Cold
weather can delay or even prevent proper curing and adhesion. Urethane
adhesives cure times are calculated at 70degress and 50% humidity.
In the shop temperature and humidity can be held close to optimum
conditions. |
|
Sunlight
causes urethane to break down. If you look at your windshield
you will usually see a silver band called a "Frit" around the
outer edge of the glass this is to block direct sunlight from breaking
down the urethane. In the shop the urethane is not exposed to
sunlight during installation. |
|
Storage
Urethane should be stored at temperatures between 65 and
85degrees. When left in trucks the adhesive is subject to
temperatures from way below 0 to 120degrees plus. Sometimes cycling
up and down dozens of times as the truck is parked and allowed to heat up
and cool down. |
|
Time Mobile
installers are expected to complete all the jobs they are allotted.
If they fall behind or need extra help they have none. They must cut
corners or work on their own time to make up. In the shop extra help
is available when needed. |
|
Primers
The most likely place to cut corners and save time is to skip using
primers. If the mobile installer uses primers he must sit doing
nothing until the primers dry. In the shop installers can do other
work while allowing the primers ample time to dry. |
|
Comfort
No one can do their best work when they are miserable. Working
in the rain, snow, heat, or cold will cause most anyone to rush to get
back into the comfort of their truck. |
|
Lost
parts When working in the shop if a part such as a screw or bolt is
dropped it is easy to find on the clean concrete floor. When working
on site a dropped part is often lost in the grass or gravel. |
|
Lost
parts Mobile installers can not possible carry the large supply of
misc. parts that are readily available in shop. If they lose a screw
in the driveway they are likely to leave the hole empty. And you
will find the screw in your tire at some latter date. |
|
Broken
glass Broken glass that fall in your driveway stays in your driveway. |
|
Equipment
Most mobile installers have only hand tools. In shop installers
use powerful vacuums for clean up and air power tools for safe removal and
installation of glass. |
|
Supervision
Mobile installers have no one to check their work and catch errors or
correct bad work habits. |
|
Reference
An installer on the road who runs into a problem has nowhere to
turn. In the shop we have reference books, computer access and most
important other experienced installers to ask for help. |
