Concrete Sealing Services in Nashville

In some cases. Stamped concrete may have a topical coating or other finish, while previously sealed concrete may have products on the surface that affect how a penetrating sealer can absorb. The existing finish and condition of the concrete need to be evaluated first to determine whether additional prep is needed and whether penetrating concrete sealing is appropriate. 

New concrete requires cure time before a penetrating sealer is applied. The appropriate timing can depend on the concrete, weather conditions and the sealer being used. The Foundation Specialists can evaluate new concrete and determine when it’s ready for sealing without interfering with the curing process. 

The timeline depends on the size and condition of the area being treated, including the surface prep required before sealing. After SealantPro® is applied, it needs about six hours to cure before the treated concrete can return to normal use. Your installer will give you specific instructions based on the conditions and application. 

Unsealed concrete can soak up water, deicing salts, oil and other contaminants. With time, moisture and repeated freeze-thaw cycles can contribute to surface deterioration, including pitting and flaking. Not all unsealed surfaces develop damage, but sealing adds a layer of protection that can help preserve concrete exposed to moisture, weather and salts. 

Concrete sealing costs vary based on the size and condition of the area, the amount of surface preparation required and the type of concrete being sealed. Cracks, uneven slabs or other damage that needs repair before sealing can also add to the total project cost. The Foundation Specialists provides a free inspection and a written estimate based on your concrete. 

How often concrete should be sealed depends mostly on the type of sealer used. Topical sealers rest on the surface and may need to be reapplied as they wear, while penetrating sealers typically offer longer-lasting protection from inside the concrete. Weather exposure, traffic and the condition of the surface also influence when resealing is needed. 

Yes. Concrete driveway sealing is often a worthwhile way to protect against water, deicing salts and other contaminants, and the same protection can be applied to patios, sidewalks and other concrete surfaces. A penetrating sealer helps limit what porous concrete can absorb, limiting the conditions that lead to staining, pitting and flaking. It’s most effective as preventive protection, not as a repair for existing damage.
