Why should you re-apply kiln dried sand to your paving?
When block paving is laid it is the kiln dry sand that is brushed into the joints, then compacted that gives the overall structure of your paving it’s strength. It does this by forcing the blocks against each other. A really rough idea is this, imagine if you stand in the frame of a doorway. The side frame to either side of you is the paving blocks and you are the kiln dried sand in the joints (I know, sounds silly) put your arms hands against each side of the frame then push outwards. This is similar to what effect the compacted sand does. It locks the pavers together. Keeping them stable. If this sand becomes loose or is removed the pavers then can begin to wobble and become unstable. This can then lead to your paving sinking because of the ingress of water. Or allow large rooted weeds to grow in the joints. So it is always best to reapply the sand whenever it is possible.

- Clean your paving. It’s not always necessary to clean your paving buy it helps if your paving is clean as dirt and weeds or moss could be growing in the joints of your pavers for removing this allows the sand to flow easier into the joints.

- Allow the block paving to fully dry. This usually takes a few days. The surface and the joints need to be completely dry. The joints between the paving bricks need to be dry to allow the free-flowing of the kiln dried sand into the joints of the paving. If the paving is damp the sand particles will stick to the sides of the paving. This will not fill up the joints between the paviors completely from the bottom.
- How much sand is needed? As a rough guide you will need between 1 x 20-25 kg bag of kiln dried sand per 15-30 square meters of paving to be re-sanded. This depends on the width & depth of the paving joints.
- Use a soft broom to spread the dry sand across the surface of the paving allowing the sand to flow into the joints of the paving. Remove all excess sand but ensuring that the joints are full to the top of the bricks.
- Finish by cleaning up any excess sand and re-bag the sand to save for any areas you may have missed. Or gets washed away when it rains. Remember to store the left-over sand in a dry place.
