Hard as Hull Head Cement with Acrylic Polymers
Hard as Hull Head Cement with Acrylic Polymers is a specialized adhesive designed for fly tying in fishing. It combines the traditional strength of head cement with the added durability and flexibility of acrylic polymers. Here’s what you need to know:
Key Features:
1. Enhanced Durability
– Acrylic polymers provide a tough, flexible finish that resists cracking, even with repeated use or exposure to water.
2. Quick Drying
– Forms a hard, glossy coating that dries faster than traditional head cements, securing threads and materials efficiently.
3. Waterproof & UV Resistant
– Ideal for saltwater and freshwater flies, as it withstands harsh conditions without breaking down.

4. Versatile Application
– Works well for securing thread wraps, reinforcing fly heads, and coating synthetic/natural materials (e.g., deer hair, foam).
5. Clear & Glossy Finish
– Provides a professional, shiny appearance while protecting the fly’s structure.
How to Use:
– Apply a thin layer over thread wraps or fly heads using the built-in brush or a needle applicator.
– Allow to dry completely (typically a few minutes) before fishing or storing.
– Can be layered for added thickness if needed.
Comparison to Traditional Head Cement:
| Feature | Hard as Hull (Acrylic) | Traditional Head Cement |
|——————|————————|————————-|
| Flexibility | High (resists cracking) | Low (can become brittle) |
| Drying Time | Faster | Slower |
| Waterproofing| Excellent | Good |
| UV Resistance| Yes | Limited |
Best For:
– Saltwater flies (e.g., bonefish, tarpon patterns)
– Streamers and bass bugs
– Synthetic materials (EP fibers, foam)
– High-abrasion areas (fly heads, thread joints)
Popular Brands:
– Hard as Hull (by Wapsi or similar brands)
– Solarez Bone Dry (UV-cured acrylic alternative)
– Loon UV Clear (for UV-cure options)
If you’re looking for extreme durability without brittleness, this is a great upgrade from standard head cements. Would you like recommendations for specific fly types or techniques?
