Laeto Kiln Dried Silica Sand for Block Paving – 20kg Bag

Kiln dried sand is one of those unsung heroes of a well-finished driveway or patio. This fine silica sand from Laeto is designed to be brushed into the joints between block paving, slabs, and path edgings, locking everything in place and giving the surface a neat, professional look. Because it's thoroughly dried and lime-free, it flows easily into even the narrowest gaps, compacting down to create a stable base that helps prevent individual blocks from shifting over time.

One of the practical advantages over ordinary builders sand is how well it resists erosion and discourages weed growth — not a weedkiller by any means, but a fine, tightly packed joint leaves little room for seeds to take hold. It's also worth knowing that the same sand works well as a top dressing for artificial grass, helping to flatten creases and keep the surface cool underfoot. Coverage is generous: a single 20kg bag will fill the joints across roughly 5 square metres of new block paving, or stretch to around 20 square metres when re-sanding an existing surface.

Application couldn't be simpler — tip the sand onto your paved area, spread it across the surface with a soft-bristled brush, and work it back and forth until the joints are full. It suits both confident DIYers tackling a weekend project and tradespeople who need a reliable, consistent product. With a typical grain size of 0.5mm or finer and around 95% silica content, it's consistent enough to produce a clean, even finish every time.
