Maintenance and Diagnostics
Regular inspection and carrying out re-painting work can maintain a painted facade in good conditions.
Diagnostics of Defect
Visual assessment
If peeling affects a large area, it is easily detectable and requires immediate repair.
Pull-off test
Adhesive strengths of the paint film on the surfaces can also be determined to understand whether it is also one of the contributing factor to Peeling and flaking. This is done by carrying out a Pull-Off Test.
Hardness test
Hardness Paint Test can be carried out to determine the compatibility of the paint with the substrate to reduce the problem of peeling.
Thermography
Thermography can be used to determine the presence of any moisture beneath the paint film that cause peeling.
Environment Paint Test
Another method is to carry out a Environmental Paint Test to to determine the amount of moisture content present i.e. whether the paint easily absorb water.
Moisture Meter
Moisture meter can be used to indicate the amount of water present.
