Powertex fabric hardener is ready to be used straight from the container. Stir well before use to ensure thorough mixing. Powertex can be applied by dipping, spraying or painting it onto your artwork. Tools and hands can be cleaned with warm water and soap. Ensure you protect your clothes and remove jewellery, as once Powertex hardens it may be impossible to remove. 100% Natural fibres work best. Test a sample before starting your main work and if the fabric sticks to itself, it should work well. Natural fibres will cure harder than unnatural fibres. Powertex is absolutely safe for humans and animals and meets the highest European and American safety standards. Powertex has undergone extensive testing and has been awarded the AP Seal. NB. Powertex is not frost free while liquid. Don’t store or transport below 0°C. The minimum working temperature for Powertex is 10°C. After Powertex is cured, the temperature does not affect the finished product.
