Note: All data is typical.
Surface Preparation … If the surface of the concrete is clean and free of foreign matter, no further preparation is required. If foreign matter, such as dirt and dust, has accumulated on the surface, it should be removed before applying the compound. If surface moisture has evaporated, as in the case of formed concrete, or the concrete is beginning to dry out, best curing is obtained if the concrete is wetted before application of a 2200-WHITE series product. NOTE: The concrete surface should be moist, but free of standing water. Once the concrete will accept walking workmen without marring, the surface is ready for the application of any 2200-WHITE series product.
Mixing … Any settling in the drums can be re-dispersed with gentle agitation prior to use. CAUTION: TO AVOID FOAMING, DO NOT MIXEXCESSIVELY.
Application Method … Apply curing compound to the surface of the concrete with spray equipment, such as a Chapin 1949 with 0.5 GPM spray nozzle, as soon as possible after the moisture has left the surface. Spray equipment should be capable of spraying a smooth, uniform coat.
Workmen should not track across freshly poured concrete until after the concrete is coated with the curing compound and the film has dried thoroughly.
Drying Time … The product dries in approximately one hour. Restrict foot traffic for at least four hours.
Cleanup … Clean equipment promptly with mineral spirits or other suitable petroleum distillate.
Keep from freezing. Do not apply on interior surfaces. Do not apply when the temperature of the concrete is less than 40° F. DO NOT MIX WATER-BASED COMPOUNDS WITH ANY COMPOUND CONTAINING SOLVENT. SEPARATION WILL OCCUR.
In areas in the South Coast Air Quality Management District in California, the product is for use on roadways and bridges only. (Not for use on curbs and gutters, sidewalks, islands, driveways, and other miscellaneous concrete areas.)
