Our Process
Our Process
Polished concrete is cured concrete mechanically refined with progressively finer diamond tooling, treated with a penetrating silicate densifier, and finished to a specified aggregate exposure and sheen. Harrowgate self-performs repairs, grinding, honing, densification, polishing, edge work, joint treatment, and protective guard application across the GTA.Polishing does not create a plastic film and it cannot make every slab visually uniform.

FAQ
Polished Concrete Floors FAQ
What aggregate exposure can polished concrete achieve?
Options range from cream polish with minimal aggregate, through salt-and-pepper fine exposure, to medium or deep coarse aggregate. The slab's flatness, finishing, aggregate distribution, repairs, and cover limit the result. Harrowgate produces a site mock-up because photographs cannot predict the appearance of a specific slab.
How many grinding steps are required?
The number depends on coating removal, desired exposure, concrete hardness, and final sheen. A floor may require coarse metal-bond cutting, transitional tooling, and several resin-bond steps through 400, 800, or 1500 grit. Skipping a step before its scratch pattern is removed produces visible defects at final polish.
Does polished concrete need a densifier?
Yes, most professional systems include a penetrating silicate densifier. It reacts within the cement paste to harden and dustproof the surface, supporting later polishing. It does not create a topical coating, repair cracks, or make the slab waterproof. Product type and application stage follow the approved polishing system.
Can old stained concrete be polished?
Often, but results depend on stain depth, oil penetration, previous adhesives, curing compounds, and patch history. Grinding removes only material within the selected exposure depth. Harrowgate prepares test areas to show what remains visible and whether deeper removal, repairs, a topping, or an opaque coating is more practical.
When should joints be filled on a polished floor?
Construction-joint filling is coordinated after sufficient slab shrinkage, typically later than initial placement. Semi-rigid filler supports edges under hard wheels and is shaved flush. Expansion and isolation joints must remain flexible. Filling every joint rigidly or filling too early causes gaps, cracking, or restraint as the slab moves.
Is polished concrete slippery?
A correctly refined clean floor can provide suitable dry traction, but water, oil, dust, and maintenance products control real conditions. Harrowgate matches final refinement and guard to the use, then recommends neutral cleaning. Waxes or residues can change traction and should not be introduced without reviewing compatibility.
What information is needed to price polished concrete?
Provide area, slab age, drawings, existing finish and adhesive history, desired aggregate exposure and sheen, joint plan, repair expectations, lighting, fit-out sequence, and access constraints. A site review and mock-up determine tooling, grinding depth, edge effort, repair appearance, protection, and the realistic visual range for the slab.
