<h3>About WEST SYSTEM Epoxy</h3><p>Since 1969, <strong>WEST SYSTEM</strong> has been the benchmark for marine-grade epoxy technology. Founded and headquartered in Bay City, Michigan, the brand built its reputation in the demanding world of boat building and boat repair — environments where structural integrity and long-term moisture resistance are non-negotiable. Decades later, WEST SYSTEM remains the go-to choice for professional boatbuilders, marine repair technicians, and dedicated DIYers around the world.</p><p>At the heart of the brand is the legendary <strong>105 System</strong> — a modular, field-proven approach to epoxy that gives users precise control over every aspect of a repair or build. The system centers on WEST SYSTEM Epoxy Products, which pair the 105 Epoxy Resin with a selection of hardeners, each engineered for different working conditions and cure speeds. Whether you need a fast-setting compound for a quick on-the-water fix or a slow-curing formulation for a complex laminating job in warm weather, there is a hardener designed for the task.</p><p><a href="/7644-west-systems-epoxy-adhesives-200378">WEST SYSTEM Epoxy Adhesives</a> take that same foundation and extend it into high-strength structural bonding. These formulations are compatible with wood, fiberglass, Kevlar, carbon fiber, metals, and ceramics — making them equally at home in a marine boatyard, a woodworking shop, or a composite fabrication facility. WEST SYSTEM epoxy forms strong, load-bearing bonds that often exceed the strength of the surrounding material , which is why builders trust it for everything from hull construction to bulkhead installation.</p><p>Rounding out the system, <a href="/200404-fillers-west-systems-7644">WEST SYSTEM Fillers</a> allow users to fine-tune the physical characteristics of a mixed epoxy batch. Users can adjust the epoxy with one of six WEST SYSTEM fillers, or add one of several additives to create specific coating properties. Options range from low-density fairing compounds ideal for creating smooth, sandable surfaces, to high-density microfiber blends engineered for structural glue joints and filleting work.</p><h3>Why WEST SYSTEM Stands Apart</h3><ul style="list-style:disc"><li><strong>Modular versatility:</strong> WEST SYSTEM Epoxy products make up a versatile epoxy system that can be used for everything from basic, long-lasting, marine epoxy repairs to the construction of high-performance composites. </li><li><strong>Moisture resistance:</strong> Designed to create a protective barrier, WEST SYSTEM epoxy prevents water infiltration, ensuring long-term durability in marine environments. </li><li><strong>Broad material compatibility:</strong> WEST SYSTEM marine epoxy is compatible with various materials, including fiberglass, Kevlar, and carbon fiber, for superior structural integrity. </li><li><strong>User-focused design:</strong> WEST SYSTEM 105 Epoxy Resin, Hardeners, Fillers, Additives, and Materials are designed and developed with the end-user in mind. </li></ul><p>Whether you are restoring a classic wooden sailboat, cold-molding a new hull, patching a delaminating deck, or fabricating a custom composite component, WEST SYSTEM provides the engineered materials and the technical guidance to get the job done right the first time.</p>

Product Details

West Systems 690-1.5G Wood Rot Repair Kit is a 1.5-gallon two-part epoxy system engineered to penetrate, stabilize, and rebuild rotted wood without requiring full replacement. Suitable for home, marine, RV, and general stabilization applications, this kit delivers professional-grade structural restoration in a convenient all-in-one package.

The system works in two stages: a deep-penetrating epoxy first saturates and hardens degraded wood fibers, restoring structural integrity from within, followed by a rebuilding compound that fills and replaces missing or severely damaged material. The result is a long-lasting, structural repair that can be sanded, shaped, and painted.

Key Features:

  • Two-part epoxy formula penetrates deep into rotted wood fibers to restore strength
  • 1.5-gallon kit size — ideal for medium to large repair projects
  • Suitable for interior and exterior use
  • For use in home, marine, RV, and stabilization applications
  • Repairs can be sanded, shaped, and finished to match surrounding surfaces
  • Made in the USA
  • From WEST SYSTEM — a trusted name in professional epoxy technology

The West Systems 690-1.5G is the large-volume option for contractors and serious DIYers tackling significant rot damage on decks, window frames, door sills, transoms, marine woodwork, and structural members.
