You do not have to use a cure and seal, but it is important to seal your concrete. Whether you want to cure in in the first 2-28 days, or wait six months, that is entirely your preference. Sealing your concrete will protect it against damage and deterioration against water absorption and surface abrasion.

What happens when you don't seal concrete?

What happens if I don't seal my concrete? Concrete is a porous material that readily absorbs liquids.

Does sealing concrete make it stronger?

But once time, pressure, and abrasion start to do their work, the damage comes even faster. Cure and seal increase the lifespan and durability of freshly-poured concrete in three specific ways: Maintains moisture within the surface to encourage an even cure. Causes the concrete to achieve full compressive strength.

How long does concrete sealing last?

Acrylic topical coatings have the shortest lifespan, needing re-applied every 1-3 years. Epoxy and urethane systems last between 5-10 years, closer to 5 if the surface experiences heavy traffic.

Is it better to roll or spray concrete sealer?

Should I pressure wash concrete before sealing?

Sealing without cleaning first is a huge mistake that only a novice would make. However, getting out all of the dirt and grime along with stains is a must before permanently securing them onto the driveway's surface with a sealer.

Does sealing concrete make it darker?

Sealers, particularly solvent-based sealers, will darken concrete. If unevenly applied, it will create light areas where there is less sealer, and darker areas where there's more. If applied by sprayer, it may appear like “stripes”. Uneven roller application may leave darkened roller marks.

Does concrete take 100 years to fully cure?

Does concrete take 100 years to cure? No, this is a bit of a myth with the concrete industry. While concrete does continue to harden indefinitely, pore moisture has to drop below a certain level at some point and this isn't typically 100 years.

Do you need 2 coats of concrete sealer?

Concrete sealers are best applied in two thin coats. The first coat of sealer acts like a primer. Most of it will disappear into the concrete surface, and the concrete will probably look fairly unattractive after the first coat. The second thin coat will provide an even finish, color enhancement and gloss.

What is the best temperature to seal concrete?

Most manufacturers recommend 50 to 90 degrees as the ideal temperature range for applying concrete sealer.

What is the cheapest way to seal concrete?
