Concrete Surface Preparation London Ontario

Concrete Surface Preparation in London, Ontario

Proper Surface Prep Is the Foundation of Every Long-Lasting Concrete Coating System.

Concrete surface preparation in London, Ontario, is one of the most important steps in any successful floor coating project. Whether the space is residential, commercial, industrial, or agricultural, the concrete must be properly repaired, profiled, cleaned, & prepared before any coating system is installed.

If preparation is skipped or rushed, coatings can peel, bubble, wear prematurely, or fail long before they should. We provide professional concrete surface preparation in the London area, including grinding, shot blasting, crack repair, coating removal, adhesive removal, moisture mitigation prep, & surface correction to ensure the new system bonds properly & performs long-term.

Why Concrete Surface Preparation Matters

Many coating failures do not start with the finish coat. They start with the slab underneath.

Concrete may look sound on the surface, but old sealers, weak concrete, dust, moisture, glue residue, paint, coatings, or surface contamination can all interfere with bond strength. If those issues are not addressed properly, even the best floor coating system can fail.

Proper concrete surface preparation helps:

Improve adhesion

Create the correct concrete surface profile

Remove contaminants that interfere with bonding

Repair damaged or weak areas

Reduce the risk of peeling, bubbling, or delamination

Support long-term coating performance

This is what separates a floor coating that lasts from one that fails early.

Why Solid Colour Epoxy Flooring Is Better Than Bare Concrete

Bare concrete may be functional, but it is porous, unfinished, & difficult to keep looking clean over time. It can absorb spills, create dust, & make a space feel cold or incomplete.

Solid colour epoxy flooring in London, Ontario, provides a sealed, reinforced surface that protects the slab while giving the floor a clean, professional appearance.

Here is how solid colour flooring compares to bare concrete:

No Dusting or Surface Breakdown

No Permanent Surface Staining

Cleaner, More Professional Look

Seamless Surface

Better Long-Term Value

If your current floor is plain, unfinished, or difficult to maintain, solid colour epoxy flooring in London, Ontario, provides a simple, durable upgrade.

Diamond Grinding & Shot Blasting in London, Ontario

Diamond grinding & shot blasting are two of the most important mechanical preparation methods used before installing floor coatings.

Diamond Grinding

Diamond grinding is used to:

Remove surface contamination

Profile the slab for adhesion

Open the surface of the concrete

Smooth uneven areas

Remove light coatings, paint, or adhesive residue

Prepare the slab for epoxy, grind & seal, or other systems

This method is commonly used for residential, commercial, & many industrial projects.

Shot Blasting

Shot blasting is used when a stronger, more aggressive profile is required. It is often used before moisture mitigation systems or in environments where the coating system requires a specific concrete surface profile. Shot blasting helps:

Create a deeper mechanical profile

Remove weaker surface material

Improve bond strength

Prepare slabs for higher-performance systems

The correct prep method depends on the condition of the concrete & the floor system being installed. Not every slab needs the same process.

Concrete Crack Repair & Surface Repair in London, Ontario

Surface preparation is not just about grinding. It also includes correcting defects in the concrete before the new floor system goes down.

Many coating projects begin with repair work, such as:

Concrete crack treatment

Pit & spall repair

Damaged edge repair

Weak surface removal

Joint cleaning & rebuilding

Patching of minor surface defects

Filling damaged areas with polymer or epoxy repair materials

These repairs help create a more uniform, sound substrate so the finished floor system performs better & looks more consistent.

Repair quality matters, especially on systems with a smooth or uniform appearance where flaws in the slab can show through more easily.

Coating, Adhesive & Flooring Removal

Many floors cannot be coated properly until the existing materials are removed.

We provide removal services for:

Old epoxy coatings

Paint & sealers

Glue & adhesive residue

Tile mastics

Carpet backing residue

VCT tile

Linoleum

Other surface contaminants that interfere with adhesion

Old flooring materials, failed coatings, & adhesive residues can prevent proper bonding if they are not fully removed. This is often one of the first steps before grinding, repair, & profiling begin.

Moisture, Contamination & Surface Readiness

Not every slab is ready for coating the moment the old floor is removed.

Some concrete floors have hidden issues, such as:

Moisture vapour transmission

Damp concrete

Contamination from oils, chemicals, or salts

Old penetrating sealers

Weak or deteriorated surface layers

Construction dust & residue

Previous coating failure

These issues can affect adhesion, finish quality, & long term performance.

That is why we evaluate surface readiness before installing the system. In some cases, moisture mitigation or additional prep steps are required before moving forward with the floor coating system.

Proper prep is about more than just making the floor look ready. It is about making sure the slab is truly ready to perform.

Where Concrete Surface Preparation Is Used

Concrete surface preparation in London, Ontario, is used across nearly every type of floor coating project.

This includes:

Garage Floor Coatings

Concrete Porch Coatings

Basement Floor Coatings

Retail & Showroom Floor Coatings

Lunch & Wash Room Floor Coatings

Office Floor Coatings

Warehouse Floor Coatings

Factory Floor Coatings

Aircraft Hangar Floor Coatings

Agricultural Floor Coatings

Every environment has different needs, but all of them depend on the same core principle: the concrete must be properly prepared before the finish system is installed.

Why Professional Surface Preparation Matters

Concrete preparation is one of the most technical parts of the flooring process, & it has a major impact on how well the final floor performs.

Improper surface preparation can lead to:

Weak bond strength

Peeling coatings

Bubbling

Premature wear

Uneven appearance

Moisture-related failure

Reduced the lifespan of the system

Professional preparation matters because it requires:

The right grinding or blasting method

The correct surface profile for the selected coating

Proper dust control

Repair knowledge

Moisture awareness

Attention to surface consistency & detail

We use professional surface preparation equipment, dust-controlled methods, & commercial grade repair materials to help ensure the slab is ready for long-term coating performance.

Frequently Asked Questions

What is concrete surface preparation?

Concrete surface preparation is the process of grinding, profiling, cleaning, repairing, & correcting the slab before a coating or finish system is installed.

Why is diamond grinding needed before epoxy?

Diamond grinding removes surface contamination & creates the proper profile so the epoxy can bond correctly to the concrete.

What is shot blasting?

Shot blasting is a mechanical preparation method that creates a stronger concrete surface profile. It is often used where more aggressive prep and cleaning is required.

Can you remove old coatings & glue?

Yes. We remove old coatings, paint, sealers, glue, tile adhesive, & other materials that interfere with proper adhesion.

Can you repair cracks before coating?

Yes. Crack repair, pit repair, spall repair, & joint repair are all common parts of the preparation process.

What happens if prep is skipped?

If the slab is not prepared properly, coatings can peel, bubble, wear prematurely, or fail long before they should.

Do all floors need moisture mitigation?

No, but some do. It depends on the moisture condition of the slab & the floor system being installed.

Is acid etching enough before epoxy?

No. In most cases, mechanical preparation such as diamond grinding or shot blasting is the proper way to prepare concrete for a long-lasting coating system.
