| Winter is Coming-Part III |
Several years ago (9/97), we
advised the users of our products of the negative effects of low temperatures and moisture on drywall
finishing materials. Over the past three to four winters, severe cosmetic cracking has occurred
throughout the marketplace.
We have been proactive in efforts to determine the cause(s)
of these cracking problems and were instrumental in the formation of a group to study the construction
process for possible solutions. While no single factor could be isolated, it became evident that a
high percentage of the cracking can be avoided by improving job conditions, proper scheduling and
proper application of the gypsum wallboard. |

All industry recommendations
require that the structure be heated to a minimum temperature of 50º F for a period of 48 hours prior
to the application of gypsum wallboard, 60º F during application of finishing products, and that the
structure be maintained at that temperature through completion (final decoration). We further recommend
that new unoccupied structures be stabilized at 50º F minimum until occupied.
Without a doubt,
the preferred method of heating is to utilize the forced air units installed in the structure. These
systems not only provide heat, but also expel moisture. The use of diesel or kerosene heat can produce
discoloration. Propane fueled space heaters actually produce 7.8 pounds of water per gallon of propane
burned. This adds moisture to the site making adequate ventilation difficult but very
necessary.
It should be noted that all so-called "space heaters", regardless of fuel,
do not provide heat evenly throughout the job. It is extremely important that minimum temperatures be
maintained continuously and that there is adequate ventilation to remove moisture. |
|
| In some areas, as little as
three days are scheduled for drywall finishing and texture application. We recommend at least seven
days for these procedures. It should also be noted that painting specifications are consistent with
drywall finishing regarding temperature and drying recommendations. |
| A preponderance of
cracking observed on walls takes place on "rips" or "belly bands" which
presents a joint with at least one cut edge and, many times, both cut edges. There is no known
way these joints can be treated to produce a joint equal in strength to those comprised of
paper wrapped "factory" edges. |
| With the experience
gained over the past several years, and the knowledge that we will face severe weather in
the future, we want our customers to be forewarned of the possible problems. Fortunately, we
see some positive actions in some market areas. Builders, subcontractors and building
officials are paying attention. We are not manufacturers making excuses; we are concerned
suppliers to the industry attempting to provide meaningful information to our
customers. |
