Essential for use with Modern Masters Reactive Metallic Paints, it ensures superior adhesion and prevents unwanted rust or discoloration. With fast drying time, versatile surface compatibility, and efficient coverage, this primer is the must-have foundation for flawless metallic finishes. ## Description Product Description METAL EFFECTS PRIMER (Formerly Acid Block): A unique water based, acrylic primer designed to block Patina Aging Solutions and Rust Activator from reaching the metal or wood surface chosen as a substrate. Other primers cannot be used because they allow the Patina Aging Solutions and Activators to penetrate through to the substrate. This will disrupt the desired patina color and damage the finish by bringing rust or tannic acids to the surface. ~~~ FEATURES: Unique water-based acrylic prime, Blocks Patina Aging Solution from surface. For use with Modern Masters Reactive Metallic Paints. Other primers cannot be used. Covers 2. 5 sq. ft. per 4 oz. Primer Rust Red. From the Manufacturer A unique water-based, acrylic primer designed to block patina-aging solutions and activators from reaching the metal or wood surface chosen as a substrate. Other primers cannot be used because they allow the patina-aging solutions and activators to penetrate the coating. Review: Excellent results. Bought iron wine rack at flee market ... - Excellent results. Bought iron wine rack at flee market and needed TLC. Could not be happier with results. Started with blocking primer followed by MM's bronze reactive metallic and finished with green aging solution. The patina is extremely natural and the overall results exceeded my expectation. This a great set of products that actually deliver the promised results. Review: You DO need the primer with the reactive paints. - I didn't think I needed the expensive primer to go along with the reactive paints in this line, but got in anyway just in case. I'm glad I did. The bronze and the copper paints are very thin and you won't get any coverage without the primer. The primer provides a slightly toothy texture for the metal paints to grab onto, and the primer paint itself is very "grippy." I've used it on mason jar lids, glass jars, an old wooden picture frame, an ugly metal lantern, two glossy cheap plastic/resin birds, and a cheap base metal box. The primer did well on all of those surfaces. The paint goes a long way, and even though you do need two coats, two thin coats is sufficient. I've used about 1/8 of the 16 ounce bottle after all of those (albeit small-ish) projects. ## Features - include ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0050BSH9A | | Age Range Description | Adult | | Best Sellers Rank | #325,870 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #1 in Flooring Adhesive Primer #239 in Primer Paint | | Brand | Modern Masters | | Brand Name | Modern Masters | | Color | Red | | Color Code | 000000 | | Container Type | Bottle | | Coverage | 100 sq ft | | Customer Reviews | 4.6 out of 5 stars 145 Reviews | | Dry Time In Hours | 1 | | Finish Type | Metallic | | Global Trade Identification Number | 00740774998072 | | Included Components | RUST-OLEUM CORP - AM20316 | | Indoor Outdoor Usage | Indoor | | Is Waterproof | False | | Item Form | Liquid | | Item Type Name | RUST-OLEUM CORP - AM20316 | | Item Volume | 4 Fluid Ounces | | Item Weight | 1 Pounds | | Manufacturer | Paint Sundries Solutions | | Model Name | Metal Effects | | Model Number | RUST-OLEUM CORP - AM20316 | | Paint Type | Acrylic | | Part Number | RUST-OLEUM CORP - AM20316 | | Size | 16 Fl Oz (Pack of 1) | | Special Feature | Prevents Patina Aging Solutions and Rust Activator | | Special Features | Prevents Patina Aging Solutions and Rust Activator | | Specific Uses For Product | Interior/Exterior | | Surface Recommendation | Metal,Wood | | UPC | 740774998072 | | Unit Count | 16.0 Fluid Ounces | | Warranty Description | Warranty | | Water Resistance Level | Water Resistant | ## Product Details - **Brand:** Modern Masters - **Color:** Red - **Finish Type:** Metallic - **Item Volume:** 4 Fluid Ounces - **Paint Type:** Acrylic - **Size:** 16 Fl Oz (Pack of 1) - **Special Feature:** Prevents Patina Aging Solutions and Rust Activator - **Specific Uses For Product:** Interior/Exterior - **Surface Recommendation:** Metal,Wood - **Unit Count:** 16.0 Fluid Ounces ## Images ![pt Modern Masters AM203 Metal Effects Acrylic Primer - Image 1](https://m.media-amazon.com/images/I/71VUHcJ2viL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Excellent results.
