This non-toxic gloss glaze is used for plastercraft or bisque after using acrylic paint. This is a non-fired glaze. Not for food or water. Brush-On Sealers produce a smooth, hard coating on your acrylic, nonfired projects. In addition to protecting your projects, sealers are used to brighten colors, too. Our nontoxic Brush-on Sealers provide the same excellent results as ceramic spray sealers and dry quickly to an invisible finish.
