Radleigh carry out blast cleaning to both ferrous and non-ferrous fabrications using chilled iron grit and aluminium oxide respectively. The process of blast cleaning is used for the preparation of the substrate to remove mill-scale and oxides, and to provide a key prior to the application of paint, thermal spray or galvanizing, where a heavier deposit of zinc is required. It also highlights faults in welds, such as pinholes, that are not visible before the blast cleaning takes place.

img05There are a number of blast cleaning plants such as automatic for columns and beams, manual for large and complex fabrications, tumble blasters for smaller components and hand held units for etching glass or for the spot blasting and removal of individual coats.

The requirements for blast cleaning are extensively covered in BS 7079 Parts 0 - 6, together with ISO 8501 - 8504. The detail laid down in these standards is exhaustive and includes preparation methods and grades of preparation which are depicted by photographic examples introduced by the Swedish Institute of Corrosion in SIS 05 5900 and now incorporated into ISO 8501-1.

Although the blast cleaning of the steel substrate is clean we take random checks to ensure that there is no chemical contamination such as ferrous salts. These salts can effect the subsequent adhesion of the primer coat. We also ensure that the surface profile is up to specification by using the services of independent inspectors as well as keeping our own readings.

A well applied paint system will fail if the blast cleaning is flawed. We take every step to ensure that we get the preparation right.
