PowertexTransparent-Textile Hardener-500g, Other Material, Multicolor, 500g, Set Pieces

This product is perfect for my projects. It stiffens the material without flaking or yellowing. My pieces were stiff without yellowing or flaking or changing the color of my material/cloth. I had to scrunch my pieces before hardening but with the consistency of glue it molded quickly. I used brushed and fingers and was able to get good coverage. I am so glad found this product. A little goes a long way. .

Came very quickly. I love this stuff - you can harden almost any organic material and the results are able to be kept outside

Dried clear

I tried this on leather and on fabric. It is smooth and easy to apply. Once dry it did make the materials stiffer, but there was still quite a bit of flexibility and movement. A second coat did not improve the situation very much. If you bend it, it does crack a little, but doesn’t peel or chip off. When I used it on the fabric, it did turn the fabric a bit darker, mostly because the fabric absorbed the liquid.I was hoping for it to make the materials very stiff, almost hard, so it did not work for my purposes, even with a second coat. Now, it would appear I am stuck with a large bottle of expensive stiffener that I have no use for as I would guess I can’t return an open container (although I have not checked the return policy yet).

grate!

I tried this product for a halloween project, and the hardener took a long time to dry, and the fabric I used (cotton) did not give me the stiffness I needed. I really cannot recommend this product.My solution was to use a resin based activated liquid to soak the fabric with a working time of 9 minutes. it was a little mess

Works very much like any other fabric hardener, but MUCH more expensive. Not rock hard as you would expect from the product description.
