Concrete Floor Shot Blasting

What Is Concrete Floor Shot Blasting and When Is It Needed?

Shot blasting is used to take the top off a concrete floor so coatings or new systems have something to grip onto.

A lot of floors look fine until you actually try to work on them.

Forklift traffic burnishes the surface over time — it goes almost shiny in places. Loading areas end up soaked with oil. Old epoxy might still be hanging on in patches, half bonded, half gone. Near entrances, sealers wear off unevenly where traffic is heaviest.

Then you’ve got areas where the concrete is starting to dust under pressure.

A quick clean won’t touch it.

Shot blasting is what’s used to strip it back and deal with all of that.

We carry out shot blasting across Meath, Louth, Cavan and Monaghan, mainly before coatings or flooring go down.

Where shot blasting is actually needed

It comes up once you realise the surface isn’t going to take anything new.

• floors worn smooth from traffic
• coatings stuck in bits across the slab
• oil and dirt worked into the surface
• weak top layers breaking away

A lot of warehouse floors are smoother than people realise until you try putting a coating back onto them.

That’s when it becomes obvious something more has to be done.

When does it come into play?

Usually before coatings go down.

Also when a floor has been sealed or painted before and needs to be brought back properly.

Or when it just won’t take anything new the way it is.

The kind of floors we shot blast

Warehouses, industrial units, factory floors — places that have taken a lot of use.

You’ll see:

• traffic lanes worn smooth
• old coatings hanging on in patches
• dusty sections where the surface is weak
• areas near doors more worn than the rest

Once blasting starts, you get a better idea of what you’re dealing with.

Shot blasting compared to grinding

Grinding works for certain jobs, but it won’t always clean a floor evenly.

Blasting tends to give a more consistent finish across larger areas.

On warehouse floors especially, grinding can leave uneven patches if the surface is already worn differently.

Getting the work done

The machines are loud enough — you’ll hear them running.

Dust extraction hoses are attached as we go, pulling material straight out. In indoor spaces, areas are usually sectioned off while the work is happening.

On busy sites, it’s done in stages around forklifts and deliveries.
