Factors Affecting Sealer Performance on Concrete

By C. Jim Reader, Evonik Corporation, and Gary Johnson, Intertek Allentown It is often assumed that solvent-based sealers give better performance than water-based formulations on concrete because the solvent-based sealers are thought to better penetrate into the concrete matrix. In practice, it can be difficult to measure actual penetration of a sealer into concrete, as dyes and […]
