Why Metal Spray Coatings Are Sealed

A metal sprayed coating is a complete protective system in itself. A sealant enhances that protection and gives the coating a better appearance.

The sealant fills the pores of the coating, which reduces the exposed metal area and the rate at which the coating dissolves. It also smooths the surface, so grime and contaminants are not retained.

What Sealing Provides

Filled Pores

Less exposed metal, and a lower rate of coating dissolution.

A Smoother Surface

Grime and contaminants are not retained, which reduces surface attack.

Easier Maintenance

The coating stays cleaner and more attractive.

A Base for Paint

Sealed coatings accept paint, giving structures a longer life.

Process Steps

Diagram in four stages: steel is blasted, metal sprayed, a close view shows sealer filling the pores of the coating, and the result is tested
Why It MattersSprayed metal coatings have fine pores. Sealing fills them, which slows corrosion and extends the coating's life. Illustrative diagram.

  1. Blast

    The steel is blasted clean.

  2. Spray

    Zinc or aluminium is applied within hours.

  3. Seal

    The sealant is applied over the metal coating.

  4. Test

    Thickness and adhesion are measured and recorded.

Applications

Sealing is applied over metal spray coatings on structures in service.

Frequently Asked Questions

Is sealing always required?
No. A metal sprayed coating is a complete protective system in itself. A sealant enhances that protection.
Can paint be applied over a sealed coating?
Yes. Sealed coatings provide a base for paints, giving structures a longer life.
Is sealing carried out on site?
Yes. Where metallizing is carried out at your site, the sealant follows it there.
