Graniflex coating · Toronto and the GTA
Graniflex Contractors Toronto
A porch over a cold cellar. A balcony that leaks. A pool deck that cracks every spring. Graniflex is the coating that moves with the concrete instead of cracking with it.
Toronto Concrete Repairs installs Graniflex, a flexible, waterproof, granite look coating, on porches, steps, balconies, pool decks and walkways across Toronto and the GTA. Cracks repaired first, slab ground, coating bonded, finished in one to two days with a ten year written warranty.
Quick answer
What is Graniflex, and when is it the right choice?
Graniflex is a concrete coating system built on a flexible polyurea base coat, with a decorative flake broadcast that gives it the look of granite, and a clear polyaspartic topcoat. The base coat stays rubbery after it cures, so it stretches over hairline cracks instead of cracking with them, and it's waterproof, which is why it's the right system for a porch over a cold cellar, a balcony over living space, or a pool deck that takes water and chemicals all summer. It's also UV stable, so it doesn't yellow outdoors the way epoxy does, and the flake gives it grip when wet. Toronto Concrete Repairs installs Graniflex over repaired, ground concrete in one to two days, with a ten year written warranty. It's priced per project, above a standard overlay and well under replacement; text three photos and you'll have a written price within one business day.
The real decision
Graniflex vs concrete overlay vs epoxy
Three ways to put a new surface on sound concrete. They're not interchangeable, and the wrong one on the wrong surface fails within a couple of winters.
| Factor | Graniflex | Concrete overlay | Epoxy or flake epoxy |
|---|---|---|---|
| What it is | Flexible polyurea base, granite flake, polyaspartic top | Thin polymer modified cement bonded over the slab | Rigid resin coating, with or without flake |
| Best for | Porches over cold cellars, balconies, pool decks, steps, anything that leaks or moves | Driveways, walkways, patios, large areas where you want a concrete look | Garage and basement floors, interiors, dry slabs |
| Hairline cracks | Bridges them; stays sealed as they move | Can telegraph through over time | Cracks with the slab |
| Waterproof | Yes | No, sealed but not a membrane | Not outdoors |
| Outdoors and UV | UV stable, doesn't yellow | Fine with sealer maintenance | Yellows and chalks in sun |
| Warranty | 10 years | 3 years | Per job |
| Cost | Priced per project, above an overlay | $7 to $10 per sq ft | $3 to $12 per sq ft |
Our honest take: if the concrete is sound and dry and you want it to look like concrete, an overlay is the better value. If it's a garage or basement, epoxy or polyaspartic. If water is getting through it, if it has hairline cracks that keep coming back, or if it's a pool deck, Graniflex is the one that's still there in ten years, and that's what the warranty says.
Where it belongs
Where we install Graniflex in Toronto
Porches over cold cellars
The most common Graniflex job in Toronto. Older homes have a cold cellar under the porch, and water coming through the slab ends up on the shelves. Graniflex is the membrane that stops it.
Steps and landings
Nosings rebuilt, cracks filled, then coated as one piece. Grip when wet, no more chipping edges, salt doesn't touch it.
Balconies and walkouts
A balcony over a living room or a walkout over a basement needs a surface that's waterproof and flexible. Graniflex does both, with the drain and the edges detailed properly.
Pool decks
Cracks, chemicals, bare feet and freeze and thaw. Graniflex stays cool, grips when wet, resists chlorine and salt systems, and moves with the deck instead of cracking with it.
Patios and walkways
Where a plain overlay would do but the slab has hairline cracks that keep coming back, Graniflex is the one that stays sealed.
Commercial entrances and condo balconies
Building entrances, condo balconies and stairwells, done in phases with the ten year warranty a board can file.
The process
How we install Graniflex
The coating is only as good as what's under it. The first two steps are where cheap installs cut corners and where the warranty is earned.
