Scaling on concrete is a result of moisture inside the slab expanding and contracting as temperatures fluctuate.
Not only is scaling unsightly, but it can also reduce the lifespan of your concrete.
In this blog post, we’ll explore some tips on how to prevent scaling on your concrete surfaces. By following these tips, you can keep your slabs looking their best for years to come.
1. Seal your concrete
Sealing your concrete before the turn of winter will help reduce its water absorption, and thus minimize the amount of thawing and freezing that occurs. This is a simple, yet vital step and will protect your concrete in more ways than one.
2. Stop using harmful deicing salt
If you live in a colder climate where snowfall is common, it can be tempting to reach for the nearest deicing chemical as soon as temperatures start to drop.
Contrary to popular belief, however, these deicing salts are about as problematic to concrete as water. This is because concrete is made up of calcium hydroxide, and when it interacts with calcium chloride, calcium oxychloride crystals are formed and cause concrete to crumble.
If you must use a deicer, make sure to avoid those with sodium chloride, calcium, and magnesium ingredients. Sand is also a good alternative to traditional deicing salts.
3. Allow the concrete enough time to cure
The stronger your concrete, the less likely it is to fall victim to scaling.
Of course, one of the keys to strong concrete is its cure time.
Taking shortcuts during the curing process due to impatience or incompetence will significantly decrease its strength.
We recommend using a liquid membrane curing compound and covering the wet surface with polyethylene sheets and wet burlap. Then, make sure the concrete temperature stays above 50°F for a week.
