Plaster Mein Hairline Cracks Kyun Aate Hain? 10 Common Reasons

Ghar ki tameer mein plaster ek intehai ahem marhala hai. Aksar log dekhte hain ke plaster sukhne ke baad us par baareek (hairline) dararein par jaati hain, jo ghar ki khubsurti ko kharab karti hain. Mere apne tajurbe ke mutabiq, plaster mein hairline cracks bohat si wajohat ki bina par aate hain. Sab se pehli baat ye hai ke masala ka ratio (cement aur ret ka tanao) bilkul sahi hona chahiye. Iske alawa, deewar ki 'tara' (curing/paani dena) ka sahi istemal lazmi hai. Plaster karne se pehle deewar ko achi tarah tar karna chahiye aur plaster mukammal hone ke baad bhi kam az kam 3 se 4 din tak achi tarah paani dena chahiye.

Ek aur ahem baat finishing ke waqt ka intekhab hai. Finishing plaster ko us waqt dena chahiye jab masala deewar ke upar laga hua achi condition mein aa jaye. Iska matlab ye hai ke jab aap masale ko hath lagayein to pani masale mein zyada mehsoos na ho aur masala bhi hath ko na chipke; sirf tabhi finishing dene se cracks ke imkanaat khatam ho jate hain. Aayein ab in 10 ahem wajohat par gaur karte hain:

1. Galat Cement aur Ret ka Ratio

Agar masale mein cement ki miqdar bohot zyada ya bohot kam ho, to plaster mein sikrao (shrinkage) paida hota hai, jis se dararein par jati hain. Hamesha engineering standards ke mutabiq ratio rakhein.

2. Pani ki Kami (Curing)

Plaster sukhne ka amal ek chemical reaction hai jise pani ki zaroorat hoti hai. Agar aapne plaster ke baad 3 se 4 din tak sahi tarah paani nahi diya, to plaster jaldi sukh kar phat jayega.

3. Deewar ki Sahi Taraai na karna

Plaster shuru karne se pehle agar eenton ki deewar ko achi tarah tar (wet) nahi kiya gaya, to eentein masale ka pani choos lengi, jisse masala kamzor ho jayega aur cracks ban jayenge.

4. Finishing mein Jaldbazi

Jaisa ke maine pehle zikar kiya, agar aap masale mein pani ki miqdar zyada hone ke bawajood finishing shuru kar denge, to baad mein jab pani evaporate hoga to jagah khali ho jayegi aur hairline cracks zahir honge.

5. Ret mein Mitti ki Miqdar

Agar aapki ret mein mitti ya namak ki milawat zyada hai, to plaster kabhi bhi mazboot nahi hoga. Hamesha saaf aur achi quality ki ret istemal karein.

6. Weather Conditions

Bohat zyada garmi ya tez dhoop mein plaster karne se pani foran sukh jata hai, jis se plaster ko mazboot hone ka waqt nahi milta. Garmiyon mein plaster ko dhoop se bachana zaroori hai.

7. Thickness Control

Agar plaster ki teh (layer) bohot moti ho, to us mein cracks aane ke imkanaat barh jate hain. Agar plaster 1 inch se zyada mota karna ho to use do layers mein karna behtar hota hai.

8. Deewar par Dhool aur Gandagi

Plaster karne se pehle deewar ki satah par lagi dhool, mitti ya tel ke daagh saaf karna zaroori hai. Agar satah gandi hogi to plaster ki pakad (bond) kamzor hogi.

9. Structural Settlement

Kabhi kabhi cracks plaster ki galti nahi balkay building ke structure mein mamooli jhukao ya settlement ki wajah se hote hain. Iske liye 'Mesh' ka istemal (eent aur RCC ke jor par) lazmi hai.

10. Low Quality Cement

Agar cement expiry date ke qareeb ho ya us mein nami (moisture) aa gayi ho, to wo apni binding strength kho deta hai, jis se plaster mein cracks aana fitri baat hai.

Conclusion

Plaster mein hairline cracks se bachne ka behtareen tareeqa yahi hai ke kaam ke doran sabar se kaam liya jaye. Masale ka ratio sahi rakhein, deewar ko puri tarah tar karein, aur finishing mein jaldbazi na karein. Jab masala hath ko na chipke aur pani ki miqdar munasib ho, tabhi trowel (karni) ka istemal karein. In chand asoolon par amal karke aap apne ghar ki deewaron ko mazboot aur cracks se pak bana sakte hain.
