SANDLOCK Additive
Can be mixed with joint sand on the job site. Mix approximately 3-4 pounds of SANDLOCK for every 100 pounds of joint sand, sweep into joints with a broom. Continue spreading SANDLOCK Additive with a broom during compaction until joints are full. Sweep off excess SANDLOCK ADDITIVE, followed by a blower to further clean the surface, then activate by gently saturating the surface with water. Then let it set. NO additional steps are required.
