Yes, you can sand block paving. Sanding is a crucial step in both the initial installation and the maintenance of block paving. It fills the gaps between the paving stones, providing stability and preventing weed growth.
Why Sand Block Paving?
-
Stability and Strength: A fine, kiln-dried sand, when properly compacted, adds significant strength and rigidity to the paving. The sand acts as a binding agent, holding the paving stones firmly in place. ([Reference: A cushion of kiln-dried sand sits between the blocks, or pavers, as often referred to. This sand is very fine and should be bone dry to ease installation. When swept into the joints, it adds strength and rigidity.])
-
Weed Prevention: The sand filling the gaps between pavers helps prevent weeds from sprouting and taking root, keeping your paving looking neat and tidy.
-
Restoration: Re-sanding is a common maintenance task for block paving driveways and pathways. It can restore a sunken or uneven appearance. ([Reference: step 12 – sanding the gaps of your newly laid block pavers. Restoring A Block Paved Driveway. All we need to do now is sand the joints.])
Important Considerations for Sanding Block Paving
- Dry Conditions: The sand should be bone dry for optimal results and to prevent the sand from sticking together and creating a mess. Sanding in wet conditions is strongly discouraged. ([References: The paving has to be dry when using kiln dried sand for jointing block paving as the sand goes like glue when wet and only makes a mess.; Under no circumstances should you re-sand in the rain. Nor should you just after you have power-washed. In a perfect world the blocks should be left to dry for…])
- Type of Sand: Use fine, kiln-dried sand specifically designed for block paving. Other types of sand may not provide the same level of stability or weed prevention.
- Method: Use a suitable tool, such as a stiff brush or a special sand spreader, to distribute the sand evenly into the joints.
Examples of Sanding in Block Paving Projects
Many online resources demonstrate the sanding process, including YouTube videos showing both initial installation and re-sanding of block paving. ([References: Multiple YouTube links provided show various aspects of sanding block paving.])
