## Description

Product Description Modern Masters AM203-04 Acid Blocking Primer White, 4-Ounce 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: AMAZING RESULTS! - I purchased this to create an antiqued copper look to an existing white drop ceiling grid in a bathroom we were remodeling. I had purchased Faux Tin Ceiling Tiles with a Weathered Copper look (Drop In) and really wanted to not have to replace the grid. All I can say is - WOW!!! The photo's speak for themselves. A little goes a long way. This was done with one bottle each of the Modern Masters ME-149 Reactive Metallic Paint Copper, Modern Masters PA901-04 Aging Solution Green Patina and Modern Masters AM203-04 Metal Effects Primer. Outstanding product!
Review: This is the primer - it doesn't change color - I used this primer under the bronze effect topcoat to paint a garden trellis. It looks great! (Photo added of the base of the trellis) I can only assume that the people giving this one star and saying it "does nothing" are confused about what this particular product is. This is the primer that goes under the color-changing (oxidizing) paint. The primer does not change color (oxidize). That is the point of the primer – to block the oxidation from the topcoat getting to the substrate underneath.

## Questions & Answers

**Q: Would this primer work on plastic, or should I just use a regular plastic primer?**
A: May not stick on plastic.

**Q: I'm doing my 1890s small molded iron fireplace hood and frame. I was wondering if this primer would withstand a little thermal heat on the metal? Otherwise, I'm thinking I should prime with an automotive engine or ultra high heat metal paint instead.**
A: I think that this is decorative, so your plan of high heat paint is better.  I would worry that this will burst into flames

**Q: Is primer needed on fiberglass?**
A: Use a bonding primer like XIM UMA. The primer included is to block acids.

**Q: Can I use this on concrete statues and do I still have to prime it?**
A: Yes you can. I've done concrete lions with it and they look great. As far as priming...I've wondered the same thing but chose to go ahead and prime because of the cost of the paint. Seems like a small expense compared to the paint to risk a malfunction.

### ⭐⭐⭐⭐⭐ Works for me!
*by C***N on October 28, 2013*

I cannot comment on durability as this was my first project using this primer and coordinating paint, and it is still fresh. The label recommends two coats of this primer, which is what I did and the Metal Pint went on beautifully. Also I think maybe the color of the primer adds depth to the color of the metal paint, although I can't say for sure because I have not yet tried a project without the primer. The five star rating is due to the fact that the metal paint easily covered the item with even color and lots of depth, which gives a very realistic appearance, and think that is at least in part due to the primer.
