Metal Protector® HD Quart


Metal Protector HD installs an enhanced semi-gloss finish on metal and painted surfaces in addition to installing a protective barrier to protect the finish of the architectural material against the damaging elements.

Category: SKU: MPHD-1QT



This product formulation contains high-performance acrylic designed to install durable, long-lasting protection to a variety of metal surfaces, including anodized aluminum, which is commonly found on window mullions, aluminum composite panels and painted or coated architectural surfaces.
This product shields metal surfaces from water and oxygen, and helps prevent these elements from aiding in corrosion of the metal; thus preventing the need for frequent restoration. A barrier is created between contamination found in the environment and the metal surface, forcing stain-forming contaminants to settle on the polymeric coating.  These contaminates are then easily cleaned during regular window cleaning maintenance services.
This coating will last at least three to five years depending on individual environmental conditions, and the frequency of maintenance services performed on the substrate.
This product creates an enhanced finish on the architectural surface. For invisible protection use Metal Protector MD.

For best adhesion and protection, first restore surface with Metal ReSurfacer® . Preparation of the surface is crucial to proper adhesion, and can be achieved with fine grit sandpaper or a solvent wipe.

If EnviRestore Metal Stain Remover is used to restore the surface, a temporary protection will be applied to the surface. It is important that the temporary protection is removed through a solvent wipe.

If contaminants are not removed prior to use, the adhesion ability of Metal Protector may be compromised. Protect unintended surfaces. Always test in a small, inconspicuous area prior to application. Make sure all product residues are completely removed from the surface prior to the application of the Metal Protector.


Apply product with a sponge roller, paint brush or sprayer. This product is similar to the application of paint. This product can be diluted with water for spray applications.

For a highly polished and enhanced surface, apply product evenly to the surface using a fine mist sprayer such as a HPLV (High-Pressure, Low-Volume) sprayer. A fine sponge or paint brush can also be used but may leave brush strokes on the surface.

The coating will begin to cure within 15 minutes and will not fully cure for 48 hours. No liquids may come into contact with the surface during that time.


In most circumstances, protected metal surfaces can be cleaned using only deionized water.
