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.

CTD has created a thoughtful process to keep both our customers and employees safe and to keep your visit productive. To help follow all recommended social distancing guidelines and keep the showroom from overcrowding we ask all customers to pre-schedule an appointment with a salesperson before coming in. All employees on site will be wearing masks and customers will be required to wear a mask at all times inside our showroom and warehouse.

When you arrive for your appointment you will be directed to a designated work station to help maintain social distancing. All work stations are cleaned between each appointment as well as all high touch surfaces.

Warehouses are open without appointment for both material sales and order pick ups. We do ask you to follow up posted signage regarding COVID protocols while visiting our warehouses.

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.
