The 5 Biggest Mistakes in Glue Mixing – And How to Avoid Them

Proper adhesive mixing isn’t rocket science—but it’s not guesswork either. Even small errors in glue preparation can lead to:

❌ Poor bonding
❌ Clogged machines
❌ Increased waste
❌ Production delays

At TOPCORE, we help our clients avoid these problems by offering personalized mixing instructions and on-site assistance during first-time preparation. Here’s what we’ve learned over the years.

❌ Mistake #1: Incorrect Water Temperature

Using water that is too cold or too hot can negatively affect the solubility of ingredients, especially when preparing dextrin-based blends.
This can lead to inconsistent adhesive texture and reduced bonding performance during application.

✅ Always follow the recommended temperature range stated in your TOPCORE mixing instructions. This ensures optimal viscosity and performance.

❌ Mistake #2: Ignoring Ingredient Ratios

Too much filler, too little water, or inconsistent dosing can throw the entire recipe off balance.

✅ We provide step-by-step instructions tailored to your exact blend. All customers receive a custom mixing protocol for each formulation.

“You can have the best ingredients in the world, but if the mix is wrong, it won’t perform.” — Petr Červinka, Co-owner of TOPCORE

❌ Mistake #3: Wrong Mixing Speed

Many overlook the impact of mixing motor RPM. Too slow = incomplete activation. Too fast = excess air and foam.

✅ Our team helps calibrate your mixing equipment and define the ideal speed curve for your recipe.

❌ Mistake #4: Skipping Filtration

Unfiltered adhesive often contains undissolved dextrin residues or leftover impurities from the mixing equipment.
These contaminants can clog nozzles, disrupt flow, and cause unexpected machine downtime.

✅ Always filter the adhesive before use. A small filter can save you from hours of unplanned downtime.

❌ Mistake #5: No Final Quality Check

Even if you follow the process, it’s crucial to verify the result.
Glue that’s too thin, too thick, or unevenly mixed can create invisible issues until it’s too late.

✅ That’s why we recommend a simple exit control test for every batch. We’ll even show your team how to do it efficiently.
