Metal Coating
A one-component, nano-based clear coating that seals metal against rust, corrosion, salt spray, acid rain and UV. Apply it to raw, primed, painted or powder-coated metal on tanks, piping, structures and equipment.
Why use it
- Protects against corrosion from moisture and salt
- Chemical resistance to acids and solvents
- Clear topcoat over raw, primed, painted or powder-coated metal
- Expected wear of 5+ years under normal conditions
- Easier cleaning and maintenance
- 5-year limited warranty
Where to use it
- Storage tanks and piping
- Structural steel
- Heavy equipment
- Railings and fixtures
Industries
- Oil & gas
- Marine
- Construction
How to apply
- Test a small, hidden area first to check adhesion and the look.
- Clean off oil, grease and dirt with XD Bio Cleaner, rinse with fresh water and dry. Wipe with a white rag and solvent: if the rag stays white, the metal is clean.
- Treat light to medium rust with Rust Remover. Sandblast or grind off heavy rust, scale and all slag on hot-rolled steel.
- Shake thoroughly before use, and again every 15 to 20 minutes, to keep the nanoparticles mixed.
- Spray with an HVLP gun (1.0 to 1.3 tip, about 25 to 30 psi). Where you cannot spray, use a fine bristle brush, a high-density foam roller or dipping, though the finish will not be as smooth.
- One coat: aluminum, copper, brass, bronze, stainless steel, galvanized steel, powder-coated metal and sound painted metal.
- Two coats: new iron and steel, primed with a rust and corrosion primer first. On unprimed steel or iron, apply the second coat wet over tack, no more than 15 minutes after the first.

Metal Coating: common questions
Which metals can I use it on?
Iron, steel, stainless steel, galvanized steel, aluminum, copper and bronze, whether raw, powder-coated, painted or primed.
Will it change how the metal looks?
It is clear and keeps the original look. On white paint or powder coat it can turn slightly off-white, so test a small area first.
How many coats do I need?
One coat on most metals, including aluminum, stainless, galvanized, powder-coated and sound painted metal. New iron and steel takes two: over a rust primer, or wet over tack within 15 minutes if unprimed.
How far does a 20 L pail go?
About 3,150 to 4,200 sq ft per coat, based on 600 to 800 sq ft per gallon. Rough or porous surfaces use more.
When can it get wet?
Make sure there is no chance of rain for at least 48 hours after coating. It is touch dry in 2 to 3 hours and fully cured in 7 days.
How long does it last?
Expected wear is 5+ years under normal conditions. Reapply as needed.
