Comments about WEST System WEST System Notched Spreaders:
My application was laminating three layers of MDF sheet goods for a bench top. I wanted to distribute a thin even layer of Tite-Bond III as fast as possible over a large surface before it began to set up. The first pilot attempt failed because with an unrelieved sawtooth profile, 1. the glue does not spread well and 2. most importantly the layer of glue even once spread will be 1/2 the depth of the tooth. This was too much glue even for the shortest teeth. I solved this by cutting off the tops of the medium height teeth using a straight bit on the router table. The glue spread much more evenly organized into ridges that collapsed into a very even and thin layer when the sheets were pressed together.

It sounds funny to call a plastic spreader a professional tool. But it is. The pros use serrated or notched spreaders just like these. The use them for a reason. Better control and distribution of epoxy, putty, fillers, etc. Try the right tool and be surprised at the good results.
