Sealant Gelling in Melter
Overheated sealant---check melter temperature gauges of Crack Sealing Machine
Sealant reheated too many times---choose fresh sealant before Crack Sealing Machine working
Using sealant with short pot life---use sealant with longer pot life.
Sealant cracking or debonding in winter
Sealant too stiff---use sealant that is more extensible at low temperatures
Poor cleaning during installation---improve cleaning
Sealing during extreme hot summer temperatures when joints are at their narrowest---avoid Crack Sealing Machine working during extremely hot temperatures
Joint too narrow for the movement experienced---use wider joints
Joint spacing too long---use closer joint spacing
Incorrect joint configuration, sealant installed too thick or too thin---use correct depth to width ratio.
