{"product_id":"holbein-retouching-varnish","title":"Retouching Varnish","description":"\u003cp\u003eDried paint sections lose their sheen during extended painting sessions, creating uneven gloss that makes color matching nearly impossible. Holbein Retouching Varnish solves this by restoring uniform surface reflectivity to dried areas, letting you assess color and value relationships accurately before adding fresh layers. The formulation sits between linseed oil and picture varnish in viscosity, thin enough to apply smoothly without disturbing underlying work, substantial enough to produce genuine gloss rather than a weak shine.\u003c\/p\u003e\n\u003cp\u003eThis matters most when working wet-into-dry over multiple sessions. As oil paint oxidizes, some passages go matte while others retain sheen, distorting how colors appear next to each other. A light application of retouching varnish brings everything to consistent gloss, revealing whether your color mixing actually matches or just appeared to match under uneven surface conditions. The revived sheen also improves paint adhesion for subsequent layers.\u003c\/p\u003e\n\u003cp\u003eApply sparingly to dried sections before continuing work. Once your painting reaches completion, permanent picture varnish provides final protection, retouching varnish serves the working process, not archival preservation.\u003c\/p\u003e","brand":"Holbein","offers":[{"title":"55 ml","offer_id":47979625316581,"sku":"99004","price":10.58,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0726\/6890\/5701\/files\/s99004.jpg?v=1770374714","url":"https:\/\/www.texasart.mom\/products\/holbein-retouching-varnish","provider":"Texas Art Supply","version":"1.0","type":"link"}
