Maintenance & Care

Our hand-crafted concrete tiles are low-maintenance and provide utility and beauty for decades


It is important to keep traffic off the Hartstone during installation. Once installed, cleaned, and sealed, Hartstone is easily maintained with a simple cleaning regimen.

We Recommend

Never using acids or pressure-washers

Using only a soft bristle broom or brush for sweeping and cleansing

Outdoor Clorox for removing mold, mildew, dirt, and most stains

Warm water & Dawn dishwashing detergent for oil and more stubborn stains


Sealing should be completed after installation and cleaning.


We require using Hartstone UP90, which was intentionally created to perfectly complement Hartstone and will not change the color or sheen of your tiles. Speak with your representative about purchasing Hartstone UP90 and shipping it with your order to ensure the best-performing product.
