Xypex Concentrate DS-1, DS-2Xypex Concentrate DS-1 and DS-2 is a special formulation designed specifically for a dry-shake application on horizontal concrete surfaces where greater resistance to impact and abrasion is required. Packaged in the form of a dry powder compound, Concentrate DS-1 and DS-2 consists of portland cement, various active proprietary chemicals, and a synthetic aggregate hardener which has been crushed and graded to particle sizes suitable for concrete floors. DS-1 and DS-2 becomes an integral part of the concrete surface thereby eliminating problems normally associated with coatings (e.g. scaling, dusting, flaking and delamination). The active chemicals react with the moisture of the fresh concrete causing a catalytic reaction which generates a non-soluble crystalline formation within the pores and capillary tracts of the concrete.
Installing Dryshake
The dry shake application method involves the "spreading" of the Xypex powder by hand or by mechanical spreader onto fresh concrete prior to finishing.
1. Fresh concrete is placed, consolidated and levelled.
2. Wait until concrete can be walked on leaving an indentation of 1/4 in. - 3/8 in. (6.5 mm - 9.5 mm). Concrete should be free of bleed water and be able to support the weight of a power trowel. Then, float open the surface.
3. Immediately after floating open the surface, apply one-half of the dry shake material by a hand or mechanical spreader. The dry shake material must be spread evenly.
4. As soon as the dry shake material has absorbed moisture from the base slab, it should be power floated into the surface.
5. When concrete has hardened sufficiently, power trowel surface to the required finish.
