Does concrete need to be sealed?
You do not have to use a cure and seal, but
it is important to seal your concrete
. … Sealing your concrete will protect it against damage and deterioration against water absorption and surface abrasion. Sealed concrete is more resistant to: Cracking, spalling, and pitting.
Is it better to spray or roll concrete sealer?
“
Certain sealers are better applied by spray because they are not formulated for rolling
,” says Dean Owen, president of Arizona Polymer Flooring Inc. in Glendale, Ariz. “This is usually a function of the solvents used in the formulation. Slow-evaporating solvents are better for rolling.
How often should concrete be sealed?
As a general rule of thumb, you should seal your driveway
every one to three years

Do concrete sealers work?
Today, high quality concrete sealers
can block up to 99% of surface moisture
. … The chemical reaction bonds active ingredients within the substrate blocking surface moisture. Penetrating sealers generally do not significantly modify substrate appearance or traction. Lifespan is generally 5 years or more.
How long do you have to stay off concrete after sealing?
Typically, it can take anywhere from 10-12 hours to dry before being able to be walked on, but they will continue to harden for up to 48 hours after being applied. Concrete sealed with an epoxy coating should not be walked on (with the exception of a recoat), driven on, or wet for
at least 36-48 hours
.
How long does concrete sealer last?
Reactive penetrating sealers are the longest lasting concrete sealers, wearing away only if the substrate surface itself wears away. These can last
up to 25 years in
some cases, but we recommend re-sealing concrete driveways every 5-10 years.

Keeping concrete moist helps the curing process
. … If too much water is lost from the concrete through evaporation, the hardening process slows down or ceases. Concrete continues to gain strength after pouring for as long as it retains moisture, but the longer it moist-cures, the slower the rate of strength gain.
Is all concrete sealed?
Most people generally
seal concrete that’s flat
. Things like patios, sidewalks and walkways. A concrete foundation is generally not sealed. Although a concrete wall does get wet, water doesn’t pool on it like it does on flat work so it doesn’t need sealing as much.
