Dear Expert: How can I prevent weeds and ants from coming through my pavers?
A: Apply joint stabilization sealer or use polymeric sand in the joints instead of coarse, washed sand. Polymeric sand can be brushed into the joints between the pavers, then lightly misted with water. The water activates the polymers that bind the grains of sand together, creating a solid yet flexible joint. Polymeric sand will not wash out of joints and will maintain its bond season after season. Always follow manufacturer’s instructions before use.
