No matter what type of equipment is used, the crack should be filled with sealant material from the bottom to the top of the crack to prevent air bubbles from forming. The air bubbles create weak spots in the sealant. Pour only the amount of material that will fill the crack. Don’t try to completely fill the crack because it is a waste of filler. Coat the vertical surfaces of the crack with a small excess of filler deposited in the bottom of the crack. To prevent tracking, the filler should be 1⁄8 to 1⁄4 inch below the top of the crack. If necessary, use a squeegee to remove excess sealant on the pavement surface, and then blot with sand or limestone dust.
