A good concrete sealer is not an expense, it’s an investment and over time it can save you a lot of time and money. In today’s post we’ll take a closer look at some the reasons why your concrete needs sealing.
Protect your Concrete from ugly stains
Concrete is a porous material which means it’s full of very tiny pores. It’s like a sponge, except on concrete, you can’t really see the pores. Liquids like oil, grease and even water can easily get into these pores and when they do, they leave stains that are almost impossible to clean because the liquid has soaked into the concrete through the tiny pores.
But spilling things on your concrete driveway or basement or garage floor is not the only way to get ugly stains on your concrete. Moisture from the ground below the concrete will cause salts from within the concrete to come up to the surface leaving your concrete floors looking old, ugly and unhygienic.
A topical sealer or a coating fills in the tiny pores and makes sure these liquids do not get into the concrete. So even if you did get some grease, oil or wine on the concrete floor in your garage, basement or driveway it won’t enter the concrete and leave a stain.
Protect your Concrete from water intrusion
Water is concrete’s worst nightmare. Water and concrete do not mix. And that’s not a theory, extensive research by the concrete authorities in North America have confirmed that almost all damage to concrete is attributable to moisture intrusion which means almost all the damage to your concrete happens because water can get into the concrete from the tiny pores in them.
When there’s water in your concrete and it freezes, it expands by 9%. When salt water freezes, it expands by 18%. This continual expansion and contraction causes internal and topical damage to your concrete. Here in Columbus, Ohio there can be several freeze thaw cycles completed in a single day.
Applying a concrete sealer on your substrate will fill in these tiny pores in your concrete and reduce the amount of water that the concrete absorbs.
Makes your concrete stronger
Using a penetrating sealer for your concrete floor can harden and increase the density of concrete, increasing its strength as measured in pounds per square inch (PSI) and lifespan.
There are two main types of sealers in the market today, Topical Sealers and Penetrating Sealers. Topical sealers generally provide visual enhancement as well as topical protection while Penetrating Sealers provide lifelong protection.
