finishing in freezing weather


So, I've got to float(bed) a house. Long story short.....the temperature here will be in the upper twenties the morning following the float day. I use usg blue mud to float. I usually have to give it two days to dry. It won't be completely dry on the night/morning that the temp will be in the twenties. House is NOT heated. Question is: should i wait till the next day when temps will be in the mid to upper 30's. Needing some more input to ease my mind. Thanks guys.

p.s. I had a float freeze on a house once....wasn't pretty.

eastex....

man buddy i feel for you. im a drywall subcontractor and we're obviously facing the same challenges with this cold weather (20s - 40s), just like every year :P


hate it. KILLS my production.

anyways, its always a balancing act for me.......and riding the fine line of whether we should heat the house (cooking the drywall which i dont prefer) ourselves with heat fans, or just wait it out....

a portion of my business is dedicated to production homes...which have tight schedules of course and lower quality....so i dont have a choice BUT to heat the houses (close all windows, and move from room to room....pay someone 8 bucks an hour for the whole day to do this).

however, the main portion of my business is large, custom homes and small commercial buildings....and i basically tell the contractor that if they want a good job on a 1-3 million dollar home or office bldg....a weeks worth extra of drying time isnt gonna kill anyone...unless they want us to go back in 6 mos to a year (which i will charge them for if they dont want to wait a week more in drying).

so eastex, i dont think i was that much help......but theres literally nothing us drywall guys can do but explain this upfront to the client/builder. it's the nature of the beast, not really anything we can do.

although im sure there are users on here who think theyre drywall gods and will say otherwise.

anyways, on all my contracts and proposals, i always state that when our 'winter schedule' is in effect, we need at a minimum 48 hrs PER coat of necessary drying time. if in any case other than that, we are not responsible for anything under a 48 hour (or subcontractors discretion only) time frame. and any decent drywall contractor is going to do a level 4.......as in three separate coats.

roughly, what i find has worked.......is tell the customer/builder that one week per 1000 sf of floor footage is needed.

for example, i just finished a 5000 sf house.....so that equals 5 weeks........theoretically 1 week hanging......2 weeks finishing.......1 week texture....1 week miscellaneous.

this always seems to work for me......although 60% of the time, you will get done sooner than what i described above. but if you state it out ahead of time, it always protects you.....i KNOW a 5000 sf house, i can get done (even in this winter schedule) within 3.5 weeks, but i'll always buy myself as much time as possible, because its construction and ANYTHING CAN HAPPEN.

a job that takes me 2 days, i'll tell the contractor 7 days -- JUST to be safe.


again, i know i wasnt that much help as far as drying times.....but its just the way the ball rolls with drywall.

:P

good luck man.

Re: finishing in freezing weather


at least 55degrees or no mud/tape goes on the way, no heater, no work. Simple, One way to do it, the right way. Floating and it freezing before it dries=uh oh

Nothing sucks more than cold weather and insufficient heat.

Re: finishing in freezing weather


If they can't heat the house, I don't do the job. No more questions. I will furnish an electric furnace and hook it up if the gas company hasn't come. But they have to have permanent heat when I leave. It will ruin the house if it is under fifty degrees in there. Some contractors are tight wads. I get tired of this argument. I don't work for those guys anymore. It gets cold every year about this time. They have to have heat in every house sooner or later. What in the world do they expect?

Re: finishing in freezing weather


Matter should be between drywall contractor & GC/Builder. Shouldn't be your problem, but don,t put on the mud w/o heat in place, temp or otherwise

Exactly.

Heat, (or at least a constant temperature) is VERY important not to just wallboard and mud compound, but more importantly to the wood lumber -- of course im talking about structures such as homes. this doesnt apply to tiny patchjobs of course.

Tim is exactly right ...and this is the problem my company is dealing with right now, at this very moment.

WOOD FRAMING WILL EXPAND AND CONTRACT WITH CHANGES IN TEMPERATURE AND HUMIDITY. DEPENDING ON THE TIME OF THE YEAR, WOOD DRIES OUT, SHRINKS, OR ABSORBS MOISTURE AND EXPANDS. THIS CAN LEAD TO AN ASSORTMANT OF DRYWALL ISSUES SUCH AS NAIL POPS, CENTERLINE CRACKING, VISIBLE JOINTS AND RIDGING.

bottomline, generals (and homeowners) NEED to be more educated when it comes to drywall and lumber.

Im sick of sounding like im making excuses for my company, when the problem is not our workmanship, but the lumber expanding and contracting due to weather extremities.

ive now put an addendum on my contracts that the owner/builder has to sign making them aware of the issue -- and that if they dont provide the proper heating and temperature control, that cracking MAY occur in the future. this addendum relieves me from hearing the general or owner on my back for 'taking forever' on the drywall. i put that in extreme weather under 50 degrees, EACH COAT has to allow at a MINIMUM 48 hrs to dry and that a constant temperature of 60-65 degrees at least is recommended throughout the house, BEFORE and AFTER drywall is installed.

EDUCATE yourself and others. us drywall guys NEED to stick together.

these articles are gold. you guys will either already know about these issues, or may be new to it.......eitherway, EDUCATE yourself more, and pass these around.

as a drywall subcontractor, im getting SICK of being blamed for issues that are out of our control.

Re: finishing in freezing weather


Amen Brother!! Preach it!
It does wear a person down. Always at the beginning of the winter.
I tell them the house has to maintain at least 60 degrees for at least 30 days
after I am done. This allows some time for the paint to cure also. Read the can, it says 30 days to cure paint. Same goes for drywall mud. Let's see, pay 300.00 for some heat and keep from ruining a 10,000.00 drywall job. Sort of a toss up, I know.
