Blasting Jobs Contractors Quote For

Each job needs different media, pressure and equipment, so say what the item is made of when you request quotes.

How Sandblasting Works

1. Assess. The contractor checks the material, size, current coating and condition, from photos or a visit. Soft or old surfaces get a test patch.
2. Choose media and method. Angular grit for rust and paint, steel shot for heavy steel, glass bead for a satin finish, soda or wet blasting for gentler work.
3. Prepare. Parts are stripped or masked, and dust is contained so nearby cars, plants, windows and neighbours are protected.
4. Blast. The surface is cleaned to the agreed standard or profile.
5. Clean and protect. Dust and spent media are removed. Bare steel is primed or coated quickly, because it starts rusting again within hours in coastal air.

Ask each contractor which media they will use and what happens to the surface after blasting.

Blasting Media

• Mineral and slag grit. Garnet, copper or iron slag and aluminium oxide. Angular, fast and leaves a profile that paint grips.
• Steel shot and steel grit. Recycled in blast rooms and wheel machines. Shot is round and peens, grit is angular and cuts.
• Glass bead. Round beads that clean and leave a satin finish without much profile.
• Soda. Sodium bicarbonate. Soft, removes coatings and grime, does little to the substrate.
• Wet or vapour blasting. Media mixed with water. Less dust and a smoother finish.

Workshop or On-Site

• Workshop. Items that can be moved go into a blast cabinet or booth. Controlled, faster and usually cheaper per item.
• On-site. Buildings, tanks and fixed steelwork are blasted where they stand. Needs space, a compressor, containment and clean-up, which adds cost.

Ballpark prices so you can sanity-check a quote. They are not quotations and no contractor is bound by them.

Material, surface area, condition, access, transport, masking and the finish needed after blasting set the final price.
