UltraMix Paver Joint Sand goes through a proprietary natural color infusion process during manufacturing that makes it perfect for use with today's many vibrant and colorful hardscaping products. UltraMix is a specific gradation of sand that meets and exceeds joint material standards yet maintains a natural look for optimal finish. Common joint sands are normally available in only 1-2 colors and can appear mismatched creating an unpleasant aesthetic.
