Can I Mix Small Batches of Epoxy Adhesive? Tips & Guidance

Mixing small batches of epoxy adhesive is entirely possible and often necessary for quick repairs or detailed tasks, but care is needed to ensure reliable results.

Precision Matters: Getting the Ratio Right

The most important rule, whether making a large or small batch, is to maintain the correct mixing ratio as specified for your epoxy adhesive. Even slight deviations can prevent the product from hardening properly. Many two-part epoxies require a 1:1 ratio by weight or volume, but always check your product instructions.

Using products like the “Klebfix” – Two-Component Fast Epoxy Glue 2K, the dosing syringe ensures accurate, equal dispensing of both components, even in tiny amounts.

Mixing Tools and Techniques for Small Quantities

When working with small batches, use precise measuring implements such as graduated mixing cups, syringes, or pipettes. Mix thoroughly and scrape the container’s edges to avoid unmixed material, which could affect the cure. Mixer nozzles, such as those designed for 50ml cartridges, can help achieve a consistent blend in even the tiniest applications.

Use clean tools for each batch.
Mix only what you can use within the working time to avoid waste.
Mix slowly to minimise bubbles.

When Small Batches Matter Most

Small batch mixing is particularly important for detailed repairs, touch-ups, or projects requiring tight control over the amount of adhesive applied. It’s also ideal when working on multiple small items or intricate assembly work, where using a large batch would lead to product waste or premature curing.
