Let us figure out the epoxy for your boat kit
Epoxy is what holds it all together
Most epoxies require that you mix the resin and hardener and then add fillers to achieve the right consistency which can be fussy. System Three epoxy is application specific: one glue for adhering, another glue for laminating and coating, another for filleting, and so on. We have taken the worry out of your build by figuring out which epoxy you need and how much you will need to complete the project. The chart below will help you see what is typically included in a kit.
Excellent for small, quick gluing operations.
GelMagic is a toughened, non-sagging, two component, structural epoxy adhesive designed for superior bonding to wood and most porous materials. It is unique in that it starts as two self-leveling liquids, which form a soft, thixotropic, sag-resistant paste when mixed. Measuring is easily accomplished by either volume or weight. GelMagic requires no additional modification with fillers and can be applied to vertical and overhead surfaces without running, eliminating the mess and waste associated with other epoxies.
EZ-Fillet is a wood flour-filled two-part putty specifically designed for stitch-and-glue wooden boat construction. The resin (part A) is brick red in color while the hardener (part B) is a deep, dark green. A rich brown wood tone results when the two parts are combined indicating complete mixing. The putty thickens after mixing to form an easy to spread thixotropic compound which will not run or sag. EZ-Fillet has been designed for superior strength and workability and can be used by itself to create smooth cosmetic fillets or as a structural fillet when combined with fiberglass cloth.
SilverTip Epoxy is a medium-low viscosity, liquid epoxy resin system (we also use MAS) that has been optimized for coating and reinforcing fabric saturation in wood-composite boat building. It will outperform any other product in these applications. SilverTip Epoxy is designed for use with fiberglass, Kevlar®, Dynel® and graphite as well as on bare wood. It has superior wet-out characteristics with little tendency to foam or trap air.
Both the resin and hardener are nearly colorless and are used in an easy 2:1 volumetric ratio. SilverTip Epoxy cures to a brilliant blush-free film with either the fast or slow hardener eliminating secondary bonding concerns as experienced with other epoxies. The working time is longer than most boat building epoxies without extending cure time. The cured film is tough and resilient with better heat resistance than other epoxies cured at room temperature. Fillers, wood flour, and bulking agents can be combined with SilverTip Epoxy, however, we suggest using the other members of the SilverTip series for adhesive, filleting and fairing applications.
QuikFair is a lightweight, microballoon-filled, fast-curing two-part epoxy fairing putty with excellent moisture resistance. The two color-coded parts have a non-sagging, butter-like consistency and are easily mixed to form a third color.
At 77ºF QuikFair is sufficiently cured to be hand-sanded in 3 hours or machine sanded in 4 hours. This allows the user to apply three coats each 24 hours in a standard eight-hour shift or six in a round-the-clock basis.
Perfect for small fillets and cleaning up squeeze out.
1/2" or 1" Chip brushes are included to spread glues.
Included in kits requiring fiberglassing
Very important for filling cracks and holes so there are no voids in your boat
These are just right for metering out the prethickened epoxy products and mixing. They double as fillet sticks.
6- to 10-oz fiberglass cloth comes in tapes and prepackaged quantities by the yard. You will get just the right type and amount of fiberglass for your kit.
A general purpose epoxy equivalent to West System. This epoxy can be requested in place of the Silvertip products should you want to make your own epoxy using colloidal silica, wood flour, and microballoons fillers (also included).
