What is the primary use of IS 15194 flooring?

It is used for industrial floors subject to spillage of heavy hydrocarbons like kerosene, diesel, and furnace oil, in places like workshops, refineries, and garages.

What is the specified thickness for this type of flooring?

The recommended thickness is typically between 25 mm and 40 mm, applied in one or two coats as per Clause 8.2.

What is the hardness requirement for the finished mastic floor?

The hardness number at 25°C should be between 10 and 30, as tested by the method in Annex B and specified in Table 2.

Can this flooring be used in food processing areas?

No, this flooring is not suitable for hygienic environments like food processing due to its composition and potential for odour.

Quick Reference Values

Recommended thickness25 mm to 40 mm

Hardness Number at 25°C10 to 30

Binder Content by mass14 to 18 percent

Laying Temperature150°C to 180°C

Resistance to Kerosene (max mass gain)1.0 percent

Softening Point of Pitch Binder (R&B)65°C to 75°C

Practical Notes

Ensure the sub-floor is completely dry, clean, and free of grease before application to prevent blistering and ensure proper adhesion.

Strictly control the laying temperature (150-180°C); overheating can damage the binder and cause excessive fumes, while under-heating makes it difficult to spread and compact.

Adequate ventilation and appropriate personal protective equipment (PPE) are mandatory during application due to the emission of hazardous fumes.
