Substrate Preparation:

Ensure joints between pavers are free of any contaminants such as soil, vegetation, pooling water, etc.

Application:

After laying the paving, clean and dry the substrate. Do not apply Cemix® Joint Sand to damp pavers. Spread the contents of the bag directly onto the pavers, and use a stiff broom to sweep the contents into the joints. Any product left over the pavers, should be swept clean and then work the entire area with a vibrating plate compactor for a minimum of two passes. Due to the vibration, the Cemix® Joint Sand will settle in the joints and some more Cemix® Joint Sand might need to be poured over and broomed in to fill those gaps. Compact the entire area again. Apply a light even spray of clean water. For large scale commercial applications, please get in touch with the supplier or Cemix® for advice.

Cemix® Joint Sand consists of a uniformly blended, properly proportioned mixture of sands and other additives to improve workability and performance of the product.
