Why Interior Paint Choice Matters
The interior paint you choose defines the look, feel, and durability of your home for the next 5-10 years. In Kolkata's humid climate, choosing the right interior paint is not just about aesthetics — it's about protecting your walls from moisture, fungal growth, and everyday wear. Whether you are painting a new flat in New Town or renovating an old house in north Kolkata, understanding paint types, finishes, and application methods will save you thousands of rupees and years of headaches. This guide covers everything from basic emulsion types to premium luxury finishes available at our interior paint collection.
Types of Interior Paints in India
Distemper: The most basic and cheapest option at Rs. 80-150 per litre. Water-based, gives a flat matte finish. Not washable, not recommended for modern homes. Suitable only for temporary or very low-budget applications. Does not resist moisture or fungal growth.
Acrylic Emulsion (Economy): The most popular category in India. Products like Asian Paints Tractor Emulsion and Berger Bison offer smooth finishes at Rs. 150-300 per litre. They provide decent coverage (120-140 sq.ft./L per coat), basic washability, and come in 1800+ shades. Best for budget-conscious homeowners who want a presentable finish without spending on premium products.
Acrylic Emulsion (Mid-Range): Products like Asian Paints Ace and Berger Velvet cost Rs. 300-600 per litre. They offer superior washability, better hide, anti-fungal properties, and smoother application. Ideal for family homes where walls need to withstand daily wear from kids, pets, and regular cleaning.
Luxury Emulsion: Premium products like Royale Matt Luxury Emulsion, Royale Luxury Emulsion, and Berger Easy Clean cost Rs. 600-1500 per litre. These feature Teflon surface protection, anti-fungal additives, special effects (metallic, silk, air-purifying), and can withstand 5000-10000+ scrub cycles. Recommended for homeowners who want the best finish and longest-lasting results.
Choosing the Right Finish
Matte Finish: The most popular choice for Indian homes. Matte finishes hide wall imperfections beautifully, creating a smooth, sophisticated look with no glare. They are ideal for bedrooms, living rooms, and ceilings. However, basic matte paints are harder to clean. Premium matte paints like Royale Matt use Lustrous silica technology that makes them washable despite the matte appearance.
Satin/Eggshell Finish: Offers a subtle sheen between matte and gloss. Easier to clean than matte, making it perfect for hallways, kids' rooms, kitchens, and high-traffic areas. The slight sheen also makes colors appear richer and deeper. Asian Paints Royale Silk and Berger Silk Breathe Easy are popular satin options.
Glossy Finish: High reflection that creates a dramatic, luxurious look. Best for accent walls, doors, and furniture. Not typically used for entire rooms as it highlights every wall imperfection. Royale Glitz offers a metallic glossy finish that is popular for feature walls in Kolkata apartments.
Special Feature Paints
Anti-Viral/Anti-Bacterial: Royale Health Shield uses silver ion technology to kill 99% of viruses and bacteria on the painted surface. Ideal for homes with children, elderly family members, or anyone health-conscious. Recommended for hospitals, clinics, and schools.
Air-Purifying: Royale Atmos absorbs formaldehyde and VOCs from the air, actively improving indoor air quality. In a polluted city like Kolkata, this is particularly valuable for families with respiratory concerns or young children.
Anti-Fungal: Almost all mid-range and premium interior paints include anti-fungal additives. In Kolkata's monsoon season, this is essential to prevent black spots and peeling on walls, especially in bathrooms, kitchens, and north-facing rooms.
How Much Paint Do You Need?
Most interior emulsions cover 100-140 sq.ft. per litre per coat. For a standard 12x10 ft room with 10 ft ceiling height: Wall area = 2 x (12+10) x 10 = 440 sq.ft. Subtract door (21 sq.ft.) and window (10 sq.ft.) = 409 sq.ft. For 2 coats at 120 sq.ft./L coverage = 409/120 x 2 = 6.8 litres. Always purchase 10-15% extra for touch-ups and wastage.

Step-by-Step Application Guide
Surface Preparation: New plaster must cure for 28 days minimum. Scrape any loose material. Fill cracks with acrylic putty. Sand the surface smooth. Apply primer — this is non-negotiable for new walls as it prevents alkali attack and ensures paint adhesion. Without primer, even the most expensive paint will peel within months.
Priming: Apply one coat of water-based primer like Asian Paints Decoprime or Berger Primer. For new plaster, use an alkali-resistant primer. Drying time is typically 4-6 hours.
Painting: Apply 2 coats of emulsion with 4-6 hours between coats. Use a roller for large areas and a brush for edges (cutting-in). For best results, dilute as per manufacturer instructions — typically 10-20% water for first coat, 5-10% for second coat. Use Royale Matt for bedrooms and Ace for budget areas.
