Wapsi Head Cement Water Based – Thin, Non-Flammable Fly Tying Cement

Overview

Wapsi Head Cement Water Based is a staple on every fly tyer's bench, designed to help heads take shape with minimal fuss. The water-based formula is intentionally thin, allowing it to flow into thread wraps and delicate materials for a clean, controlled seal. It ships ready to use and can be lightly thinned with water. The product is non-flammable and dries fully overnight, giving you time to refine your pattern before the head sets. When cured, it won't dissolve in water, making it a practical choice for patterns you fish in various conditions. For a natural look, apply several ultra-thin coats to avoid an overly shiny head.

Why choose water-based vs. solvent-based cements?

Water-based head cements provide a gentler option that still supports a solid finish. The thin viscosity helps the cement penetrate thread and other tying materials, which is especially helpful on standard dry flies and nymphs, as well as on salmon flies and streamers where a precise head shape matters. This type of cement is ready to use, can be thinned with water, and is non-flammable, offering safer handling during long tying sessions. After curing, the cement resists water, which adds practical resilience to your finished flies. A note about sheen: achieving a natural look often means applying multiple light coats rather than a single heavy layer.

Key features (at a glance)

• Thin viscosity that penetrates thread and materials for a solid bond.
• Ready to use, with optional thinning via water.
• Non-flammable for safer handling on the bench.
• Dries fully overnight and remains intact when exposed to water after curing.
• Produces a natural head look with several thin coats; avoids an overly glossy finish.
• Better alternative to solvent-based cements for everyday tying tasks.

Practical tips for use

• Apply a small drop to seal heads on standard dry flies or nymphs; build up with thin coats as needed.
• For patterns that benefit from a glossier finish, a subsequent solvent-based gloss coat can be considered as a final step after head buildup.
• Use Head Cement Thinner to adjust viscosity or to revive cement that has thinned due to evaporation.
• Keep coats light to maintain a natural look; avoid thick layers that may appear obvious on the head.

In short, this water-based cement offers a flexible, ready-to-use option that supports reliable, durable heads without forcing a shiny finish. It pairs well with standard tying methods and serves as a practical choice for tyers seeking dependable performance with a natural look.
