Collection: Powertex Universal Art Medium - Textile Hardener

Powertex Universal Medium is the textile hardener I've used and taught across the USA for years, and the artists who use it say it better than I can. Read their reviews below.

Dip natural fabric into it, shape it, and it dries permanently hard, holding every fold right where you put it. It's a non-toxic, water-based medium that also works as a sculpting medium, an adhesive, and a base for mixed media on almost any porous surface except plastic.

Good to know: Shake, stir, and shake again before each use. Store at room temperature and never let it freeze. Pre-colored Universal Medium is weather-resistant once fully cured. Transparent dries clear but isn't UV resistant, so protect outdoor pieces with two coats of Easy Varnish. Mix with Stone Art or Easy 3Dflex to make your own air-dry clay.
