Liquitex Spray Varnish uses water-based technology, has a low odour & is permanent & 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 & exterior use. UK shipping by road only. Not available for Northern Ireland & International shipping.
