Spray painting is fun, and a little practice will enable any amateur to obtain professional results.
Why do I have to shake well?
a.
High quality ingredients and very high pigmentation levels guarantee good coverage. Shaking
the can well ensures that the pigments and other ingredients mix well for a perfect job.
Shake the can until you hear the ball rattle, and then for at least a further two minutes.
Periodically during use shake the can for 5 to 10 seconds to ensure that the ingredients remain
properly mixed.
Always perform a test spray on a piece of paper or cardboard prior to application on your
object of choice.
Is it necessary to use all of the contents at one time?

No. The valve on top of the can automatically seals itself.
As long as you adhere to the directions in the next couple of sections you will be able to use
your Dulux Duramax until the can is empty.
Follow these simple tips to help ensure that your Dulux Duramax spray paint is evenly applied
to your project every time.
Shake your Dulux Duramax spray can vigorously for two minutes after the ball within the can
begins to rattle.
Test your spray paint and painting technique on a piece of scrap material until you have
achieved a satisfactory result.
To ensure surface compatibility, test spray on an inconspicuous area before continuing with
the whole project. (Some surfaces may need pre-treatment or be unsuitable for painting)
Hold can upright 10 to 25cm from the surface.
Begin and finish your spraying off the object, releasing the tip at the end of each pass
IMPORTANT TIP: Make sure that you start to move your hand with the spray can before you
depress the nozzle.
Spray with smooth, even strokes parallel to the surface in an even side-to-side motion.
Overlap your previous spray pass by about one-third with each successive pass
For smoothest results, we suggest always applying a coat of a Dulux Duramax primer before
applying any Duramax® Top Coat.
Even though Dulux Duramax is formulated to resist running and sagging. It should be applied in
one or more light coats, as opposed to one heavy coat.
Release the trigger at the end of each stroke, to avoid a build up of too much paint at the ends.
DO NOT HOLD the valve open while the spray can is stationary as this will result in a heavy
deposit of paint that will sag.

Prevent blocking by turning the can upside down and spraying until clear gas emerges. ( 2 - 3
seconds of spray) Also wipe front of the nozzle clean. The spray tip is attached to a valve and a
tube system that draws material from the very bottom of the can.
When you turn the can upside down, the end of the tube is no longer in the paint but in a free
gas layer inside the can. When the spray tip is depressed with the tube in free gas, it purges all
paint from the tube valve and the spray tip leaving the system clean for next use.
Clean up any paint on the nozzle while it is still wet with mineral turps.

The following comments apply only to the Dulux Duramax range from Dulux®.
Other Dulux spray paints use a valve and nozzle combination where it is not recommended to
remove and replace nozzles. Dulux Duramax has a nozzle design that allows replacement and
fitment of different nozzles as needed.
When aerosol paints were first introduced, this was the number one complaint. However,
technical improvements in both product and valve have practically eliminated this problem.
If the spray nozzle becomes clogged, rotate the nozzle by a 1/4 turn and try spraying again. If
the spray nozzle continues to be clogged, remove and clean the nozzle stem using a toothpick
and/or by soaking in acetone or comparable solvent to remove dried paint.
You may be able to interchange spray nozzles from another Dulux Duramax can. DO NOT stick
pins, wire or other objects into the hole on top of an aerosol can.
Remember, after using an aerosol can it’s important to clear the valve to avoid having a clogged
spray nozzle which affects future performance. We recommend that after
each painting project, invert the aerosol can and press the nozzle until
clear propellant gas is emitted, normally for
2-3 seconds.
b.
c.
Dulux Duramax contains a rapid dry formulation that ensures the coating
is touch dry in 20 minutes and ready to use in 1 hour.
If the weather is very cold – less than 10oC – or very hot – more than 35oC
avoid spraying if possible. High and low temperatures can have impacts on
drying rate and gloss of the finished part.
Where possible avoid spraying items in direct sunlight

