West System Painting Supplies Editorial Review

The West System 206-A Slow Hardener is highly recommended for wetting and laying up fiberglass cloth with West System 105 epoxy resin. It has a 20-25 minute pot life at 72degF and requires 12-18 hours for solid cure. The hardener can be mixed in a 5:1 ratio with resin. However, it is not compatible with Rustoleum epoxy or paint. Users have successfully applied a layer of polyurethane finish on top of wood inlays created with this hardener without any adhesion issues. The hardener has a tint but cures clear. Overall, this product is well-regarded for its quality and performance. Please note that the product photo on some listings may be incorrect as it shows a smaller can size.
