Liquitex Spray Varnish uses water-based technology, has a low odour and is permanent and durable. It can be used alongside spray paint to protect acrylic colour from harsh elements. Once dry it is a water-resistant, non-tacky, hard, flexible surface which is resistant to dirt retention. The varnish resists discolouring due to humidity, heat or ultraviolet light. Translucent when wet, transparent when dry. For interior and exterior use. UK shipping by road only. Not available for Northern Ireland and International shipping.
