We've worked on a lot of backyard projects and this polymeric sand from Sika Canada Inc. (SikaFastFix) is great and very easy to use! Here's how to apply it: 👍 Make sure the surface is dry 👍 Pour and spread the product over the paved surface 👍 Use a push broom to distribute the sand over the area and into the joints 👍 Pack in the sand in the joints using a vibrating plate 👍 Repeat the steps and sweep the excess sand 👍 You can use a leaf blower to make sure you have removed the excess sand
