EVOLUTION POLYMERIC SAND is rated as the number one polymeric sand in the industry. It is available in 3 colour choices, grey, beige, and black. This type of sand needs to be used for the best results. Polymeric sand is highly recommended because once it is applied to the joints, it reacts with misted water and creates a binding agent that helps solidify the sand and locks the pavers together. The best polymeric sand to use is the brand EVOLUTION.
