Painting with Powertex

I love painting with Powertex Universal Medium (Powertex) and I wrote about making Powertex mixed media art in this blog.

Start out with a bottle of Ivory Powertex Universal Medium, a tub of Stone Art and a few pigment powders and apply them directly to the wet Powertex. My first experiment with Powertex on canvas is shallow textures and muted colours. I really love the colour blends and light textures from the stone art but there’s a lot more to experiment with.

With these shallow textures I was beginning to see how the materials worked and what could be possible. The process of playing with the products cannot be underestimated.

Why use Powertex medium?

I use texture and other media in my painting as Powertex has some unique properties. Here’s a reminder:

  • Powertex Universal Medium is a fabric hardener, adhesive and paint for sculpture and textured art.
  • It’s water based, non toxic and environmentally friendly so that ticks another box for me.
  • The adhesive quality of Powertex is strong enough to support almost anything from heavy collage fabric and plaster to wood and metal layers. Use with natural fibres.
  • Powertex has a slow drying time which allows lots of time to experiment.The open time is about 1 hour.
  • It’s hardwearing and weatherproof for creating outdoor sculpture or art.

Here are some examples of textured art I have created using Powertex products.

Add colour

Blend different colours of Powertex medium directly on canvas, board or heavy card. Add colour with Powertex Bister ink sprays and powdered pigments such as Powertex Powercolor. Your acrylic inks, paint and sprays are also compatible although these don’t usually mix well into Powertex. Oil based products are not compatible with Powertex Universal Medium. 

Add texture

With the exception of plastic, almost anything can be used as texture with Powertex. Layer fibres, papers, textiles, cork, leather and wood or Powertex texture mediums.

The range of Powertex texture products such as Stone Art, Rusty Powder, 3d Sand and Easy Structure are developed to be compatible with Powertex. Try Easy 3d Flex and Powerwax for advanced techniques.

Powertex Stone Art is a dry paper powder that can be adhered to a surface and sculpted when mixed with Powertex.

Rusty Powder is an iron based powder that rusts when combined with vinegar. The strong adhesive Properties of Powertex allow the rust to be adhered to many surfaces.

3d Sand is a fine absorbent sand developed to mix into a liquid adhesive to add texture.

Easy Structure is a heavy texture paste that can hold high textures and is hard wearing when dry.

Mixed Media Powertex art techniques to try

  • Create a textured surface with Easy Structure paste with shaped tools or a stencil and paint with Powertex when dry.
  • Use two different colours of Powertex and mix them into each other on your surface.
  • Adhere torn pieces of corrugated card, heavy handmade papers or fabric to add texture.
  • Add 3d sand to Rusty Powder mixtures for authentic rust textures.
  • Press Stone Art into wet Powertex for a softer surface and build up layers for a “stone” effect.
  • Alternate texture and colour layers for lots of detail.
  • Use Powertex and fabric to sculpt on a flat surface.
  • If you love crackle, invest in some Easy 3d Flex to mix with your Powertex and blend colour into the textures with Powerwax.
