Gel Mediums offer many ways to build texture. Five consistencies are available from the most viscous Extra Heavy Gel to Soft Gel. Each gel is available in Gloss, Semi-Gloss and Matte finishes. They can be used to create glazes, extend paint and change finishes. Gels are essentially colorless paint, as they utilize the same 100% acrylic polymers as acrylic paint. Gels are also excellent adhesives for collage and mixed media, they dry with excellent flexibility with chemical, water and UV resistance.
