The Ap Kiln Dried Paving Sand (Mansil 40) is designed for homeowners and professional landscapers looking to secure block paving installations with a stable, long-lasting finish. Its primary benefit is the free-running, moisture-free consistency that allows for rapid, deep penetration into paving joints to prevent shifting under traffic. While it provides excellent structural integrity and drainage, users should be aware that it requires a dry weather window for installation to ensure the grains remain free-flowing during the application process.

It is best to wait for a dry forecast. Rain immediately after application can wash the loose sand away before it has been compacted into the joints.
Yes, it is non-staining and safe for use with natural stone edging and paving flags.
Sub-angular grains have sharper edges than rounded grains, allowing them to interlock and create a tighter, more stable bond under pressure.
While it fills the joints tightly to discourage weed growth, it is not a herbicide. Proper maintenance and keeping the joints full is the best way to prevent weeds from taking root.
The amount depends on the depth and width of your joints. As a rule of thumb, have more on hand than you think you need, as filling to full depth is crucial for stability.
The paving or the sand is likely damp. Ensure the surface is bone dry before sweeping and store unused bags in a dry, covered area.
The initial sweep was likely insufficient. Use a plate compactor to vibrate the blocks, which helps the sand settle, then add more sand until the joints are full.
To ensure optimal results, always apply this sand when the paving blocks are completely dry. If the surface is damp, the sand will bridge over the top of the joints rather than falling to the base. For maintenance, check your joints periodically—especially after heavy rainfall—to ensure the sand level has not dropped. If a void is detected, simply sweep a small amount of fresh kiln-dried sand into the gap to maintain the integrity of the paving system. This product is compatible with all standard concrete block paving and natural stone units.
