Did you know that your driveway and sidewalk can sustain serious damage in the winter? As the snow melts or when it rains, it goes inside the pores of your concrete. When the temperature hits freezing point ( 0 degrees Celsius ) the water already lodged inside the pores of the concrete freezes, expanding the concrete by about 9% more. The expansion in the concrete then causes cracking.
How do you protect your concrete during winter?
To protect your driveway and sidewalks the best thing you can do is to get them ready for the winter. How? Before winter begins, check your sidewalks and driveways for cracks, once identified, fix the cracks and splits in your sidewalk and driveway. You can do this by:
1.Calling a concrete company to do the job for you.
Most concrete companies offer crack repairs and concrete grinding. Concrete grinding is when they fix the sloping in the sidewalk that is normally caused by tree roots. Companies that offer crack repairs are like Dry shield.ca
and Crack Buster
. Companies in Canada may charge anywhere between $850
, depending on the extent of work needed.
2.Avoid the heavy cost by simple applying a concrete sealer before the winter on your own.
There are two main types of concrete sealers. They are film-forming sealers and penetrating sealers.
Film-forming sealers are like acrylics, epoxies, and urethanes. These create a coating on the surface of the concrete. Film-forming sealers like acrylics are susceptible to damage and will need to be reapplied frequently.
Penetrating sealers are made with silane & siloxane, they go deep into the surface of the concrete or masonry where it expands and fills the pores in the concrete. They reduce water absorption into the concrete by at least 95%. These sealers do not leave a visible surface film and won’t change the look of your concrete, thus giving your concrete a natural finishing. They will not make your concrete slippery either.
A general rule for penetrating concrete sealers is that the concrete must be cured for at least 28 days before you can apply the sealer. However, there are some brands that can be applied to the concrete less than 28 days old.
Applying concrete Sealer yourself
Things you will need:
- Etching solution ( etching is the process of applying hydrochloric/ muriatic or buffered phosphoric acid to a slab, then rinsing it off with water.)
Things to know
- Most sealers cannot be applied to damp concrete as they will not stick well.
- The ideal temperature for applying concrete sealers is above 50°F during application and for at least 24 hrs after application.
Protect yourself using a mask or face guard and Gloves. (use an apron for your clothes).
Sweep, wash or scrub to remove all oil, grease, stains, dirt and dust from concrete. You have to start with a clean surface to ensure the concrete sealant sticks properly.
Open the concrete with an etching solution. ( you can find this at amazon.ca for as low as $10.99.
- Applying a thin coat of sealer using a roller or sprayer.
- Wait for your sealer to dry. ( Even though your concrete may look dry, sealers will take up to 24 hours to be fully dry.)
- Apply a second coat to the ground in a different direction.
- Allow the sealer to fully dry before you walk or drive on it.
