Best Double-Sided Tape for Acrylic

Best Double-Sided Tape for Acrylic

Choosing the best double-sided tape for acrylic depends on what you're mounting, whether the acrylic is clear or opaque, where it will be installed and whether the adhesive will be visible once the project is finished.

Acrylic, often known by brand names such as Perspexยฎ, is widely used for signs, retail displays, information panels, protective screens and decorative features. For many suitable applications, high-performance acrylic foam mounting tape provides a clean way to bond acrylic without visible screws, brackets or drilled holes.

At StickyLab, we offer two main options: Heavy Duty Black Mounting Tape for strong concealed mounting and Crystal Clear Mounting Tape for applications where a discreet appearance is particularly important.

What Is the Best Double-Sided Tape for Acrylic?

For many acrylic applications, a high-performance acrylic foam double-sided mounting tape is an excellent choice.

Unlike thin general-purpose double-sided tapes, foam mounting tape provides a thicker adhesive layer that can help maintain contact between compatible surfaces and distribute the bond across the taped area.

The right option depends largely on whether the adhesive will be visible.

For opaque acrylic or concealed mounting:
Heavy Duty Black Mounting Tape is usually the better choice.

For clear acrylic or Perspexยฎ where appearance matters:
Crystal Clear Mounting Tape will usually provide the more discreet finish.

Heavy Duty Black Mounting Tape for Acrylic

Our Heavy Duty Black Mounting Tape is suitable for many compatible acrylic applications where strength, durability and concealed mounting are the priorities.

It is particularly useful for:

  • Opaque acrylic signs
  • Acrylic display panels
  • Information boards
  • Retail displays
  • Exhibition panels
  • Decorative panels
  • Plastic components
  • Concealed mounting applications

Where the tape is completely hidden behind the acrylic, the black construction provides a neat fixing without visible screws or brackets.

Crystal Clear Double-Sided Tape for Acrylic

For transparent acrylic, Crystal Clear Mounting Tape is often the more attractive option.

Because acrylic is transparent, a dark adhesive can remain visible through the material. Clear mounting tape helps reduce the visibility of the fixing and is particularly useful where the finished appearance matters.

Common applications include:

  • Clear acrylic signs
  • Perspexยฎ panels
  • Transparent information boards
  • Retail displays
  • Point-of-sale displays
  • Exhibition displays
  • Display cases
  • Decorative acrylic features

Black vs Clear Double-Sided Tape for Acrylic

The easiest way to choose between the two is to consider whether the adhesive will be visible after installation.

Application Heavy Duty Black Crystal Clear
Clear acrylic signs Suitable if concealed Recommended
Opaque acrylic signs Recommended Suitable
Perspexยฎ displays Suitable Excellent choice
Retail displays Excellent Excellent
Decorative transparent acrylic Less discreet Recommended
Concealed mounting Recommended Suitable
Appearance-critical applications Application dependent Recommended

Neither option is automatically right for every project. The acrylic, second bonding surface, load and environment should all be considered.

Does Double-Sided Tape Stick to Acrylic?

High-performance mounting tape can bond effectively to many properly prepared acrylic surfaces.

However, good surface preparation is essential.

The acrylic should be:

  • Clean
  • Completely dry
  • Free from dust
  • Free from grease
  • Free from fingerprints
  • Free from polish and other contamination

The material on the other side of the tape is equally important. A successful bond requires both surfaces to be compatible and correctly prepared.

Does Double-Sided Tape Stick to Perspexยฎ?

Perspexยฎ is a well-known brand of acrylic, so many of the same bonding principles apply.

High-performance mounting tape can be useful for many compatible Perspexยฎ applications, including signs, displays, panels and decorative features.

For clear Perspexยฎ, Crystal Clear Mounting Tape is particularly useful where you want the fixing to remain as discreet as possible.

For opaque Perspexยฎ or applications where the tape will be completely concealed, Heavy Duty Black Mounting Tape may be the better choice.

Why Use Mounting Tape Instead of Screws on Acrylic?

One of the biggest advantages of double-sided mounting tape is the ability to create a concealed fixing.

No Visible Screws or Brackets

The tape sits between the acrylic and the surface behind it, helping maintain a clean finished appearance.

This can be particularly useful for signs and display panels.

No Drilling Through Acrylic

Acrylic needs to be drilled carefully to reduce the risk of cracking or damaging the material.

For suitable applications, mounting tape can eliminate the need to drill through the acrylic altogether.

Clean Professional Appearance

Acrylic is often selected because of its modern, clean appearance.

Concealed adhesive mounting can help preserve that appearance without visible screw heads or brackets.

