Yeh galti bahut aam hai — aur main bahut baar dekh chuka hoon. Koi hardware store se ek hi paint khareed leta hai, ghar ke andar bhi lagate hain bahar bhi. 6 mahine mein bahari wall ka paint ukhad jaata hai, ya andar ki wall pe damp smell aane lagti hai.

Yeh dono situations ek hi wajah se hoti hain — galat jagah galat paint. Interior aur exterior paint mein fark hota hai, aur yeh fark samajhna zaroori hai.

Interior Paint Alag Kyun Hota Hai?

Andar ki walls ke liye paint mein kuch khaas cheezein hoti hain. VOC (Volatile Organic Compounds) kam hota hai — taaki smell kam ho aur breathe karna safe ho. Surface smooth hoti hai taaki saaf karna aasaan ho. Zyada scrub-resistant hota hai — kitchen aur bathroom mein faayda karta hai. Sunlight se resist karne ki zaroorat kam hoti hai.

Exterior Paint Mein Kya Hota Hai?

Bahar ki wall pe dhoop, barish, garmi, sardi — sab jhhelna padta hai. Isliye exterior paint mein yeh qualities hoti hain:

• UV resistance — dhoop mein color fade na ho
• Moisture resistance — barish mein bhi kharab na ho
• Flexibility — temperature change se crack na ho
• Fungus/algae resistance — nami wali jagah pe kaala daag na aaye

Agar andar waala paint bahar lagaoge toh 1-2 saal mein ukhad jaayega. Aur bahar waala paint andar lagaoge toh smell bhi aayegi aur surface bhi acchi nahi rahegi.

Bihar Ke Liye Kaunsa Brand Accha Hai?

Main personally Asian Paints aur Berger dono ke saath kaam karta hoon. Dono reliable hain. Asian Paints Apex aur Berger WeatherCoat exterior ke liye bahut tested products hain — Bihar ki garmi aur barish dono sehte hain. Interior ke liye Asian Paints Royale ya Berger Silk accha kaam karta hai.

Jo log sirf "sasta chahiye" kehte hain unhe main samjhata hoon ki sasta paint 2 saal mein dobara karwana padta hai. Thoda zyada lagaao, 5-7 saal tension free raho.

Color Select Karne Ka Ek Simple Rule

Interior ke liye — halke rang (off-white, light yellow, light blue) room bada lagte hain. Chhote room mein dark color aur chhota kar deta hai. Exterior ke liye — bahut light color jaldi ganda dikha deta hai Bihar ki dhool mein. Medium shade ya warm tones better rahte hain.
