Synthetic filament paintbrushes
Synthetic filament paintbrushes are now the most common and best suited brush for general painting, especially
with water based paints. They are easier to use and clean. In most instances filament lasts longer than natural
Natural bristle paintbrushes
Natural bristle paintbrushes are used for all paint types but are particularly suited to oil based paints, stains and
industrial coatings. Natural bristle brushes hold more paint, have a softer finish and can be used for a wider range
Prior to use rinse brushes in solvent or water, dependent on the paint type, to remove any loose bristles. Make sure
the brush is dry before use.
Loading the Brush with Paint
Dip no more than half of the brush bristle into the paint. Tap off excess paint by gently tapping the brush against
the side of the paint can.
Paint Application with a Brush
• Start at the top and work your way down. This process allows drips to be painted over.
• Hold your brush like a pencil to achieve the best control.
• Apply paint using the brush tips and hold the brush at a 45 degree angle to the surface using an even pressure.
• Apply paint in long smooth vertical strokes.
• When painting timber always paint along the grain.
• Finish off and remove any brush marks by painting from the painted area to the unpainted area and back.
This will create a smooth painted finish.
• Concentrate on one area at a time until evenly covered. Avoid excess re-brushing.
• Move to the next section and repeat above steps.
Using a brush paint a 50–100mm border around the wall surface. This is known as cutting in. Cut in around power
points and light switches using a smaller border of about 25-50mm. When completing your project do not paint
over the area that has been cut in by the brush.
Clean up and care:
• Never leave a paint-covered brush exposed to air for any length of time. Wrap in a plastic bag or cling wrap
to keep moist and ready to be used again.
• Never leave a brush in solvent or water for extended periods of time.
• Make sure brushes are cleaned thoroughly after use and stored correctly.
• See Brush and Roller Care and Cleaning for full cleaning and product care instructions.
