WEST System 410 Microlight Filler

Comments about WEST System 410 Microlight Filler:

In building my 19-foot skiff, I have used a handful of different fairing compounds, and I really didn't think much of this one. The problems with it are that even after it cures it is still kind of soft. I faired a whole 4 foot by 2 foot section of my boat, and didn't trust this stuff, so I sanding it all the way back off. I have found other fiaring compounds that mix much smoother, spread on easier, and cure much more soundly.

I have been using 410 microlight for many years mostly in my hobby work of restoring old canoes and small boats. I have found many additional uses in my workshop such as filling voids in wood working projects and in general household repairs such as filling woodpecker holes on my barn siding. West System support information is great and easy to understand.

I used Microlight filler to thicken epoxy for repairing window frames, replacing rotted wood with structurally solid epoxy.

After thickening epoxy to peanut butter consistency with 410 Microlight, I applied it with knives used with gypsum wallboard tape joint compound. By working on one surface at a time, then allowing it to set, I could re-create 90-degree convex corners (fillets) with perfect surfaces, easy to sand and then ready to paint. It sands easily, even by hand.

For this purpose, I found 410 Microlight more appropriate than the No. 406 Colloidal Silica fairing filler, because it was easier to mix, easier to sand, and produced better surfaces. If I were repairing a large overhead gap, I would fill most of it with 406 Colloidal Silica, then create the surfaces or any part requiring sanding with 410 Microlight.

I also filled gaps in stucco walls with 410 Microlight, then covered the surface with a stucco patching product. Because it is so easy to shape and to sand, the Microlight seems ideal for filling small gaps, and creating smooth surfaces, for any application that involves repairing voids of relatively small size, and for creating a surface for larger defects that are more appropriately filled with another material such as the 406 Colloidal Silica.

Incidentally, I painted all the remaining surfaces of my window frames - those with south-facing exposures (and not rotted and thus not needing replacement) - with non-thickened epoxy so they would not be later found to have rotted in the Phoenix sun.

I use this product to obtain the right consistency for inlays into turned wood objects. It does the job well resulting in as product of varying consistencies as needed. It works very well.

While I have only used the West Systems epoxy and accesories, and cannot compare it to others, it really does work well and it is easy to use. The microlight fairing filler mixes well, applies reasonably easy (even in hard to reach areas), and sands smooth with low effort.
