  • Step 1: Clean the area

    Ensure the garage is well ventilated by opening any doors and windows.

    Use an outdoor broom to brush the surface to remove any debris and surface dirt.

    Remove dirt, grease, and stains using a medium - stiff bristle brush and a driveway cleaning solution.

    If the surfaces have a build up of fungus, algae or mildew, scrub them with an anti fungal solution.

    Rinse with a pressure washer or, alternatively, a hose with good pressure then allow to dry.

    Always read the instructions of the products prior to use.

  • Step 3: Apply the sealer

    Use a concrete sealer to prepare the concrete ready for paint. Use a small to medium paintbrush to paint the edges and the hard to reach areas. Use a long handled roller and paint tray to paint large flat surfaces. Check the product's instructions for the correct drying time, don't rush this stage.

    Shop primers and undercoats

    Heavy traffic areas will likely need recoating approximately every year.

  • Last step: Finishing up

    Remaining paints, stains and oils should be stored or disposed of
    according to their individual instructions. Do not empty down drains.

    Remove as much of the product from the brushes, rollers or paint pads
    before cleaning.

    If you have used water-based paints, simply wash with water. Work a little
    soap into them, rinse them clean and leave them to dry.

    If you have used oil or solvent-based paints or stains, simply clean with
    a solvent such as white spirit.
