Maximizing Efficiency: Tips for Properly Using and Storing Spray Adhesives

Publicado por Eli Koppel en

When it comes to perfecting your screen printing art, selecting the right spray adhesive often makes a world of difference. Despite appearing to be minor players, these adhesives add significant value to the overall printing process, influencing the quality of prints and the efficiency of the process. 

This article lays down a comprehensive guide to navigating the world of spray adhesives. From understanding their various bonding strengths to best practices for applying them and troubleshooting common issues, we leave no stone unturned.

Selecting the Right Spray Adhesive for Screen Printing

Screen printing is an artistic process where minor factors can significantly influence the overall output. Screen printers should understand that spray adhesives vary across the spectrum, impacting both the quality of your print and the efficiency of your operation.

Bonding Strength

The first fundamental consideration in making the right adhesive selection is understanding the concept of bonding strength. Bonding strength can be visualized as the cohesive power the adhesive offers. 

For instance, high-strength adhesives, as the name suggests, provide a firm and resilient bond, adhering closely to weighty fabrics. They work wonderfully if you're dealing with robust materials or your work necessitates a steadfast grip. 

However, bear in mind that these high-strength adhesives trade off some flexibility; once they grip onto a surface, repositioning can become a demanding task.

Drying Time & Repositionability

The drying time of a spray adhesive is another critical factor that deserves attention. A faster drying adhesive might seem like a boon for those wanting to speed up the process. However, remember that a quick-drying adhesive gives a smaller grace period for adjustments before it sets. 

If you're someone who prizes speed over precision, swift-drying adhesives could be your go-to option. However, for tasks demanding meticulous alignment and positions, adhesives that offer a longer drying time enabling repositionability might be a better choice.

Variety of Choices

The adhesive market offers an extensive variety of choices, catering to the diverse needs of screen printers. Every screen printing project is unique and might require specific types of spray adhesives. 

That means that as a screen printer, you must arm yourself with detailed knowledge about various adhesive types and their applications. Being well-informed will help you select the most suitable spray adhesive that marries well with your project specifications.

Experiment and Evolve

Screen printing, by nature, entails constant learning through experimentation. When it comes to spray adhesives, this fact remains true. So, don't hesitate to think outside of the box. 

Go ahead and experiment with different adhesives, application techniques, and methods until you discover what works best for your distinct practices and style. Remember, the ultimate aim is to enhance your work efficiency and final print quality, and finding the right spray adhesive is a significant step in that direction.

Preparing Your Surface for Adhesive Application

The key to a strong bond is starting with a clean surface. Any dust, oil, or residue can interfere with the adhesive's ability to stick.

Your first step should be to wipe down your screen printing surface using a lint-free cloth. This helps remove any loose particles that could weaken the bond of your spray adhesive.

If you're dealing with more stubborn contaminants like grease or old glue, consider using an industrial-grade cleaning solution. Just make sure it's safe for use on your specific material and fully dry before applying adhesive.

Drying Time Matters

Rushing into application without letting the surface properly dry can lead to problems down the line. The residual moisture might cause poor adhesion or even create bubbles in your print work.

A wait time of about 10-15 minutes after cleaning usually does the trick but double-checking never hurts. Use this pause wisely: get yourself ready and prepare other necessary supplies so that when it’s time, everything goes smoothly.

Surface Roughness Plays A Role Too

Certain surfaces may need some roughening up before applying adhesive - think sandpaper on wood. It creates small grooves where our trusty spray adhesive loves hiding out leading to better grip.

Remember – preparation makes perfect.

Best Practices for Applying Spray Adhesive

When utilizing spray adhesives in screen printing, a couple of hints can be very advantageous. First off, always shake your adhesive can well before use. This mixes up the ingredients and ensures an even application.

Keep a distance of about 6-8 inches between the nozzle and the surface when spraying. Too close, you risk over-spraying; too far away leads to uneven coverage.

A light coating is often more effective than one heavy layer. So apply multiple thin layers instead of going thick right from the start. Wait for each layer to become tacky before applying another one. Spraying in a sweeping motion rather than static sprays helps distribute adhesive evenly across surfaces. 

Beyond that, don't forget to clean up. After every use, invert your spray can and give it short bursts until only gas comes out. This prevents clogging for future applications - an easy trick that prolongs the lifespan of your adhesive cans.

Safe Handling and Use of Spray Adhesives

Safety is key when working with spray adhesives. These products are powerful tools but they require careful handling.

Proper Ventilation Is Crucial

You need to make sure your workspace has enough fresh air flowing through it. Without proper ventilation, inhaling the fumes can cause dizziness or headaches.

The Right Protective Equipment Matters

Wearing gloves will help protect your skin from potential irritation caused by direct contact with the adhesive. It's also smart to wear a mask that filters out particles and vapors while you're spraying.

Prioritize Safe Storage Practices

Spray adhesives should be stored in cool, dry places away from high temperatures or open flames. Remembering these safety recommendations will help prevent accidental fires and prolong the life of your product.

Troubleshooting Common Issues with Spray Adhesives

Even the best of us face challenges when using spray adhesives. It's like trying to make pancakes for the first time; it can get messy. Let's explore some common issues and how to solve them.

Weak Bonding

A weak bond is often a sign that you didn't use enough adhesive or your surface wasn’t properly prepared. Ensure your display is unsoiled and devoid of dust or oil before affixing adhesive. Sometimes, changing up the type of adhesive can also help strengthen the bond.

Residue Buildup

If there’s more glue residue on your hands than on the screen after a print run, chances are high that too much adhesive was used. This situation calls for moderation - less really can be more.

Clogging Issues

Clogs in spray adhesives are like traffic jams: they stop everything. But don't fret - most clogs occur because of buildup at the nozzle which can be easily fixed by soaking it in warm water.


The journey to mastering the use of spray adhesives in the screen-printing realm requires both knowledge and practice. Understanding your project's precise needs will guide your choice and, with the key insights provided in this article, you can confidently prepare your surfaces, apply, and handle spray adhesives safely. 

Whether you encounter weak bonding, residue accumulation, or clogging issues, rest assured that corresponding solutions are at your fingertips. Always remember the fundamental rule to continually experiment and learn, keeping in mind that perfection is born out of practice. Happy screen printing!
