The SilverTip Series contains two putty materials: SilverTipEZ-Fillet, a wood-flour filled putty, and SilverTip QuikFair, a microballoon filled putty. Neither involve user added fillers and powders. As described elsewhere these have other advantages beyond simply eliminating the use of obnoxious, dusty powders. We suggest that most epoxy users will be better off using these rather than whipping up a batch of "homebrew" epoxy putties. Once mixed SilverTip EZ-Fillet and SilverTip QuikFair are used as described below.
Over the years nearly half of the technical service questions we’re asked involve painting and varnishing epoxy coatings. More than anything else this has been the area that has caused most people trouble. We have solved these problems by developing our own paint and clear finish system for epoxy resin surfaces - more on this later.
In the Introduction we stated that this is not a book about boat construction and repair. While that is true, we believe that the ways of using epoxy described in Section VII will have more meaning if the prospective user can relate the techniques of boat construction and repair. There are a number of boatbuilding books that go into greater depth than we will here.
Plywood is a very versatile material widely used in wood boat construction. It is dimensionally stable and needs only to be epoxy coated to protect it from moisture to become an almost ideal boatbuilding material. Several construction techniques are used to fabricate boats from plywood.
Often our technical service people take a telephone call where the question "I bought this old wooden boat and I was wondering if your product can be used to restore it?" The caller often hopes that slathering on a coat of System Three epoxy will turn the boat into a beautiful modern wooden boat. More often than not we end up dashing his hopes for a quick fix simply because there isn't one.
Many high tech one-off custom boats are built with epoxy resin and exotic fabrics such as Kevlar and Carbon Fiber laminated onto cores of vinyl foam, balsa, or thermoplastic honeycomb. Phase Two epoxy is System Three Resins’ preferred material for this type of construction. These boats are built on male or in female molds in a variety of ways.
Epoxy resins are increasingly being used to repair polyester/ fiberglass boats both above and below the waterline. The usage techniques are identical to those used in wooden boat building and described in Section VI of this book. The only real difference when using wood and epoxy is that wood is porous, at least for the first coat. Fairing and hole filling on a fiberglass hull is no different than doing the same thing on epoxy-coated wood. The same materials and tools are used.
System Three Resins’ products have been used in many areas besides boatbuilding and repair. These areas include concrete repair, radar dome fabrication, piano repair, guitar making, art deco projects, jewelry making, pottery repair, golf club repair, outdoor sign production, home and professionally built hot tubs and spas, aircraft manufacture, tooling, electrical potting, home restoration, rock polishing, and sports equipment manufacture to name a few.
Following are questions we are commonly asked when something goes wrong. We hope that you will read them because the answer to your problem may appear below. If it doesn’t then call us on our technical line and we’ll go over it with you.
The following will serve as a guide for estimating the amount of SilverTip™ Series product you’ll need. The key to any estimate is a reasonably accurate idea of the surface area involved. The numbers given are in square feet of coverage per gallon of mixed resin and hardener except as noted. Divide by 40 to convert figures to square meters per liter.
