How much more does polyaspartic cost than epoxy for a Toronto garage?
- Materials alone run about $5-$7/sq ft for epoxy versus $7-$10/sq ft for polyaspartic in the GTA, according to Polished Floors. For an average 480 sq ft two-car garage that works out to roughly $2,400-$3,360 for epoxy versus $3,360-$4,800 for polyaspartic, materials only.
Does polyaspartic really cure in one day in Toronto winters?
- In a heated garage, yes, according to Polished Floors. Polyaspartic cures by chemical reaction rather than evaporation, so it doesn't need warm air the way epoxy does; they routinely install in attached garages at 15-18°C with no portable heat and the floor is drive-ready the next morning. Detached, unheated garages need supplemental heat in January and February.
Will road salt eat through a polyaspartic coating?
- No, according to Polished Floors, polyaspartic is chemically inert to road salt. What can happen is salt brine working into a chip or a poorly sealed expansion joint and lifting the coating from below; keep the coating intact and salt isn't a problem.
Can polyaspartic be installed over an existing epoxy floor?
- Sometimes, per Polished Floors: if the epoxy is fully intact and well bonded, the surface can be sanded for adhesion and any chips or lifted edges ground out and patched first. If more than 10 percent of the existing epoxy is failing, full removal is the better call.
How long should a garage floor coating warranty be?
- Polished Floors' guidance for a residential GTA install is to look for a minimum of 10 years on polyaspartic and 5 years on epoxy, and to be wary of anything advertised as "lifetime" without a clear written list of what's covered.
