EPOXY FLOOR REPAIR AND RECOATING IN CALGARY.

Q: Will the repaired area match the rest of the floor?

For solid colour floors, a close match is achievable. For flake systems the broadcast pattern will be similar but not identical, since flake floors are inherently random and seamless matching is not possible. For metallic floors, matching is very difficult. We tell you this honestly before the job starts, not after.

Q: How do I know if my floor needs repair or a full redo?

You often cannot tell from the surface. A floor that looks like it needs a simple recoat can have widespread subsurface delamination that will not show until the new coating starts lifting too. The only reliable way to know is an in-person assessment with adhesion testing.

Epoxy floor repair in Calgary covers peeling, delamination, chemical damage, and worn topcoats. Every repair starts with a full slab assessment to determine whether a targeted patch, full recoat, or complete strip-and-recoat is required. Epoxy Floors Canada uses diamond grinding to re-profile the existing surface before applying fresh base coat and topcoat matched to the original system.

Not every failing floor needs to be torn out and started over. But some do. The difference comes down to what failed, why it failed, and whether the substrate underneath is still sound. We assess before we quote - and we'll tell you straight which situation you're in.

REPAIR OPTIONS AT A GLANCE

The right fix depends on what actually failed. Here are the three paths a repair can take - and only one is the right one for your floor.

SPOT REPAIR

Best Case

When It Works

Damage is contained to a specific zone. The coating around it is adhering properly and the concrete underneath is clean and dry.

What Happens

Failed area ground back to bare concrete, moisture tested, primed, and base-coated. New topcoat feathered in to match.

What to Expect

Colour match is close but may not be perfect. Flake floors may show the patch. We tell you this upfront.

Longevity

As long as the rest of the floor, assuming the original failure cause is resolved.

TOPCOAT RECOAT

Surface Only

When It Works

The floor looks tired but the base system is sound. No peeling, no blisters, no soft spots - just a topcoat that has run its life.

What Happens

Full floor cleaned, lightly abraded, moisture re-tested, fresh topcoat applied. No broadcast layer unless specified.

What to Expect

Floor comes back to near-new appearance. Deep scratches in the base coat may still show through a gloss topcoat.

Longevity

5-10 years depending on traffic and topcoat product selected. Same base coat, new surface layer.

FULL REMOVAL & REDO

Full Reset

When It Applies

Failing across more than a contained zone, active moisture, or the base coat itself has failed. Coating over it will fail again.

What Happens

Existing coating ground off to bare concrete, full diamond profile, fresh moisture test, full system reinstalled from MVB up.

What to Expect

A properly installed floor that won't fail again for the same reason. The only path to a long-term result when the substrate demands it.

Longevity

Same as a new install - 10-20 years depending on system and use.

WHAT'S WRONG WITH YOUR FLOOR?

The right fix depends entirely on what's actually failing. Here's how we read the four most common failure modes and what each one means for your options.

Peeling or Delaminating

Cause: Adhesion failure at the prep stage

The coating is separating from the concrete in sheets or flakes. This is almost always a surface preparation issue - insufficient concrete surface profile, contamination left on the slab, or coating applied over a previous floor that wasn't removed.

Spot repair if localized

Full redo if widespread

Bubbling or Blistering

Cause: Moisture vapor pushing up through the slab

Blisters that appear days or weeks after installation are a moisture signature. Vapor from below the slab builds pressure under the coating and lifts it. The moisture source has to be addressed first and an MVB barrier installed before any recoating can hold long-term.

Moisture test required first

Surface Wear or Dull Topcoat

Cause: Normal use - topcoat has run its course

The floor looks dull, scratched, or worn but isn't actually failing. The base coat and adhesion are intact - the topcoat has just seen enough traffic. A proper clean, light abrasion, and a fresh topcoat restore the floor without touching the base system.

Topcoat recoat

Soft Spots or Sticky Areas

Cause: Unmixed or under-catalyzed product

A section of floor that never hardened properly - stays tacky, picks up dirt, or feels soft underfoot. This is a mixing ratio failure. The affected area has to be ground out to bare concrete and redone from the base coat up.

Grind out and spot redo

WHAT WE CHECK BEFORE QUOTING

We don't quote repairs from a photo. Every job starts with an in-person assessment - because what's visible on the surface is rarely the full picture.

Moisture (In-Situ RH Testing)

We test the slab with a moisture meter before any primer goes down. If the reading is above 4.5%, any new coating needs an MVB barrier underneath - without it, the same failure will happen again.

Adhesion (Pull Test)

We pull-test the coating adjacent to the failed area. If it passes, spot repair is viable. If it fails, the failure is more widespread than it looks and the scope changes accordingly.

Failure Cause Identification

We look at the failure pattern, the underside of any lifted coating, and the concrete profile underneath. We won't recommend a repair without knowing the cause.

Scope (Map Full Damage Extent)

Visible damage is usually only part of the picture. We tap the floor to find hollow sections - coating that looks intact but has lost adhesion underneath. Repair scope is based on what's actually failing, not just what's visible.

THE REPAIR PROCESS

Whether it's a spot fix or a full redo, every repair follows the same methodical approach. No guesswork, no shortcuts.

Site Assessment

We visit the space, test moisture, pull-test adhesion, identify the failure cause, and map the full extent of damage. You get a written quote that covers exactly what's needed - and nothing more.

Preparation of Failed Areas

All failed or compromised coating is ground back to bare, sound concrete. Hollow sections found during tapping are included regardless of surface appearance.

Diamond grinding

Hollow section removal

Clean concrete

Moisture Seal (If Required)

If moisture is above 4.5%, MVB FC/RC goes down before any primer. On a repair job this step is especially important - moisture is frequently the original cause of failure.

Prime and Base Coat

Fusion Primer followed by the appropriate base coat. On a spot repair we build up to match the surrounding floor thickness. On a full recoat, a light scuff precedes primer to ensure mechanical adhesion.

Topcoat and Handover

Topcoat applied across the repaired or recoated area. We walk the floor with you at completion and hand over care instructions before we leave.

COMMON QUESTIONS

Can you coat directly over old epoxy?

Sometimes, but not without testing first. If the existing coating is fully adhered, properly abraded, and moisture levels support it - yes, a recoat can go over it. If there's any delamination, active moisture, or adhesion failure, coating over the top will reproduce the same failure. We pull-test before recommending anything.

How long does a repaired floor last?

As long as the rest of the floor, assuming the repair is done properly and the original failure cause is resolved. A spot repair where the cause wasn't identified and fixed will fail again in the same location. That's why the assessment step matters - we won't repair a symptom without addressing what caused it.

Will the repaired area match the rest of the floor?

For solid colour floors, a close match is achievable. For Flake systems the broadcast pattern will be similar but not identical - Flake floors are inherently random and seamless matching isn't possible. For metallic floors, matching is very difficult. We tell you this honestly before the job starts, not after.

How do I know if my floor needs repair or a full redo?

You often can't tell from the surface. A floor that looks like it needs a simple recoat can have widespread subsurface delamination that won't show until the new coating starts lifting too. The only reliable way to know is an in-person assessment with adhesion testing and moisture measurement.

My floor is only a year old and already failing. What happened?

Premature failure almost always comes down to one of three things: insufficient surface prep, moisture that wasn't tested or addressed, or product applied outside its temperature or humidity window. We'll identify which one applies and quote accordingly.

Do you offer warranties on repair work?

We stand behind our work on any job where we control the full scope - meaning we did the prep, addressed the moisture, and applied the full system. Warranty on a spot repair into someone else's existing floor is more nuanced and discussed at the assessment stage once we understand the conditions.
