Product Information
Full details
This B&Q Kiln Dried Paving Sand is an essential material for homeowners and contractors looking to finish or maintain block paving and patio surfaces. Its primary benefit is the fine, dry consistency that flows easily into narrow joints to stabilize blocks and prevent movement over time. While it is perfect for joint filling, it is important to note that this product is strictly for jointing and should not be used as a structural bedding sand for laying pavers.

FAQs
Can I use this for mixing concrete?
No, this is specifically graded for joint filling. It lacks the coarse aggregate needed for structural concrete mixing.
Is this sand safe for pets?
Yes, this is inert natural sand and does not contain toxic additives.
How many bags do I need?
Coverage depends on the width and depth of your joints, but having 200kg available covers most standard residential driveway or patio touch-ups.
Do I need to seal the sand after application?
You do not have to, but applying a liquid paving sealer after the joints are full can help harden the sand and prevent erosion.
Can I store the bags outside?
Only if they are covered and raised off the ground. Exposure to rain or ground moisture will cause the sand to clump.
Troubleshooting
Sand is clumping and not filling the joints
The sand has likely absorbed moisture. Ensure the application is performed on a dry day and the pavers themselves are not wet.
Sand is washing out after heavy rain
This often happens if joints were not filled completely or if the paving lacks a proper edge restraint. Ensure joints are filled to the correct height and check your perimeter blocks.

- Convenient 20kg bag sizes for manageable handling

Setup, Compatibility & Care
Before starting, ensure your paved area is completely dry, as moisture will cause the sand to bridge over the gaps rather than filling them. To apply, pour the sand onto the surface and sweep thoroughly until joints are full. Excess sand should be swept off to prevent staining. For maintenance, keep the bags stored in a dry, covered area to prevent ambient moisture from compromising the kiln-dried quality. This product is compatible with most standard concrete block pavers but should never be used as a substitute for sharp sand or grit when creating a structural bedding layer, as it lacks the load-bearing properties required for that purpose.
