# **How to Choose Fly Tying Varnish Thinners: The Right Product to Thin Your Varnish**
As an avid fly tyer, you know that achieving the perfect finish on your flies is crucial for durability and aesthetics. One of the key components in this process is **fly tying varnish**, which protects and enhances the appearance of your flies. However, sometimes the varnish can be too thick, making it difficult to apply smoothly. That’s where **varnish thinners** come into play.
Choosing the right thinner for your fly tying varnish is essential to maintaining the quality of your flies while ensuring ease of application. In this guide, we’ll explore how to select the best varnish thinner for your needs, focusing on compatibility, safety, and performance.
## **Understanding Fly Tying Varnish and Thinners**
Fly tying varnish is typically made from **epoxy, lacquer, or solvent-based resins**, each requiring a specific type of thinner. Using the wrong thinner can ruin the varnish, making it too runny or causing it to lose its adhesive properties.
### **Types of Varnish Thinners**
1. **Solvent-Based Thinners** – Ideal for traditional varnishes like head cement or lacquer-based finishes. Common solvents include **acetone, mineral spirits, and denatured alcohol**.
2. **Epoxy Thinners** – If you use epoxy-based varnishes, you’ll need a specialized epoxy thinner to maintain the chemical balance.
3. **Water-Based Thinners** – Used with water-based varnishes, these are less toxic but may not be as durable for heavy-duty applications.
## **Key Factors When Choosing a Varnish Thinner**
### **1. Compatibility with Your Varnish**
Always check the manufacturer’s recommendations before mixing a thinner with your varnish. Some brands, like **KyleBooker**, provide dedicated thinners designed specifically for their varnishes, ensuring optimal performance.
### **2. Drying Time & Viscosity Control**
A good thinner should adjust the viscosity without drastically altering drying time. If the thinner evaporates too quickly, it can leave bubbles or an uneven finish.
### **3. Toxicity & Ventilation**
Many traditional thinners contain strong solvents that require proper ventilation. If you prefer a safer option, consider **low-VOC or water-based thinners**.
### **4. Shelf Life & Storage**
Some thinners degrade over time, especially if exposed to air. Opt for products with stable shelf lives and store them in airtight containers.

## **Final Tips for Using Varnish Thinners**
– **Test First** – Always mix a small batch before applying to your flies.
– **Use in Moderation** – Too much thinner weakens the varnish’s protective qualities.
– **Clean Tools Properly** – Thinners can be used to clean brushes and bobbins after use.
