Some garage floors just need a coating. This one needed rebuilding first. The 480 sq ft slab on this Sackville, NS project had years of damage in it, and no coating on the market will hide that — it has to be repaired. We carried out extensive concrete repairs, prepped the slab properly and finished it in Basalt flake. Here is what a real garage floor restoration in Sackville actually involves.

Why you cannot coat over damaged concrete
This is the part homeowners are rarely told when they are comparing quotes. A floor coating is a surface. It bonds to the top few millimetres of your slab and it inherits whatever is happening underneath.
- Spalled or delaminating concrete — if the top layer is already letting go, the coating goes with it. You have simply paid to colour a failing surface.
- Old patches and previous repairs — mismatched, loose or crumbling patch material has to come out. It will not hold a coating and it telegraphs through the finish.
- Pitting, divots and low spots — these show as shadows and puddles in the finished floor, and they collect water and salt.
- Cracks — an untreated moving crack reappears through the coating, usually within the first winter.
Coating over any of that is how a floor fails in 18 months. Fixing it first is how a floor carries a 20-year warranty.
The repairs this Sackville floor needed
The middle photo shows the reality of the job — large areas of the slab cut back and rebuilt with repair mortar before a single drop of colour went down. Deteriorated concrete and failed patching were removed, the sound substrate was exposed, and the damaged areas were filled and levelled back to a consistent plane.
If your slab is in similar shape, it is worth reading our comparison of resurfacing vs replacing concrete in Nova Scotia before you assume the only option is a full tear-out. In most cases it is not.
How we restored the floor, step by step
1. Assess the slab honestly
Before quoting, we sound out the concrete and identify what is solid, what is delaminating and what has to come out. The repair scope is priced up front, not discovered on install day.
2. Diamond grind the full floor
The entire 480 sq ft was diamond ground with HEPA dust extraction — no dust storm through the house, no silica in the air. Grinding removes old sealers, paint, laitance and contamination, and opens a mechanical profile for the coating to key into. Acid etching does not do this, which is why so many DIY kits peel.
3. Repair, fill and level
Damaged areas were cut out and rebuilt, cracks and joints treated, and the repairs ground flush so the finished surface reads as one continuous plane.
4. Base coat and Basalt flake broadcast
The pigmented base went down and the Basalt flake was broadcast into it to refusal, giving the floor its depth, texture and thickness.
5. Scrape, vacuum and clear topcoat
Loose flake was scraped and vacuumed off, then the clear topcoat sealed the system — locking in the flake and creating the hard, easy-clean wearing surface.

Why Basalt flake works in a garage like this
Basalt is a composed, cool neutral with real geological character — greys with a slate undertone that hold up in both bright daylight and dim winter-evening lighting. On a restored floor it does something practical as well as decorative: the flake pattern and texture disguise the minor variations you will always have in a repaired slab, in a way a flat solid colour never could.
It also does the everyday work you want from a garage floor: it hides tire grit and dust, it gives the surface grip underfoot, and the broadcast builds genuine thickness rather than a thin painted film. Our guide to flake vs solid colour garage floors covers the trade-off in more detail.
Does concrete repair add much to the cost?
It adds labour and material, and it is the most honest part of any quote. A floor in good condition needs grinding and coating. A floor like this one needs demolition of the failed areas, rebuilding and levelling before the coating stage even starts — and any quote that does not include that line item is not quoting the same job.
Every Coastal Resin Resurface quote includes the preparation and repair the slab actually needs, so the number you are given is the number you pay. For general pricing by garage size, see our Nova Scotia garage floor coating price guide.
Backed by a 20-year warranty
We have completed more than 4,500 floors, and this floor carries a 20-year warranty. That warranty is only possible because of what happened before the colour went down. Preparation and repair are not the boring part of the job — they are the job. A great finished floor starts with fixing the concrete underneath it.
You can see the same principle applied on a larger residential project in our 700 sq ft polyurea garage floor in Antigonish.
Frequently asked questions
Can a damaged or spalling garage floor be coated?
Yes, but only after the damage is repaired. Deteriorated concrete, failed patches and spalled areas must be removed and rebuilt first, because a coating bonds to the surface it is applied to. Coating over failing concrete guarantees the coating fails with it.
Do I need to replace my garage slab or can it be restored?
Most slabs can be restored. Unless the concrete has structural failure or serious settlement, cutting out the damaged areas, rebuilding them and coating the floor costs far less than a tear-out and re-pour, and it can usually be completed in a fraction of the time.
How long does a 480 sq ft garage floor restoration take?
A floor needing extensive repair typically takes two days rather than one — repairs and preparation on the first day so the mortar can cure, then the coating system on the second. A floor in good condition can often be done in a single day.
What is Basalt flake?
Basalt is a decorative flake blend in cool neutral greys with a slate undertone. It is broadcast into the wet base coat and sealed under a clear topcoat, producing a textured, granite-like finish that hides dirt and disguises minor variation in a repaired slab.
Is the grinding process messy?
No. We grind with HEPA dust extraction attached at the tool, so the concrete dust is captured at source rather than settling through your garage and into the house.
What does the 20-year warranty cover?
Our coating systems are warrantied for 20 years against peeling and delamination when installed over properly prepared and repaired concrete. Preparation is included in every quote precisely so that warranty means something.
