Create faux stone effect with Powertex by Kore Sage

Powertex Stone art is a product for creating fine textures, faux stone effect and of course air drying clay. Use with Powertex Universal Medium for convincing stone results.

Stone effect Powertex Stone Art

Hi it’s Kore! So this month is all about Stone Art at Powertex HQ. It’s the perfect opportunity to show you a favourite technique of mine. I’m demonstrating how to create a faux stone effect on almost any surface. In this demonstration I’ll be using a piece of styrofoam. Watch the video for my demonstration and pop the sound on. I’ve listed my supplies below.

Step 1

Applying Powertex

Put a little Powertex medium onto your plate and use your fingers to apply it unevenly to the surface, not too thin. Wear a glove for this if you like.

Step 2

Applying Stone Art

Use a dry hand to sprinkle Stone Art powder onto the wet Powertex. Cover it completely and be generous. Don’t worry we won’t waste any! Press the Stone Art onto the wet Powertex firmly. Use your fingers to brush off any excess powder into your spare container. Repeat this process as many times as you like to create your textures. You can apply it more in some areas. I recommend leaving to dry for a while before moving to the next step. You can use a hairdryer to speed this up if you wish.

Step 3

Buffing your textures

When you have your dry layers of Stone Art we want to remove any loose powder. Use your fingers flat over the textures, rubbing firmly to remove any Stone Art that’s not stuck down. Any loose powder can be saved into your container and used again. It will be more textured than the “new” Stone Art. Buff over the whole piece until your happy. You should be able to see your textures well now.

Step 4

Using Bister sprays

Adding Bister spray to Stone Art textures

To make the most of the textures, spray Bister generously onto the piece. You can use any colours, layer them up and mix them together. Dry them off in between if you like. I find the more the better here.

Next use a damp sponge to wipe the Bister from the raised areas. This creates highlights. Repeat these steps until you get a result you like. The Bister is water based and not permanent so you can wipe this back and repeat as much as you like.

You can use this technique on most surfaces including glass, canvas and wood. If you have a plastic surface, the Powertex will likely peel off. It’s a good idea to prime the surface first with masking tape, gesso or a spray primer.

As Bister is not permanent you may wish to seal your project with varnish. You can use Easy Varnish but a spray varnish will also work well.  These pieces make great bases for animal sculptures! Note that Stone Art is made of paper and varnish is also highly flammable so is not suitable for use with real candles.

I hope you’ve learnt something you can use.  There are other Stone Art projects on the blog if you feel inspired. If you have a question about this technique, leave me a comment and I’ll do my best to help.

You can find more of my projects over at Kore Sage Art.

Until next time, let your art out!
