Inferior quality paint on the
building exteriors can lead to moisture seeping in through the porous concrete
and getting collected with a wall. This creates damp patches and further, the
wall paint may start to peel or develop blisters. One can observe this in the
form of dome-shaped bulge under the paint film. In the longer run, this tends
to become a breeding ground for algae and fungus. The choice of exterior paint
is crucial as it protects the external wall by preventing rain water and
moisture from entering the concrete. It should be well-equipped to fight the
vagaries of the weather conditions.
Maintenance tips
- The
exterior wall should be repainted with weather proof paint so that any
damage to it could be avoided.
- A
water sealant, which is a special liquid, should be applied like paint on
the exterior wall as it acts as a protective layer on concrete wall.
- The
walls should also be repainted after applying the sealant to get maximum
protection.