Dulux Duramax can cover up to 4.5m2 per can depending on the surface
and colour used.
Since spray paint is not recommended as a substitute for conventional
paint in painting large, flat surfaces, it should be sold for what it does,
rather than how much surface it covers.
Coverage depends on the type of surface, porosity, thickness of
application, original colour, surface profile and shape of the object and
the skill of the painter. The benefits of using aerosol paint are the quality
of the finish, time and convenience. No brushes or cleaning solvents are
required.
The cost of the can of spray paint is less than a good quality paint brush.
Dulux Duramax –FREQUENTLY ASKED QUESTIONS
Using a primer improves the amount of coverage you get from a can of Dulux Duramax top
coat and it provides additional benefits for the following surfaces:
Metal – Increases corrosion resistance on bare metal surfaces
Wood – Helps avoid an uneven paint finish by sealing the surface and reducing uneven
penetration of bare wood surfaces
Plastic – provides a necessary “key” into the plastic surface to help secure the top coat to the
object. (Important Tip: Not all plastics can be painted.)
Unlike some Aerosol paint manufacturers, Dulux does not supply a “Paint and Prime” option
in the Duramax® range. Dulux recognises that in many applications primers are not required.
Dulux is of a view that the compromise of final paint performance by inclusion of primer
components is unnecessary. Since the top coat is what a user wants to perform in both visual
and protective capacities, it is better to focus on building theses properties into the top coat
and use purpose built primers where they are required.
[ 15 ] Can Dulux Duramax be used on Plastics?
[ 10 ] What is the coverage of Dulux ® Duramax® ®?
a.
A primer is designed to prepare bare metal, wood, canvas plastic or other materials to create
a smooth surface for which your Dulux Duramax can be applied. A primer should be used on
projects in order to seal the surface which will help:
I. Smooth out uneven surfaces and cover blemishes
II. Increase paint adhesion on difficult to bond substrates
III. Improve corrosion resistance (on metal substrates)
IV. Ensure that you achieve the truest colour of the paint by “hiding” any colour input
from the substrate
[ 14 ] Why Should I Use A Primer?
[ 9 ] How long does Dulux ® Duramax® ® spray paint take to dry?
a.
Where possible move the object to be sprayed so that you can get access to the hard to reach
areas without needing to contort yourself to do so.
Dulux recognizes that all spray paint projects are unique, and therefore a flexible approach to
product application may be required. In response to needs for adaptable convenience, Dulux
supplies on its Dulux Duramax colour paints, a general purpose nozzle that can handle projects
small and large, short and wide.
This General Purpose nozzle has a relatively narrow fan width to assist with proper paint
placement and minimise overspray. Additional nozzle configurations are available as part of a
Dulux Duramax accessory pack. For some applications you may find it better to use a nozzle
with a different spray pattern from the accessory pack.
[ 13 ] What is primer and when should I use it?
What should I do with a clogged spray nozzle?
a.
b.
Dulux Duramax can be recoated anytime after becoming touch dry (20 minutes).
This does not mean you should apply a single light coat then wait 20 minutes. Multiple light
coats to build to a single coat with full cover are acceptable.
After you gain coverage, wait for the 20 minutes than apply a second series of light coats.
Now wait for 1 hour, or the dry time specified and start using the item. (Important Tip:
Not all Dulux Duramax products dry in 1 hour – directions are provided on the can)

Applying Dulux Duramax spray paint in ideal weather conditions can help prevent bubbles
from forming on the surface of your project. We suggest applying Dulux Duramax when the
temperature is between 10 and 35oC with a relative humidity below 85%.
In addition to this, we suggest applying the paint according to the manner outlined in the
preceding FAQ.
If bubbles do occur:
i. Allow spray paint to dry
ii. Lightly sand the affected surface to remove all traces of the bubbles
iii. Reapply Dulux Duramax under correct environmental conditions and using the
previously described application method.

