How to seal block paving driveways

We make it easy for DIY'ers to seal their own driveways and patios.

All it takes is the right chemicals, equipment and a bit of time to achieve that professional finish.
The result: Money saved and DIY satisfaction


Starting with good quality materials will make a huge difference to your project, using cheap or inferior sealer to save money will result in wasted time, effort, weeds coming back through within 6 months and your project needing to be completed again.

Want to spray on your sealer?
For solvent based sealer you will need a course droplet low level pump sprayer with fan jet tip, this sprayer will need to be highly solvent resistant or it will fail after a few minutes of using due to the solvents destroying the "O" rings. If you wish to keep the sprayer for use another time, you will need to purchase our Sealer Thinners to clean it. 

For spraying solvent free sealer like our Eco HD Block paving sealer you will need a similar sprayer but no need for solvent resistant seals as it cleans with soapy water. Even so, our advice for applying solvent free sealer is by broom or roller as the product needs to be applied quite heavy

The effects of sealing block paving are:

  • Enhances the colour of paving
  • The growth of weeds and moss is inhibited
  • Jointing sand is bonded and stabilised
  • Future cleaning becomes easier and less time-consuming
  • Oil and other stains can be removed with relative ease
  • Efflorescence is reduced
  • The surface is fade and weather resistant

Here are the basics for refurbing weedy & mossy block paving:

1: Pressure clean surface (do not leave any growth in the joints)
2: Treat with Paveclean or Paveclear
3: When dry, brush kiln dried sand into exposed joints
4: Apply paving sealer when surface is dry

Remember: Only re-sand joints when you can seal immediately afterwards.

A word on pressure washers: 

To complete a full refurb you are going to need to use a pressure washer, small jet washers that have pencil jet nozzles are not the ones to use.


For speed and to achieve a professional finish you will need to use a machine that has either a dirt blaster nozzle, cyclone nozzle, or a turbo nozzle. 


You can hire a pressure washer and a flat surface cleaner (just like the professionals use) from most tool hire shops or you can purchase them.
