Anyone that has tried to wrap a bottle or glass with Powertex will know that it can be a slippery business! It’s not difficult to achieve though. With a couple of tips you’ll be making potion bottles, turning wine glasses into beautiful goblets and redesigning your mirrors!

Does Powertex stick to glass?

Yes and no! Powertex works well with a glass surface, it will adhere. However, glass is also a smooth, slippery surface so giving it a little help can be a good idea.

Preparing the surface

Tip 1

Clean off any dust, dirt or oil and start with a dry surface. 

Tip 2

If you’re decorating bottles, leave any labels on. This gives a little texture for your Powertex and fabric wrapping to cling to. These are usually hidden at the end.

Tip 3

Use small pieces of masking tape on smooth surfaces to create areas with texture.

Masking tape is your friend. It can be used in small pieces on the shoulders of bottles or the stems of goblets where it will be hidden. It will also completely cover mirror edges if you want to create a frame.

Tip 4

Wipe away excess Powertex medium before it fully hardens. It will clean off glass easily for several hours but not when fully cured.

Tip 5

When dry brushing Powertex textures, use cling film to protect “clean” areas from varnish and colour. It’s too easy to flick the Easy varnish all over the clean glass and it’s time consuming to remove afterwards.

Looking after your glass creations

Powertex is water resistant after 3 weeks. Goblets and bottles can be hand washed and rinsed but should not be submerged in water or put in the dishwasher.

Projects can be rinsed under a tap to clean. Hot water will soften the Powertex it will harden again when it cools.
