1 Quart 100% Pure Fumed Silica Powder, Advanced Thickener for Epoxy, Paints, Varnishes, Professional Fumed Silica for Filling Cracks and Voids, Worked Well for Ceramic Blanket Rigidizer - by TITGGI

I do resin art, sometimes I get it too runny so I put a little this magic stuff and poof I can it helps me correct a lot of mistakes I would recommend it to anyone who deals with any type of product were consistency is important and sometimes when it gets too runny this helps and if I understand correctly it is food grade, but it did an outstanding job for me big thumbs up

Works great

I cant always get really flat paint for small touch-up latex samples. Matt samples are not perfectly flat paint and shine on pre-painted surfaces. The silica powder kills any sheen and makes the latex samples thicker for drip free applications on ceilings or walls. I mix the silica and latex in small tins and let sit for a minute or two before applying. I little goes a long way, use fractional teaspoons per ounce of paint.

This worked but was kind of clumpy. Rustolium metallic gold paint is very runny and hard to work with. This did make it less so.
