Product Details
Kiln Dried Paving Sand 25kg is a fine, dry silica sand supplied in a 25kg bag, specifically designed for brushing into the joints of block paving and paving slabs. Its kiln-dried, moisture-free composition allows the sand to flow easily into narrow gaps, locking paving blocks together, preventing movement, and helping to stop weed growth. This sand is ideal for use on patios, driveways, and pathways, both for newly laid paving and for topping up joints after cleaning or weathering. It should be used dry and is not suitable as a bedding layer or for mixing into mortar. Alternative names like jointing sand or block paving sand are often used depending on whether the focus is on filling joints or the type of paving being installed.

Frequently Asked Questions
How much coverage does a 25kg bag of kiln dried paving sand provide?
A 25kg bag of kiln dried paving sand typically covers approximately 10-15 square metres when brushed into joints, depending on the width and depth of the joints. Wider joints between larger paving slabs will require more sand than narrow joints between blocks.
What's the difference between kiln dried paving sand and regular sand?
Kiln dried paving sand is specially processed to remove all moisture, making it flow freely into narrow joints. Regular sand often contains moisture which can cause it to clump and not settle properly into joints, reducing its effectiveness for locking paving blocks.
Can I use kiln dried paving sand as a bedding layer for paving?
No, kiln dried paving sand should not be used as a bedding layer. It's specifically designed for brushing into joints only. For bedding layers, you need a coarser sand or concrete mix that provides structural support.
How do I apply kiln dried paving sand to block paving joints?
Simply pour the dry sand over the paving surface and use a soft brush to sweep it into all joints. Work diagonally across the surface to ensure complete filling, then brush away excess sand and lightly compact if needed.
Will kiln dried paving sand prevent weeds growing in my patio joints?
Yes, when properly applied, kiln dried paving sand fills joints completely, creating a barrier that significantly reduces weed growth. However, over time weathering may create small gaps where seeds can settle, requiring occasional topping up.