Some plastics like polyethylene and polypropylene do not allow for paint adhesion,
even with primers.
Try to identify the type of plastic an article is made from before starting your project. Some
plastic products will be marked with recycling information or with markings advising the type
of plastic. If possible use these as reference information to define the plastic.
For those plastics you cannot identify test in an inconspicuous area first.
Hard plastic like uPVC pipe should be sanded with a fine (800 grit) wet and dry paper then
wiped with alcohol before top coating.

8 – DULUX DURAMAX PRIMERS FOR OTHER SUBSTRATES
Dulux Duramax –FREQUENTLY ASKED QUESTIONS
[ 18 ] Is Dulux Duramax able to be polished when it’s fully cured?
a.
Yes, Dulux Duramax allows for the finished top coat to be polished again and again, ensuring
that your projects continue to look great!
b.
Products from the Turtle Wax® range can be used for this purpose.
PREPARATION

How do I prevent my spray can tip from clogging?
[ 2 ]
How do I prevent spray paint overspray?
[ 19 ] Why does my paintwork get runs in it?
a.
There are several reasons why this may be occurring. If you are holding the can in one spot
- rather than using a sweeping motion -the paint tends to build up and form a run. You may
also be holding the can too close to the object you are painting. For best results refer to the
previous point on “How to apply paint evenly”.
b.
The temperature of the spray paint can and the object should be roughly room temperature.
c.
Any extremes in temperature, distance to substrate, or failure to keep the can moving when
the valve is open, can cause irregularities in the finished paintwork.
[ 20 ] Why does my paint get cracks in it when it has dried?
a.
This occurs for a number of reasons. If you apply a primer, (or a more highly pigmented paint)
to a topcoat this can cause flaking and cracking.
b.
Cracks also appear from poor preparation. Always clean and degrease all surfaces to be
painted. Sanding previously painted or new surfaces with a very fine paper (600 grit or finer)
will assist with obtaining adhesion.
c.
Use the recommended primer from the Dulux Duramax range to prime all surfaces for
maximum adhesion and elasticity of your final coat.
d.
We always recommend using the same brand of product throughout the painting process.
e.
Different companies have differing chemicals in their paints and this can cause reactions
between coats.
a.
a.
Overspray can occur both indoors and outdoors. Depending
on your project and location of your spray paint area, there
are many materials that can be used to cover surrounding
surfaces and protect them from overspray (newspapers,
tape, drop sheets etc.).
b.
Avoid spraying in an area subject to windy conditions.
Aerosol spray particles are very fine and have little
momentum so can be easily misdirected by even light
breezes.
c.
Ensure that you do not spray from further away that 25cm
from the target surface. The further from nozzle to target
the greater the loss of particle momentum and the easier it is
for a breeze to push it off course.
d.
All spray nozzles are designed so that they create a fan.
This is set to a certain angle. Most Dulux Duramax colours
and primers are set with nozzles to provide a fan between 9
and 13 degrees. Some manufacturers work with 30 degree
nozzles. The wider the spray fan angle the more likely that
overspray will occur as the distance to the target object
increases.
e.
Some objects that you want to spray will be contoured,
rounded or have openings in them. Typical of such items is
a wicker seated chair. When spraying such items, obtain a
larger cardboard box, open it up to make a three sided room into which you can place the chair
and spray from the open side. This will help reduce breeze influence on paint placement and
reduce potential for overspray to get on objects you do not intend to coat.
f.
If necessary mask and cover all items in the surroundings with a low cost, impermeable plastic
drop sheet and use masking tape to secure in place.
[ 21 ] Why are there colour variations, from the one can, in my paintwork?
a.
The most common cause of this is from not shaking the can for long enough.
b.
Shake the can until you hear the ball rattle and then for at least a further two minutes. This
ensures the contents have completely mixed, as they may have settled and separated during
transport.
c.
Colour variations can also occur when parts of a coat are missed or applied too lightly. Please
ensure all areas are sprayed, in two coats, from a distance between 10 – 25 cms.
[ 22 ] Why doesn’t my painted surface have a glossy look to it?
a.
This generally occurs when the spray can has been held too far away from the object while
spraying. The paint dries in the air before it hits the surface and forms a rough layer on the
object. Always hold the spray can at a maximum of 25cm from the object.
b.
If you have used a less than full gloss product then simply apply two layers of clear coat after
the coloured paint has dried.
Prevent blocking by turning the can upside down and
spraying until clear gas emerges. Also wipe front of nozzle
clean. Clean up overspray while it is still wet with mineral
turps.

