A transparent, non-yellowing, polymer-clay, concrete sealer and methods for making and applying the same. The disclosed clay-based sealer provides a tough, ultraviolet-light-, temperature-, and abrasion-resistant layer that effectively protects surfaces from moisture penetration, staining, dirt, dust, and wear. The substrates to which the clay-based sealer may be applied include, but are not limited to, above and below grade concrete structures, brick, concrete masonry unit (CMU) block, grout, plaster, gunite, tile, and aggregate. The clay-based sealer may easily be applied with airless or air-assisted sprayers, or by roller, brush, or applicator pad. Once applied, the sealer requires minimal maintenance. |

1. A sealer system for sealing exposed concrete, brick, concrete masonry unit block, grout, plaster, gunite, tile, and aggregate, said sealer system comprising:
90 percent by weight to 99.5 percent by weight of a solvent-borne or waterborne polymeric emulsion, a solvent-borne or waterborne polymeric dispersion, a solvent-borne or waterborne polymeric suspension, or solvent-borne polymeric solution; and 0.5 percent by weight to 10 percent by weight of a completely or predominantly exfoliated clay. |
