Mobile sandblasting in Melbourne allows paint, rust and contamination to be removed at the location of the asset. It is particularly useful for machinery, steel structures, concrete walls, bridges, heritage elements and other items that are difficult or expensive to transport. Modern mobile services may use wet abrasive blasting rather than traditional dry “sand” blasting to reduce airborne dust.

All Blast operates onsite mobile blasting units for commercial, industrial and domestic work. This article explains what happens from quote to completion, which factors influence cost and what clients can do to prepare a site for a smoother project.

What happens before a mobile blasting quote?

The contractor first needs to understand the material, existing coating and desired result. Photographs can support an initial discussion, but a site inspection or test patch may be necessary when layers are unknown, access is complex or the substrate is sensitive. Suspected lead paint or other hazardous residue must be identified early.

Useful information includes approximate dimensions, site address, working hours, power or water restrictions, drainage locations, nearby operations, access height, lifting needs and the coating that will follow. A precise brief allows the contractor to price containment and cleanup rather than relying on assumptions.

Which cost factors matter most?

Surface area is only one factor. Thick elastomeric coatings, bitumen, multiple paint layers and heavy corrosion can require more passes than a thin, weathered coating. Intricate steelwork, bolts, corners and lacework also take longer than open flat areas. Height access, scaffolding, traffic management and shutdown restrictions can influence labour and equipment.

Waste handling changes with the removed material. Ordinary paint debris and abrasive differ from lead-contaminated waste or residues affected by oils and chemicals. The quote should state whether containment, removal, transport and disposal are included.

How is the site prepared?

Preparation usually includes an exclusion zone, protection of glazing and finished surfaces, isolation of nearby equipment, drain protection and confirmation that the asset is safe to work on. Vehicles, stock and loose items should be moved beyond the likely work area. Sensitive alarms, cameras and air intakes may need covers or temporary isolation.

Clients can reduce downtime by arranging permits, access equipment and shutdown approvals before the crew arrives. A nominated site contact should be available to confirm boundaries and respond if hidden defects or extra coating layers are discovered.

How is quality checked?

Quality should be checked against the agreed outcome. For appearance cleaning, that may be an approved test patch and consistent visual finish. For industrial coatings, inspection may include visible cleanliness, surface profile, dust, salts, moisture and the interval before priming.

Blasting can reveal corrosion pits, cracks, porous repairs and previous patching that were concealed by paint. These are substrate conditions rather than blasting defects. The project programme should allow the relevant trade to assess and repair them before the new finish is installed.

How can downtime and cost be reduced?

Bundle accessible areas where practical, provide accurate photos and coating information, and remove obstructions before mobilisation. Coordinate the blasting and coating teams so freshly prepared surfaces are not left exposed. For operating facilities, divide the project into zones that can be isolated and returned to service progressively.

Lowest price should not be the only selection criterion. An incomplete allowance for containment, access or disposal can create variations later. Compare scope, method, finish, exclusions and cleanup requirements on the same basis.
