Reasonable price, easy to use
Very effective...stirs in well with the epoxy, has no odor, and doesn't seem to affect the curing time, or noticeably add to the volume.

Works as advertised
Although I did not use this as a covering, I did use it to glue 32 ga steel to a structure with both a positive and negative curve. Held in place with a sandbag, it seems to have worked quite well. Of course it’s always difficult to give initial quality on something when that quality will only become apparent after at least a year.

It make a different
I used this for the first time, I followed the instructions and It work as it say, Without it I don't think I will be able to complete the job using the epoxy the same as if I covering a wall with cement .

Ok. Lightens your epoxy color.
Works alright; my only real problem is that it changes the color of your epoxy. It's like mixing in white with whatever color you actually wanted.

Really thickens well
This stuff really thickens epoxy a lot. You can go overboard quickly, as I found out. It's so lightweight, it feels like you aren't adding much -- then bam, you suddenly have peanut butter. Which might be just what you need! Best to add a little at a time, mix well, and note how much you added to a set amount of epoxy in order to get your desired viscosity. Great filler, all around. Does make clear epoxy turn milky in higher concentrations.

Works perfect
It worked better than expected. The only issue I had is it tinted the epoxy a dull white color but that was easy to work around. The project i was working on was a bathtub and i needed something to seal my edges du to stupid sheetrock work. So this worked for me with some minor tweeks.

That the epoxy doesn’t look milky
I’ve not worked with an epoxy thickener before. It maybe more suited for colored epoxy
