Kitchen and bathroom walls face conditions unlike any other room: constant moisture from cooking steam and hot showers, temperature fluctuations, grease and oil deposition in kitchens, soap scum and chemical cleaners in bathrooms, and persistent fungal growth from dampness. Standard interior emulsions — even premium ones like Royale Matt — are not designed for these conditions and will develop fungal patches, blister, peel, or discolour within 6-12 months. Choosing the right paint for kitchens and bathrooms is about durability, hygiene, and long-term savings, not just aesthetics.
What Makes Kitchen & Bathroom Paint Different
Moisture Resistance: The paint must form a barrier that prevents water absorption. Without this, paint film absorbs moisture, swells, and eventually detaches from the wall surface. Look for paints specifically labelled for wet areas with moisture-resistant polymer binders that create a hydrophobic surface.
Anti-Fungal Properties: Non-negotiable for bathrooms and kitchens. The paint must contain biocides that prevent mould and mildew growth even in high-humidity conditions. Kolkata's humidity (70-95% during monsoon) makes fungal resistance especially critical. All major brands offer anti-fungal variants specifically for wet areas with proven efficacy.
Washability and Stain Resistance: Kitchen walls get greasy splatters, food stains, and fingerprints. Bathroom walls accumulate soap scum, toothpaste marks, and water stains. The paint must withstand frequent scrubbing — look for Class 1 or Class 2 washability rating per IS 15489 standard. Berger Easy Clean and Asian Paints Scuff-X lead in this category with the ability to withstand 10,000+ scrub cycles.

Surface Preparation for Wet Areas
For Existing Walls: Remove all peeling paint with sandpaper. Treat fungal patches with a dedicated fungicidal solution (not bleach, which damages paint film). Fill cracks and repair damaged plaster. Apply 1 coat of water-based primer, then 2 coats of kitchen/bathroom-specific paint. For walls with recurring dampness, apply a damp-proof primer like Dr. Fixit Primeseal before the regular primer.
For New Construction: Allow plaster to cure for minimum 28 days (35-45 days in Kolkata's humidity). Apply 2 coats of putty and sand smooth. Apply 1 coat of primer. Apply 2 coats of kitchen/bathroom paint. Ensure the bathroom exhaust fan is operational before painting, as proper ventilation significantly extends paint life in wet areas.
