Concrete Shot Blasting to the Profile Your Coating Calls For

Not at this time. Crack and joint repair is handled by your coating installer or a concrete contractor. Shot blasting first exposes the cracks and gives the repair material a clean surface to bond to, and we’ll point out any cracks we see.

Concrete shot blasting is a mechanical surface-preparation process that propels small steel shot at the concrete surface and immediately recovers the shot, dust and removed material through an integrated vacuum system.

The process removes surface contaminants and creates a clean, textured concrete profile without the use of chemicals.

Shot blasting equipment is designed to operate with industrial dust collection, capturing the majority of generated dust and debris during the preparation process.

No concrete preparation process should be described as completely dust-free, but properly operated shot-blasting equipment with dust collection is far cleaner than prep methods that don't collect dust as they work.

Typically, neither.

Shot blasting is a dry mechanical preparation process, which means there is generally no chemical stripping and no wastewater created by the shot-blasting process itself.

That also means the prepared surface can often move quickly into the next stage of the project.

Shot blasting uses steel shot to clean and texture concrete. It's efficient on large, open floors that need a specified profile for a coating or overlay.

Grinding uses diamond tooling. It's better suited to edges, tight areas, and smoothing or leveling. We use shrouded edge grinding where the blaster can't reach. The right method depends on your floor and what goes on it next.

CSP stands for Concrete Surface Profile.

Concrete profiles range from relatively smooth to increasingly aggressive textures. The correct CSP depends on the coating, overlay or flooring system being installed.

BlastTex can prepare concrete to the specified profile when project requirements are provided.

Yes, when the manufacturer's requirements or project specification are provided. Product selection, moisture testing, installation, warranty, and final acceptance stay with the manufacturer, installer, and owner.

Yes. Epoxy, polyaspartic, and polyurea installers, striping contractors, and general contractors hire us to handle the concrete prep. Send the spec or product data sheet with the required CSP and we prep to it.

We work ahead of your crew, including nights and weekends, and we never sell or install coatings, so the client relationship remains yours.

Empty the garage, then the slab needs to be clean, dry, and profiled. That means old sealers, paint, and peeling coating removed and the surface opened up to the texture, or CSP, your coating’s instructions call for.

Store-bought kits often say to acid etch. Etching leaves a shallow profile and can’t remove curing compounds or oil, and leading coating makers recommend mechanical prep like shot blasting instead. We shot blast and grind the edges for $1,500 for up to 400 sq ft within 50 miles of Hurst.

The two most common reasons are improper floor prep and coating concrete that isn’t fully dry.

Improper prep. Epoxy needs clean, textured concrete to grip. Dust, oil, old sealers, curing compounds, and smooth, weak surface paste all get in the way. Acid etching from a store-bought kit leaves only a shallow profile and can’t remove curing compounds or oily deposits, which is why leading coating makers recommend mechanical prep like shot blasting instead.

Coating too soon after rain. After a rain, concrete can look dry on top and still be holding water inside. Rain blowing or running into the garage, water dripping off cars, and moisture coming up through the slab all add to it. Water between the slab and the coating weakens the bond, and the epoxy can blister or peel later even if it seemed to cure fine. Give the slab time to dry out completely, and follow your coating maker’s moisture guidelines before it goes down.

What about “hot tire pickup”? That’s when warm tires lift the coating as you pull out. It’s mostly a coating problem: thin, low-solids or water-based epoxy kits soften under hot tires. A weak bond from poor prep makes it worse. Ask your installer about a coating rated for hot tires, and we’ll make sure the concrete under it is ready.

Shot blasting can remove topical layers. Deeply embedded stains and contamination may need extra passes or another method, and some may never fully come out.

Send photos and we will tell you what to expect before we start.

It can remove contaminated surface material and profile the concrete, but it isn't a guaranteed stain remover for oil that has soaked deep into the slab. If you're coating afterward, the coating manufacturer's contamination and prep requirements should be reviewed before we start.

Cracks, pitting, patches, failed repairs, weak concrete, and hidden coating layers sometimes don't show until prep begins. If what we find differs from the approved scope, we'll stop, show you, and price the added work on a written change order before doing anything beyond it.

There isn't one responsible price per square foot for every floor. Square footage, required CSP, existing coatings, floor condition, number of passes, access, obstacles, edge work, travel, and scheduling all play a part, so we look at the actual project first.

Starting points: commercial shot blasting and surface prep $2,500 minimum; residential garage floors and driveways from $1,500 (up to 400 sq ft). Minimums include mobilization within 50 miles of Hurst (76053).
