EXPERT ADVICE
efficiency. Manufacturers like Crafco integrate numerous fea-
tures to extend longevity – better welds, specialized two-coat
epoxy paint, one-piece component construction, but how you
manage your melter matters. Simple mistakes such as adding
too much sealant, driving with a full tank of sealant, or driving
with the burner on can wreak havoc on your machine. Follow
manufacturer’s guidelines for care. This includes changing
your hydraulic and heat transfer oils as recommended. Old
heat transfer oil can crystallize and result in a very expensive
and time-consuming repair.
5. Follow safety protocols. Crack sealing can be done on the
quietest parking lot or busiest highway. Wherever it’s per-
formed, make sure to use proper personal protective equip-
ment, safety cones, and other tools to reduce any hazard. You
can also enhance safety through your equipment. Melters
with intuitive user interfaces and automated safety controls/
shutoffs can be practical if you have an inexperienced crew or
higher turnover.
6. Employ good techniques. Finally, how you apply sealant can
make a huge difference. Use the technique that aligns with
your objectives. Flush fill if an overlay or other surface treat-
ment is planned in the near future. Overband (max. 1/8"
thick, extending 1" on each side of the crack) on a standalone
repair. Keep the overband tight to the pavement, watch your
flow, and use a squeegee to shape and force sealant into cracks
for optimum performance. Don’t use more sealant than neces-
sary as it will be messy and reduce your pavement’s skid resis-
tance. And never try to crack-seal potholes, alligator cracks, or
wide cracks (larger than 1.5" wide). Errantly-applied sealant
looks unprofessional and can cost you hundreds or even thou-
sands of dollars a year.
Most important, contact your manufacturer any time you
need support. Using their guidelines along with these tips will
ensure simple, effective crack sealing and great pavement per-
formance for years to come.
