DIY: Replace popcorn ceiling with coffered ceiling in ONE week
After my super long DIY Curved Staircase project, I wanted to do something a little easier for a fast win so I decided to tackle my ugly-outdated popcorn ceiling in my family room.
Here is what you will need for this project plus about 60 hours (less if you buy the wood all dressed and primed). To save money, I purchased all of my wood directly from the lumber yard: rough sawn.

Here is the before picture of my dated family room

Removed the popcorn ceiling and install the layout nailing strips. You can use 2x4s for this but I wanted a perfectly true edge so I ripped it from my spruce plywood and build them up so that they are exactly 3-1/2” by 1-1/4”. I was careful to make sure these are as square as possible.


After I have my layout all marked out with my nailing strips. I installed the 1/4” MDF sheets. I pre-finished these MDF prior to install because I hate painting up-side-down.



The next step is to build up the sub-frame blocks for the coffer so that I have something solid for me to nail the coffer to. Here are the blocks. I made 72 of these.

Installed the blocks on the nailing strips.


Once the blocks are up, I can install the coffer. I made sure they are perfectly level with a laser leveller. Use shims if needed.

Finally, I get to install the crown moulding. This is my first time installing crown moulding so I did a lot of research and made this “Crown Stop” jig. It is a MUST if you want to install crown moulding.

Here is the family room after I installed the crown moulding. Because I took my time to make sure all of my squares are perfectly square and level, installing the crown moulding was a breeze.



The next step for me is to prepare it for paint. But this will have to wait because I want to tackle some other project first….My arch-way to the dining room! It will be so much fun
