What are the common thicknesses for rubber flooring under this code?

Commonly specified thicknesses range from 2.0 mm to 6.0 mm, chosen based on expected foot traffic and load requirements.

How is the hardness of the rubber flooring specified?

Hardness is typically measured in IRHD (International Rubber Hardness Degrees) and should fall between 75 and 85 to ensure adequate wear resistance while providing underfoot comfort.

Which IS code is referred for testing the physical properties of the rubber?

The IS 3400 series (Methods of test for vulcanized rubbers) is heavily cross-referenced for testing tensile strength, hardness, and aging.

IS 809

This standard prescribes the requirements and methods of test for solid rubber flooring materials used for general purposes in buildings. Architects, interior designers, and material engineers use this specification to ensure quality control, durability, and dimensional consistency of rubber flooring sheets or tiles.

Practical Notes

Rubber flooring materials should be acclimatized to the installation room temperature for at least 24-48 hours prior to laying.

Ensure the concrete sub-floor is perfectly smooth, level, dry, and free of dust. Any unevenness will eventually telegraph through the flexible rubber flooring.

Always verify the chemical compatibility of the adhesive with the specific rubber flooring compound to prevent delamination or chemical breakdown over time.
