We're Committed to Sustainability.



Green is nothing new for Stonhard. For over 30 years, Stonhard has been an innovator in 100% solids.

Since June of 2005, through recycling efforts, Stonhard has prevented 92.7% of all returned material, including discontinued and obsolete products from going into the waste stream. Stonhard's unique packaging prevents over 4.8 million one gallon pails and quart cans from being dumped into landfills annually.

For over 10 years, Stonhard's Maple Shade, NJ manufacturing facility has not discharged process wastewater to the local municipal sewer system.

Due to the health hazards associated with lead and chromium compounds, the lead sulfochromate based yellow pigment has been removed from the production process of our Epoplex line striping paints.


Stonhard has eliminated the use of chromic oxide (a chromium compound) as a green pigment in several Stonhard aggregate products, which has made these products environmentally friendly (non-hazardous).


Over 90% of new product development and reformulation efforts for the past several years have been geared to water based urethanes or 100% solid epoxy based chemistry. This effort not only provides safer floor and coating products to both industrial and commercial markets, it also reduces hazardous waste.
