Hi Bond Resin Additives, Rollers, Spreaders, Etc

Hi Bond Resin Additives, Rollers & Spreaders for Marine Fiberglass Work

When a fiberglass repair goes wrong, it usually isn't the resin that's to blame — it's everything around it. The additives, the application tools, the surfacing agents. That's exactly where Hi Bond has built its reputation. Resin additives, rollers, spreaders, and related supplies might seem like supporting players in a fiberglass job, but they're often the difference between a professional-grade finish and a frustrating do-over.

Hi Bond is a well-established name in the marine maintenance world, specializing in repair solutions for the most frequent boat issues and serving as a leader in manufacturing resins, thinners, thickening agents, and foam kits for boat care . Within the resin additives and tools category specifically, Hi Bond offers targeted products that address the practical challenges of working with polyester resins on boats and other fiberglass structures.

Key Hi Bond Products in This Category

• Wax-Sol (Surfacing Agent): A surfacing agent for polyester resins and gel coats, Wax-Sol creates a less tacky surface for easier sanding. This is a critical additive when applying a top coat or final layer of polyester resin — without a surfacing agent, air-inhibited polyester cures with a sticky surface that resists sanding and finishing.
• Cab-O-Sil (Fumed Silica Thickening Agent): A thickening agent additive for resins and gel coats, Cab-O-Sil is used to prevent sagging. This is especially valuable when working on vertical surfaces or overhead repairs where unmodified resin would run before curing.
• Fiberglass Resin Thinner (Styrene): Hi Bond's Fiberglass Resin Thinner is designed to improve brushability and enhance flow control to any polyester resin. A properly thinned resin wets out fiberglass cloth more effectively and helps eliminate voids in a laminate.

Why the Right Tools and Additives Matter

Resin additives are not optional extras — they're precision-engineering tools for controlling how resin behaves before, during, and after cure. Squeegees and spreaders help spread and evenly saturate the fabric, while rollers are also used to evenly saturate the fabric and help get rid of air pockets and excess resin. If you have too much resin, spots without resin, or bubbles in your finished product, you run the risk of a weak and broken result — using a good roller helps in creating a strong finished product.

Whether you are reinforcing a hull, patching a deck, or restoring fiberglass components, Hi Bond offers dependable performance trusted by boatyards and marine repair professionals. That same professional trust extends to their additive and tool lineup, where consistent formulation and straightforward application instructions make the work accessible whether you're an experienced boatyard tech or a hands-on boat owner tackling a first repair.
