Jackson's Acrylic Polymer Varnish is permanent and non-removable. It cannot be removed with ammonia.
A waterborne acrylic polymer varnish which can be used straight from the bottle without dilution. This varnish dries to a protective, flexible, dust resistant surface for craft applications. Protects against UV damage.
The varnish will become milky if applied when the acrylic underneath isn't fully dry. Acrylic that is touch-dry (acrylic has formed a skin, but still isn't dry inside) may take a few weeks to fully cure, especially if it is thick. If applied to touch-dry acrylic, the acrylic underneath will take much longer to dry fully, as it has been sealed, but it should eventually become clear.
Ideal for murals and crafts. Not recommended as a picture varnish. All varnishes should be tested before use.
