Revitalise your exterior brickwork using Dulux Weathershield designed specifically for Australian conditions.

What you will need

Before you start make sure you have the right tools:

  • Drop sheets 
  • Medium-size, angled brush 
  • Paint tray 
  • Roller frame
  • 18mm nap roller cover 
  • Paint Stirrer 
  • Extension pole for hard to reach areas
  • Dulux Weathershield paint 

Before you paint

Before you paint ensure you have properly prepared the area.

  1. New brickwork with cement mortar should be left to set for a minimum of 28 days before painting.
  2. Check your brickwork for any defects. A build up of white crystal salts on the surface is called efflorescence and needs to be removed before painting. To remove any efflorescence, wipe down the bricks with a 5% solution of white vinegar and water, hose down then allow to dry.
  3. Check the bricks for any water damage. Any leaks, damp rising or excess moisture will need to be addressed before painting.
  4. Ensure the surface is clear of any loose sand or cement. Fill holes with grouting cement.
  5. Wash down with water using a stiff brush to remove all loose material.
  6. Use a good quality masking tape along any edges you don’t want to paint, including trims or windows.

Quick Tip

Quick Tip

Before you begin, stir your paint to ensure a consistent colour across the job. Your brush and roller soak up more paint when they’re damp, so wash them prior to use.

Painting your bricks

  1. Cut in around the edges and hard to reach areas with an angled brush using Dulux Weathershield.
  2. Using an 18 nap roller, load the tray with a reasonable amount of paint.
  3. Start rolling the wall in an ‘M’ pattern. Continue over the same section until the wall is evenly covered. Roll up to area of 1m2 size or paint the wall in sections.
  4. Before paint starts to dry, using an unloaded roller, begin in the top left corner of your wall and gently let the roller roll down to the base in a straight line with no pressure. Repeat this action only this time, slightly overlap your last movement so your roller rubs away the line created by the previous stroke. Continue this across the area you have painted. This is called laying off.
  5. Once the first coat is dry, approximately 2 hours in normal conditions, repeat the total process again with a second coat. Bare bricks will require the application of a third coat.
Quick Tip

Quick Tip

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 break or between coats, and make sure to clean it completely after use.
