PRODUCT DESCRIPTION:
Metal Effects Acid Blocking Primer (AM203) is a unique water-based acrylic primer. Unlike other primers, it is especially formulated to block Metal Effects Patina Aging Solutions and Activators from reaching the metal, wood, or reactive substrate. This helps prevent the formation of rust or other oxidation products, and helps block tannic acids (contained in wood) from rising to the finished surface.

SURFACE PREPARATION:
Before applying Metal Effects Metallic Paints, the previously coated surface must be completely clean, dry, and fully cured. Remove all loose, peeling paint. Patch and repair any surface imperfections before using the Metal Effects Acid Blocking Primer. All surfaces should be sound, clean, free of oil, grease, wax, and other contaminants, and completely dry prior to priming. Surfaces previously primed require light sanding. Scuff sand any glossy surfaces. Stir well before and occasionally during application. Do not thin the Acid-Blocking Primer. Apply the Acid-Blocking Primer as the last step in surface preparation before the application of the Metal Effects Metallic paints. Some metal surfaces, such as bare aluminum, galvanized iron, or rough metals, will need a metal primer or an anti-corrosive primer applied before the application of Metal Effects Acid Blocking Primer. Clean and prime the metal per the metal primer label instructions.

Important Note: DO NOT use Metal Effects Acid Blocking Primer under the Metal Effects Baroque Metallic Paint.

The Metal Effects Acid Blocking Primer is especially formulated to block out alkali salts, tannins, acid salts, or other unwanted contaminates from ‘bleeding through’ to the Metal Effects Metallic Paint film and causing adverse reactions and unwanted color changes with the metallic particles in the Metal Effects Metallic Paints. If unsure of the substrate, test a sample area to ensure the desired results. Apply at least two coats of Metal Effects Acid Blocking Primer to completely seal and block the surface. When painting over bare metal, a metal primer probably will be needed as a first coat.

APPLICATION:
Modern Masters Metal Effects Acid Blocking Acrylic Primer can be brush, roll, or spray applied. Use brushes and rollers appropriate for water-based primers. Use an HVLP spray gun powered by an air compressor or quality airless sprayer for spraying.
Important Note: Do not use a turbine “air compressor” to power the HVLP spray gun. When spraying, use a properly fitting, NIOSH approved breathing air mask fitted with an organic vapor cartridge.
Note: Do not mix this primer paint with any other paint, extender, or additive.

Coverage:One gallon/3.78 liters will cover approximately 300 sq. feet/28.8 sq. meters.

Film Properties:

Drying time at 70°F and 50%RH: Re-coat time is in approximately ½ hour; dry time is in approximately one hour; full cure is in approximately 24 hours. Lower temperature and higher humidity will lengthen the dry and cure times.

Clean Up: Clean brushes, rollers, tools, and equipment with warm, soapy water immediately after use.
