Marine Tex Epoxy Putties & Putty
Marine Tex Epoxy Putty: The Legendary Structural Repair Compound
When it comes to epoxy putties and repair putty, few names carry as much weight on the water as Marine Tex. With more than 40 years of proven performance, Marine Tex has earned its reputation as the go-to structural epoxy for boat owners, marine mechanics, and industrial repair professionals who need a solution that holds up under the harshest conditions.
What Makes Marine Tex Epoxy Putty Different
Marine Tex Epoxy Putty is a heavy-duty structural epoxy — not a cosmetic filler. It is engineered for filling, bonding, and rebuilding wood, fiberglass, ceramic, glass, metal, masonry, and many plastics, making it one of the most versatile repair compounds in the marine world. What truly sets it apart is its ability to make repaired areas stronger than the original material.
The formula mixes to a thick, creamy, no-sag consistency that can be applied to both vertical and horizontal surfaces without slumping or running. Once cured, it can be sanded, drilled, tapped, sawed, and finished with most common paints and coatings — giving you a repair that is essentially indistinguishable from the surrounding substrate and fully workable like any structural material.
Key Features of Marine Tex Epoxy Putties
- Waterproof and chemical resistant: Impervious to oil, grease, brine, fuel, and detergents — ideal for below-waterline repairs and fuel or water tank sealing.
- Two color formulas: Marine Tex Gray is the go-to for machinery and mechanical repairs; Marine Tex White is preferred for fiberglass and wood applications and can be tinted with compatible coloring agents.
- Multiple kit sizes: Available in convenient 2 oz., 14 oz., quart, and gallon kits to match the scale of any repair job.
- Simple 5:1 mix ratio: Proportioned by volume — 5 parts epoxy resin to 1 part catalyst/hardener — for straightforward, reliable mixing every time.
- Broad substrate compatibility: Bonds dissimilar metals without galvanic corrosion, repairs aluminum, fiberglass, and wooden boats, and reinstalls loose or stripped fasteners.
- Approximately 30-minute working time: At 72°F, you have ample time to shape and position the putty before it begins to set, with a full cure in 24 hours.
Common Applications
Marine Tex Epoxy Putty handles a remarkably wide range of repair scenarios. It is an excellent choice for emergency and permanent repairs to hulls, decks, exhaust lines, outdrives, piping, stringers, and engine blocks. It seals leaks in fuel tanks and water tanks, bridges holes when used with fiberglass tape or cloth, and can even secure hardware and stripped fasteners by casting threads directly into the cured epoxy. Its resistance to water and chemicals also makes it a reliable option for problem areas located below the waterline.
Whether you are a first-time DIYer patching a hull gouge or a seasoned marine mechanic keeping a vessel in service dockside, Marine Tex Epoxy Putty provides the structural integrity and workability that demanding repairs require.
