Check
before painting a metal roof
Most
people know about galvanic action, the corrosive effect
that occurs when incompatible metals come into contact.
But few people are aware of the damage to galvanised iron
gutters and downpipes that can occur when an old roof is
replaced with Zincalume, glazed tiles or painted metal
sheeting. These materials, unlike roofing of galvanised
steel, unglazed tiles or fibro, do not deposit metal salts
and minerals as a protective coating on the inside of the
gutter. Pure rainwater flowing from a chemically-inert
roof may wash away the protective film on the inside of
the galvanised guttering, causing rapid early gutter
failure.

Painting tips & tricks of
the day
Shaking paint: inescapable...
When you buy paint, your retailer is always careful to mix
it in an agitator. Old paint must also be shaken after the
dried surface layer has been removed. The best "tool" to
shake your old paint: a kitchen whip. Otherwise, any type of
handle will do to stir in a figure 8, for a few minutes.
How
much paint to buy
When it comes to calculating how many litres of paint to
buy, remember that one gallon (3.78 litres) will generally
cover 400 square feet. You can calculate the painted surface
in square measure by multiplying depth by the width for
ceilings and the height by the width for walls.
Acoustic
Ceiling Cleaning
Acoustical tile ceilings act as "sponges" for sound, soaking
up excess noise to create a more pleasant environment.
Unfortunately, these tiles also absorb airborne dirt,
grease, cigarette smoke, nicotine, and bacteria, making
ceilings dirty. Professional cleaning solution can break
down the dirt film into micro-dust particles that evaporate
into the atmosphere and are filtered away through the air
handling system.
Paint without removing fixtures
To avoid having to remove fixtures before painting,
particularly when the pieces are difficult to get off,
nothing works like Vaseline petroleum jelly. Just spread it
on the surfaces to be protected before starting to paint and
when finished, clean the fixtures with a paper towel or a
soft cloth. |
