How to paint with a roller

When you’re painting a ceiling with a roller, keep the end of the roller facing the side of the surface that you have already cut in. This will make sure that the roller’s metal frame doesn’t damage your walls.

Step by Step Instructions

1 Check for moisture
2 Check you concrete isn’t sealed
3 Clean the concrete
4 Apply an acid wash
5 Apply the etching agent
6 Mask around the edges
7 Cut in the edges
8 Paint the rest of the concrete floor
9 Remove masking tape
  • Step 1. Check for moisture

    First, it’s important to make sure your concrete doesn’t have moisture rising up through it. If it does the paint won’t stick and will peel off. To check for moisture, lay a plastic bag on the concrete and tape it down so that it’s sealed. Leave it overnight and check in the morning to see if there’s any moisture on the plastic. If there is, you will need to get advice on the products you will need to use.

  • Step 2. Check you concrete isn’t sealed

    Check that you concrete doesn’t have any sealant on it by sprinkling some water over it. If the water is absorbed, it’s fine. If the water beads it has a sealant on it that will need removing using acid or an etching agent.

  • Step 3. Clean the concrete

    Use a garden hose or a high pressure cleaner to remove any dirt, sand or debris from the concrete. Then use a hard bristle broom to get rid of any ground in dirt on the concrete. 

  • Step 4. Apply an acid wash

    Put on your safety gloves and respirator before handling the acid. Depending on how damaged and stained your concrete is you might not need to dilute the acid. If it’s not too bad you can dilute it in a bucket of water. Use a hard bristle broom to apply the acid and scrub all of the concrete. Then hose the mixture off.

  • Step 5. Apply the etching agent

    Applying an etching agent creates a nice bonding surface for the paint. Put on the protective gloves and respirator. Follow the instructions and mix the agent in a bucket of water. Use the hard bristle broom to apply the etching agent and scrub all of the concrete. Rinse off the etching agent with a hose and let the concrete dry.

  • Step 6. Mask around the edges

    To protect your brickwork and walls around the concrete floor, place masking tape around the edges. This will also make it easier when it’s time for cutting in the paint with a paint brush.

  • Step 7. Cut in the edges

    Thoroughly stir the paint in the can before you use it. Also read the instructions on the paint can because it may need a primer, especially if your concrete has previously had paint or sealer on it. Pour the paint into a roller tray, then use a paint brush to cut in around the edges of the concrete floor.

  • Step 8. Paint the rest of the concrete floor

    After you have finished cutting in, use a roller on an extension pole to paint the rest of the concrete floor. Once the paint has dried you can remove the masking tape.
  • Step 9. Remove masking tape

    Once the paint has dried you remove the masking tape, some tapes will stick to your wall.

You need to be familiar with how to use equipment safely and follow the instructions that came with the equipment. If you are unsure, you may feel it is safest to consult an expert, such as the manufacturer or an expert Bunnings Team Member.

Grave health hazards are linked to asbestos, which may be in homes built up to 1990. Health hazards may result from exposure to lead-based paints in older materials and copper chromium arsenic (CCA) treated timber. For information on the dangers of asbestos, lead-based paint and CCA treated timber and tips for dealing with these materials contact your local council's Environmental Health Officer or visit our Health & Safety page. You can also use a simple test kit from Bunnings to indicate the presence of lead-based paint.
