Applying Setting Sand to Block Paving Joints
This video demonstration outlines the complete process for applying setting sand to block paving joints. This task creates a solid, weed-resistant bond between pavers on patios, paths, and driveways. The footage begins by highlighting the importance of surface preparation. The paving area must be completely dry and free from loose dirt, debris, oil, or grease before work starts. Wearing appropriate protective gear, such as gloves and safety boots, is also recommended during application.
The demonstration shows how to prepare the material by remixing the bag contents to correct any settling that occurred during transport. Pouring the sand into a bucket helps manage the application. The guide advises working in small, manageable sections rather than spreading material across a large area all at once. The sand is poured directly onto the pavers and swept into the joints using a stiff broom. The gaps should be filled to their full depth, typically requiring a joint width between 2mm and 5mm.
Once the joints are full, the video displays the watering technique required to activate the setting agent. Using a hose with a spray nozzle or a watering can, the area is thoroughly soaked. A pressure washer must not be used at this stage. Any excess material is rinsed away gently to leave the surface clean. The product used in this demonstration is Sika Setting Sand, which forms a strong seal.
The final steps of the demonstration cover the drying and curing phase. The surface is safe for walking immediately, but requires time to set fully. Drying typically takes one to two days, depending on the temperature, while full curing takes up to 28 days. If rain is forecast shortly after application, covering the area with a tarpaulin can help to protect the finish while it sets.
