Great filler from west system A++++++

This stuff works great!! It’s not easy to mix into the epoxy, it’s so insanely light, it just floats away if you’re not very very careful!! Add a little at a time, mix inside a garage or somewhere the wind can’t get to the mixing bowl. Once it’s mixed in, it does a great job thickening up the epoxy. Great for vertical surfaces as it really holds upright well once mixed to the proper thickness.

I used this to thicken the epoxy so it wouldn't run down through large cracks and nail holes in a rustic oak floor. Unthickened, the epoxy would disappear as quickly as I could inject it. This is a great system. It's very easy to mix this in until you get the desired thickness. I spread it on with a stick, smashing it down into the holes.

The West System Silica additive worked great for filling the small gap that I had after installing the wood floor in my boat. It exceeded my expectations.
