More often is not better, and this is the one piece of paving maintenance that is routinely oversold. A sensible interval protects a surface; an annual one builds a layer that fails on its own.
Why your Edmonton driveway should not be sealed every year
Sealer is not paint and it does not simply sit there. Each coat adds thickness, and the combined layer grows stiffer than the asphalt underneath it, which moves with temperature while the coating does not.
Past a certain thickness that mismatch shows. The coating cracks in fine patterns and starts lifting in flakes, and from a distance a drive that has been sealed too often looks worse than one that was left alone.
The useful interval is longer than most quotes assume, and shade, traffic and exposure all move it. The residential job, the commercial one and the product used each change it a little, but none of them turns yearly coating into a good idea.
Due a coat
Deciding when
How to tell your Edmonton surface needs coating
Look at the colour
A black surface has coating left. A uniform grey one has oxidised and is at the point where a coat does some good.
Feel for loose stone
Run a hand over it. Loose grit coming away means the binder at the surface has gone, which is the condition coating is meant to delay.
Watch what water does
Water that soaks straight in is hitting bare asphalt. Water that beads and sits for a moment means there is still coating doing its job.
Deal with cracks first
If the surface is cracked, that work comes before any coat. Sealer poured over an open crack sinks into it and leaves a line that reopens.
What moves it
What changes the Edmonton coating interval
Sun exposure is the main one on a driveway. A surface in full afternoon sun oxidises faster than a shaded one, so two drives on the same street can genuinely need different intervals.
Use is the main one on a lot. Fuel and hydraulic drips attack the binder chemically rather than gradually, which is why commercial surfaces run on a shorter cycle than residential ones.
The product matters least of the three and gets discussed most. What is in the drum affects wear, what it costs follows from that, and a planned cycle is how the interval stops being guesswork and becomes a date.
No. Each coat adds thickness and the combined layer eventually cracks and flakes under its own stiffness, so a drive sealed every year ends up looking worse than one left alone.
The surface tells you. A uniform grey colour, loose grit coming away under a hand, and water soaking straight in rather than beading all point to a coat being worth doing.
Usually sun exposure. A surface in full afternoon sun oxidises faster than a shaded one, so two drives on the same street can genuinely be on different intervals.
Yes, because fuel and hydraulic drips attack the binder chemically in the places vehicles sit. That is a different and faster mechanism than weathering on a driveway.
Not in its first months. It needs to harden and finish releasing what is still in it first, and a coat applied too early will not bond properly to the surface.
Crack work comes first. Sealer poured across an open crack sinks into it and leaves a line that reopens within the season, so coating alone wastes the visit.
