Preparing a driveway properly before sealing is just as important as choosing the right sealer.
Cleaning, repairing any damage and allowing the surface to dry properly all play a part in getting a good, long-lasting finish.
Here at Swiss Seal, we always recommend spending time on preparation rather than trying to rush straight into the application. A sealer can only do its job properly if it is applied to a suitable, clean and dry surface.
How do you clean a driveway before sealing?
The first step is to give the driveway a thorough clean. Remove dirt, dust, leaves, moss, algae, weeds and any other loose material from the surface. Pay particular attention to the joints if you have block paving, as these can collect a surprising amount of debris.
For more heavily soiled surfaces, a suitable driveway cleaner can help loosen ingrained dirt and organic growth. Pressure washing can also be useful, provided it is carried out carefully and is appropriate for the paving.
Once cleaning is finished, remove any remaining loose debris and inspect the surface.
Do you need to repair the driveway first?
Yes, deal with repairs before applying driveway sealer.
Look for cracks, damaged blocks, loose areas, missing jointing sand or other problems that could affect the finished surface.
With block paving, individual damaged blocks can often be replaced, while joints may need to be refilled with suitable sand.
If you are preparing a concrete driveway, check for cracks and areas of deterioration.
Minor repairs should be completed and allowed to cure properly before sealing.
There is little point sealing a surface and then carrying out repair work afterwards, as you may end up damaging the new finish.
Does the driveway need to be completely dry?
Yes, the surface needs to be properly dry before applying sealer.
This is one of the most important parts of driveway preparation for sealing. Water can remain in porous paving and within block paving joints even when the surface feels dry to the touch.
Always follow the drying time recommended for your particular sealer. Weather conditions make a difference too, so don't just work from the clock.
In the UK, it's worth keeping an eye on the forecast before starting the job. Ideally, choose a period of dry weather and avoid sealing if rain is expected shortly afterwards.
What else should you check before sealing?
Before you start your driveway sealer application, make one final inspection of the whole area.
Make sure there are no weeds or loose debris left behind and check that repairs have been completed. If you're sealing block paving, make sure the jointing sand is where it needs to be.
It is also worth protecting nearby walls, doors, drains and other areas that you don't want sealer getting onto.
Good driveway preparation takes a little time, but it can make all the difference to the finished job. Clean it properly, make the necessary repairs, allow everything to dry thoroughly and follow the instructions for your chosen product.
At Swiss Seal, that's the approach we recommend every time. Don't rush the preparation and expect the sealer to sort everything out afterwards. Get the groundwork right first, and you'll give the sealer the best possible surface to work with.
