Tri-Art Top Coat Hard provides artists with a very hard, scratch resistant finish that is intended for use on rigid surfaces, and not recommended for flexible, pre-gessoed surfaces or substrates (use on low quality canvas & substrates could cause uneven shrinkage, warping or even snapping of stretcher bars). This archival water-based product dries to a high gloss, transparent and non-tacky finish. It is washable and non-yellowing. Top Coat pours easily, is completely self-leveling and can be thinned with water. Top Coat can also be sprayed from an airbrush to produce a thin, hard finish. Once dry, it will remain semi-flexible even in multiple layers and will not crack in thick applications. To achieve a more matte finish, mix with Matte Polymer Medium. This is the ideal medium for sealing floor cloths painted with acrylics.
