Cordless drywall screw gun

Parnelli does the name Luker ring a bell. Or Larry Smith?

[Parnelly]

Parnelli, an excellent explanation in layman's terms. And I always thought the drywallers were speaking gibberish. Not really, just another language amongst themselves. I'm struggling with the difference laying down or standing up a sheet makes a difference to how air movement and thus fire migration is effected. I'm a bit of a slow learner, but I'll have an eureka moment soon.

 

Excellent. Thanks.

 

Not the best pictures but these may help.

 

 

 

The first picture shows a fire rated system. The second, is a typical installation, for housing, or non rated walls.

No not familiar with either names.

Parnelly - In your second sketch how do I mud the vertical butt joint? Is the edge of those two 4' adjoining sheets square? Unlike the 8' horizontal edge has a factory taper for mud coverage.

[Parnelly]

Butt ends of the sheets "should" be square. When making a butt joint, its best to only use factory ends. Mudding a butt, requires it to be feathered out significantly more than a standard beveled edge. Try to keep the butt joints as tight as possible.
