REASON : When the putty mixture/paste is kept unused for more time and then used again. Whose pot life has been finished already.
SOLUTION : Use of putty paste should be done within 2 hours from mixing with water.
REASON : For gaining maximum coverage, mixing of more water.
SOLUTION : The fixed proportion of water mixing into putty powder should be 1:4. No more water should be added in it.
REASON : Applying of wall putty on walls without moistening wall with water, Hence the dry wall absorb all the water from putty, which results in quick drying of wall putty and hence wall putty gets weaker bonding with wall.
SOLUTION : Whenever putty is to be applied, the wall surface must be moistened with water every time before applying.
REASON : Curing of wall putty surface like cement concrete surface.
SOLUTION : Curing is not required after applying Putty, Just spraying of water 2 times in a day for 2 days will strengthen the hydration of cement particles.
REASON : A painter applies a coat of thickness greater than the normal thickness on smooth surface.
SOLUTION : Coat of wall putty must have a maximum thickness of 2.5 mm only in 2 coat.
