DRY SHAKE FLOOR HARDENERS Euclid Chemical

DRY SHAKE FLOOR HARDENERS

General Guidelines:
The following recommendations of ACI 302 and the following topics should be carefully reviewed prior to the pre-slab meeting.

1. “Dry Shake Floor Hardeners” are formulated to be applied to properly designed concrete. Conditions such as high winds, low humidity or hot or cold weather require mix design changes and adjustments in application and/or finishing procedures. In dry conditions, The Euclid Chemical Company recommends the use of EUCOBAR to help retain moisture.

2. A well compacted, leveled sub-grade is required. Follow recommendations of ACI 360, “Design of Slabs on Grade”.

3. Concrete containing calcium chloride or admixtures with > 0.05% chloride ions should not be treated with metallic dry shakes. Air content must be below 3% for all dry shakes.

4. The correct number of bags should be positioned along the sides of the slab placement prior to the start of each days concreting operation.

5. Note: Colored (pigmented) dry shakes require special attention to achieve a uniform color. If the job involves placement of a colored dry shake, the best appearance and performance results from:

  • a. Delaying application of the shake as long as possible to the get the maximum color saturation at the surface of the slab.
  • b. For maximum uniformity, apply the shake in two even passes.
  • c. Do not burnish the final trowel. Hand troweling the final finish results in the best appearance.

IMPORTANT:
If the contractor is not familiar with the standard application techniques of a dry shake floor hardener, a pre-job meeting is suggested to review the project concrete mix design as well as placement and curing details unique to the particular job.
