1. How is Xypex DS-2 different from Xypex DS-1?
Xypex DS-2 has been specially designed for dry shake applications on horizontal concrete slabs where greater resistance to abrasion is required. Xypex DS-2 contains the same crystalline waterproofing properties as DS-1, however it also includes a synthetic aggregate hardener which has been crushed and graded to particle sizes suitable for concrete floors.
2. What is the advantage of using the dry shake method?
Because Xypex “dry shake” products become an integral part of the concrete surface, problems often associated with coatings (e.g. scaling, dusting, flaking, delamination) are eliminated. This can be very beneficial for slabs that require a hard surface due to traffic and abrasion. The dry shake method may also provide cost savings, especially on large projects, by reducing material and labor costs and by helping to speed up the construction schedule.
3. When are Xypex Dryshake 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.
