What can I do with Powertex?

This medium was originally developed as a fabric hardener for sculpture. Use it for a variety of art and craft techniques, including textured art, outdoor sculpture and mixed media crafts. It works best with natural materials.

It is a strong adhesive that works well with heavy textures, sand, wood, metal, plaster and large embellishments.

Powertex is available in a range of mixable colours, so you can create base layers to suit your project.

How do I use Powertex for outdoor art and sculpture?

Create your project with natural materials and Powertex Universal Medium and leave it to dry thoroughly. Your project will be touch dry in a around 3 hours, hardened in 3 days and cured in 3 weeks.

Cure for approximately 3 weeks for outdoor projects to be weatherproof. Powertex is a great choice for creating sculpture, garden decor including furniture or artworks for outdoors.

Add colour with pigments, paints or mica but use a varnish to protect the colour. Powertex produce their own powder pigments and Easy Varnish for this purpose.
