Galkyd Lite is made from a low viscosity alkyd resin and odorless mineral spirits. The viscosity is very similar to traditional painting medium based on linseed oil. It is also ready to use. Galkyd Lite is formulated to thin oil colors and maintain strong flexible paint films. Painters who prefer a lighter painting medium, landscape painters and others who enjoy painting outdoors will appreciate the longer (approximately 3 hours) working time of Galkyd Lite