Bonding Across an Area

Rather than creating individual fixing points, mounting tape creates adhesive contact across the areas where it has been applied.

How to Prepare Acrylic Before Applying Double-Sided Tape

Correct preparation can make a major difference to adhesive performance.

1. Remove Any Protective Film

Many acrylic and Perspexยฎ sheets are supplied with a temporary protective film.

Do not apply permanent mounting tape over this film.

Make sure you're bonding to the actual acrylic surface.

2. Clean the Acrylic

Clean the intended bonding area thoroughly.

Remove:

  • Dust
  • Grease
  • Fingerprints
  • Oil
  • Polish
  • Other surface contamination

Allow the surface to dry completely before applying the tape.

3. Prepare the Other Surface

Remember that the acrylic is only one half of the bond.

Whether you're attaching it to metal, painted material, glass, another plastic or another compatible surface, that material must also be properly prepared.

4. Avoid Touching the Adhesive

After removing the tape liner, avoid touching the exposed adhesive with your fingers.

Oils from your hands can contaminate the bonding surface.

5. Position Carefully

Check the position of the acrylic before completing the bond.

High-strength mounting tape can become difficult to reposition once good adhesive contact has been made.

6. Apply Firm, Even Pressure

Apply firm pressure across the complete taped area.

Good contact between the adhesive and both surfaces is important.

7. Allow the Bond to Develop

Avoid unnecessary movement or significant loading immediately after installation.

Pressure-sensitive adhesive bonds develop after the surfaces have been joined.

Double-Sided Tape for Acrylic Signs

Acrylic signs are one of the most popular applications for clear and black mounting tape.

Potential uses include:

  • House signs
  • Office signs
  • Door signs
  • Directional signs
  • Information panels
  • Retail signage
  • Nameplates
  • Decorative signs

For a clear acrylic sign, Crystal Clear Mounting Tape will usually be preferable where the adhesive can be seen through the sign.

For an opaque acrylic sign where the fixing remains hidden, Heavy Duty Black Mounting Tape is an excellent option.

Before mounting any sign, consider its dimensions, weight, available bonding area, substrate and whether it will be installed indoors or outdoors.

Double-Sided Tape for Acrylic Displays

Acrylic is widely used throughout the retail and exhibition industries.

Mounting tape can be useful for many compatible:

  • Point-of-sale displays
  • Product displays
  • Information panels
  • Exhibition stands
  • Promotional displays
  • Display cases
  • Decorative panels
  • Retail fixtures

Clear mounting tape can be especially useful when the transparency of the acrylic forms part of the design.

Choosing the Correct Tape Width for Acrylic

StickyLab mounting tape is available in a range of widths:

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

Roll lengths are available in:

  • 1 metre
  • 3 metres
  • 5 metres
  • 10 metres

For narrow acrylic trims or small components, a narrower tape may provide a neater fit.

Larger signs and panels may benefit from greater adhesive coverage where sufficient bonding area is available.

The correct width depends on the component and application rather than simply choosing the widest tape.

Can Double-Sided Tape Be Used Outdoors on Acrylic?

High-performance mounting tape can be suitable for many compatible exterior acrylic applications when correctly selected and installed.

Outdoor applications introduce additional factors including:

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

For larger signs, overhead installations or applications where failure could create a safety risk, the complete fixing system should be properly assessed.

Common Mistakes When Applying Tape to Acrylic

Bonding to the Protective Film

Always remove temporary protective film from the intended bonding area.

Otherwise, you're bonding the tape to the removable film rather than the acrylic.

Using Black Tape Where It Can Be Seen

Black mounting tape may be clearly visible through transparent acrylic.

For appearance-sensitive installations, Crystal Clear Mounting Tape is usually the better choice.

Not Cleaning the Surface

Fingerprints, grease and contamination can interfere with adhesion.

Clean both bonding surfaces before installation.

Using Too Little Tape

A few small pieces may not provide sufficient bonding area for a larger component.

Consider the size, weight and application when deciding how much tape to use.

Forgetting About the Other Surface

The tape needs to bond to two surfaces.

Even if it bonds extremely well to acrylic, the complete installation can still fail if the second surface is unsuitable or poorly prepared.

When Should Mounting Tape Not Be Used Alone?

Double-sided mounting tape is useful for many acrylic projects, but it should not automatically be used as the sole fixing method for every installation.

Extra consideration is required for:

  • Very heavy components
  • Large exterior panels
  • Overhead installations
  • Safety-critical applications
  • Poor or unstable substrates
  • Applications where failure could cause injury or significant damage

Where appropriate, use a suitable mechanical fixing method or follow the component manufacturer's installation requirements.
