FAQs

Can I use this paint indoors?

No, this product is specifically formulated for outdoor use due to its solvent-based composition.

How many coats should I apply?

For maximum protection, apply 3 to 4 light, even coats.

Do I need to remove all the rust first?

No, this product is designed to be applied directly over rusty surfaces, though you should remove any loose or flaking material with a wire brush.

How long does the paint take to dry?

The minimum drying time is 1 hour, with a maximum drying time of 2 hours, and you can recoat after 15 minutes.

Is this product safe for children?

No, it contains flammable hydrocarbons and must be kept out of reach of children at all times.

What should I do if the can is accidentally heated?

The can is a pressurized container and may burst if heated; keep it away from heat, sparks, and open flames, and never store it in temperatures exceeding 50 degrees Celsius.

Troubleshooting

The nozzle is clogged and won't spray.

Ensure you invert the can and spray for 2 seconds after every use. If already clogged, check if the nozzle can be cleaned with a solvent-compatible thinner.

The paint is reacting with the existing surface.

If a test patch shows a reaction, you must remove all old paint from the surface before applying Hammerite.

Poor adhesion on metal.

Verify the material is not bare zinc, aluminum, or galvanized. These surfaces require an additional primer step before applying the aerosol.

  • Suitable for direct application on existing rust

Setup, Compatibility & Care

Before use, store the can at room temperature for at least 2 hours to ensure optimal spray consistency. Shake the can vigorously until you hear the agitator ball, then continue for 3 full minutes.

Compatibility note: While effective on most metals, bare zinc, aluminum, or galvanized surfaces require a specific metal primer before application. Always perform a test patch on previously painted surfaces; if there is no reaction after one hour, you may proceed. To care for the dispenser, always invert the can and spray for 2 seconds after each use to clear the nozzle and prevent future blockages.
