🔍 Paint Comparisons: Which One Is Right For You?

🎨 Acrylic vs Emulsion Paint

Acrylic Paint: Water-based, quick drying, UV resistant, ideal for exterior walls. Emulsion Paint: Interior wall paint, smooth finish, washable, available in matt, satin, and gloss. For your 3028 sq.ft project, emulsion is recommended for interior rooms (bedroom, hall, kitchen) while acrylic exterior paint is best for otla and open passages.

✨ Matte vs Satin Finish

Matt Finish: Non-reflective, hides wall imperfections, gives elegant look. Best for bedrooms and living rooms. Satin Finish: Soft sheen, easy to clean, durable. Best for kitchen, bathroom, and kids' rooms. Your calculator allows you to choose either finish.

💧 Water Based vs Solvent Based Paint

Water Based Paint: Low VOC, less odor, quick drying time (4-6 hours), easy cleanup. Solvent Based (Oil Based): More durable, better adhesion, longer drying time (12-24 hours), strong odor. For interior walls, water based emulsion is recommended. For exterior, solvent based is more weatherproof.

🧴 Primer vs Putty - Which First?

Correct order on new walls: ① Wall Putty (2 coats) → ② Primer (1 coat) → ③ Paint (2-3 coats). Putty smooths the surface, primer seals and provides adhesion. Never apply primer directly on rough plaster without putty.

🖼️ Paint vs Wallpaper

Paint: Cheaper, easier to apply and repair, lasts 5-7 years. Wallpaper: More expensive, difficult to install, lasts 10-15 years but hard to remove. For most homes, paint is more practical and cost effective at ₹15-25 per sq.ft vs wallpaper at ₹50-150 per sq.ft.

👑 Luxury Paint vs Regular Paint

Luxury Paint (e.g., Royale, Velvet Touch): Superior finish, anti-bacterial, stain resistant, rich texture. Cost: ₹300-500/liter. Regular Paint (e.g., Tractor Emulsion, Economy): Standard finish, good coverage. Cost: ₹150-250/liter. For your 3028 sq.ft, luxury paint would cost ~₹1.5 lakh more than regular paint.

❓ Frequently Asked Questions About Paint

1. Which paint is best for interior walls?

For interior walls, emulsion paint is best. It offers smooth finish, washability, and durability. Within emulsion, choose matt finish for bedrooms and satin finish for kitchen/bathrooms. For your 3028 sq.ft project, premium emulsion like Asian Paints Royale or Berger Silk Glamour is recommended.

2. What is the cheapest paint for home?

The cheapest paint for home is distemper paint (₹80-120/liter) or economy emulsion (₹150-180/liter). For a 3028 sq.ft area, distemper would cost ~₹25,000 while premium emulsion costs ~₹1,10,000. Economy emulsion is the best value at ~₹55,000.

3. Paint or putty first on new wall?

Putty first, then primer, then paint. Never apply paint directly on plaster. Wall putty fills pores and creates a smooth base. After putty dries (24 hours), apply primer. After primer dries (6 hours), apply paint.

4. Is primer necessary before painting?

Yes, primer is necessary. Primer seals the putty/plaster surface, reduces paint absorption, provides uniform finish, and increases paint life. Skipping primer can increase paint consumption by 20-30% and cause uneven finish.

5. How long does paint last on walls?

Good quality interior emulsion paint lasts 5-7 years before needing repainting. Exterior paint lasts 3-5 years due to weather exposure. Premium luxury paints can last up to 10 years with proper maintenance.

6. Can I paint over old paint?

Yes, but surface preparation is key. Clean the wall, repair cracks, sand lightly if glossy, then apply primer before new paint. If old paint is peeling, remove it completely first.

7. What is paint drying time between coats?

Water-based emulsion: 4-6 hours between coats. Oil-based paint: 12-24 hours. Primer: 4-6 hours before paint. Your calculator default uses 6 hours drying time for emulsion paint.

8. How to calculate paint cost per square foot?

Paint cost per sq.ft = (Paint price per liter ÷ Coverage sq.ft per liter) + (Primer cost ÷ Coverage) + (Putty cost ÷ Coverage). For standard emulsion: Paint ₹220/110 sq.ft = ₹2/sq.ft + Primer ₹150/130 = ₹1.15/sq.ft + Putty ₹25/5 = ₹5/sq.ft → Total ≈ ₹8-10 per sq.ft for materials only. Your calculator shows exact cost.

9. What is the difference between acrylic and emulsion paint?

Acrylic paint is water-based with acrylic resin - best for exterior walls, UV resistant, durable. Emulsion paint is also water-based but formulated for interior walls - smoother finish, washable. For your project, use emulsion inside rooms and acrylic on exterior otla/passage.

10. What paint colors are best for home?

Popular paint colors for home: Bedroom: Light blue, lavender, beige. Living room: Off-white, cream, light grey. Kitchen: Yellow, light green, white. Kids room: Pastel pink, mint green, peach. Always use light colors for small rooms to make them appear larger.

11. Wall putty vs primer - what's the difference?

Wall Putty: Cement or acrylic-based paste applied on plaster to fill pores and create smooth surface. Applied 2 coats. Primer: Liquid applied over putty to seal surface and provide adhesion for paint. Both are essential - putty for smoothness, primer for paint bonding.

12. What are the coverage rates recommended by IS codes?

As per IS 15489 and Indian paint standards: Wall putty (2 coats) = 4-6 sq.ft/kg, Primer (1 coat) = 120-140 sq.ft/liter, Emulsion paint (2 coats) = 100-120 sq.ft/liter. Our calculator uses these BIS-recommended ranges.

📋 Standard Paint Coverage Reference (As per IS norms)

Material	Coverage (sq.ft/liter or kg)	For 3028 sq.ft (Your Project)
Wall Putty (2 coats)	5 sq.ft per kg	606 kg
Primer (1 coat)	130 sq.ft per liter	23.3 liters
Emulsion Paint (2 coats)	110 sq.ft per liter	55 liters
Texture Paint (2 coats)	40 sq.ft per liter	151 liters
Exterior Paint (2 coats)	90 sq.ft per liter	67 liters

💡 Pro Tip: Always buy 5-10% extra material for wastage and touch-ups. Your calculated quantities should be multiplied by 1.05 for safety.
