IS 4971: Important Factors for Selecting Floor Finishes (Clause 5.1 & Table 1)

Selection depends primarily on:

• Durability
• Type and magnitude of load
• Slip resistance and safety
• Resistance to chemical exposure
• User-friendly features
• Visual appeal
• Cost-effectiveness

Excerpt from Summary Table for Different Industrial Facilities

Legend:

• VC = Very Critical
• I = Important
• R = Required
• P = Preferred
• 1 = To some extent
• 0 = Variable

Additional Insights:

• Maintenance (Clause 5.7): Flooring should facilitate easy upkeep and repair to restore original condition.
• Structural Stability Impact: Floor finish performance depends on the structural floor’s soundness; movement or chemical spillages may cause deterioration.

Practical Recommendation:

Select floor finishes prioritizing the most demanding factor (abrasion, chemical resistance, slip resistance) relevant to the industry, balancing durability and cost.

IS 4971: Key Aspects of Cement Concrete and Stone Flooring

1. Plain Cement Concrete Floors (Clause 6.1.1)

• Commonly used in industrial flooring.
• Resistant to mineral oils and greases; gradual degradation by acids, vegetable oils, fats, and sugars.
• Properties (Table 2):

Legend: VG = Very Good, G = Good, P = Poor

2. Bedding and Jointing Materials (Clause 8.1.1 & Table 5)

• Must adhere strongly, resist chemical attack, and endure wear.
• Typical materials include:

• Bedding and jointing materials can differ; chemical-resistant mortars are recommended for joints in aggressive environments.

3. Dairy Floor Recommendations (Table 4)

• High impact zones: Steel tiles in granolithic concrete.
• Wet and chemical-exposed areas: Paving bricks or chemical-resistant resin mortar joints.
• Cold storage: Acid-resistant bricks or tiles with cement mortar bedding and resin mortar joints.

4. Stone Flooring (Clause 6.3)

• Use natural stones with good abrasion and chemical resistance.
• Should be installed on suitable bedding mortar with proper jointing.
