The accurate preparation of surfaces prior to painting is critical and requires the utmost care if consistently clean and corrosion-resistant surfaces are to be achieved.
The first step of the surface preparation process for large welded structures is shot-blasting. Shot-blasting removes any rust and leaves the surface of the metal feeling ‘rough’ which improves paint adhesion in the coating operation.
Once an item has been shot-blasted it is important that all ‘shot’ material – sand, in most cases - is removed. CTI Systems' dedicated de-sanding device safely rotates and tilts each pre-painted part several times so that any excess ‘shot’ falls away to leave the surface of the component ‘shot’ free.
