Today I patched Joint Compound.
I took a wide trowel to the ceiling, intending to knock off the major peaks, a necessary stage before sanding. I found cracks running the length of the joint compound, many in the corner where to ceiling met the wall.
Why does joint compound never crack where it's convenient?
First there was the large stripe down the center, a narrow, straight crack that defied a simple swipe of the trowel, and demanded I build a berm and feather it into the surrounding ceiling.
Then there was the corner. A flat trowel was a better tool, as a right angle trowel would ave covered the area with another thick layer. I needed precision patching.
Now I must wait, and let the Joint Compound dry before patching again.
