Resealing Concrete

Just like many elements of your property,  concrete needs regular maintenance to look its best and retain its durability.   Resealing concrete is a different process than the initial sealing performed when your concrete wall, sidewalk, patio porch, or driveway was built.   Beware of products or contractors who suggest that one needs to merely reseal your hardscaped areas by adding fresh material.  New sealant must be chemically compatible to adhere to the existing surface.

In addition, a professional concrete contractor should take the time to inspect concrete for settlement, cracking , corrosion, and other common types of concrete damage.  If problems are identified and fixed early, it can literally save thousands of dollars in either concrete repair or concrete replacement.

Preparing Concrete for Resealing.

Sandblasting is an excellent way to thoroughly prepare for concrete resealing

Concrete surfaces that need to be resealed must be prepared properly.  There are three ways to prepare for concrete resealing:

  • chemical solvents to remove existing sealants
  • Applying new sealant and then agitating the sealer to mix with the existing coating.
  • sandblasting

The quality and condition of the original sealant will determine how the new sealant should be applied to the existing structure.  If the concrete sealant is in good condition, it may be possible to apply it and ensure a good seal with agitation as long as the area to be  resealed is handled in small sections.

In addition to resealing concrete, many clients opt to update the concrete by

  • adding colors or finishes
  • adding nonskid additives to flatwork such as patios, walkways, driveways, etc.

The Importance of Regular Maintenance

Resealing should be done every 3-7 years.  Adding new layers of sealant to an existing feature or decorative concrete structure is not always the best solution.  An experienced concrete contractor:

  • can easily perform the work
  • has access to professional grade sealants
  • knows how to handle the chemicals
  • understands environmental constraints such as temperature and humidity
  • will inspect the stamped to identify any other issues that need to be repaired prior to concrete resealing
