GAP Mastic Crack Repair

Overview
Cleaning
Heat Preparation
Priming
Lift
Leveling
Topping Stone
A road crew prepares a raveled and depressed area with primer prior to application of GAP Mastic.

Just as it is important prior to painting, priming can be an important maintenance step between pavement preparation, cleaning, and the actual mastic application. Priming adds a temporary waterproof layer, neutralizes remnant dirt and dust, and provides a better bonding environment for the sealant material.

Using GAP Primer, spray a thin layer along the surface of the area to be repaired.

Next Step: Lift
