Jennifer's Mosaics Outdoor Cement touts a "super strong formula" that stands up to the harshest of weather. With "crack reduction" (who wouldn't want crack reduction?), the result is a smooth, porcelain white finish. Use colorants and/or grout if you want a more interesting surface. Takes pigments very well. No sealant needed. Each box contains about 13 cups of cement. Minimum dry time of 5 hours for smaller molds up to overnight for largest molds.
