Seal your acrylic work with a transparent, gloss acrylic layer which is permanent and protects against UV damage. Dries clear to a flexible, non-tacky, hard surface. Resists discoloration caused by humidity, heat and UV rays. Excellent leveling properties - will not hold brush marks. Semi-opaque when wet, transparent when dry. Depending on the substrate, it allows surface moisture to pass through and breathe. Before varnishing, ensure paint surface is fully dry. Apply up to three thin coats, allowing at least three hours dry time between coats. 4 oz. bottle. AP Seal, non-toxic.
