Preperation and sanding of the metal surface is required

How to prepare your metal fence, railing, garage door or any other metal surface depends on the status of the metal. 

Understand that the preparation steps required depend on the state of your metal surface:

New or rusted metal surfaces need little preparation. Use a wire brush or sand paper to remove any flaking paint or rust. This will guarantee perfect adhesion of the metal paint on new metal/rusted metal. 

Only heavy rusted surfaces and areas require (some additional) proper preparation. Use a wire brush to remove the heavy rust, flaking paint and grime from the metal surface. Use sand paper on the heavy rusted areas until the surface looks even.

Preparation of new or bare metal

Preparation of new or bare metal

For new bare metal you only need to use a wire brush to roughen the surface. This will guarantee perfect adhesion of the paint on the new metal.

Preparation of rusted metal

Application on rusted metal requires in general some light sanding to clean and even the surface.

Wrap the paper around a sanding block and start sanding the surface. Fine sanding paper is perfect for this job since you’re only looking to smooth the metal surface slightly. Make sure to wipe away any dust before moving to the next step.

Preparation of heavy rusted metal

Preparation of heavy rusted metal

Heavy rusted metal and areas require more preparation. Use a wire brush to remove rust, flaking paint and grim from the metal surface. Coarse sand paper and probably more effort/ pressure is required to remove the heavy rust. Use sand paper on the heavy rusted areas until the surface looks even. Then, wipe away the dust with a duster or broom. This will remove any lingering dirt leftover. You are now ready to start masking.

Tip: Spot prime the heavy rusted area. To ensure a beautiful end-result, spot prime the heavy rusted areas. Let it dry before you start the first layer of Hammerite Ultima metal paint

Masking areas

Now you are ready to clean the metal surface and mask the areas you do not want to paint.
