Painting Tips

How to choose colour

Colour reflects who we are and who we aspire to be. It’s expressive, fun, creative, complimentary and always conversational. That’s why we want to provide you with the best tools to find your perfect paint colour. Browse our Colour Wall online or check out our Colour Booklets for colour, texture and scheming ideas.

Colour Choice Choosing the perfect colour is never easy but help is at hand. The best place to start is a Dulux colour brochure followed by picking a selection of colour chips from the Dulux Colour Wall. The Dulux colour schemes are also a great help in choosing the perfect mix of colours for your home. It is worthwhile considering applying a texture to a feature wall to add some interest and individuality to your living space. Sample Pots It is always important to remember that colours can appear to change in larger areas and under different lights. Dulux Colour Solutions® Sample Pots are a great way to help test your colour selection. Dulux Mycolour® The Dulux Mycolour® visualizer is also a fantastic aid in helping with colour choice. You can create colour schemes with confidence without leaving your lounge room. Sheen Levels When choosing paint it is important to choose sheen levels carefully. The reason for this is the sheen level can dramatically change the look of your walls. For example, flat and low sheen paints hide surface imperfections better than gloss paints, which is the reason they are used on most walls and ceilings.

Colour Variation

Apparent colour variations between the paint chips on colour cards and paint on the wall are usually caused by the reflection of another light source. For example, a nearby garden can affect the appearance of a pale yellow or cream paint coating. Perception of a colour can also be altered by a reflection coming from floor coverings or curtains. Use Dulux Sample Pots to check the paint in place before you purchase the full quantity.

Preparations

Good preparation is the key to a great result that’ll stand the test of time. Remember, paint shouldn’t be used to cover holes and cracks (a poorly prepared surface is often the major cause of poor results).

Interior & Exterior Surfaces It is essential that paint is applied to a clean surface. For the best result use Selley’s® Sugar Soap and a scrubbing brush to remove dirt and grease from walls, rinsing with water, and then allow to dry. However, if the paint has peeled and bubbled it will need to be removed with a wire brush or scraper and then sanded. Wipe down before painting. Apply the masking tape along edges where you don’t want any paint. When repainting doors, window frames or trim ensure that the gloss surfaces of oil-based enamels are sanded until matt before applying Primer Sealer & Undercoat.

  • Protect unpainted surfaces and furniture
  • Move all furniture out of the room. If you don’t have a lot of space, move it into the middle of the room and cover with a cloth or drop sheet.
  • Lay down a proper drop sheet to protect your flooring. Try not to use old sheets, they are too absorbent and the paint will often soak through.
  • Mask skirting boards and trims with suitable masking tape.
  • Mask electrical switches instead of removing them; it’s much safer and will reduce your workload.
  • Mask the corner when painting adjacent walls with different colours. This will help to protect the wall you’re already painting and make it easier when cutting in.
  • Prepare the surface
  • Remove all loose, flaking or powdery paint from previously painted surfaces with a scraper.
  • Wash all surfaces with Selley’s® Sugar Soap, as any dust and dirt will prevent paint from sticking.
  • Patch any cracks and holes with a suitable filler or sealant such as Selley’s Spakfilla®.

Sand down to a smooth level surface and dust off.

 

Your surface is now correctly prepped for painting.

 

Painting and product advice

When to paint

The temperature of your house affects the performance of paint. The wall temperature must be above 10C throughout the painting process. You should generally avoid painting in extremely hot or cold conditions. If it looks like rain, remember the painter’s rule; if you wouldn’t hang the washing out or wash the car, don’t paint! Nothing is more disappointing than seeing your work ruined!

Using acrylics in hot weather

Because most acrylics are touch dry in twenty minutes at 25 degrees and 50% humidity, the hottest weather in the summer months will accelerate this drying process. To slow down the drying rate, Dulux Hot Weather Thinner may be added to the paint at the rate of 50ml per litre. A good tip for painting in summer is not to paint in direct sunlight or onto a hot surface. Try to follow the shade where possible. You can add up to approx 5% water. Also using 2 brushes – keeping one in a bucket of water and alternating them, stops them drying out.

Choosing enamels or acrylics for exterior use

We would generally recommend the use of acrylics in exterior situations. As enamels age they become very brittle and chalky and therefore have a tendency to crack and flake off the surface. Acrylics, however, retain their colour better, do not chalk to any great extent and do not become brittle, giving a longer lasting, more durable paint finish.

The greater flexibility and UV protection of Dulux Weathershield is the preferred option

 

Safety information

Basic safety information is included on the labels of our products. For more information, you need to obtain a Material Safety Data Sheet on the individual product. This information is available from the product sections of this website, or you can call Dulux Customer. Please be sure to specify the exact product you require.

