What customers say
Customers overwhelmingly view this paver cleaner as essential for effective maintenance and sealing preparation. Its primary strength is its powerful ability to dissolve stubborn efflorescence, restoring the pavers' natural color quickly. Reviewers consider it a crucial first step for achieving optimal sealant adhesion and a professional finish. While the product is effective, users stress the importance of following safety guidelines, including wearing protective gear and ensuring good ventilation due to its chemical strength. Thorough rinsing and neutralization after use are also strongly recommended to prevent surface damage. Despite a premium price, the consensus is that the superior, reliable results justify the investment for long-term paver preservation.
Know before you buy
Efflorescence is the white, powdery salt deposit that often appears on the surface of concrete pavers. You must remove it before sealing, as the sealer will trap these deposits underneath, creating a cloudy, unattractive finish that is difficult to fix later.
Yes, this is a concentrated solution. Always follow the specific dilution ratios provided on the product label to ensure you achieve the correct strength for effective cleaning without damaging your pavers.
This product is specifically formulated for concrete pavers, slabs, and interlocking pavers. It is not recommended for use on natural stone, as the acidic nature of the cleaner may etch or damage those materials.
No, this cleaner is not pet or child safe. Because it is a powerful chemical cleaner, you should keep children and pets away from the area while you are applying the product and until the surface has been thoroughly rinsed and dried.
One gallon of this concentrate covers up to 200 square feet. Keep in mind that actual coverage can vary depending on the porosity of your pavers and the severity of the efflorescence you are trying to remove.
No, this is a preparatory step. While it cleans and brightens the surface, it does not provide long-term protection; you should follow up with a compatible Techniseal sealer once the pavers are clean and completely dry to protect your hardscaping.
