Jolie Extender is a translucent liquid that mixes with Jolie Paint to increase open time and create custom glazes. It's ideal for finishes where Jolie Varnish is the desired topcoat, as it will allow you to layer colors and add depth to your painted finishes without the use of colored waxes, which can't be used under Varnish.
Jolie Extender can also be added to Jolie Paint and Varnish in smaller amounts to increase flow and level, minimizing brush and roller marks and making it easier to achieve an ultra-smooth finish.