Determining if your old painted surface contains lead

In buildings, which are very old, it is possible that some of the original paint or primers may still contain lead. Extreme care should be taken with the removal of these coatings. They should not be sanded or burnt. Independent chemical laboratories can test paint flakes for lead.

How to use a paint brush

Painting window frames, skirtings, doors and mouldings are worth doing carefully to get the best results. Always work in sections and paint up to a natural break before stopping. Start at the top and work down, painting with light even strokes, working back into the wet edge.

 

Never try to paint over an area that is partially dried, as the brush will leave marks in the surface. If you see a run in the wet paint, paint over it as soon as possible with light even strokes.

– Before use, moisten the brush in water if you are about to use a water-based paint, or turps if you are about to use an oil-based paint. Make sure you remove excess liquid before painting.

– Fill the brush by dipping in up to half the length of the bristles.

– Tap it gently against the side of the can: don’t wipe the brush hard against the lip. The bristles should flex only slightly as you brush – don’t over press – let the paint flow from the brush.

– If you are painting a large area by brush, apply paint to an area about 50 cm X 50 cm, then brush the paint in horizontal strokes to even the paint out and finish off with light vertical strokes all in one direction. If you are using a brush and roller, paint the edges of the area first.

 

How to use a paint roller

Which roller nap length should I use? The nap or pile refers to the length of the roller’s fibres. • Use a 6mm short nap for smooth surfaces and high gloss paints. • Use a 12mm medium nap for ceilings, walls, low sheen and flat paints. • Use a 20mm long nap for rough surfaces. Brush The perfect grip for holding the brush is between the first finger and thumb, resting the fingertips on the top of the brush. Dip half the bristles into the paint and wipe the brush on the side of the can to remove excess. For the best result use short brush strokes when applying the paint. Roller After pouring the paint into the tray, dip the roller into the paint and then roll it back and forth on the shallow part of the tray to ensure even coverage. If you apply the paint too heavily it may splatter. Use an even pressure throughout application.

 

To use a roller you’ll need a tray, frame, roller cover and possibly an extension pole. Make sure you have the right roller for the job new roller sleeves prior to use by washing them in water.

  1. Fit the roller to the frame.
  2. Pour paint into the reservoir at the end of the roller tray. Do not overfill.
  3. Dip the roller lightly into the paint, then roll it backwards and forwards on the ramp to evenly distribute the paint on the roller cover.
  4. Roll the paint onto the surface with in a zig-zag pattern.
  5. Once you’ve covered the area, level the finish by laying-off with long, parallel strokes. Laying-off needs to be done before the paint has commenced drying, so it’s best to work in sections at a time.
  6. Never leave a paint-covered roller exposed to the air for any length of time.

 

Wrap it in plastic cling wrap when you take a short break, and make sure to clean it completely after use.

To begin the clean-up remove as much excess paint as possible by brushing or rolling out on newspaper. Be sure to wash brushes, rollers and other equipment in water.* It is vital to rinse equipment well and, if necessary, straighten brush bristles with an old comb. Leftover waste paint If you have any leftover waste paint, dispose of it in an environmentally friendly way using Dulux Envirosolutions® Waste Paint Hardener. It turns unwanted water-based paints into solid waste for easy household disposal. Simply pour the Waste Paint Hardener into the remaining paint and stir until it solidifies. Leave for 2 hours with the lid off. Now you can easily remove the hardened paint from the can, wrap it in newspaper and dispose of it via your domestic waste.

 

Paint clean up & disposing of unwanted paint

  1. If you are planning to continue your painting project the next day, just keep the paint, brush and/or roller in the paint tray and cover with foil or cling wrap. The next morning, run the brush or roller over a newspaper a few times and it will be ready to use.
  2. To begin the clean-up remove as much excess paint as possible by brushing or rolling out on newspaper. Be sure to wash brushes, rollers and other equipment in water or mineral turps for solvent-based paints.

  4. Wrap the clean brushes and rollers with newspaper and secure with a rubber band. Store the brushes flat or hang them on hooks

Do not use a spinning tool to clean brushes, as this will make your brush flare.

  1. Wrap the clean brushes and rollers with newspaper and secure with a rubber band. Store the brushes flat or hang them on hooks.
  2. Never dispose of unwanted paint by pouring it down household or stormwater drains. Water-based paints can be treated with Dulux Envirosolutions Waste Paint Hardener. This product turns the liquid paint into a solid mass, which can then be placed in household waste. The can, once emptied, can be placed in household recycling bins. Unwanted solvent-based paints can be disposed of by pouring the excess onto an absorbent material such as kitty litter, cardboard or shredded paper. Allow to dry and dispose with your normal household waste collection. For the disposal of larger quantities of paint, contact your local council.
