Walls
and ceilings are subject to cracks, usually
soon after construction, sometimes much
later. Much of the earlier cracking is
superficial, easily remedied and quite
unlikely to recur. You may now breathe
a sigh of relief.
If cracks are noticed on the wall, (generally
fine ones- check by pushing a paper through
the crack. If the paper does not travel
through and through the wall you have
not much to worry. During your next painting
after thorough scraping of old paint and
cleaning of the dust, the painter will
fill up the crack with good quality putty
before applying new primer and paint.)
Building sets in two seasons, surface
cracks do appear during this tenure.
Why do these cracks occur? Diagnosis of
the specific cause is often difficult
to ascertain. Numerous forces come into
play as many building factors may also
contribute (sometimes very generously)
towards the formation of a crack.
Commonly
noticed patterns of cracks are:
Shrinkage cracks: This type is
perhaps the most common and innocuous
form of cracking observed in buildings
due to drying. Thankfully, it can be easily
rectified after a full season of its appearance,
by scraping and painting.
Settling cracks: These usually
make their debut horizontally below a
beam. Higher storeys seems more susceptible
to this type of cracking than lower ones.
The cause is attributed to minor settling
of the building structure, but its appearance
can be very unsettling to the occupants.
Though these cracks are normally not severe,
it is agreeably unsightly and unanimously
unacceptable. This could also be a cause
of leakage for outer walls.
After a year of observation, if the crack
does not show any further signs of lengthening
or widening, it may be safely filled up
with 'Snowfilla' or putty after thorough
cleaning and touched up with the right
shade of paint.
If the crack shows signs of widening or
a new major pattern of cracks develop,
a careful analysis by a competent consultant
is required and his advice sought for
effective remedial measures.
Radiating
cracks: These are the outcome of hammering
nails or hooks in walls made of solid
concrete blocks.
You can avoid cracking the walls by using
hand driven augers or jumping bits. Portable
drills are (the best option) to drill
holes and then plugging them with wetted
'Rawal' plugs to hold the screws.
The Rawal Plugs or grip plugs as
they are sometimes called, will hold the
screws firmly in the wall and also prevent
any development of radiating cracks.
Don't forget to check for concealed electrical
wiring before driving in any screws. It
could be a shocking experience for anyone.
Impact cracks: These can occur
in the neighbourhood of door/ window frames
when the doors and windows are left unsecured
with stays or stoppers and a strong gust
of wind takes an unfair advantage of the
situation. They also occur when heavy
carpentry/ breaking work is done in the
building.
The
impact of shutters against the frames
may not only leave cracks in the neighbouring
walls, but also result in broken window-panels
and loose hinges not discounting the possibility
of serious injuries.
So keep you doors and windows well secured,
whether shut or open.
Radiating and impact cracks can be
easily attended to by:
Cleaning the cracks by a sharp nail to
the full width & depth.
Blowing off the dust and then filling
up with M-Seal or any other suitable sealant/
filler.
Scraping off excess sealant/ filler with
a sharp edge to level it.
Retouching the crack with just the right
shade.
Simple.
Isn't it?
If paint bubbles appear above skirting
or below sill, indicate that the inside
moisture is trying to come out. Drill
holes and allow it to come out. Leave
for month or so and then paint the area
with breathable paint.
Use drill bit, rawal plug and screws instead
of nail and hammer. Screwing is the correct
option.
- use proper drill and rawal plugs.
Clean the walls and ceilings regularly
and do not allow cobwebs to appear.
