Question 1

Can Ottawa contractors resurface a badly pitted garage floor before epoxy application?

Accepted Answer

Absolutely — resurfacing a badly pitted garage floor before epoxy application is not only possible, it is often essential for a successful, long-lasting coating in Ottawa's demanding climate. Skipping this step is one of the most common reasons epoxy jobs fail prematurely, and in a city where road salt, freeze-thaw cycles, and snowmelt constantly attack concrete, getting the substrate right before any coating goes down is non-negotiable.

Question 2

How much does joint filling with polyurea cost before epoxy in an Ottawa warehouse?

Accepted Answer

Joint filling with polyurea before an epoxy coating system is one of the most important — and most frequently underestimated — line items in a commercial warehouse floor project. In Ottawa's climate, getting this step right is not optional. It is the difference between a floor that performs for a decade and one that fails within the first winter.

Concrete warehouse floors have two types of joints that need attention before any coating goes down. C

Question 3

Can Ottawa contractors fix a slab that sank near the garage door before applying epoxy?

Accepted Answer

Yes, Ottawa contractors can absolutely address a sunken slab section near the garage door before applying epoxy — and addressing it is not optional if you want a coating that lasts. Applying epoxy over a settled or uneven slab without proper remediation is one of the most common reasons coatings fail prematurely, and it is a mistake that costs far more to fix the second time around.

Question 4

Can epoxy be applied over mudjacked concrete in my Ottawa garage?

Accepted Answer

Mudjacking a settled garage slab is a smart fix for Ottawa's frost-heave problems, but the question of whether epoxy can go over it right away is one that catches a lot of homeowners off guard. The short answer is yes — epoxy can absolutely be applied over a mudjacked concrete slab — but the timing, surface condition, and moisture situation all need to be right before any coating goes down. Rushing this step is one of the most common and costly mistakes in the Ottawa market.

Question 5

What is the cost for a skim coat over rough concrete before epoxy in an Ottawa basement?

Accepted Answer

A skim coat over rough concrete in an Ottawa basement typically costs between $3 to $8 per square foot before epoxy application, depending on the severity of the surface irregularities and the specific leveling compound used. This preparatory step is often essential in Ottawa basements where concrete floors may have been poured decades ago with less attention to smoothness, or where settling and moisture cycles have created an uneven surface.

The most common approach uses a polymer-modified sel

Question 6

What is the price for full diamond grinding of a two-car garage floor in Barrhaven?

Accepted Answer

Diamond grinding for a standard two-car garage floor in Barrhaven typically costs between $800 and $2,400, or $2 to $4 per square foot, depending on the concrete condition and level of preparation required.

Diamond grinding is the gold standard for concrete surface preparation before epoxy coating application. This mechanical process uses industrial grinders equipped with diamond-embedded segments to remove the top layer of concrete, exposing fresh aggregate and creating the proper surface prof

Question 7

How much does it cost to remove tile thinset from a concrete floor before epoxy in Ottawa?

Accepted Answer

Removing tile thinset from concrete before epoxy application in Ottawa typically costs between $3 to $8 per square foot, depending on the thickness of the adhesive, the type of thinset used, and the concrete condition underneath. This preparatory work is absolutely essential because epoxy cannot bond properly to thinset residue, and any shortcuts here will lead to coating failure within months.

The removal process requires aggressive mechanical preparation, usually diamond grinding or shot blas

Question 8

What is the price for vacuum shot blasting a large commercial floor in Ottawa?

Accepted Answer

Vacuum shot blasting for large commercial floors in Ottawa typically costs between $3 to $8 per square foot, depending on the concrete condition, required profile depth, and project size. This aggressive mechanical preparation method is the gold standard for commercial epoxy applications where maximum adhesion and durability are critical.
