Coating removal and surface cleaning matched to the wall, not forced onto it.
A blasting job usually starts with a surface that is already telling the truth: failed coating over brick, graffiti sunk into masonry, corrosion on steel, or decades of buildup hiding joints that need repair. RSI selects the media, pressure, containment, and cleanup plan around one requirement: remove what does not belong “without damaging the underlying substrate.”
Commercial media blasting is controlled surface cleaning and coating removal. The point is not simply to blast harder; it is to remove the unwanted coating, contamination, graffiti, or corrosion while keeping the brick, stone, concrete, or steel underneath intact.
That is why RSI chooses the media and pressure around the building material and the desired outcome. Softer media is used where delicate masonry or historic facade material needs protection. More aggressive media may be appropriate for steel preparation or heavy coating removal, but that same approach can be destructive on older brick or stone.
On Upper Midwest commercial buildings, RSI most often uses media blasting as part of masonry restoration, steel preparation, coating removal, graffiti removal, and historic facade restoration. It is frequently the preparation step that makes the next phase possible: tuckpointing and mortar repair, commercial waterproofing, recoating, or a larger building facade restoration scope.
Containment is part of the restoration plan, not an afterthought. Depending on the site and environmental requirements, RSI may use tarping, negative air setups, dust collection systems, and other containment methods to control dust and protect the surrounding building environment.
A few of RSI’s Commercial Media Blasting for Building Restoration projects
A good blasting specification is not a media shopping list. It describes the substrate, the material to be removed, the level of cleaning required, the containment expectations, and the surface condition needed by the next repair or coating system.
Historic brick and stone need restraint. RSI starts from the principle that “softer medias are better for delicate masonry or historic restoration,” then controls pressure and dwell time so cleaning does not become erosion. The National Park Service warns that aggressive abrasive cleaning can damage historic masonry faces and mortar joints. [NPS Preservation Brief 6]
Steel preparation and heavy coating removal call for a different level of aggression. Where the next coating system specifies a blast-cleaning profile or visual cleanliness level, RSI prepares the surface to that project requirement rather than using a one-media default.
Containment is planned with the building in mind: tarping, negative-air setups, dust collection systems, and project-specific enclosure methods. When work may generate respirable silica, exposure control is governed by OSHA’s construction silica rule. [OSHA 1926.1153]
Blasting usually prepares the way for masonry repair, waterproofing, coating, or restoration systems. The finished surface has to be clean enough for the next scope without being overworked for the material underneath.
Exterior restoration work at 801 Washington shows the kind of access, sequencing, and facade coordination that makes blasting planning matter. On occupied commercial exteriors, the wall is only one constraint; the work zone, adjacent uses, and follow-on repair scope shape the plan.
Media blasting is a controlled cleaning or coating removal process using different blasting materials to clean surfaces or remove coatings without damaging the underlying substrate. We use different medias depending on the building material and desired outcome – softer medias for delicate masonry, more aggressive medias for steel or coating removal.

Upper Midwest buildings carry hard histories: freeze-thaw movement, deicing salts, older coatings, and facades that have already been repaired more than once. Blasting fails when the contractor reads only the coating and ignores the wall behind it.
Containment is a major part of blasting projects. The plan may include tarping, negative air, dust collection, and site-specific controls before production starts. [OSHA 1926.1153]
The most expensive mistake is assuming every surface can take the same blast. On sensitive brick or stone, the wrong media and pressure can “permanently damage the surface” before anyone realizes the cleaning line has crossed into removal.
RSI has seen damage caused by contractors “treating historic masonry like structural steel.” Steel preparation may need aggressive removal; a historic facade may need the lightest effective method and careful mockup approval before production.
Tarping, dust collection, and negative-air setups cannot be improvised after dust starts moving. On active commercial properties, containment protects tenants, sidewalks, neighboring spaces, and the cleanup budget.
Blasting that removes failed coatings but leaves masonry joints exposed is unfinished work. The surface should move into repair, coating, or waterproofing before weather and site conditions undo the preparation.
When blasting prepares an exposed slab, ramp, or walkway, RSI coordinates the surface profile with the requirements of traffic coatings and broader parking deck restoration scopes.
RSI treats media blasting as a controlled setup, not a commodity cleaning pass. The substrate, coating condition, desired outcome, and containment requirements are settled before the crew commits to the blast pattern.
Identify whether the work is masonry, stone, concrete, steel, or another surface, then confirm what needs to be removed: coating, graffiti, corrosion, contamination, or surface buildup.
Choose a softer approach for delicate masonry and historic restoration, or a more aggressive approach for steel preparation and coating removal. The building material and desired outcome drive the selection.
Set tarps, dust collection, negative-air controls, or other containment methods as the location requires. The goal is to keep the work zone controlled while protecting adjacent spaces and environmental requirements.
Remove the coating or contamination to the agreed condition, inspect the surface for damage or remaining material, and turn it over for repairs, waterproofing, coatings, or restoration systems.
On masonry, the right media and pressure matter because the goal is often to expose the wall for mortar repair or commercial brick repair, not remove the protective face of the wall.
Media blasting is a controlled cleaning or coating-removal process. Different blasting materials are used to remove coatings, graffiti, corrosion, or surface contamination while protecting the substrate underneath.
RSI chooses media based on the building material and the desired outcome. Softer media and lower pressure are better for delicate masonry or historic restoration. More aggressive media are used where steel preparation or coating removal requires it.
It can be, but only when the media, pressure, and method are matched to the substrate. Historic brick and stone are especially sensitive; the wrong approach can scar the surface, remove protective faces, and create long-term water infiltration problems. The National Park Service warns against aggressive abrasive cleaning on historic masonry. [NPS Preservation Brief 6]
RSI commonly uses media blasting on masonry restoration projects, steel preparation, coating removal, graffiti removal, and historic facade restoration. It is frequently one step in a larger repair or restoration sequence.
Containment is built into the project plan. RSI may use tarping, negative-air setups, dust collection systems, and other containment methods depending on the project location, occupied conditions, and environmental requirements. Silica exposure controls are governed by OSHA’s construction silica rule when applicable. [OSHA 1926.1153]
Yes. Blasting is often preparation work before repairs, coatings, waterproofing, or restoration systems are installed. A common example is removing decades of failed coating before tuckpointing and waterproofing can begin.
Often, yes. The feasibility depends on the substrate, access, containment, dust-control requirements, and building operations. RSI plans blasting around the work zone and the surrounding property so cleaning does not become a tenant, sidewalk, or adjacent-space problem.
RSI handles commercial media blasting across the Upper Midwest for masonry restoration, steel preparation, coating removal, graffiti removal, and historic facade work. We match the media, pressure, containment, and cleanup plan to the material and restoration goal.
