Dupont Stonetech

STONETECH® Professional tile and stone care and maintenance products are innovative, easy-to-use solutions to protect and preserve stone against the damaging effects of everyday living. With a complete line of products to protect, clean and transform stone surfaces, LATICRETE® will help ensure the beauty of natural stone and tile countertops, floors, walls and other installations for generations to come.

StoneTech’s solutions for stone and natural tile care come in three categories:

PROTECT:  All natural stone is porous to some degree.  If not properly treated with a protective sealer, stains can occur.  The good news is that once treated with a protective sealer, natural stone, tile, masonry and trout are ready for carefree, everyday use.

CLEAN:  When cleaning natural stone and tile, it’s important to use cleaners specially formulated for those surfaces. Many general purpose cleaners can break down sealers and damage stone surfaces.  StoneTech cleaners are carefully formulated by scientists specifically for stone care.

TRANSFORM:  Beyond protecting and cleaning natural stone, sometimes you want to transform the surface to achieve a desired look.  From color enhancing, polishing, shining or adding a gloss finish – StoneTech’s Transform products meet your needs.

In light of the global spread of COVID-19 (Coronavirus), we wanted to reassure you that we’re still paying close attention to the ever-changing situation. Our primary concern is the safety of our employees, customers, and their families.

We have started accepting appointments at both of our showroom locations. Please call in to schedule your appointment and one of our design consultants will email you our COVID-19 protocols so your meeting can be safe and efficient.

Warehouses are open for both material sales and order pick ups. We ask that only one person enter the warehouse at a time to help keep our staff and customers safe.

We are completely CLOSED on Saturday’s while shelter-in-place is in effect.

Together we will get through this. Stay safe and keep creating.
