ProSpec Parking Lot Crack Filler comes in a direct-fire blend and an indirect-fire blend. It is specially formulated for maximum adhesion and able to expand and contract with the full range of daily and annual temperature changes.  This allows it to be applied in various regions. The hot application helps it bind to the asphalt while seeping into the pavement cracks. This product is recommended for 1/4″ – 1/2″ cracks. Both materials are available for purchase by the box (priced per box) or by the pallet (priced per pound).
