Product Description

This strong, wood-toned filler is good for use in glue joints and fillets on naturally finished wood. It mixes easily with epoxy and lets you create fillets that are smooth and require little sanding. Its color is a consistent brown, so 405 can be used to modify the shade of other WEST SYSTEM fillers.

Comments about #405 Filleting Blend Filler:

For my interior relief wall panel sculptures, I find that it fits my need to use 405 with two-part epoxy and make a paste (along with a little wood dust and coloring pigment) for the shapes and forms I need. More experimentation will be done to find out the limits and to discover new textures.

    Comments about #405 Filleting Blend Filler:

    Filleting inside corners on a boat project for almost the first time though I've used West system for over thirty years in adhesive and coating ways. Having used both wood and plastic shaped filleting tools I have yet to see the "smooth" fillet requring "little sanding" in the #405 brochure. The fillets have a coarse surface that wants sanding or more filling unless covering with tape while wet and finishing that way.

    Using an orbital sander, a small rotary sanding sleeve on a small power tool, and a vibrating, tri corner sanding tool I've achieved that "smooth" surface reasonably fast. The star rating would be a four if not for the coarse surface as it's easy to mix and use within the parameters of epoxy projects.
