Industrial sandblasting and abrasive blasting in Montreal

Induscoat provides sandblasting (abrasive blasting) for industrial and commercial sites in Montreal, with a mobile unit that comes to you: steel, tanks, structures, concrete and machinery. We work out of LaSalle, on the Island of Montreal, and the coating goes on right after the blast. Send photos and dimensions and you receive a quote within 24 business hours.

What surfaces do you blast in Montreal?

We blast steel and concrete in plants, warehouses, terminals and commercial buildings: frames and beams, walkways, stairs and guardrails, tanks (outside and inside), piping, bins and chassis, production machinery, and concrete slabs and walls that are about to be coated.

The goal is always the same: remove rust, mill scale and old paint, then leave a clean, rough surface the new coating can bond to. Work is carried out by our crews and qualified subcontractors. The service is for industrial and commercial sites only: we do not blast houses, decks, cars or furniture.

Is the blasting done at our site or in a shop?

At your site. The mobile unit arrives with the compressor, blast pot, abrasive, dust collector and containment material. For a frame, a tank or a machine anchored to the floor, it is the only realistic option: nothing to dismantle, nothing to truck, and nearby production can carry on behind the screens.

Before the trip, we settle truck access, air and water supply, site permits (work at height, confined space, lockout) and the schedule with you. Work can be done on day, evening, night or weekend shifts, whichever disturbs your operations least.

Which SSPC preparation grade should you ask for?

The one the coating data sheet requires, and no more. SSPC/AMPP grades describe what may remain on the steel after blasting. Brush-off (SSPC-SP 7) removes whatever is no longer bonded. Commercial blast (SSPC-SP 6) is enough for most atmospheric paints. Near-white metal (SSPC-SP 10) is specified for zinc-rich primers and immersion service. White metal (SSPC-SP 5) is kept for the most severe services.

Surface profile matters as much as cleanliness: it is measured on site and compared with the range set for the product. A higher grade than needed costs time and abrasive without making the coating last longer.

Dry, wet, glass bead or dry ice blasting: which one?

Dry blasting is still the fastest on heavy steel and gives the sharpest profile. Wet blasting, often called dustless blasting, wets the abrasive: dust drops instead of drifting, which makes it useful near neighbours, vehicles or a running line. It leaves a slurry to collect and needs an inhibitor against flash rust.

Glass bead cleans and satin-finishes stainless steel, aluminum and machined parts without cutting into the metal. Dry ice creates no profile and leaves no abrasive behind: it is used to clean machinery, moulds and equipment that cannot get wet. The choice depends on the substrate, the planned coating and what surrounds the work area.

How do you control dust and lead in the middle of the city?

With containment. In an urban setting, the blast zone is closed off with tarps or an enclosure, kept under negative pressure and connected to a dust collector, so that neither dust nor abrasive escapes to the street, the neighbours or the rest of the plant. Spent abrasive is collected and removed at the end of each stage.

Old paint on structures and tanks often contains lead. A sample is analyzed before work starts. If lead is confirmed, the job follows CNESST requirements: sealed enclosure, respiratory protection, worker decontamination, and handling of the waste as regulated material.

Who applies the coating after blasting?

We do, within the same shift. Freshly blasted steel starts rusting again as soon as moisture from the air settles on it. The surface blasted during the day therefore gets its primer before the shift ends, once dust is removed and dew point is checked.

Coatings are our core business: blasting is only the first step. The system (zinc-rich primer, epoxy, polyurethane topcoat, immersion lining) is chosen for the site's exposure, then every coat is measured and recorded. You deal with one contractor for preparation, painting and the inspection file.

Which parts of Montreal do you travel to?

Everywhere on the island and around it. In the southwest and west: LaSalle, Lachine, Dorval, Saint-Laurent and Pointe-Claire. In the industrial East End: Anjou, Saint-Léonard, Montréal-Est, Pointe-aux-Trembles and Rivière-des-Prairies. Along the river: the port area, Hochelaga-Maisonneuve and the Sud-Ouest.

Off the island, the same mobile unit travels to Laval and the North Shore, and to Longueuil and the South Shore. The trip from LaSalle is short, so a job can be split into several visits when production requires it.

Frequently asked questions

Do you have a blasting shop in Montreal?

No. Induscoat does not run a walk-in blasting shop. Our head office is in LaSalle, on the Island of Montreal, and our mobile crews come to you with blasting, containment and painting equipment. For a small removable part, say so in your request: we will tell you whether the work can be done at your site.

How much does sandblasting cost in Montreal?

Pricing is by quote. It depends on area, the condition of the steel or concrete, the SSPC grade required, access, containment, the presence of lead and the schedule. Our sandblasting cost guide explains each factor. Send photos and dimensions: quote within 24 business hours.

Sandblasting, abrasive blasting, grit blasting: is it the same thing?

Yes. All three terms mean propelling an abrasive with compressed air. Silica sand is no longer used because of the risk to the lungs: today the media is garnet, slag, steel grit, glass bead or other abrasives, chosen for the substrate.

Can you blast inside a running plant?

Yes, zone by zone, under containment with dust collection, or by wet blasting when dust must be kept to a minimum. Adjacent equipment is protected. Areas too close to sensitive devices are done during a shutdown.

Do you blast for homeowners?

No. We serve industrial and commercial sites: plants, warehouses, terminals, commercial buildings and municipal assets. We do not blast houses, cars or furniture.
