Bristol Metal Spraying & Protective Coatings

Water Blasting ready for abrasive blasting

We are able to carry out this process to meet the cleanliness requirements of internationally recognised standards using a wide range of blast media.

Components are cleaned using high pressure water to remove surface debris prior to abrasive blasting.

Abrasive blast media The Abrasive Blasting process can be used as a surface preparation, to remove corrosion deposits, to remove previously applied coatings and as a finishing process. We offer a wide range of blast media:

Used for surface preparation of ferrous substrates providing a clean profiled surface for coating application. Suitable for the removal of heavy corrosion deposits and the removal of previously applied coatings.

Used for the surface preparation of non-ferrous substrates to provide a clean profiled surface for coating application. Suitable for the preparation of thin gauge ferrous and non-ferrous substrates used at low pressure to avoid distortion. This media is often used to provide an aesthetic finish for architectural purposes and when coated with clear lacquer its gives an appearance similar to a metallic paint finish.

This media is used to provide a uniform smooth satin finish and it's primarily used on non-ferrous substrates. Common applications are as a suitable finish for use in the nuclear, medical and food industries were items have to be regularly cleaned or decontaminated. Glass bead can also be used to provide an aesthetic finish on building projects, objects of art and to reduce glare and shine where it would be problematic on items that are placed in prominent situations i.e. close to airfields or motorways.

This media is primarily used for the removal of existing paint systems. It is used extensively to depaint aircraft and military vehicles to allow for metallurgic inspection of the underlying substrate. This media is used when a surface profile is not required and where the use of steel grit or aluminium oxide is not permitted. The pressure at which the media is applied can be adjusted to control the removal of the existing paint system allowing each layer to be removed one at a time.

Glass grit will achieve a less reflective surface than that achieved using glass bead and offers a slight texture.

This media is used on site as an economical solution for surface preparation and cleaning of ferrous and non ferrous substrates where recycling and reclaiming of the abrasive media is impracticable.