Assess
From photos or on site. The slab has to be sound and not moving. If the porch is pulling away from the house or the deck has sunk, we say so and quote the alternative.
Repair and grind
Broken nosings and edges rebuilt, cracks opened and filled, then the whole surface diamond ground to open the concrete so the base coat bonds to it, not to old sealer or paint.
Polyurea base coat
The flexible, waterproof layer. Rolled on, edges and drains detailed, and this is the layer that bridges the cracks and keeps the cold cellar dry.
Flake broadcast
Granite look flake broadcast to full coverage into the wet base coat, then scraped flat once it's set. This is the colour and the grip.
Polyaspartic topcoat
Clear UV stable topcoat locks the flake in. Walk on it the next day. Furniture and planters after a few days, with the dates in your quote.

Why Toronto Concrete Repairs
Why the installer matters more than the product
Graniflex is a good system. It fails when it's put over loose concrete, unfilled cracks or a slab that's still moving. We also repair and replace concrete, so we have no reason to coat something that should be fixed first.
Reviews
What homeowners say about their coated concrete
★★★★★ 4.8 · 100+ Google reviews · As seen on CTV's Marilyn Denis Show
★★★★★
Balcony repaired, waterproofed and coated
I hired them to repair a large crack in my balcony floor and to waterproof and resurface it with Graniflex. The job was scheduled quickly, the crew were efficient, careful and pleasant, and I'm extremely happy with the finished product. Would strongly recommend.
★★★★★
1,000 square foot pool deck
We hired them to repair our very old and cracked pool deck and then apply Graniflex. They took the time to explain the process and the options, the work was done on schedule, and the deck looks brand new. It's cool underfoot and not slippery when wet.
★★★★★
Looks like a brand new porch
This is the second project I've hired Toronto Concrete Repair to complete, and once again they did a phenomenal job in record time. They repaired the concrete on my front porch and steps and applied a decorative coating. Incredible work, it looks like a brand new porch.
Questions
Graniflex: common questions
Graniflex is priced per project, because the cost depends as much on the repair and prep underneath as on the coating itself. It sits above a standard concrete overlay ($7 to $10 per square foot) and well under replacement, and for a porch, steps or a balcony it's usually a one to two day job. Text three photos and you'll have a written price within one business day, with an overlay or a repair priced beside it where either would do.
Yes, if the water is coming through the porch slab, which it usually is. The polyurea base coat is a continuous waterproof membrane, and because it's flexible it stays sealed when the slab moves through winter. We detail the edges where the porch meets the house, which is where most leaks start. If water is coming in through the foundation wall rather than the slab, that's a different fix and we'll tell you.
It carries a ten year written warranty, the longest on anything we install. Installed over sound, repaired, ground concrete and kept clean, it lasts well beyond that. The polyaspartic topcoat is UV stable, so unlike epoxy it doesn't yellow or chalk outdoors.
No. The flake broadcast gives the surface a texture that grips in rain, snow and around a pool, and we can increase the texture where you want more. It's also cooler underfoot than bare concrete, which is why pool owners choose it.
Over hairline cracks, yes; that's the point of the flexible base coat. Over structural cracks, no. Cracks are opened and filled before coating, and if the slab is still moving (a porch pulling away from the house, a deck that's sunk), coating it hides the problem for a season. We assess that first and quote the right fix.
Granite look flake blends from light greys and sandstones through to dark charcoals, with a few earth tones. We bring sample boards to the site visit so you see them against your brick and railings rather than on a screen.
Walk on it the next day. Furniture, planters and heavy use after a few days, with the exact dates in your quote. The whole install is one to two days on site for a typical porch, steps or balcony; pool decks run a little longer.
Overlay if the concrete is sound and dry and you want it to look like concrete; it's the better value on driveways, walkways and big patios. Graniflex if water is getting through, if hairline cracks keep returning, or if it's a pool deck or balcony. We install both and price them side by side. See concrete overlays.
