Finally, acid etching introduces water to the concrete, which is best avoided with many of today's zero V.O.C. and ultra-high solids coatings. Once the substrate is saturated, the contractor must then decide to either wait any number of days for the slab to completely dry or choose a moisture tolerant primer that may add cost to the project.