What clear coat spray paint will protect my digital photos
or items around the home?
a.
b.
[ 2 ]
Dulux Duramax comes in a range of acrylic clear coats that are perfect for protecting digital
photos and other items around your home.
b.
A primer is designed to prepare bare metal, wood, canvas or other materials to create a
smooth surface for which your Dulux Duramax spray paint will be applied. A primer should be
used on projects in order to seal the surface which will help:
i. Smoothen out uneven blemishes
ii. Increase spray paint adhesion
iii. Improve corrosion resistance
iv. Ensure the true colour of the spray paint
Generally, using a primer improves the amount of coverage you get from a can of Dulux spray
paint and it provides additional benefits for the following surfaces:
Metal – Increases corrosion resistance on bare metal surfaces
Wood – Helps avoid an uneven paint finish by allowing for even penetration of
bare wood surfaces
iii. Plastic – Increases the adhesion of the topcoat on this normally, tough to adhere
surface.

Dulux Duramax –FREQUENTLY ASKED QUESTIONS
Can I remove sand, dirt or grass from wet or tacky spray painted surfaces?
a.
No, you should wait until the paint has dried to a point that you can abrade it back with fine
sandpaper to remove such imperfections then start over with spraying.
b.
When respraying place the object to be sprayed in an environment where contaminants do not
have a potential to deposit into the wet paint.
Can I spray Dulux Duramax over previously applied enamel paints?
a.
Dulux Duramax has a unique solvent system to aid in its fast dry character. This solvent system
has a tendency to lift or raise some previously enamel painted surfaces. When this happens
the previously applied paint looses adhesion from the surface and can peel away immediately,
or over time.
b.
Test carefully in an inconspicuous area on pre-coated objects before proceeding.
How do I remove pre-existing paint before applying Dulux Duramax?
a.
If a test shows that Dulux Duramax has an effect on a previous paint system then follow the
directions below.
b.
Where necessary remove pre-existing paint before applying spray paint using heat or a suitable
environmentally acceptable paint remover. (Selleys® Kwik® Strip Smart paint & varnish
stripper is a suitable product of this type.)
c.
After the paint is removed clean and sand the project surface before application of an
appropriate primer from the Dulux Duramax range. Once the primer is dry the surface is ready
for Dulux Duramax® to be applied.
Why does the colour appear to be flat or hazy?
a.
Humid conditions may exist. Try again under less humid conditions.
b.
Surface you are spraying may be too hot. Remove the object from direct sunlight or heat; allow
surface to cool and continue.
c.
Make sure the aerosol can and surface temperatures are between 10 and 35°C. Dulux
recommends that you check your local weather conditions before you paint.
How long can Dulux Duramax be stored before use?
a.
Generally Dulux Aerosol paints are designed to be suitable for use for up to 2 years from date
of manufacture when stored at temperatures between 10 and 35oC
b.
Experience demonstrates that some Dulux Aerosol products prepared several years ago
still work perfectly; since the cans are sealed, it is doubtful that much could happen to the
contents.
c.
All Dulux Duramax products carry an unconditional guarantee for two years from Date of
Manufacture. Should there be a defective valve or a can that does not spray properly it will be
replaced immediately.
Is temperature important when I store an aerosol can?
a.
For best results, aerosol cans should be stored upright and between 10 and 35°C.
b.
Storing aerosol cans upside down can cause pigments to settle in the neck of the can or in the
valve and cause blockage.
c.
Cold temperatures usually won’t harm aerosol cans, however always let cans settle to room
temperature before using.
d.
Dulux recommends NOT storing aerosol cans at extreme temperatures for prolonged periods
of time.

