Excellent Tips for Painting
Painting with glasses
If you wear glasses, simply cover the lenses with plastic cling
wrap, and then when you peel it off, all the paint spots go with
it.
Knobs and things
Always remove as much hardware as you can before you paint.
Carefully scrape old paint out of screw slots before you try to
unscrew them.
Paint spills
First, contain the spill from spreading. Scrape up as much paint
as possible, working from the outside of the spill inwards to help
prevent further spreading. Kitty litter can also be used to soak up
paint.
Wet paint on carpet & materials
Most acrylic paints can be washed out of carpet & material
so long as it is attended to immediately & the paint stains are
kept wet. Rinse the affected areas immediately with water, sponge
out & rinse with clean water. Detergent cleaners can also
assist.
(Ensure that no diluted paint run off flows into sewer,
stormwater or any natural waterways.)
Most oil-based paint can be thinned with mineral turps & then
washed out with warm water & detergent, then rinsed with clean
water.
Caution must be taken with the use of thinners & cleaning
products. Do a small discrete test area on the affected material
with the cleaner/thinner to ensure that it will not damage the
material to be cleaned.
For paint spills that have dried
In some situations dry paint can be scraped off with a
razorblade scraper (eg glass & glazed tiles). In most cases
acrylic paint can be softened with methylated spirits which can aid
in removal of the paint. Oil based paints dry harder; mineral turps
may soften them if they have not fully cured. If methylated spirits
or mineral turps do not affect dry paint spills, a paint stripper
may need to be used.

Unmasking
Always remove masking tape before the paint is completely hard
so it won't chip and crack. Removing tape while the paint is still
relatively wet will prevent most problems.
Stop mould
Lack of ventilation and moisture encourages mould growth.
Exhaust fans and Dulux Wash & Wear Kitchen and Bathrooms can
help prevent re-growth.
Clean start
Thorough washing with Selleys Original Sugar Soap will remove
grease and dirt and ensure the best possible performance from the
finish coats.
Mirror finish
For a superior mirror-like finish under gloss paints use
Polyfilla Mirror Finish. It is smooth and easy to apply. It has
excellent adhesion to timber, plaster, concrete, mortar and primed
metal. Mirror Finish comes in two convenient sizes, 425gm and
950gm.
Paint pads
Painting hallways can involve many architraves and skirtings.
It's a good time to think about trying out a paint pad. These
little foam pads with wheels can really speed up the job, taking
the fuss out of edges.
First stop
Paint exterior doors and windows early in the day and prop them
open to dry, and they will be ready to close by
nightfall.
Little things
An artists brush, instead of a house painting brush will help
you pick out small details in extra colours quickly and
neatly.
Time travel
Gently scraping the paintwork can reveal your home's colourful
history and give you some original colour ideas.
Cool tip
If you are using water based paints, on a hot day, spraying
walls with water before you paint will cool them down and make the
job faster and easier - you can even paint them when they are
damp.
Painting over glossy enamels with acrylics
Make sure that the old painted surface is clean and sound. Gloss
enamels should be sanded to a flat finish, before you repaint with
an acrylic. If you are using a flat or low sheen acrylic finish, an
undercoat may not be necessary. If a gloss or semi gloss were to be
used, an acrylic undercoat would be necessary to fill any
imperfections left by the sanding. Lightly sand the undercoat to
give a smooth flat finish.
Checking if your old paint is sound
The best way to find out if your old paint is sound, and ready
to be repainted, is to test the paint in several areas by cutting a
small cross with a sharp knife and press 10cm or so of adhesive
tape firmly across the middle of the cut. Rip it away quickly after
a few minutes and if any pieces of paint come with it you'll need
to strip away the loose paint. If the paintwork has failed the
adhesion test or is heavily layered, it should be stripped back to
a firm clean base before repainting.
Using Dulux topcoats and preparation products
You should always use Dulux topcoats in conjunction with Dulux
preparation products. Manufacturers make their paints to work
together. We have no control over the products of other
manufacturers, so mixing brands will void any warranties.
Yellowing
All oil based paints share the problem of yellowing. White oil
based paints in particular are more noticeable.
Yellowing is caused during the ageing process and it is
particularly prevalent where enamels dry in the dark, in high
humidity or if there is poor air circulation. A good example of
yellowing is where a sliding door is left in the cavity - it will
yellow if it is not exposed to sunlight. Yellowing may be evident
sooner if enamels are allowed to dry in the same area where most
water based paints are drying. Ideally you should allow 2-3 days
for water-based paints to dry before painting enamels in the same
area. The only way to be sure that your white painted surfaces
won't yellow is to use an acrylic (water-based) paint.
Painting kitchen cupboards
Laminex® and Formica® are brand names of products commonly used
in kitchen benches and cupboards. Dulux PrepLock Shellac Base is a
rapid drying preparation paint which is perfect for painting
ceramic tiles and melamine without the need to sand first. Dulux
recommend PrepLock and a top coat of either Dulux Aquanamel or
Dulux Super Enamel for cupboard surfaces. We do not recommend
painting of work surfaces such as bench tops.
Painting gutters and fascias
The best product for these areas would be Dulux Weathershield
Gloss.
Painting decks
Dulux recommends Dulux Weathershield Low Sheen for decks. If you
require a timber oil or stain we recommend Cabot's decking oil or
stain. Visit the Cabot's website at
www.cabots.com.au.
When droplets appear on acrylic paint
Don't panic! Sometimes, when acrylic paints are drying, small
light coloured droplets will appear on the surface. This usually
happens if newly painted surfaces are exposed to moisture, either
by dew, high humidity, or rain on the outside, or steam etc. on the
inside. These droplets cause no downgrading of the paint film's
durability. They only affect the appearance. Wash the surface with
sugar soap, and then rinse with plenty of water. Sometimes droplets
may continue to appear for a time and will need wiping down until
they stop. These droplets are a surfactant, which is drawn to the
surface by moisture.
Longevity of paint in storage
How long paint lasts in the can depends on how well it was
stored. Paint lasts the longest time when the can is full, well
sealed and has been stored in a cool dry place (not a damp garden
shed!) Some paint types will last longer than others.
To check an old can of paint, open it, stir it well and apply it
to a test area. Does it smell like paint? Is the consistency of the
paint neither too thick nor too thin (like single cream)? Does the
test area dry in the time indicated on the can? If the answer is
yes to these questions, then your paint is probably fine.
