Ashford Formula, a concrete sealing option manufactured by Curecrete Chemical Company, is a water-based sodium silicate sealer. The formula is the only concrete sealer offering by Curecrete Chemical, making it a highly specialized option.

The solution is clear and odorless with a low-VOC content that makes it legal for use in states like California, New York, Pennsylvania, and New Jersey with strict environmental regulations. More and more states are beginning to adopt such regulations, making it likely that water-based sealers will be the application method of the future. That being said, solvent-based sealers certainly have their place, though adequate care must be taken on application.

As the Ashford Formula is water-based, it can be applied indoors as well as outdoors. Being a silicate sealer, the solution will penetrate through the surface pores of your concrete into the material. Once inside, the silicate particles will react chemical with the free lime and alkalis within the concrete, helping to densify the concrete while protecting it from moisture and water damage, as well as from the passage of harmful natural gases like radon and methane.

While most silicate sealers can be applied to any appropriate concrete surface without an issue, the Ashford Formula is designed specifically for floor use, and isn’t as well known for its use on walls. If you have basement walls that need attention, you’d be better off finding a company with a more extensive product line that offers some more flexible sealers.
