What flooring is recommended for a milk processing hall?

Heavy-duty acid-resistant tiles or a heavy-duty cast-in-situ floor like polyurethane (PU) concrete or epoxy screed are recommended for their durability and hygiene (Table 1).

What are the most important requirements for a dairy floor?

The floor must be impervious, non-toxic, non-slip, durable, easy to clean, and resistant to lactic acid, cleaning chemicals, and thermal shock from hot water or steam (Clause 3).

What is the recommended slope for a dairy floor?

A minimum slope of 1 in 80 is recommended to ensure effective drainage of liquids, preventing ponding and bacterial growth (Clause 3.1.2).

This standard provides recommendations for the selection of suitable floor finishes for different areas within a dairy plant. It covers essential performance requirements like imperмеability, hygiene, slip resistance, and resistance to chemicals and thermal shock. The code guides users in choosing appropriate materials like tiles, stone, or resinous systems for specific zones such as milk processing halls, cold storage, and laboratories.

Minimum curing period for concrete sub-floor28 days

Practical Notes

Proper surface preparation of the concrete sub-base is critical for the long-term performance of any floor finish, especially resinous coatings.

Joint design and sealing are common failure points. Using appropriate chemical-resistant, flexible sealants is essential to prevent contamination and corrosion.

Consider the entire cleaning regimen, including hot water, steam, and chemical agents (acids/alkalis), when selecting a floor, not just resistance to milk products.
