TLDR

Mounting adhesive is a common supply needed for mounting prints, posters, signs, decals, and more. In this blog, we discuss some of the most common mounting adhesive types from a high-level, to help you get a more comprehensive understanding of these products so you can make the best buying decision.

Ever found yourself stuck in a sticky situation, looking for the best adhesive for mounting photos, posters, and more? The type of adhesive you use will vary greatly depending on the materials you are using, the end display needs, and other variables. So how do you choose the right one? In this blog we will walk you through the different kinds of mounting adhesives so you can determine the most effective option for your unique needs.

Adhesive Types for Mounting

The adhesive you choose can make or break your project when mounting. This specialized glue has two layers of adhesive separated by a carrier film. It’s designed to securely attach various materials to surfaces, making it the go-to-solution for everything from wall graphics to photo displays. There are two main types: heat-activated and pressure-sensitive adhesive.

Heat Activated Adhesive

Heat activated adhesives are your go-to for a strong, permanent bond. They’re activated by heat and pressure, usually through a specialized mounting press. Once activated, they form a secure bond between the material and the substrate.

These adhesives are fantastic for projects requiring a long-lasting hold, like mounting photographs or artwork you want to preserve for years. You can also use them for mounting high-quality prints. The downside is that you need specialized equipment to activate them.

Pressure-Sensitive Adhesive

On the flip side, pressure-sensitive adhesives are perfect when you need a little more flexibility. They work by applying pressure, so they’re also user-friendly. You can use them for both permanent and temporary applications. 

They’re useful for temporary displays, safety labels, wall graphics, or any project you might want to reposition to perfection. Therefore, they’re often the best adhesive for poster mounting. 

They’re also great for picture framing. Simply lay the picture face down, apply the adhesive evenly on the back, carefully place it on the frame’s mat board or backing, and apply pressure. Voila! Your picture is framed and ready to display.

While it’s easy to use and repositionable, it may not be as durable as heat-activated adhesives. So it’s not ideal for projects that need a permanent hold.

The Technology to Use when Applying Adhesives

The tools you use can be just as important as the adhesive itself in completing a successful project. Using the right technology for your adhesive ensures the best end result.

Roll Laminator

First up is the roll laminator, a versatile machine that uses rollers to apply adhesive films to various substrates. You can use a hot roll laminator to activate heat-activated adhesive as it passes through the rollers for a secure bond. A regular roll laminator uses pressure alone for pressure-sensitive adhesives, making it a flexible option for different projects like banners and posters.

Vacuum Press

A vacuum press is a specialized piece of equipment that uses heat and vacuum technology to apply even pressure across the material and substrate. It’s particularly useful for heat-activated adhesives. You can also use it with pressure-sensitive adhesives without heat to achieve a strong bond. This technology is best suited for precise projects, such as fine art mounting or archival projects.

Color Options Available

While it may seem like a minor detail, your adhesive color can impact the final look of your project, especially when it comes to transparency and background hues. Choosing the right color can add that extra touch of professionalism and aesthetic appeal that makes your work stand out.

Clear

Clear mounting adhesive is transparent, so the colors and details of your material can shine through without any color interference. It’s an excellent choice for projects where you want the mounted object to be the sole focus, such as transparent window graphics or fine art displays.

Clear adhesive offers a clean, professional finish, so it’s the best adhesive for mounting photos in which you don’t want any background distraction.

White Back

White back adhesive offers a solid, opaque white background that can enhance the vibrancy of your mounted materials. The white background is like a built-in reflector that makes your images appear brighter and more vivid. So it's useful when working with translucent materials, darker backgrounds, on floors or windows, or when you want to add that extra pop to your colors. 

Adhesive Properties

The adhesive properties can significantly impact your project's longevity, appearance, and success. Let’s compare four different properties to help you make an informed decision and get the results you’re looking for.

Carrier Free

Carrier-free adhesives come without a carrier film for a direct bond between the adhesive and material. They’re useful when you need a thinner, more flexible bond.

The adhesive conforms more closely to the material, providing a sleek, streamlined finish that makes them ideal for projects like vehicle wraps or curved surface applications.

High Tack

High tack adhesives offer a strong initial grip that strengthens over time, so they’re great for projects that require an immediate, permanent bond. They’re especially useful for working with heavier or more textured materials that need a strong hold right off the bat. Think of projects like outdoor signage or heavy photographic prints. High tack adhesives keep them put, even in challenging conditions.

Permanent

Permanent adhesives are designed for long-lasting applications where the bond is meant to endure over time. They’re your best bet for projects like permanent outdoor displays or archival framing. 

Removable

Removable adhesives provide a strong bond that can be easily removed without damaging the surface. Their flexibility is incredibly handy for temporary displays, seasonal decorations, or any project in which you anticipate future adjustments. They’re the best option when you want to change out displays without a hassle.

Choosing the Right Adhesive for Your Next Project

There’s a lot to consider when choosing a mounting adhesive. From the type to the  technology used for application and even the color and properties, each factor can significantly change your project.

So, how do you choose the right one? Consider your project needs — whether permanence, flexibility, transparency, or an immediate bond — and you’ll be well on your way to picking the perfect adhesive for a successful project.
