- Curing can help concrete be more resistant to damage from freezing and thawing. As long as hydration continues, the cement paste hardens and becomes more dense. If concrete is cured properly, it will be less porous than uncured concrete -- making it more difficult for water and salts to penetrate.

A Discussion on Curing and Sealing Sealing, on the other hand, is a process in which compounds are applied to the surface of hardened concrete to reduce the penetration of contaminants into the concrete placement. Sealers are typically not applied until the concrete placement has had a chance to cure out for 28 days. At 28 days of age the concrete has reached its design strength and characteristically the relative humidity within the concrete matrix is less than 80%.

How to Seal a Concrete Floor Before Applying Vinyl Tile Concrete floors work well with vinyl tiles. Plain concrete is typically a dull grey and useful as a floor material thanks to its hardness and durability rather than its appearance.

A concrete floor should be sealed to protect against moisture, but the sealer can interfere with the tile adhering to the floor. With just a little extra work, you can seal your concrete floor and still make it suitable for vinyl tile.

Xylene and Stamped Concrete The liquid portion of sealer is called the carrier, because it is the means by which the solid particles are “carried” to the concrete surface. In water based acrylic sealers, the carrier is water. In solvent based acrylic sealers, the carrier can be xylene, acetone, or any number of other strong solvents. The solid acrylic particles are what remain on the concrete surface to form a film after the carrier has evaporated.

Concrete Sealer Reviews, Articles, How-To Tips The advantage to sealing new concrete with a cure and seal is that the concrete does not have time to get dirty or stained. If a cure and seal is not being used, then you should allow the concrete to cure for 2-4 weeks. The industry standard is 28 days but that depends on the climate and mix of concrete. It is important to wait and not to seal new concrete too soon. Trapping moisture in the surface will likely lead to a premature failure of the sealer.

Why You Should Seal Your Concrete Patio The right sealer will keep all of the above from penetrating the surface of the concrete and leaving an unsightly stain. A third reason why you should seal your concrete patio is that it will reduce the chance of freeze thaw damage. Freeze thaw damage can cause cracks or surface flaking and is caused by water penetrating the surface of the concrete and then expanding as it freezes. A sealer will keep water from sinking into the patio.

How long should you wait before you seal concrete? Good luck. Typical concrete takes 28 days (4 weeks) to cure. Prior to the 28 days concrete still has moisture in it that weakens the strength of the concrete. If you seal it prior to 28 days there is a chance you will be sealing in some of that moisture and hence weakening the integrity of the concrete.
