Wood Rot Repair Kit by West System

The new Wood Rot Repair Kit from West System provides a cost-effective and time-saving solution for making structurally sound repairs to rotted wood. This two-part, solvent-free epoxy system penetrates deep into damaged areas and restores structural integrity by consolidating weakened wood fibers. It is formulated to be flexible enough to move with the wood’s natural movement, preventing issues from cracking.

Whether restoring a boat, garden house, home project, or addressing delamination on a campervan, this wood rot repair epoxy makes damaged wood structurally sound for years to come.

Versatile and long-lasting product
Compatible with fillers: When mixed with West System fillers, it creates a thickened epoxy perfect for filling large voids or rebuilding missing sections of wood.
Prevents cracking: Designed to maintain slight flexibility, the epoxy accommodates natural wood movement without cracking.
100% solid formulation: Being solvent-free, it is not susceptible to the shrinkage or unwanted voids often caused by traditional penetrating epoxies that contain solvents.

Directions for Use

Surface Prep

Remove paint/varnish and rot/debris
Dry the wood out (ideally reach less than 12% moisture content)
If deeply rotted, consider drilling holes into the rotted areas to allow for deeper penetration

Application tips

Brush or spread liberally on the surface
Allow epoxy to soak in. Reapply if needed.
Do not apply thicker than 12mm per application. At a 22°C shop temp, you can apply additional 12mm layers every 3 hours.

Finishing tips

Once fully cured, you can paint, varnish, or poly over the top. Be sure to remove any amine blush before doing so. For best results, sand and clean the surface beforehand. Note: For marine applications, we recommend glassing with 105 Epoxy Resin over the repair area.

Adding Fillers

WEST SYSTEM Fillers can be used to thicken the epoxy for better gap filling, or for filling voids on vertical surfaces. For most repairs made with Wood Rot Repair, 407 Low-Density Fairing Filler and 405 Filleting Blend Adhesive Filler yield great results.
