 1. Does BronzeShield™ replace wax?
BronzeShield™
 lasts at least ten times longer than wax and is also easily removable. It is much easier to apply and remove on textured surfaces and does not wash or melt away in water installations or under heat. It protects better against UV and saltwater and unlike wax, is extremely resistant to solvents and cleaners. BronzeShield™ also saturates corroded metal much like wax does, although many conservators like to use a sacrificial layer of wax on top of BronzeShield™ to further protect the surface and to adjust the sheen and color for each project.

 2. Do I need to clean my sculpture before coating it with BronzeShield
Surface preparation is key to the success and durability of any coating
. BronzeShield protects a polished, patinated or weathered (corroded) surface as long as it is dirt, wax and oil free. Proper cleaning and/or professional restoration may be needed before applying BronzeShield.  In many cases, cleaning with soap and water or a powerwasher is sufficient.

 3. Can this product be used on new and old sculptures?
Yes, it works on clean polished, patinated and weathered bronze, although the amount of material needed will vary based on saturation rates.

 4. Can BronzeShield
 be used to saturate a corroded surface? 
Yes. A thin layer can be used over weathered bronze to protect the surface from further deterioration. Unlike other clearcoats, BronzeShield
will saturate and possibly darken the surface much like wax.

 5. Can I alter the glossiness?
BronzeShield™ is now adjustable, according to your needs! By adding the minimum ratio of hardener, you can obtain a gorgeous matte finish that looks much like wax. By increasing the amount of hardener in your mixing step, you can increase glossiness to your preference. You can also still wax over the cured coating if you want to achieve a more matte appearance, according to your preferences.

 6. Can BronzeShield™ protect against vandalism and grafitti? 
Yes. BronzeShield™ does not allow paint, markers, etc. to penetrate through to the surface and ruin the patina and possibly the metal itself. BronzeShield™ can withstand cleaning solvents to remove graffiti or simply use a suitable non-toxic remover to take away all layers of graffitti and protective coating down to the patina. Clean and recoat. 

 7. How is it applied?
BronzeShield™ can be sprayed or brushed on. It is a cross-linking two-component new generation polyester-urethane system that requires mixing before using. We recommend spraying.

 8. How do I remove BronzeShield™ when it's time to clean and recoat?
You do NOT need to use harsh mechanical methods or toxic solvents (xylene, toluene) to remove BronzeShield™. Apply Elinor’s BronzeShield™ Remover or a commercially available suitable safe, non-toxic paste remover, and rinse clean with water. The remover does not harm the bronze, the patina or the environment and will leave your surface coating free.

 9. Can I use commercially available removers on BronzeShield™?
Yes, there are readily available non-toxic removers on the market that will safely remove BronzeShield™. However, not all of them have optimal properties for use on vertical and hard to reach surfaces. A paste consistency is optimal for both speedy removal and excellent adhesion.

 10. How does BronzeShield™ compare to other polyurethanes  or lacquers like Incralac or Permalac?
BronzeShield™ performs as well or better than a high-performance traditional polyurethane and outperforms one component lacquers, such as Incralac and Permalac in outdoor weathering. But, unlike both lacquers and traditional polyurethanes, BronzeShield™ is easily reversible on demand, due to a patent-pending polymer design which allows cross-linked bonds to break when a link embedded in the polymer chain that is protected when exposed to weathering, acids and pollutants, is activated by the remover. BronzeShield is also wonderfully easy to mix and alter the surface sheen without adding matting agents, thinners or other additives on the jobsite.

 11. Is BronzeShield™ environmentally “green?” Can I use it in California?
BronzeShield™ is solvent-based, yet complies with ultra-low VOC requirements of the strictest environmental standards in California, making it acceptable for indoor and outdoor use anywhere in the USA. It contains no carcinogens or environmentally-toxic materials. It can be disposed of using standard responsible disposal methods. Removal of BronzeShield with the zero-VOC remover creates no toxic waste or health hazard. It does contain t-butyl acetate in the hardener, which is stinky stuff, so especially if using indoors, you will need adequate ventilation and respirator protection. 

 12. Why coat bronze? Isn't it supposed to weather naturally? 
The patina the artist intended, whether it is a traditional or modern finish, is impossible to maintain when left exposed to the elements in outdoor conditions. Bronze is made of copper and tin, and those metals begin to oxidize immediately when exposed to air and moisture, especially the pollution of modern society after the industrial revolution. Weathering "naturally" eventually results in a very unnatural and damaged surface.

 13. Will this coating work on other materials?
Yes, it also works on brass, copper, tin and porous steel and aluminum surfaces. We are currently testing it on other non-metal substrates like ceramic tile and marble.
