The minimum uniform thickness for the specific type of hydraulic cement product referenced is 1/4 inch (6 mm).
According to the provided reference regarding a particular Hydraulic Cement Underlayment, specifically a polymer-modified, self-leveling product, it is designed for application in a minimum uniform thickness of 1/4 inch (6 mm).
This type of underlayment serves to create a smooth, level surface over existing subfloors before installing finished flooring materials. The reference notes:
- Product Type: Polymer-modified, self-leveling, hydraulic cement product
- Application: Can be applied as an underlayment.
- Minimum Uniform Thickness: 1/4 inch (6 mm)
While the product has a specified minimum uniform thickness, the reference also indicates it can be feathered at edges to blend with adjacent floor elevations. Feathering means tapering the material down to a very thin edge, though this is typically done at transitions rather than as the general minimum thickness across the entire area.

| Edge Application | Can be feathered at edges to match adjacent floor elevations. |
Understanding Hydraulic Cement Underlayment Thickness
The required thickness for hydraulic cement products can vary depending on the specific product, its intended use (e.g., structural repair, patching, underlayment), and the manufacturer's instructions. However, for the self-leveling underlayment described in the reference, the manufacturer specifies a minimum uniform thickness to ensure proper performance, strength, and leveling capability.
Using less than the recommended minimum thickness for a uniform application might compromise the product's ability to:
- Achieve adequate compressive strength.
- Properly self-level and create a flat surface.
- Provide durable support for the final flooring.
Therefore, adhering to the manufacturer's specifications, such as the 1/4 inch (6 mm) minimum uniform thickness mentioned in the reference, is crucial for a successful application.
