Result WhatsApp par contractor ko seedha bheja ja sakta hai.
Short answer: Sink/bathroom/balcony jaise geele zone ke liye BWP (IS 710); kitchen ke overhead/general cabinet ke liye BWR (IS 303); bedroom wardrobe, TV unit jaise sookhe zone ke liye MR (IS 303). Hinge/screw wali jagah 18mm se kam mat lo.

FAQ
MR, BWR aur BWP plywood mein kya farak hai?
Teeno alag glue se bante hain. MR (Moisture Resistant, IS 303) mein sasta UF glue hota hai — sirf dry jagah ke liye. BWR (Boiling Water Resistant, IS 303) mein PF glue hota hai — humidity jhel leta hai. BWP (Boiling Waterproof, IS 710) mein pure phenol-formaldehyde glue hota hai — sirf yeh genuinely waterproof hai, seedha paani wali jagah ke liye.
Kya saara 'marine' ya 'waterproof' plywood asli hota hai?
Nahi. India mein "waterproof" bol ke MR ya BWR bech dena bahut common hai. Sirf IS 710 code wala BWP genuinely waterproof hai. Hamesha ISI mark ke saath CM/L number check karo BIS Care app par — tabhi confirm hota hai.
Kitchen mein kaunsa grade lagana chahiye?
Sink/base cabinet ke paas — jahan seedha paani lagta hai — BWP (IS 710) chahiye. Overhead ya general kitchen cabinet jahan seedha paani nahi lagta, wahan BWR (IS 303) kaafi hai.
Fake plywood kaise pehchane?
ISI mark ke saath likha CM/L number BIS Care app mein daal ke verify karo — record na mile toh fake hai. Glue-line ka rang bhi dekho — BWR/BWP mein gehra (dark) hona chahiye, MR mein halka. Bahut sasti keemat par "BWP/Marine" bikta dikhe toh red flag samjho.
Plywood ki thickness kaise choose karein?
Carcass (side/back/structure) aur shutter (door) ke liye 18mm chahiye — jahan hinges/screw lagte hain wahan kam thickness se screw nikal jaata hai. Normal shelf ke liye bhi 18mm behtar hai — 12mm sirf halke backing/drawer-base jaisi jagah ke liye hai, structural load ke liye nahi. Back panel/drawer bottom ke liye 6mm chalta hai.
Plywood aur MDF mein kya farak hai?
Plywood patli veneer sheets ko layer mein chipka ke banta hai. MDF lakdi ke fibre ko dabaake banta hai — smooth surface deta hai (paint/CNC ke liye achha) par screw-hold plywood se kamzor hota hai, khaas kar edges par.
Sasta MR plywood kitchen mein chalega kya?
Sirf dry, general area mein. Sink ke paas ya wet zone mein MR lagane se 1-2 monsoon mein hi edge swelling aur delamination ho jaata hai — yeh sabse common galti hai.
'Commercial Plywood' kya hota hai?
Yeh koi brand ka naam nahi hai — "Commercial Plywood" industry mein MR grade (IS 303) ko hi bola jaata hai. Log ise alag category samajh lete hain, jabki yeh sirf MR grade ka doosra naam hai.
