I have 70 sheets of drywall needed for may basement project. I've had different contractors estimate the amount of drywall compound materials I should have and got different estimates.

For 70 sheets of drywall, how much of the 23 KG drywall premix compound boxes should I expect to use (approximately)?

Is there a difference in the coverage if I use the bag 11kg sheetrock versus the boxed drywall premix? does one provide more mudding coverage than the other?

Thank you.

It depends on the job. If it is cut up into a lot of rooms, you'll have a lot more angles to finish than just one or two big rooms. If there is a lot of corner bead (say for soffits/chases to hide HVAC, etc.) it will take more than just a flat ceiling. Are we talking 70 sheets of 8' or 12' board?? that will make a difference. And I don't use boxes, I use buckets. Buckets have more in them than boxes. The bags contain setting type compound which doesn't shrink as much as ready mix, costs less than a bucket, but doesn't make 5 gallons. If you don't use it all in the allotted time, you have to throw it away. All that said, when I have an average job stocked, I generally order a bucket of mud for every 1000 sq. ft. of drywall and throw in an extra for good measure. Two extra if there's a lot of bead/angles. And this is considering professional finishing. You should get by on 3-4 cans if you're fairly good at finishing. If you're going with box mud, I think it's 4 or 4.5 gallons per box as compared to 5 per bucket. You can do the math.

Ron, I hope that was a typo. 5 gallons per 5 sheets??? You're using waaaaay too much mud, if so...

Age old question...

I am going to bump this one back up. Hope someone can help, I am in the same situation presently.

I have 50 sheets, 4x8 to cover for a basement project.
I am working with 20kg tubs of CGC mud, the option was the 23kg boxes like the OP, which also wanted a pound estimate,
The previous answers were given in gallons, and I do not know how much mud weighs per gallon,

could someone please clarify this, maybe we can get an avg. weight req'd per 1000 sq ft? Or, do you contractors use a per sheet estimated weight?
(32 sq. ft)?

Smaller jobs I just buy a 5g bucket of mud
Larger jobs I buy a few
Store isn't that far away for me

Nice calculator
But that means I have to measure :wink:

I don't often give out this secret stuff, but HERE'S your estimator page.


Wow, great thanks for the link. I know the amount of req'd screws is right on... The amount of tape and primer is also very useful.
Will have to wait a few weeks to see if the estimated weight of mud is correct!

Thanks!:thumbup:

You could glaze coat 5 sheets SEVERAL times with a 5 gallon bucket. I'm sure it was a typo....
