Concrete Sealing Services in Sioux Falls

Sometimes, yes. Stamped concrete may have a topical coating or other finish, while previously sealed concrete may have residue on the surface that affects how a penetrating sealer can absorb. The existing finish and condition of the concrete should be reviewed first to see whether additional preparation is needed and whether penetrating concrete sealing is appropriate. 

New concrete needs time to cure before a penetrating sealer goes on. Appropriate timing depends on the concrete, weather conditions and the sealer being used. Blackburn Foundation Repair can assess new concrete and determine when it’s ready to be sealed without disrupting the curing process. 

Installation time comes down to the size and condition of the area being treated, including the surface preparation required before sealing. Once SealantPro® goes on, it needs roughly six hours to cure before the treated concrete can return to normal use. Your installer will share specific instructions based on the conditions and application. 

Unsealed concrete can absorb 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 provides an added layer of protection that can help preserve concrete exposed to moisture, weather and salts. 

Concrete sealing prices 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 requiring repair before sealing can also affect the total project cost. Blackburn Foundation Repair provides a free inspection and a written estimate based on your concrete. 

How often concrete should be sealed depends largely on the type of sealer used. Topical sealers sit on the surface and may need reapplication as they wear, while penetrating sealers typically provide longer-lasting protection from within the concrete. Weather exposure, traffic and the condition of the surface can also affect 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, reducing the conditions that contribute to staining, pitting and flaking. It’s most effective as preventive protection rather than a repair for existing damage.
