What Fails On A Sarnia Garage Slab
The door line goes first. That strip takes the most water and the most temperature swing, and it is usually where the pitting starts.
Then come the tyre tracks. Warm tyres sitting on a soft or thin coating pull it up when you drive off, which is why the build thickness and the top coat matter more than the colour.
Then the dust. A breaking-up surface throws off fine grey powder that settles on whatever is stored out there and walks into the house on your shoes.
Finally the stains. Oil, brake fluid and antifreeze soak into open concrete and never come out.
How We Build A Garage Floor
Everything comes out and the walls get masked.
The slab is diamond ground, not acid etched. Grinding is what gives the resin something to hold onto.
Cracks and spalled edges are cut out and repaired with a compound that takes coating.
We take a moisture reading and choose the primer from it.
Base coat goes down and chip is thrown into it until the surface will take no more, which is what keeps the colour consistent corner to corner.
Once it has gone off, the loose chip is scraped and vacuumed away and the polyaspartic goes on with aggregate through it for grip.
Timing, Cure And Getting Your Garage Back
Single and double bays generally run over two days: preparation and base coat first, wear layer the following day.
You can usually walk on it after about twenty-four hours and park on it after around five days. We give you the actual numbers for your floor and the weather, not a general rule.
Winter installs are normal here. We read the concrete and bring heat in where the number falls short.
