Applying Setting Sand to Block Paving
This video walks through the procedure for pointing block paving using a specialised setting sand. Unlike standard kiln-dried sand, this material hardens when activated by water. This creates a joint that resists weed growth and withstands cleaning with pressure washers. The product shown in this application is Sika Setting Sand, a narrow paving joint filler.
The process starts on a clean, dry paved area. The installer pours the granular compound onto the pavers. Using a soft-bristled broom, they sweep the material into the open joints. Sweeping diagonally across the chevrons helps fill the voids completely to the full depth of the paver. The demonstration includes a compaction step. Striking a piece of timber placed on the blocks settles the sand, removing air pockets.
Cleaning the surface is a mandatory part of the demonstration. The footage emphasises removing all excess dust from the surface before introducing water. The installer sweeps the area thoroughly to leave the block faces clear. Even small amounts of residue can cure on the surface if not removed.
Water activation completes the job. The video shows a watering can soaking the filled joints. The water must penetrate the full depth of the sand. Saturation initiates the chemical reaction that binds the grains. The joints cure to a hard finish that will not wash out during rain or cleaning. The surface typically handles foot traffic shortly after drying.
