When are Xypex Dry Shake Products (Xypex DS-1 or DS-2) Normally Used?
The Xypex dry shake products are designed specifically for use on horizontal concrete slabs during the new construction phase. By incorporating the dry Xypex powder into the top surface of freshly poured concrete, the active chemicals in Xypex use the bleed water and moisture in the concrete as a migrating medium to generate the crystalline formation throughout the concrete substrate.
