Hey folks,


I had to cut out part of my ceiling to repair damage from a toilet leak.
I'm about to reinstall drywall, but I've got a quick question.


It looks to me like there is 5/8" of drywall, then a good 1/8" to 3/16" of mud.
Pic attached. Is that correct or is this some type of drywall that I'm not familiar with? That seems like a LOT of mud/texture was put on.



Whenever I've done any drywall repairs in the past (not often and nothing big), I would just mud the joint and smooth it out. Almost seems like I'd have to put a layer of mud/texture across entire repair area since this is so thick.



Thanks in advance for any explanation and advice!

Looks like you have a veneer plaster over the Gypsum base.
Check if you can determine the color of the paper under the white coating.
If it is Blue it will be a Veneer Plaster.

It could be texture that was floated out smooth, though it doesnt really look like it from the pic...

Or possibly a really crappy texture job that was floated and redone...

Whatever the case, dont use premixed joint compound to fill it with.

Thanks for the reply gents. I'm not seeing any blue paper on it.


So, should this work out fine if I put up standard 5/8" Drywall and tape/mud it blending in to these thicker areas? Even if it was plaster around it and I missed the blue paper?


woodco - why avoid pre-mixed joint compound?

Pre-mixed joint compound & Plaster do not get along together if you are in a very dry area it would work. The Plaster can & will absorb moisture at a very high rate the joint compound cannot with stand the high moisture & will separate from the plaster.