Why don’t metallic colours match?
a.
Dulux Duramax Metallic paints are designed to be very robust so they can accommodate a
wide window of application methods. However, the paints cannot compensate for all the
things that people try to do with them. Therefore it is important to understand how these
paints work so you can perfect your application technique and get the best from this truly
wonderful range.

What are aerosol paints?
b.
When spraying a metallic colour, you are actually spraying tiny flakes of metal in a paint coating.
These flakes reflect light. The more light they reflect, the brighter the coating appearance.
a.
c.
When metallic paint is applied too heavily, the metal flakes are being buried under the surface
of the paint coating. Here, they can’t reflect light and the colour appears dark and sometimes
dull.
b.
d.
e.
c.
When metallic paint is applied too lightly the metal flakes lie on top of the paint coating and
reflect too much light, making the paint appear lighter and brighter in colour. In this situation,
the metal flakes aren’t being covered by enough paint.
By varying your spray technique you can achieve the colour and effect you want. Practice on
a piece of metal before painting your intended object. There is no substitute for experience
when spraying a metallic colour. Once you get it right you will find the Dulux Duramax products
capable of providing new and exciting finishes not available elsewhere.

The aerosol delivery system comprises:
i.
A can capable of handling the high pressures resulting from the use of liquefied
gas propellants.
ii. A valve and dip tube assembly to firstly seal and contain the contents under
pressure, and secondly to be easily activated with finger pressure to open and
allow the contents to escape.
iii. A nozzle arrangement configured to allow the controlled application of the
contents of the container onto the surface it is intended to coat.
The contents of the can comprise
iv. Solvents or water in which the paint is dissolved or suspended.
v. A blend of compatible ingredients made from pigments and resins and other
additives that will remain after the propellant and the solvents have evaporated.
These you see as the paint film that remains.
How is an Aerosol can assembled?
b.
c.
14 – Aerosol paint is a finely dispersed pigment, solvent, and resin blend mixed with a propellant in
solution.
Filling aerosol paints is more complicated than filling a can of brush-type paint. It requires a
special technique and special equipment.
Aerosol paint formulations require skill, and experience to make paints that, when sprayed
from an aerosol can, will give a paint finish that is better than you get with a conventional paint
using a brush or roller application.
The dictionary describes an aerosol as a”suspension of fine solid or liquid particles in air or
gas.” However, the term”aerosol” is now applied to all push-button products propelled by gas
from a container.
Today, thousands of consumer products are provided in safe, efficient and convenient aerosol
formats.
Firstly the paint component is filled into the aerosol can at atmospheric pressure. At this time
the valve and spray nozzle assembly are not present.
Diluent solvent required to lower the viscosity of the paint is then added.
Depending on the process the valve and nozzle assembly are either crimped in place at this
stage or a later stage in the process.
For aerosol paints with valves that are crimped after the addition of the diluent solvent the
can is filled under pressure through the valve that has been crimped in place. This is called
“through valve filling”.
In another process the can containing the paint and diluent solvent is passed under a head that
first injects the propellant gas then inserts seals and crimps the valve assembly in place. This
process is called “under-cup filling”.
Through Valve filling is a lower cost option as the machinery to do the job is less expensive.
However, line speeds using through valve systems are slower and there is an ever present
danger of damaging the valve as the gas is injected.
Under cup filling is more expensive to set up but the faster line speeds and lesser prospect of
damage to the valve during the gas charge process make up for the increased machinery costs.
In both cases the propellant creates an internal can pressure of about 30 - 80 psig at room
temperature, by creating a gas phase in the head space of the container.
When the nozzle is depressed, the airtight valve opens and paint, diluent solvent and
propellant, mixed together in a precise ratio, flow up the dip tube to the nozzle.
On reaching the nozzle the liquid gas is in a low pressure environment and rapidly expands
causing a continuous micro explosion field just beyond the nozzle tip. This action divides the
paint into small droplets and gives them momentum to push forward to the substrate.
As the product is used, the head space increases, creating more gas and providing a constant
pressure down to the last gram of product.
