This formula maintains the fluid handling properties that make acrylic painting efficient while intensifying color saturation and creating reflective surface shine.\u003c\/p\u003e\n\u003cp\u003eCrystal-clear formulation dries without yellowing or clouding, preserving color accuracy beneath its protective layer. The medium increases paint flow without compromising opacity control, you get easier brushwork and extended open time for blending while maintaining the ability to build from transparent glazes to solid coverage. Applied as varnish, it seals completed paintings against dust and minor surface damage while unifying sheen across mixed-media layers.\u003c\/p\u003e\n\u003cp\u003eGrumbacher formulates this medium to remain flexible after curing, moving with canvas expansion and contraction rather than developing stress cracks. Brush it on in thin, even coats for varnishing, or add progressively to paint until you achieve desired flow characteristics. Works particularly well for creating luminous glazes over dry underlayers and for artists who prefer high-gloss finish to matte or satin alternatives.\u003c\/p\u003e","brand":"Grumbacher","offers":[{"title":"8 oz. jar","offer_id":48102313361637,"sku":"23276","price":25.17,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0726\/6890\/5701\/files\/s23276.jpg?v=1768580770","url":"https:\/\/www.texasart.mom\/products\/grumbacher-acrylic-gloss-medium-and-varnish","provider":"Texas Art Supply","version":"1.0","type":"link"}
