Photo Corners vs. Glue: An Expert’s Breakdown of Mounting Methods

Hi, I’m Alex Morgan, Lead Product Strategist at SENDA Stickers. Early in my career, I consulted for a client who had spent months creating a beautiful family history scrapbook for an anniversary. Years later, they opened it to find many of the photos stained with ugly yellow lines, some even peeling away from the page. The culprit? A common, everyday glue stick they thought was harmless.

This is a story I’ve seen play out countless times. The choice of how you affix a photograph to a page is one of the most critical, yet frequently underestimated, decisions in the entire preservation process. It’s a choice between a professional, reversible system and an unpredictable, often damaging chemical reaction.

Let’s break down the real-world differences.

The Professional Standard: Archival Mounting Systems (e.g., Self-Adhesive Corners)

When professionals talk about mounting, we think in terms of systems that are safe, stable, and reversible. Self-adhesive photo corners are the quintessential example of such a system.

Key Strategic Advantages:

• Absolute Photo Safety: This is the paramount advantage. Archival-quality corners, like those we engineer at SENDA, are made from chemically inert materials like polypropylene. They create a protective pocket, meaning no adhesive ever touches the photograph itself. This completely eliminates the risk of chemical leaching or acid migration.
• Reversibility & Flexibility: In archival science, the ability to undo an action without causing damage is a golden rule. Photo corners allow you to easily remove, replace, or re-scan a photograph at any time, leaving the original print completely unharmed.
• Workflow Efficiency: From a practical standpoint, the peel-and-stick application is clean, precise, and incredibly fast. For projects involving hundreds of photos, this efficiency translates into significant time and labor savings, while ensuring a uniform, professional result every time.

Considerations:

• Initial Cost: The per-unit cost is higher than a bottle of craft glue. However, I always frame this not as a cost, but as an insurance premium against the irreversible damage that cheaper methods can cause.
• Application Scope: They are purpose-built for mounting photos, prints, and similar flat documents. They are not designed for heavy, three-dimensional objects.

The Common Pitfalls: Everyday Adhesives (Glues, Tapes, etc.)

This category includes everything from the glue stick in your desk drawer to double-sided tape and various liquid craft glues. While versatile, they introduce significant risks from a preservation perspective.

Inherent Risks & Drawbacks:

• The Chemical Danger: This is the most critical flaw. The vast majority of common adhesives are not archival-safe. They contain acids and other chemicals that will, over time, off-gas and leach into the paper fibers of your photograph. From my experience, this is the leading cause of yellowing, embrittlement, and staining.
• The Permanence Problem: Most glues are designed to create a permanent bond. This makes it nearly impossible to safely remove a photo once it has been mounted, eliminating any possibility of future conservation or digitization. Attempting to do so often results in tearing and delamination of the photo itself.
• Application & Mess: Liquid adhesives can be messy, seep out from the edges, and cause buckling in both the photo and the album page. Glue sticks can apply unevenly, leading to lumps and eventual bond failure.

My Professional Recommendation: It’s a Matter of Risk Management

When a client asks me which method to use, my answer is always framed around the value of the item being mounted.

• For Irreplaceable Heirlooms, Client Work, or Any Photograph You Value: The choice is unequivocally an archival mounting system like SENDA Stickers Photo Corners. The slight increase in cost is negligible compared to the value of the photograph and the guarantee of its long-term safety.
• For Temporary, Non-Critical Crafts (e.g., a child’s school project): A standard adhesive might be acceptable, but it should never be used for anything you intend to keep for more than a few years.

Ultimately, this isn’t just a choice between two products; it’s a strategic decision about how you manage the risks to your most irreplaceable assets. For a broader view on creating a safe environment for your collection, I highly recommend our Definitive Guide to Photo Preservation.
