The water-based Starseal and solvent-based Ceri-Vex cure and seals use breathable technology that allows moisture vapor to pass though instead of becoming trapped. This prevents whitening, peeling, and flaking. Both are easy to use and non-yellowing, penetrating quickly to form a hard coating that resists wear, chemicals, and stains. Also available is the Concrete Sealer brochure that details all of the company's cure and seals for new and existing concrete surfaces. Vexcon Chemicals Inc., 888-839-2661, www.vexcon.com .
