Over time, as an asphalt driveway ages, small stones in the asphalt become dislodged. The asphalt can loose its ability to hold together and can start to break up. Dirt becomes ingrained, moss begins to grow. Weeds appear and the driveway gets worn down from use and general wear and tear. Old age comes to us all!
The life of a driveway can be extend, or it’s appearance can be improved, by painting it with bitumen. The bitumen:
Fills the gaps and pits that were once filled with dirt.
Helps prevent moss and weeds from growing (and breaking up the surface).
Binds any loosened stones together.
Helps prevent the stones in the asphalt from lifting (tyre wear, and general wear and tear).
A power washer (preferred), or a hose with spray attachment.
Paint brushes, (roller or an old soft broom – These should be throw away items).
A pot for storing dirty brushes (so they don’t dry out).
The driveway is looking a bit tired. There are loose Stones, moss, dirt and weeds.
What can we do to repair or refresh the driveway? We can clean and paint the driveway with Bitumen paint!
The easiest way to do this is to first, is to sweep the driveway, then power wash it, (be careful, try not to damage the driveway). If you power wash straight away, it usually means you’re just pushing the dirt & debris around.
Sweep up as much of the dirt as you can. Then power wash it.
Washing the dirt away provides a good key for painting.
I’m using a water-soluble bitumen paint, (there are other types of bitumen paint that need thinners).
Use a watered down first coat as a primer. This helps the bitumen paint stick to the driveway.
Work the bitumen into all the pits and holes in the driveway using a brush.
Follow the manufacturer’s instructions for, drying times and the number of coats needed.

Notes (Hints & Tips):
Move any items that can get splashed with Bitumen (especially plastics), as it can be difficult to clean off.
The darker colour will lighten with time.
You could use a broom or a roller to paint the bitumen onto the driveway.
Store brushes in water (for water-soluble bitumen).
Be prepared to throw any brushes out when you finish, as they may be difficult to clean?
