Dry removal of the old concrete surface is most effec tively accomplished by abrasive blasting to remove the contaminated concrete and weak concrete, while provid ing a textured surface for bonding. Don’t apply grout faster than the overlay concrete can be placed and never let the grout dry to a whitish appearance be fore the overlay concrete is placed. Curing Bonded Overlays Proper curing is even more important in bonded resurfac ing than in ordinary concrete work because of the poten tial for rapid, early drying of the thin concrete overlay due.
