Sealing your driveway is surprisingly easy. It will help protect brand-new exposed concrete or revive an old driveway that’s starting to discolour, making your home look like a million bucks. All you need are a few materials, a rain-free weather window and this helpful step-by-step D.I.Y. guide.
Safety tip: Always wear the appropriate safety equipment (safety glasses, ear muffs, gloves and mask, for example) and always follow the instructions for the product or equipment.
Cleaning your driveway will get rid of any grease, oil and debris that may have accumulated over time. This allows the surface of your driveway to become more porous, helping the sealant to apply and stick well.
If you have any petrol stains or other spills that may have accumulated over the years, these can be removed by using degreaser, a broom and a brush. For any areas that have moss or algae, use an appropriate cleaner before sealing.
You’ll also need to perform a moisture test. This is to make sure that your driveway is completely dry.
Secure some black plastic on the driveway with duct tape and leave it for a few hours. When you come back, check to see if there is moisture on the back of the plastic or if the surface has darkened. If so, be patient and allow more drying time before repeating the test. The plastic should be 100 percent dry before sealing your driveway.
Once your driveway is completely dry, you’re ready to apply the sealer. Make sure the sealant you have chosen is suitable for driveways. If needed, dilute the first coat as per the instructions on the can.
Once you’ve painted the edges, apply the sealer to the remainder of the driveway using a roller or stiff bristle brush. Allow to dry. If desired, repeat steps 7 and 8 to apply a second coat once the first has dried completely.
When you’ve finished, check the packaging and allow enough time for the sealer to fully cure before walking or driving on it.
Asbestos, lead-based paints and copper chromium arsenic (CCA) treated timber are health hazards you need to look out for when renovating older homes. These substances can easily be disturbed when renovating and exposure to them can cause a range of life-threatening diseases and conditions including cancer. 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.
When following our advice in our D.I.Y. videos, make sure you use all equipment, including PPE, safely by following the manufacturer’s instructions. Check that the equipment is suitable for the task and that PPE fits properly. If you are unsure, hire an expert to do the job or talk to a Bunnings Team Member.
