Concrete Sealing

To help ensure the concrete’s longevity it is critical to have your concrete sealed. Concrete should be sealed as soon as it is cured, in roughly 28 days unless you are going to add an overlay to your new concrete.  Concrete is porous and absorbs any liquid easily. Sealing concrete prevents the two most common forms of damage:

  • freeze-thaw damage that is common in our region (Western Pennsylvania and Eastern Ohio).
  • staining due to oil, salt, and other chemicals that can cause discoloration.

Concrete sealing should be done to any interior and exterior structure that might be affected including:

  • steps
  • driveways
  • porch/patios
  • fireplaces/fire pits
  • garage floors
  • basement floors

Sealing concrete does incur an additional cost, but but it protects your larger investment in your property. The cost of sealing (or resealing) largely depends on the sealant used and the finish desired.

Concrete Sealing options range from invisible clear coatings to urethane coatings which come in a range of colors and finishes.   The type of concrete sealer also depends on what kind of protection you are seeking, e.g.

  • repel water
  • deicing salts
  • household chemicals
  • industrial chemicals
  • oils

Why shouldn’t I just seal/reseal my concrete by myself?

There are two reasons.  First, the best bang for your buck comes from high performance sealers that are best applied by professional because they require special tools and application techniques. Second, if you are adding a sealer to prevent or fix existing damage you should have someone evaluate the concrete to see if there isn’t a bigger problem.
