Permalac NT Blackener is our low VOC NT formula Permalac Lacquer with a transparent black tint added. This allows you to seal and blacken your metal in one step, no patina chemicals required. Use it to easily and quickly create a blackened steel or anodized look. 1 quart will cover 100 square feet with a single coat.
Use Permalac NT Blackener just as you would Permalac. The substrate should be clean and dry before application. Wipe the surface clean with a acetone. For best results, a spray application is recommended. A minimum of three total coats is recommended. Thin the first coat 1:1 with lacquer thinner such as #770. No thinner is required for the subsequent coats. Apply thin coats for an even finish. Allow 15 minutes between coats. Each additional coat will increase the blackening effect. If a lighter finish is desired you may wish to get some clear Permalac NT to use as a top coat. Use lacquer thinner or acetone to clean equipment. On days with high relative dew points, a 2-5% addition of #500 is recommended for all coats.
