{"product_id":"spectrafix-instagrit","title":"InstaGrit","description":"\u003cp\u003eLayering wax-based media eventually creates a surface so smooth that nothing else sticks. InstaGrit reverses that, brushing on an invisible tooth that grabs pigment immediately without adding texture you can feel or see. The solution dries completely transparent and flat, letting you continue building color exactly where heavy application has sealed the paper surface.\u003c\/p\u003e\n\u003cp\u003eThis brush-on medium restores receptivity for colored pencils, graphite, pastels, and charcoal when burnishing or repeated layers have made further work impossible. Unlike traditional grit preparations that add visible texture, InstaGrit maintains your existing surface character while creating microscopic tooth that catches pigment. Graphite pencils achieve significantly richer blacks over treated areas, depth that pressure alone can't produce. The medium also accepts watercolor tinting, letting you establish a toned ground with built-in tooth for subsequent drawing.\u003c\/p\u003e\n\u003cp\u003eApply InstaGrit selectively for corrections and detailed additions, or coat entire panels and papers before starting to create a consistently receptive surface. The transparent finish disappears under subsequent layers, making it particularly valuable for photorealistic work where surface uniformity matters. Works across colored pencil, soft and oil pastels, charcoal, and graphite without changing how your familiar media behave, just how readily the surface accepts them.\u003c\/p\u003e","brand":"SpectraFix","offers":[{"title":"2 oz. \/ jar","offer_id":48082698043621,"sku":"47766","price":11.96,"currency_code":"USD","in_stock":true}],"url":"https:\/\/www.texasart.mom\/products\/spectrafix-instagrit","provider":"Texas Art Supply","version":"1.0","type":"link"}
