eliminate visible screw heads and rivets from the face of the component.

No Drilling Required

For suitable applications, mounting tape can avoid drilling holes through the aluminium.

This can be particularly useful for decorative panels, trims and signs where appearance matters.

Bonding Across a Wider Area

Mechanical fasteners concentrate forces around individual fixing points.

Mounting tape instead creates adhesive contact along the areas where tape is applied, helping distribute the load across the bonded area.

Useful for Thin Components

Thin aluminium trims and panels may have limited space for conventional mechanical fixings. Mounting tape can offer a neat solution where sufficient bonding area is available.

How to Prepare Aluminium for Double-Sided Tape

Correct preparation is essential when applying double-sided tape to aluminium.

1. Identify the Aluminium Finish

Determine whether you're working with:

Bare aluminium
Anodised aluminium
Painted aluminium
Powder-coated aluminium
Another coated or treated surface

The surface finish can affect adhesive performance.

2. Clean the Bonding Area

The surface should be:

Clean
Dry
Free from dust
Free from grease and oil
Free from loose contamination

Aluminium components can carry oils or residues from manufacturing and handling, so don't assume a new component is automatically ready for bonding.

3. Prepare Both Surfaces

Remember that aluminium is only one half of the bond.

The material being attached to it must also be clean, compatible and properly prepared.

4. Apply the Tape Evenly

Apply the tape to the prepared surface without unnecessarily stretching it.

Avoid touching the exposed adhesive with your fingers.

5. Apply Firm Pressure

Firm, even pressure helps establish good contact between the adhesive and the aluminium surface.

Apply pressure across the complete taped area rather than only at isolated points.

6. Allow the Bond to Develop

Avoid unnecessarily disturbing or heavily loading the installation immediately after application. Pressure-sensitive adhesive bonds develop after the surfaces are joined.

Double-Sided Mounting Tape Sizes for Aluminium

StickyLab mounting tape is available in a range of widths and roll lengths, allowing you to select a size appropriate for the component and available bonding area.

Available widths:

5 mm
8 mm
10 mm
15 mm
20 mm
25 mm

Available roll lengths:

1 metre
3 metres
5 metres
10 metres

Narrower tape can be useful for aluminium trims and smaller components, while wider tape provides greater adhesive coverage where a larger bonding area is available.

The appropriate width should be determined by the application rather than simply choosing the widest tape available.

Black or Clear Mounting Tape for Aluminium?

Both options can have a place in aluminium bonding.

Aluminium Application	Heavy Duty Black	Crystal Clear
Painted aluminium	Excellent option	Application dependent
Powder-coated aluminium	Excellent option	Application dependent
Concealed aluminium signs	Recommended	Suitable
Aluminium trims	Excellent option	Excellent where appearance matters
Fabricated components	Recommended	Application dependent
Decorative aluminium	Suitable	Excellent option
Aluminium with clear acrylic	Suitable if concealed	Recommended where visible
Aluminium with glass	Suitable if concealed	Recommended where visible

The deciding factor isn't simply whether the aluminium is bare, anodised or coated. Consider the entire installation, including the second bonded material and whether the adhesive will be visible.

Can Mounting Tape Be Used Outdoors on Aluminium?

High-performance mounting tape can be suitable for many outdoor aluminium applications when correctly selected and applied.

However, exterior installations can introduce additional factors such as:

Temperature changes
Moisture
UV exposure
Wind loading
Movement between bonded materials
Size and weight of the component

Aluminium and the material bonded to it can also respond differently to temperature changes.

For exterior installations, consider the complete application rather than simply whether the tape will adhere to aluminium.

Common Mistakes When Applying Tape to Aluminium

Not Identifying the Surface Finish

Painted, powder-coated, anodised and bare aluminium should not automatically be treated as identical bonding surfaces.

Bonding Over Grease or Manufacturing Residue

New aluminium components can still carry contamination from manufacturing, handling or storage.

Clean the bonding area before installation.

Ignoring the Second Surface

A tape may bond well to aluminium but poorly to the material on the opposite side.

Both surfaces matter.

Using Too Little Bonding Area

The amount and position of tape should be appropriate for the component and application.

Loading the Bond Immediately

Avoid unnecessarily applying significant load immediately after installation. Give the adhesive bond time to develop.
