The Ashford Formula, manufactured by Curecrete Chemical, Inc., was the first product to protect and seal concrete through the process of chemical densification. Unlike coatings or membranes that simply lie on top of the concrete and eventually wear off, the Ashford Formula penetrates the surface of the concrete and reacts chemically with it to produce a dense, harder, more stable surface. Ashford Formula locks in the salts in the concrete and completely eliminates annoying dust. The results are permanent, so no re-treatment is ever required.
The product is commonly specified for use in manufacturing plants, warehouse, exhibit halls, stadiums, retail facilities, and distribution centers. Environmentally friendly, odorless, water-based, nontoxic, and simple to apply. Now available worldwide. Learn more at www.ashfordformula.com.
